Pink eggs and snails: field oviposition patterns of an invasive snail, Pomacea insularum, indicate a preference for an invasive macrophyte. It is native to South America from Uruguay, Paraguay, and the bordering areas of Brazil and Argentina, north to the Amazon River. In parts of South America, large piles of apple snail shells can accumulate under the favorite perches of snail kites (R.H. Cowie, personal observations). Species identification from archived snail shells via genetic analysis: a method for DNA extraction from empty shells. 43 (4), 535-540. http://odokon.ac.affrc.go.jp/ DOI:10.1303/aez.2008.535, Rawlings T A, Hayes K A, Cowie R H, Collins T M, 2007. Hawaii Journal of Medicine and Public Health, 72(6, Suppl. Genetic divergence of the genus Pomacea (Gastropoda: Ampullariidae) distributed in Japan, and a simple molecular method to distinguish P. canaliculata and P. insularum. People may also move it around accidentally; for instance, eggs can be transported on boats (EFSA Panel on Plant Health., 2012), and in Hawaii small juveniles (of P. canaliculata) could be inadvertently transported on taro parts used for propagation (Levin et al., 2006). Seasonal patterns have not been studied in the native range of P. maculata. However, given its success as an invasive alien species it is not surprising that the majority of clutches display high hatching success, often 70% or more (Barnes et al., 2008). The foot is oval with a squarish anterior edge. Another invasive apple snail, Marisa cornuarietis, has been suggested as a biocontrol agent for invasive weeds. In a few cases in the USA, managers have tried hand removal of snails and eggs as a strategy to reduce population size and growth. Although the shells of many Pomacea species may be extremely variable, the shells of some species are sufficiently characteristic that they are readily distinguished from P. maculata. The information has not received final approval by the U.S. Geological Survey (USGS) and is provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the information. Populations of P. maculata in Charleston, South Carolina, USA, probably experience the coldest temperatures in the introduced range, although climatic modelling indicates suitability of areas a little further north (Byers et al., 2013).

(2007) possess COI haplotypes that are a close match to haplotypes from the Río Uruguay near Buenos Aires, indicating a probable origin in this region. Furthermore, such feeding attempts may prove unsuccessful. In: A handbook of global freshwater invasive species [ed. by Joshi, R. C.\Sebastian, L. S.]. (2009) tested feeding rates of adult P. maculata on 15 aquatic plants in non-choice experiments. Southeastern Naturalist 16(3):N14-N18. Similarly, following the introduction of P. maculata to Spain, climate matching combined with two global warming scenarios identified areas in Europe that may be susceptible (EFSA Panel on Plant Health, 2012). 10. It may out-compete native apple snails (Halwart, 1994a; Warren, 1997), prey on native fauna (Wood et al., 2005, 2006) and alter natural ecosystem function (Carlsson et al. 'Snail Busters' apple snail trap as deployed in shallow water. Reported ... Pomacea haustrum. Table 1. (2012) described a case study of repeated copper sulfate application to Langan Pond and Three Mile Creek in Mobile, Alabama. Nontheless, it can be assumed that P. maculata was introduced for the same reasons as was P. canaliculata, even if it was not distinguished from the latter. The shell spire is generally low but variable. Tsukuba, Feb.25-27, 1997, pp.170-180, Wada T, 2006. by Joshi, R. C.\Sebastian, L. S.]. Established in Florida, Georgia, Texas (Rawlings et al. Gainesville, Florida, USA: United States Geological Survey. Similarly to other species, P. maculata showed intermediate preference for Bacopa caroliniana and N. odorata. There are four species of Pomaceain Florida, one of which is native and considered beneficial (Capinera and White 2011). Island apple snail is a valid common name for the species, but Armstrong says he now refers to the species in Alabama as the maculata apple snail for specificity. Differences in shell morphology are most notable in newly hatched juveniles. Biological Invasions 20:137–149. The molecular genetics of P. maculata has been less studied than that of P. canaliculata, although the two species, previously difficult to distinguish, can now be readily distinguished based on DNA markers; they are not sister species (Hayes et al., 2008, 2009b, 2012). BMC Evolutionary Biology. Pomacea maculata; aperture view of large shell that has been cleaned and briefly bleached. The shell coils dextrally – that is, when viewed with the apex uppermost the aperture is on the right side of the shell. In general, the former is the primary risk in Asia and the latter in other regions, though by no means exclusively. in South America (Perera and Walls, 1996). Position and number of penial sheath glands for a number of ampullariid species have been tabulated by Hayes et al. Hayes et al., 2009b; Matsukkura et al., 2013). 