Abstract
Insect metamorphosis hormones of the polyhydroxylated sterol type are light sensitive and tend to lose their activity under the action of light, especially UV radiations. An insect controlling formulation is suggested herein, which contains, in addition to the insect metamorphosis hormones, photostabilizing substances such as benzotriazoles, substituted phenylglioxylic acids and salts thereof.
