P. canaliculata spread rapidly through much of Southeast Asia following its initial introduction to Taiwan. Photo 3 Florida Division of Plant Industry , Florida Department of Agriculture and Consumer Services, Bugwood.org. The Invasive Species Specialist Group (ISSG), Species Survival Commission (SSC), World Conservation Union (IUCN), 12 pp. The southernmost latitude at which it occurs appears to be near Buenos Aires, Argentina (Hayes et al., 2012; Byers et al., 2013). Journal of Medical and Applied Malacology, 2:45-57, Kim JR, Hayes KA, Yeung NW, Cowie RH, 2014. Heavy snail mortality occurred but eggs were still found the following year. 2012, In Florida, initial control efforts in Wellman’s Pond focused on hand collection of snails but this proved extremely time consuming and ineffective. Ranamukhaarachchi and Wikramasinghe, 2006, EFSA Panel on Plant Health, (2009) tested feeding rates of adult P. maculata on 15 aquatic plants in non-choice experiments. Genetic exchange between two freshwater apple snails, Pomacea canaliculata and Pomacea maculata invading East and Southeast Asia. Los Baños, Philippines: Philippine Rice Research Institute (PhilRice), 181-197, Warren GL, 1997. by Joshi, R. C.\Sebastian, L. S.]. 1984 was the first record of Pomacea but this record could have been either P. maculata or P. canaliculata, Introduced from elsewhere in east or South-East Asia. In: A handbook of global freshwater invasive species [ed. Pomacea maculata is a large freshwater snail commonly known as the Spotted Apple Snail. Consequently, the use of common names should be avoided to reduce confusion within this taxonomically difficult group (Hayes et al., 2009b). The Veliger, 50(3):248-254, Halwart M, 1994. Age or size at first reproduction has not been studied in P. maculata but based on anecdotal evidence, juvenile P. maculata mature and can start producing very small egg clutches at 9-12 months old. Pomacea maculata is a species of large, globular, freshwater snail native to tropical and sub-tropical South America. In their non-native range, they often occur in canal or irrigation systems associated with wetland agriculture. Pomacea maculata; recently dislodged male and female mating pair, with visible male organ extended. Shallow canals at the sides of fields help with collection too. Pest risk analysis on the introduction of Pomacea insularum (d'Orbigny, 1835) into the EU. 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).

No study has adequately documented immediate hatchling growth rates although rapid growth has been observed in the first six weeks. (2009), Baker et al. of coldest month > 0°C and < 18°C, mean warmest month > 10°C, Cf - Warm temperate climate, wet all year, Warm average temp. This appears to be the only broad study of the physiology of P. maculata. Above ph10, all snails died within 2 days (ph12.5) and 22 days (ph10.5). Lethal and non-lethal effects of multiple indigenous predators on the invasive golden apple snail (Pomacea canaliculata). 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. The role of the proteinase inhibitor ovorubin in apple snail eggs resembles plant embryo defense against predation. Along with many other snail species, P. maculata can serve as an intermediate host for the parasitic nematode, Angiostrongylus cantonensis (rat lungworm) (Cowie, 2013b; Kim et al., 2014). Golden apple snail: its occurrence and importance in Suriname's rice ecosystem. Pink eggs and snails: field oviposition patterns of an invasive snail, Pomacea insularum, indicate a preference for an invasive macrophyte. (2010) assessed adult P. maculata consumption on a suite of aquatic plants and macroalgae, and reported per capita consumption (grams plant per gram snail per day) based on non-choice experiments. Pomacea haustrum, common name the titan applesnail, is a species of large freshwater snail with an operculum, an aquatic gastropod mollusk in the family Ampullariidae, the applesnails. 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. beef) with cheaper alternatives might facilitate a resurgence of apple snails in aquaculture, especially in areas that have other non-traditional meat sources. In: Biological Invasions, 11 1963-1972. 145-192. http://www.cabi.org/cabebooks/ebook/20023046840 DOI:10.1079/9780851993201.0145. 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. Snail kites (Rostrhamus sociabilis) are possible biological vectors. The shell coils dextrally – that is, when viewed with the apex uppermost the aperture is on the right side of the shell. http://nas.er.usgs.gov, Wada T, 1997. (2008, 2009b, 2012) and Tran et al. Hawaii Journal of Medicine and Public Health. 