Graphic AbstractĪltschul SF, Madden TL, Schäffer AA, Zhang J, Zhang Z, Miller W, Lipman DJ (1997) Gapped BLAST and PSI-BLAST: a new generation of protein database search programs. This novel tool would be valuable in integrative taxonomic studies to distinguish these two lineages of Pomacea and contribute to our understanding of Pomacea diversity.

Eggs are oviposited in conspicuous reddish masses above the waterline, allowing rapid detection and easy collection of samples in the field. The method was validated in the field by analysing seven populations from Asia (non-native) and South America (native) that had been genetically identified and in which PQ differed consistently between the two species. Results can be obtained in less than 24 h. Then, the ratio between two wavelengths (PQ) of the absorbance spectra is calculated. The egg perivitelline fluid is analyzed via conventional agarose gel electrophoresis and the naturally-colored egg carotenoproteins are extracted, without the need for staining, and analyzed spectrophotometrically. Here we report a new taxonomic character based on the spectroscopic characteristics of their pigmented perivitellins (egg proteins) and a fast and simple method for measuring it. Thus, additional work is needed to clarify species boundaries in this group of Pomacea. Despite having different invasive potential, they have systematically been misidentified because of their morphological plasticity with highly variable shells, which hampers efforts to manage their spread and impact. They are expanding their ranges in Asia, Europe and North America, damaging crops, wetland ecosystems and endangering human health.

maculata are freshwater apple snails considered two of the most invasive alien species worldwide. This study provides a society implication for paddy farmers, in which the creation of this tool is effective and important to drive the farmers to better productivity with the eradication of GAS eggs.Pomacea canaliculata and P. More particularly, the invention relates to a tool that adapts hand-picking method in controlling and eradicating the eggs of these pests. This study aims to design the biological tool or prototype to eradicate this major pest. Nevertheless, GAS eradication has become a laborious and expensive task. Numerous research have shown that GAS can be managed at various stages of cultivation by combining chemical, mechanical, and biological steps. Thus, GAS is now a major pest in the cultivation of rice. However, its physiological adaptability and capacity to travel a long distance within a water system has become an invader of new habitats. Several potential benefits of Golden Apple Snail, or GAS have been reported, including its use as a source of food, use in the trade of aquariums, biological control of plants, as a source of protein for fish, ducks and crocodiles, and as a liquid biofertilizer.