72 (6, Suppl. In: Molluscs as crop pests. Hatchlings are likely to rely on detritus and algal-based resources for food, although they also readily consume lettuce in the laboratory. (2007), Hayes et al. When several references are cited, they may give conflicting information on the status. P. maculata in the southeastern USA was probably introduced via the aquarium trade (Karatayev et al., 2009; Martin et al., 2012). The Invasive Species Compendium datasheet for P. canaliculata should be accessed for much information regarding prevention and control related to P. canaliculata, as the same information is mostly pertinent also to P. maculata. © Copyright 2020 CAB International. Applesnails. No mixed species populations were reported by Hayes et al. Miller, and W.M. cuprinaReeve, 1856, leviorSowerby, 1909, lineataSpix in Wagner, 1827), or mis-spell the genus or species names (e.g. They are held in place when the secreted mucous dries (Andrews, 1964). For example, a number of studies have been undertaken on consumption of plants by apple snails in Laos (Carlsson and Lacoursière, 2005; Carlsson and Brönmark, 2006) and Thailand (Carlsson et al., 2004a). Most of the literature on management of apple snail pests undoubtedly refers to P. canaliculata, which is the most widespread introduced species of Pomacea in Asia. The operculum (the trap-door like structure attached to the upper part of the animal’s foot and used to close the shell aperture when the animal withdraws into the shell) is dark brown; it is horny (corneous) in texture and somewhat flexible, and is uniformly concave in females, but concave at the centre and becoming convex toward the margins in males. Applesnails are larger than most freshwater snails and can be separated from other freshwater species by their oval shell which has the umbilicus (the axially aligned, hollow, cone-shaped space within the whorls of a coiled mollusc shell) of the shell perforated or broadly open. (2007), and given the common name ‘island apple snail’ (‘insularum’ in Latin means ‘of islands’) by various agencies. Kyle et al. There were some differences in consumption between congeneric plant species.

The effectiveness of different control strategies and the potential for “invasional meltdown” (Simberloff and Von Holle, 1999) with other exotic species such as taro (Colocasia esculenta) also warrants further investigation. Overall, they applied four tons of copper sulfate in an attempt to prevent the snail invasion from reaching the Mobile-Tensaw Delta. (2013) provided a model that predicted suitable habitat for P. maculata in the USA, based on climate modelling and the influence of pH. 2008. (15 cm) high and are higher than they are wide. These egg masses are very noticeable and can even be seen from a moving vehicle. They also noted rarely seeing juveniles despite high egg production. Martin CW, Bayha KM, Valentine JF, 2012. Introduction of the apple snail Pomacea canaliculata and its impact on rice agriculture. Wetlands, 28(2):544-549. http://www.bioone.org/doi/abs/10.1672/07-11.1, Howells RG, Burlakova LE, Karatayev AY, Marfurt RK, Burks RL, 2006. In particular, P. maculata can be distinguished from P. canaliculata on the basis of the position and number of glands on the penial sheath, P. canaliculata having two distinctive areas of glandular tissue in the apical penial sheath gland, and P. maculata lacking a medial sheath gland but possessing a basal sheath gland (Hayes et al., 2012, 2015). Common Name. Eradication may be possible for small, established P. maculata populations restricted to isolated bodies of water. Pila Roding, 1798 and Pomacea Perry, 1810 (Mollusca, Gastropoda): proposed placement on the Official List, and Ampullariidae Gray, 1824: proposed confirmation as the nomenclaturally valid synonym of Pilidae Preston, 1915. While some people might see this as an environmental service, apple snails such as P. maculata that feed relatively indiscriminately on a wide range of macrophytes will have negative impacts on native and desirable vegetation and the animals associated with them (Robins, 1971; Simberloff and Stiling 