Abstract

Biological investigation on the potato moth and its sensitivity to microbial pesticides.

Abstract

A study of the effects of major ecological factors on the development and physiology of the potato pest Phthorimaea operculella revealed its very high viability in southern areas of the Ukraine, USSR. Lepidocide [Bacillus thuringiensis subsp. kurstaki] and Bitoxibacillin [B. thuringiensis subsp. thuringiensis] were highly effective against the pest when applied at 10-25°C. Treatment of larvae with these preparations at 9-12°C showed that they were at least as active as Dipel [another formulation of B. thuringiensis subsp. kurstaki] and chemical insecticides.
