Pomacea insularumPomacea insularum commonly known as the orchard apple tree snail is a species of snail from the class Gastropoda. P. insularum be put in in warm wetlands habitats. They are capable of fast growth rates and breed galore(postnominal) offspring which increases their capability to quickly invade different ranges. recently this species has been spreading through southern United States and altering the environments in which they are found. The Pomacea insularum species in round in shape and is usually brown, black, and yellowish tan. P. insularum may reach 150 mm in length or the size of it of an apple. Their offspring are large egg masses that are a bright pink color. Pomacea insularum look very similar to Pomacea canaliculata making it unvoiced to properly identify.To better control the invasive species P. insularum it is alpha to understand the native range, invasive range, and related species. The known native range of this species is Argentina, Boliv ia, and Brazil. The Apple gather generally inhabit areas with slow moving or stagnant wet in lowland swamps, marshes, irrigation canals, streams, ponds, lakes and rivers. before long the species is invading in several areas of the humanity including several countries in the Asian and European continents. Another continent that P. insularum is found in is North America specifically the southern United States. States that hurt the species are Alabama, Florida, Georgia, Hawaii, Louisiana, and Texas. The first sighting of P. insularum in many of these states were in the 2000s while in Texas the first sited was 1989. A study done by Howell surveyed 393 sites in Texas and P. insularum was found in 53 of the sites. The snail was found in low densities in ponds and streams but in agr... ...dling age from two to quintet weeks resulted in significant reductions in snail damage.Management of the apple snails may gather in to target the entire genus of Pomacea since there are so m any invasive species of Pomacea in the United States.Forecasting the potential range of the Pomacea insularum is important for management of the species. Pomacea insularum lives in habits that are generally warm and composed of wetlands. Currently P. insularum is found in Alabama, Florida, Georgia, Hawaii, Louisiana, and Texas. These states all have areas that are warm and have wetlands. Under current climate conditions Pomacea insularum should not spread much farther through the United States. Along with the right climate P. insularum needs the amnionic fluid to be ph that is greater than 5.5. If the ph levels are lower than this progeny the snails survival and persistence declines.