1996; Cowie, 2002). One or more of the features that are needed to show you the maps functionality are not available in the web browser that you are using. To assess chronic tolerance, snails were maintained at the experimental temperature for 28 days. Hydrobiologia [Structure and Function of World Shallow Lakes. Their pH data were from the dissertation of Ramakrishnan (2007), which examined tolerance to environmental temperature (15.2-36.6°C), salinity (0-6.8‰) and pH (4.0-10.5). In: Biological Conservation, 78(1/2) [ed. 2007) and Louisiana, and most likely where there is evidence of egg masses, often first noticed prior to adults. Kyle et al. Specifically, P. maculata also quickly consumed S. latifolia after eliminating the Utricularia. Deliberate introduction for food may therefore now be rare. Although a useful control method for an early detected, small invasion of P. maculata, hand removal of adults is time consuming and some snails can still go undetected making the control treatment ineffective (Martin et al., 2012). Applesnails are tropical to subtropical organisms and cannot survive below 50°F in the winter (Florida DOACS, 2002). However, the apical gland of P. maculata is distinguished from that of P. canaliculata by lacking a rugose central glandular surface bordered by smoother glandular tissue. Genetic divergence of the genus Pomacea (Gastropoda: Ampullariidae) distributed in Japan, and a simple molecular method to distinguish P. canaliculata and P. insularum. in Japan (Matsukura et al., 2013). However, mixed and possibly hybridizing populations have now been detected, e.g. Due to the confusion in species identification, it is impossible to determine exactly when P. maculata was initially introduced to Asia, much less into individual countries. http://www.aphis.usda.gov/wps/portal/aphis/ourfocus/planthealth, USGS, 2013. CABI is a registered EU trademark. Individual growth rates vary widely. Pages 145-192 in Barker, G.M., ed. Hayes K A, Joshi R C, Thiengo S C, Cowie R H, 2008. Micronesica, No. http://nas.er.usgs.gov, Wada T, 1997. The number of eggs per clutch ranges from a few hundred to as many as ~4500, with an average of ~1500 (Barnes et al., 2008; Burks et al., 2010). Generally, the patterns of host plant consumption by P. maculata were similar among the above studies, although with a few exceptions. In: Global advances in ecology and management of golden apple snails [ed. Non indigenous land and freshwater gastropods in Israel. Pomacea maculata Pomacea maculata. The snout is short, squarish and with lateral, anterior tips elaborated into long tapering labial palps. However, the rapid spread of P. maculata within Asia following introduction has been predominantly human mediated. Further research especially on its genetics, reproductive biology and physiological tolerances are required. Radular morphology of Pomacea maculata (a & c) and Pomacea canaliculata (b & d). The primary pathways of intentional introduction by people have been the aquaculture industry and the aquarium trade (Cowie, 2002; Cowie and Hayes, 2012). Texas Parks and Wildlife Department, Management Data Series No. Biological Invasions. The distribution in this summary table is based on all the information available. Based on field and other observations of the snails in the USA and on the architecture of the plants, C. esculenta, Pontederia lanceolata, Sagittaria spp., Eichhornia crassipes, Pistia stratoites, Alternanthera philoxeroides, Schoenoplectus californicus, Scirpus maritimus, Thalia dealbata and Typha latifolia could provide a suitable substrate for P. maculata females to lay egg clutches. No study has yet documented the potential or limitations for reproduction in the species but anecdotal observations suggest that mature female snails can lay one clutch every 7-10 days, with clutch size ranging widely but averaging over a thousand eggs per clutch (Barnes et al., 2008; Burks et al., 2010). However, much less has been written about the invasiveness and pest potential of ‘P. Can breathe air. As in almost all studies undertaken on Pomacea in East and South-East Asia, especially prior to the rigorous distinction of P. canaliculata and P. maculata by Hayes et al. While larger adult snails of some species are relatively easily distinguished, small juvenile snails sold in the pet trade are much more difficult to distinguish, especially by a non-expert. Juvenile snails, adult appetites: contrasting resource consumption between two species of applesnails (Pomacea). The availability of large snail populations in these areas might draw attention to their