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). Impact of invasive apple snails on the functioning and services of natural and managed wetlands. Los Baños, Philippines: Philippine Rice Research Institute (PhilRice), 345-361. Although it is clear that P. canaliculata was first introduced to the region (to Taiwan) in about 1979 or 1980, P. maculata has not been demonstrated rigorously as ever having been present in Taiwan (Hayes et al., 2008). Pomacea canaliculata is a freshwater snail with a voracious appetite for water plants including lotus, water chestnut, taro and rice. However, much less has been written about the invasiveness and pest potential of ‘P. No snails consumed Eleocharis cellulosa, P. cordata, P. hemitomon or Typha sp. (2013) reported COI sequences characteristic of P. maculata but individuals could have been hybrids between P. maculata and P. canaliculata, and it is possible that the P. maculata genes originate from hybrids introduced from the native range. However, above a level of 6.8‰, survivorship declined rapidly, such that at 13.6‰ and above, 100% mortality occurring within 3-7 days. BIOSECURITYThe termite is on the list of the 100 of the World's Worst Invasive Species compiled by the Global Invasive Species Database, maintained by the IUCN Invasive Species Specialist Group. For professional researchers, because of the anatomical, physiological and behavioural adaptations of apple snails, the group in general provides a powerful model for addressing a number of ecological and evolutionary questions (Hayes et al., 2009b). Adults have thin shells, 35-60 mm high, which coils to the right (when apex is uppermost and opening is to the right), and varies from yellow brown, greenish-brown to dark brown, often with bands, with a brown horny operculum which closes the opening of the shell (Photo 1&2). No details of economic impacts exist for P. maculata because of past confusion between it and P. canaliculata. Hawaii Journal of Medicine and Public Health, 72(6, Suppl. The acute upper lethal limit was below 42°C. Comparing apples to apples: clarifying the identities of two highly invasive Neotropical Ampullariidae (Caenogastropoda). In the past, this species has been misidentified as P. bridgesii, which is generally larger. Malacologia, 47(1/2):397 pp, Britton DK, McMahon RF, 2005. The lip of the shell prominently displays the characteristic orange color that helps distinguish this species. States with nonindigenous occurrences, the earliest and latest observations in each state, and the tally and names of HUCs with observations†. Ramakrishnan (2007) also measured metabolic O2 consumption (VO2), in particular under progressive hypoxia to assess tolerance of P. maculata to hypoxic conditions. 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). Ampullaria immersa Reeve, 1856. Freshwater Biology, 56(4):717-734. http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1365-2427, Martin CW, Bayha KM, Valentine JF, 2012. The most readily apparent anatomical differences are in the male penis sheath (Hayes et al., 2012). Knowledge of the biology of ampullariids, essentially as of 1999 and which focussed on their role as agricultural pests, was reviewed by Cowie (2002). Quite the appetite: juvenile island apple snails (Pomacea insularum) survive consuming only exotic invasive plants. Freshwater Biology, 51(4):695-704. http://www.blackwell-synergy.com/servlet/useragent?func=showIssues&code=fwb, Carlsson NOL, Brönmark C, Hansson LA, 2004. Invasions in agriculture: assessing the cost of the golden apple snail in Asia. It can directly affect two aquatic crops: taro (Colocasia esculenta) and rice (Oryza sativa), but probably others. Biology of the golden apple snail, Pomacea canaliculata (Lamarck, 1822) with emphasis on responses to certain environmental conditions in Sabah, Malaysia. They tend to have more prominent shell spires, though this character is variable in all three species, and the sutures between their whorls are not deeply channellized. by Joshi, R. C.\Sebastian, L. S.]. At 20 and 25°C and >95% RH these small snails survived the duration of the experiment (308 days). Zootaxa, 3940:1-92. http://www.mapress.com/zootaxa/2015/f/z03940p092f.pdf, Cowie RH, Hayes KA, 2012. 100 of the world's worst invasive alien species: a selection from the global invasive species database. Produced with support from the Australian Centre for International Agricultural Research under project HORT/2016/185: Responding to emerging pest and disease threats to horticulture in the Pacific islands, implemented by the University of Queensland and the Secretariat of the Pacific. Larger snails survived longer than smaller snails. It has been reported from estuaries (EFSA Panel on Plant Health, 2012) but its salinity tolerance probably prevents its extensive penetration into such brackish habitats (Ramakrishnan, 2007), although eggs remain viable when exposed to periodic inundations typical of a tidal regime and modest, albeit reduced, growth and survival occurs at moderate salinities (5 and 10‰) (Martin and Valentine, 2014). 