A new preparative form of acitinin was developed on the basis of biologically active substance derived from the biomass of an actinomycete. Two fractions of this preparation were studied for the antifeeding effect as well as the intestinal, larvicidal, and ovicidal toxicity for the colorado beetle as compared to the initial form of actinin and insecticides. The effect of light temperatures upon biologic activity of actinin's lipid fractions has been investigated. It has been shown that the lipid fraction extracted from lyophilized powder of actinomycete possessed antifeeding and pesticidal activity against colorado beetle. The contact and ovicidae toxicity of actinin (10% e.c.) was by many times higher as compared to chlorophos (80% techn.) and phosalone (35% e.c.). The preparation can be easily applied, its solutions are homogenous