culinary potential and result in the creation of an aquaculture industry where one did not formerly exist. Island apple snail is a valid common name for the species, but Armstrong says he … Patterns of consumption did not differ among size classes or across a range of temperatures (20-35 °C). Other members of this genus can carry > 10°C, Cold average temp. Apple Snails As with any invasive species, apple snails will overpopulate and steal resources away from native species, disrupting natural ecological processes. Citation information: U.S. Geological Survey. The most northern latitude at which P. maculata populations occur is the Ebro River delta in Spain (EFSA Panel on Plant Health, 2012; Horgan et al., 2012; Andre and Lopez, 2013), where it has been introduced. Along with P. canaliculata, pro-active states (i.e. 3, Supplement:51-62, Morrison W, Hay M, 2010. Invasions in agriculture: assessing the cost of the golden apple snail in Asia. Adult P. maculata can reach up to 165 mm in shell height and weigh over 200g (Kyle et al., 2009; Hayes et al., 2012). (2008) were of just one species, suggesting that most initial propagules were also not mixed. ... Pomacea diffusa. Snails survived by filling their shells with air and floating away from the pesticide application. The following brief description is modified primarily from that publication, with other citations indicated as appropriate. Biological Invasions, 15(9):2039-2048. http://rd.springer.com/article/10.1007/s10530-013-0431-1, Matsukura K, Okuda M, Kubota K, Wada T, 2008. The snails consumed duckweed in one piece but first attacked the roots and aerenchyma-filled bulbs of water hyacinth before consuming the leaves. P. paludosa is the only native North American species of Pomacea, occurring in southeastern USA and Cuba. Pest risk analysis on the introduction of Pomacea insularum into the EU. The majority of references identify Argentina as the original source of the introduced Pomacea (e.g. Impact and control of introduced apple snail, Pomacea canaliculata (Lamarck), in Japan. Alabama, Louisiana, Mississippi, Georgia) should be encouraged to adopt similar measures. Acta Oecologica, xxx: 1-12. http://dx.org/10.1016/j.actao.2012. In the native habitat, mounds of shells often indicate the presence of snail kites. They also inhabit nearly all ecosystems. Wada, 2006). The acute upper lethal limit was below 42°C. This aspect of their biology warrants further study, especially in comparison with P. canaliculata, as it may be important in the ability of P. maculata to invade agricultural wetlands. (2018) suggests that the development of all-male prawn populations of Macrobrachium rosenbergii has the potential as a biocontrol agent over hatchling and adult apple snails (Pomacea spp.). Washington, USA: Island Press, 101-108, Way MJ, Islam Z, Heong KL, Joshi RC, 1998. Pomacea maculata; mating pair. In fact, no published study has suggested that P. maculata consumes substantial quantities of E. crassipes quickly. Female and male snails copulate for several minutes, if not hours. Establishment of the invasive island apple snail Pomacea insularum (gastropoda: ampullariidae) and eradication efforts in Mobile, Alabama, US. Effect of temperature and feeding preference on submerged plants by the island apple snail, Pomacea insularum (d'Orbigny, 1839) (Ampullariidea). maculata’. The former has probably been the main source of the invasion of P. maculata in Asia, while its presence in the continental USA is probably attributable to the latter. There is much less knowledge of the general biology P. maculata than for the more well-known P. canaliculata (Hayes et al., 2015). Biology of the golden apple snail, Pomacea canaliculata (Lamarck, 1822) with emphasis on responses to certain environmental conditions in Sabah, Malaysia. Although the snail kite can feed on P. maculata as an alternative, it often uses more energy trying to extract P. maculata from their shells and may use more resources flying back to suitable feeding perches (Cattau et al., 2010). Raising public awareness is not only important to prevent the further spread of Pomacea species in Asia and elsewhere (e.g. Overview Origin Pomacea maculata is a species of large, globular, freshwater snail native to tropical and sub-tropical South America. Those species synonymized with P. maculata are listed as “Other scientific names” in the section on Identity in this P. maculata datasheet. PhD Dissertation. In the USA transport of all ampullariids except Pomacea ‘bridgesii’ (incorrect identification of P. diffusa) between states is restricted (Gaston, 2006).