2012 : 730 ): NHMUK 1854.12. The study in Thailand, however, may well have been on P. maculata, as the size of the snails reported in this study exceeded the maximum dimension given by Hayes et al. P. maculata occurs in shallow parts of slow-moving bodies of fresh water, close to riverbanks, at the edges of lakes and in ponds, in wetlands and irrigated wetland croplands and in drainage/irrigation ditches. Pomacea maculata; the increasing thickness of opercula as the snail increases in age and size. The snail is a hazard to human health. In general, Pomacea were not well liked as a food in Asia and markets did not develop (e.g. Their results imply that P. maculata range expansion could have a direct negative impact on P. paludosa populations, especially considering that juvenile survival may be particularly important for increasing population densities (Burlakova et al., 2009). Pomacea maculata; newly collected, medium-sized specimens, laying pink egg clutches. 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. Differences in shell morphology are most notable in newly hatched juveniles. Snail Busters apple snail trap as delivered for deployment to control apple snails. The mobile application is available from the Google Play Store and Apple iTunes. However, it has been extremely confused because of the gross morphological similarity within major ampullariid groups accompanied by considerable intra-specific variation. Very few educational efforts exist to prevent this common occurrence from happening again and again (Martin et al., 2012). Thus, the natural range of P. canaliculata was formerly thought to extend from temperate Argentina into northern Amazonia (Cazzaniga, 2002), the species having been confused with P. maculata. Plant Quarantine Pest Evaluation Data Sheets., USA: US Department of Agriculture, Animal and Plant Health Inspection Service. Feeding and growth of native, invasive and non-invasive alien apple snails (Ampullariidae) in the United States: invasives eat more and grow more. P. maculata probably accounts for some proportion of the total amount; however, it remains difficult to determine whether or not past studies were based on P. maculata, P. canaliculata or a mixture of the two species. 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. In: Global advances in ecology and management of golden apple snails [ed. In: Global advances in ecology and management of golden apple snails [ed. Snails survived by filling their shells with air and floating away from the pesticide application. In fact, no published study has suggested that P. maculata consumes substantial quantities of E. crassipes quickly. Wikipedia. These intentional introductions eventually gave way to accidental introductions as these aquaculture projects failed, the markets having been over-estimated. EPPO Global database. © Copyright 2020 CAB International. The name has been given to several Pomacea species, due to confused identification. Hatchlings are likely to rely on detritus and algal-based resources for food, although they also readily consume lettuce in the laboratory. (2012) described a case study of repeated copper sulfate application to Langan Pond and Three Mile Creek in Mobile, Alabama. Loss of native snails in many places is considered a direct result from apple snail introductions and/or an indirect result from pesticide use to control them. by Joshi, R. C.\Sebastian, L. S.]. Risks of species introduced for biological control. It may also feed on some submerged or freely floating plants that have tough physical structures or chemical defence compounds. PhD Dissertation. Clutches should be physically destroyed by crushing. Specifically, P. maculata also quickly consumed S. latifolia after eliminating the Utricularia. In a similar study to that of Burlakova et al. P. canaliculata and P. maculata. However, no studies have examined the survivorship or viability of any possible hybrids between the two species. Furthermore, few studies have investigated the indirect impacts of the pesticide on ecosystems. Due to the confusion in species identification, the history of introduction of P. maculata remains somewhat uncertain as does its invasiveness and pest potential. (2008), the difficulty of distinguishing P. canaliculata from P. maculata meant that not only were their true ranges in South America not understood but also that the correct identities of ampullariids in Asia and other locations to which they have been introduced were not known. With the global need to find alternate protein sources, the culinary industries of various countries might explore further the use of apple snails as a local delicacy or ethnic cuisine. Pomacea maculata; mating pair. Los Banos, Philippines: Philippine Rice Research Institute (PhilRice), 243-254, Dillon RT, 2006. by Joshi, R. C.\Sebastian, L. S.]