Abstract |
Molluscicidal effect of methomyl and two naturally occurring
compounds caffeine and theophylline in addition to an aqueous tea extract were evaluated against three land snail species ; 1lfonacha obstructa , Theba pisana and Eobania vermiculata under laboratory conditions. Three methods of bioassay were used, i.e., contact, leaf¬dipping and bait techniques. Results showed that theophylline was the most toxic compound for the three tested snail species followed by caffeine and methomyl while the aqueous tea extract had, the lowest effect. The land snail, E. vermiculata was comparatively less susceptible to the tested compounds than the other two species. Contact technique was the most effective method of application. The LC5a values of theophylline ; caffeine ; methomyl and tea extract when applied as contact were 0.36, 1.00, 1.30 and 8.22 ; 0.45, 1.16, 1.38 and 9.37 and 0.80, 1.42, 1.82 and 13.50 % for M. obstructa ; T. pisana and E. vermiculata, respectively.