The range reported incorporates speculation and anecdotal accounts about P. canaliculata as well. Ludwigia) and plants that occur on the margins of the riparian zone. Los Baños, Philippines: Philippine Rice Research Institute (PhilRice), 155-167, Conner SL, Pomory CM, Darby PC, 2008. P. canaliculata and P. maculata. In Florida, initial control efforts in Wellman’s Pond focused on hand collection of snails but this proved extremely time consuming and ineffective. (2013) found preliminary genetic evidence of hybrid individuals. Once introduced, it is further possible that it spreads naturally by floating downstream, to a limited extent by crawling upstream, during flooding, and even attached to birds, as has been reported for P. canaliculata in Hawaii (Levin et al., 2006). [2020]. In addition, apple snails in general occur on a number of other invasive species watch lists (e.g. Yet it is still possible that these snails could have been P. maculata. Comparing apples to apples: clarifying the identities of two highly invasive Neotropical Ampullariidae (Caenogastropoda). 6th Shallow Lakes Congress, Punta del Este, Uruguay, 23-28 November 2008. Similarly, small watercraft (e.g. When removing nuisance vegetation (e.g. The snail could be incorporated into educational displays in aquariums that teach about wetland ecosystems and some school teachers may use the large shells for art projects. P. maculata showed a lower range of consumption (between 10 % and 34 %) on a second subset of plants (Alternanthera philoxeroides, Sagittaria graminea, Panicum hemitomon, Scirpus maritimus, Canna glauca, Pontederia cordata, S. californicus,). Cutrine, Komeen, KTK-Tea, Captain) or copper sulfate represents the most widely used method of chemical control for P. maculata. Molluscs as Crop Pests. Darden, D.M. Furthermore, the recent name changes (Hayes et al., 2012) complicate matters because permit restrictions may lag behind changes in scientific terminology. In Asia A. cantonensis is widespread in P. canaliculata (Lv et al., 2011), but as yet there has been no report of it in P. maculata. However, experimental evidence (Ramakrishnan, 2007) indicates that P. maculata can survive long periods (i.e. 8 (2), e56812. Island apple snail . Abandonment of the snail farms allowed the snails to escape and become major agricultural pests, as frequently reported for P. canaliculata (e.g. Lethal and non-lethal effects of multiple indigenous predators on the invasive golden apple snail (Pomacea canaliculata). Positive interactions of nonindigenous species: invasional meltdown? Analysis of trailered boat traffic and the potential westward spread of zebra mussels across the 100th Meridian. Pomacea maculata. Among New World genera, the three species of Marisa are readily distinguished from species of Pomacea as they are planispirally coiled (the coils are almost flat) and are thus known commonly as giant ramshorn snails. Eggs are laid noticeably above the water line, from a few centimetres but generally higher and up to ~2 metres. The bright pink eggs of P. maculata are generally thought of as being unpalatable to predators, as are those of P. canaliculata (Dreon et al., 2010). Differences in population dynamics and potential impacts of a freshwater invader driven by temporal habitat stability. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Aquatic Ecology, 48(3):321-326. http://link.springer.com/article/10.1007%2Fs10452-014-9486-z, Matsukura K, Okuda M, Cazzaniga NJ, Wada T, 2013. Immersion of the eggs, especially for extensive periods, reduces hatching success. The list of references for all nonindigenous occurrences of Pomacea maculata are found here. However, no studies on how P. maculata might alter ecosystem processes, particularly nutrient cycling, have been conducted. 7 (97), (26 June 2007). Other states where snails have invaded (i.e. PLoS ONE, No.December:e15059. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Armstrong said the species that is impacting Three Mile Creek is the Pomacea maculata. Molluscan Research, 24:139-148, Thiengo SC, Simões Rde O, Fernandez MA, Maldonado Júnior A, 2013. The functional anatomy and histology of the reproductive system of some Pilid gastropod molluscs. At 30°C, under the most desiccating conditions <5% RH), all of the smallest size class were dead after 56 days, but under the most desiccating conditions (>95% RH), 100% mortality did not occur until day 189. In: Global advances in ecology and management of golden apple snails [ed. Hawai'i Journal of Medicine and Public Health, 72(6, supplement 2):6-9, Cowie RH, 2013. 2017). 2004a). Sometimes intentionally but frequently accidentally (due to taxonomic confusion and difficulty of identification), vendors might sell P. maculata as an aquarium snail for cleaning algae off aquarium walls. A Field Guide to the Birds. Both garden pests rely on their muscular foot to move and the secretion of mucous or slime on which they glide. Regarding chronic low temperature tolerance, all snails died within the 28 day period at 2-15°C, while there was no mortality at 20°C. Snails were exposed to ph in the range of 2 to 12.5 for a period of 28 days.