. The majority of references identify Argentina as the original source of the introduced Pomacea (e.g. With some exceptions (e.g. 14 (4), 701-712. http://www.blackwell-synergy.com/loi/ddi DOI:10.1111/j.1472-4642.2008.00483.x. The operculum of P. maculata is also much thicker and more inflexible than that of P. canaliculata, creating a much less effective seal. Furthermore, the recent name changes (Hayes et al., 2012) complicate matters because permit restrictions may lag behind changes in scientific terminology. Ampullarium, insularus, insularis). Impact of invasive apple snails on the functioning and services of natural and managed wetlands. Nonetheless, the development of the two types of tissue varies with maturity and they may appear undifferentiated in younger individuals. In the native range of P. maculata in South America the extent of the parasite’s distribution remains uncertain (Thiengo et al., 2013). Although usually confined initially to aquaculture facilities, the snails either escape or are deliberately released into agricultural or natural wetlands. Applied Entomology and Zoology. (2008), Matsukura et al. Egg clutches on the other hand can be easily observed. Pomacea maculata differs substantially from Pomacea diffusa, the scientific name of the so-called ‘spike-topped’ apple snail found in the aquarium trade (Rawlings et al., 2007). maculata’. Radular morphology of Pomacea maculata (a & c) and Pomacea canaliculata (b & d). However, experimental evidence (Ramakrishnan, 2007) indicates that P. maculata can survive long periods (i.e. Non indigenous land and freshwater gastropods in Israel. These populations probably became mixed through either deliberate human-mediated introductions or via natural spread of one species to localities already invaded by the other. by Simberloff, D. \Schmitz, D. C. \Brown, T. C.]. Plos One, 8(5):10.1371/journal.pone.0063782, Dreon MS, Ituarte S, Heras H, 2010. Out of South America: multiple origins of non-native apple snails in Asia. In: Biological Conservation, 78(1/2) [ed. Among the most interesting of the molluscs are the snails. 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. The golden apple snail Pomacea canaliculata in Asian rice farming systems: present impact and future threat. Curated hierarchies for Pomacea maculata (Perry 1810). In contrast, ephemeral agricultural habitats contained extremely high densities (>130 snails per square meter), and furthermore, snail size and numbers varied through time, both peaking in autumn. Golden apple snail, Pomacea species (Thailand). Applesnails, Pomacea maculata, cluster of pink snail eggs on branch, swampy area of Paynes Prairie Preserve State Park. Tolerance of embryos and hatchlings of the invasive apple snail Pomacea maculata to estuarine conditions. Data source for updated system data added to species habitat list. Pomacea maculata is a species of large, globular, freshwater snail native to tropical and sub-tropical South America. Consequently, species boundaries have been very difficult to assess based solely on conchology. A few studies have been done in Asia on the use of fish to control P. canaliculata (see the Invasive Species Compendium datasheet for P. canaliculata). In contrast, the bright pink egg clutches cannot be missed in the landscape. As for any invasive species, early detection, prompt eradication and strong regulation of transport are the best defenses against introduction and establishment of P. maculata as an alien invasive species. It is possible that snails (especially small juveniles or hatchlings) or their eggs may also be transported on wetland plants or propagules used for outplanting, as suggested for P. canaliculata (Cowie, 2002; Levin et al., 2006). by Joshi, R. C. \Sebastia, L. S.]. Key = Green: apical sheath gland; Orange: basal penis sheath gland; Blue: penis bulb and penis pouch; Purple: prostate. The eggs are spherical, calcareous, deep pink-red to lighter orange-pink, becoming paler as the calcium hardens, and eventually whitish pink just before hatching. by Joshi, R. C.\Sebastian, L. S.]. (2010) noted that P. maculata in Texas laid a disproportional number of clutches on riparian vegetation, specifically taro (Colocasia esculenta). Thailand), the dates given by Mochida (1991) for introduction of Pomacea to particular countries can therefore be taken as the earliest date that P. maculata might have been introduced to those countries. As one example, in Florida, the St. John’s Water Management District (SJFMD) in cooperation with the Florida Fish and Wildlife Conservation Commission (FWCC) applied copper sulfate to Newnans’ Lake in 2007.

However, the algae-eating ‘spike-topped’ apple snail, Pomacea diffusa (formerly identified as the different species Pomacea bridgesii) is not perceived as a threat to agriculture and so P. diffusa remains freely available in the aquarium trade. Active, short term dispersal does not necessarily translate into long term, long distance dispersal. P. maculata has separate sexes with female size typically exceeding male size. This requires the user to check the trap often (i.e. Adult P. maculata can reach up to 165 mm in shell height and weigh over 200g (Kyle et al., 2009; Hayes et al., 2012). Patients suffer extreme ill effects and may die as a result of infection (Cowie, 2013b). http://www.aphis.usda.gov/wps/portal/aphis/ourfocus/planthealth, USGS, 2013. (2013) found preliminary genetic evidence of hybrid individuals. They also inhabit nearly all ecosystems. Fecundity of the exotic apple snail, Pomacea insularum. In the same year (1810), a few months after Perry's publication, Montfort introduced the generic name Ampullarius as an unjustified emendation of Ampullaria. They easily survive brief periods out of water using their lung rather than their gill, for instance during egg laying.
