Abstract:Field tests were conducted in 1978 and 1979 at Phoenix, Ariz., to evaluate two microbial insecticides, the nuclear polyhedrosis virus (AcMNPV) from the alfalfa looper, Autographa californica (Speyer), and the HD-l strain of Bacillus thuringiensis Berliner, for control of cotton leafperforators, Bucculatrix thurberiella Busck in cotton. Treating the cotton with a mixture of AcMNPV + B. thuringiensis + feeding adjuvant on a ca. 5-day schedule resulted in the greatest level of control, a 94% reduction in the number' of horseshoe stage larvae on leaves compared with untreated cotton. Reductions in the larval populations due to treatment with B. thuringiensis or B. thuringiensis + adjuvant ranged from 73 to 86% in the tests. Treating the cotton with the virus or virus + adjuvant resulted in reductions of larvae on leaves ranging from 36 to 55%, significantly less than treatments containing B. thuringiensis.
