Abstract

Molluscicidal effects of the tested pesticides namely; bindiocarb, sumithion
and machet against adult stage of three land snail species ; Monacha obslructa ,
Theba pisana and Eobania vermicu/ata were studied under laboratory conditions .Two
techniques,( i .e.contact and bail) were used f or exposure the snailS to pesticides .
Bindiocarb proved to be the most toxic one for the three tested snails. The lCso's
were 1.12 s 2.26 ; 1.77 & 2.53 and 1.87 & 3.17 % ; while machet gave the lowest
efficacy ( LC50'S 3.19 s 3.48 ; 3.69 s 3.64 and 4.08 & 4.18 % ) for the three tested
snail species as contact and baitlechnique , respectively. The difference in toxicity of
tested pesticides against snails could be explained on the basis 01 their chemical
structure . The relationship between the chemical structure and the toxicity M.
obstructa was comparatively sensitive for the three lested compounds than T. pisana ;
while E. vermicuiata exhibited a high tolerance against the three tested compounds.
On the other hand, contact technique was more effective.
