Insect Repellents


Insect Repellents

 

(in Russian, antifidingi), chemical means of repelling insects from the plants on which they feed.

A comparatively small number of substances possessing these properties are known—for example, triphenyl tin oxide [(C6H5)3Sn]2O and triphenyl tin acetate (C6H5)3Sn(CH3COO). When plants are treated with even a small quantity of these substances, insects (such as the Colorado potato beetle and some types of the family Noctuidae) found on these plants are killed. This form of repellent has not received wide practical application at the present time.
