Evaluation of Crude Euphorbiaceae Latex Against Black Slug, Filicaulis alte Ferussac

摘要

Feeding responses of black slug with yellow mid-dorsal streak, Filicaulis alte towards crude latex of different plants in wheat bran bait were observed in no-choice laboratory feeding tests. Their molluscicide effect for the control of the slug was inorder of Euphorbia splendens > Calotropis procera > Ficus bengalensis >Ficus elastica. The bait with 2% crude latex of E. splendens was most effective bait resulting in 36.7% slug mortality. C. procera latex (1.5%) in wheat bran bait caused 23.3% mortality while latex of F. bengalensis (1.5%) caused 20% slug mortality. All concentrations of F. elastica latex in bait neither acted as repellent nor as molluscicide.
