Apple snails are very sensitive to certain chemicals and compounds unfortunately some of these chemicals are used to treat fish diseases as fungi and parasites the snail has a genetic defect that alters the ovipositor groove, rendering it useless 2 something went wrong when the snail matured. The tropical and subtropical regions of the us have unique agricultural challenges opportunities for expansion of this sector are hampered by limited local resources and limited access to national resources regional support for agricultural research is critical to meet the increasing challenges and develop new opportunities for economic expansion in tropical island ecosystems.

Abstract : three species of apple snails (ampullariidae) have been introduced to hawaii in order to clarify their identities, determine their geographic origins, and evaluate their mtdna diversity in hawaii, we sequenced the coi and nd6 mtdna markers from 103 snails collected on the six main hawaiian islands. The snails that colonize an island may represent only a small fraction of the parent population’s genetic diversity if a rare mutant color form is mixed in among the new colony, a colony that was 1 in 1000 in the parent population, it may instantly be 1 in 10 in the new population. The ka/ks ratios also indicted that atp8 and nad2 had the potential to study the genetic diversity of apple snail populations within a species, which was coincident with genetic variation comparison of pcgs from the sequence similarity analyses. The apple snail could have massive consequences for biodiversity if it establishes in the freshwater wetlands of southern europe the risk is high for species such as amphibians and for some already threatened species, as well as for the diversity of native species and habitats.
