Molluskicidal activity of synthetic organic compounds (on the foot of Achatina fulica (Bowdich)

Terrestrial snails are economically destructive agricultural pests that cause great damage to vegetables and crops. The present study was performed to evaluate the toxicity of synthetic organic derivatives and subsequent histopathological alterations in the feet of Achatina fulica (Bowdich) after exposure to (E)-1-(4-bromophenyl)-3-(4-methylthiazole-5-yl) prop-2-en-1. Accordingly, the LC50 of the synthetic organic derivative was determined to be 1.4206±0.0981. These chemicals can easily penetrate the body of mollusks either by feeding or crawling on the surface, and the foot is the first point of contact. Histopathological and ultrastructural alterations were observed in the foot of Achatina fulica (Bowdich), as these organs play important roles in locomotion and mucus secretion. These alterations include degeneration of the normal structure of the cell by rupturing of the outer protecting membrane, and a large gap is created between the cells. The longitudinal muscle band is destroyed by increasing the space. These results are important from an economic point of view since these synthetic chemical compounds were used as molluskicdes for the control of Achatina fulica (Bowdich), which is an agricultural pest.