Life Cycle The thin fragile shells of P.maculata can reach up to in. It may now have reached most areas in which it would be able to live within the region. Establishment of the invasive island apple snail Pomacea insularum (gastropoda: ampullariidae) and eradication efforts in Mobile, Alabama, US. (2008) recorded P. maculata, there were no previous records, the exceptions being Cambodia and Thailand. Nonetheless, the development of the two types of tissue varies with maturity and they may appear undifferentiated in younger individuals. The first relatively comprehensive molecular phylogeny of the genus Pomacea was published by Hayes et al. The initial introduction of this snail into Southeast Asia was intentional, as both a food commodity for export and an important local source of protein. Although usually confined initially to aquaculture facilities, the snails either escape or are deliberately released into agricultural or natural wetlands. The traps use bait to attract adults into the contraption. They estimated the cost of application at $2.50/lb [$5.50/kg]. (2010) they ate a small amount of P. lanceolata. Other species that may be confused with P. maculata are P. lineata and P. dolioides. (2008), Introduced from elsewhere in east or South-East Asia. Burks et al. Even without water stress, not all clutches hatch fully and some fail to hatch at all, perhaps indicating incomplete fertilization. Radular morphology of Pomacea maculata and Pomacea canaliculata.

(2013) reported indivduals with both mitochondrial and nucelar DNA sequences characteristic of P. maculata; First reported: 2008/2013, Keawjam and Upatham (1990) reported 1984 as the first record of Pomacea in Thailand but this record could have been of either P. maculata or P. canaliculata. Ramakrishnan (2007) also measured metabolic O2 consumption (VO2), in particular under progressive hypoxia to assess tolerance of P. maculata to hypoxic conditions. Acta Oecologica, http://dx.doi.org/10.1016/j.actao.2012.10.002:1-12, http://www.aphis.usda.gov/wps/portal/aphis/ourfocus/planthealth, https://www.researchgate.net/profile/Kenneth_Hayes/, Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License. In the aquarium trade, particularly in the USA, stores receive freshwater snails from multiple sources and no mechanisms exist to verify the identity of the snails (Karatayev et al., 2009). Andre KB, Lopez MA, 2013. (2010) noted that P. maculata in Texas laid a disproportional number of clutches on riparian vegetation, specifically taro (Colocasia esculenta). Out of South America: multiple origins of non-native apple snails in Asia. Los Baños, Philippines: Philippine Rice Research Institute (PhilRice), 181-197, Warren GL, 1997. The thin fragile shells can reach up to 6 in. http://www.biomedcentral.com/content/pdf/1471-2148-7-97.pdf, Robins CH, 1971. Other Pomacea species are similar, e.g., Pomacea maculata.. Distribution. Using a similar approach, Morrison and Hay (2011) conducted paired feeding experiments that gave P. maculata the choice between plants found outside their native distribution (i.e. New type material — neotype ( Hayes et al .

Consequently, species boundaries have been very difficult to assess based solely on conchology. Both P. maculata and P. canaliculata, as well as several other species that exhibit similar shell morphology, lay pink clutches above the water’s surface that are readily distinguished from those of a number of other species with similar shell morphology but that lay bright green eggs. Medium-sized and large prawns (10–30 g) efficiently preyed on snails up to 15mm in size, while small prawns (up to 4 g) effectively consumed snail hatchlings. http://www.biomedcentral.com/content/pdf/1471-2148-7-97.pdf. When the first introduction of P. maculata took place is not known. The shells of P. paludosa are smaller, thinner and with a smaller aperture, making them easier to handle than P. maculata, which are then more likely to be dropped. Various other scientific names (tabulated by Cowie et al., 2006) have been used for the introduced apple snails in Asia (i.e., undistinguished P. maculata and P. canaliculata) that place them in incorrect, invalid or mis-spelled genus names (e.g. , 85 ( 6, supplement 2 ): e56812 pH in the (.
