EFFECTS OF CARBOFURAN ON THE REPRODUCTIVE CAPACITY OF A FRESHWATER SNAIL, RADIX QUADRASI, UNDER LABORATORY CONDITIONS
AbstractTheÂ effectsÂ ofÂ 4Â sublethalÂ concentrationsÂ ofÂ carbofuranÂ (250,Â 500,Â 1000Â andÂ 2000Â ppm)Â onÂ the
reproductiveÂ capacity of R. quadrasi was determined. Results showedÂ thatÂ incubation periodÂ is delayedÂ and
inhibited by 1000 and 2000 ppm carbofuran but not by lower concentrations. The hatching period is longer in
treated snails and notÂ allÂ eggs hatchÂ inÂ the 1000 and 2000Â ppmÂ treatment. TheÂ percentageÂ of hatchingÂ is
inversely proportional to the carbofuran concentration.
OvipositionÂ wasÂ delayedÂ inÂ allÂ theÂ treatedÂ stagesÂ andÂ atÂ allÂ dosages.Â TheÂ higherÂ theÂ carbofuran
concentration,Â theÂ laterÂ the onset of oviposition. TheÂ reproductive periodÂ is shortened. Fecundity was
decreased in snails treated at EMB and SM. However, only the 2000 ppm carbofuran concentration showed an
adverse effect on the snails exposure at PSM.
