ABSTRACT
Chrysodeixis includens nucleopolyhedrovirus (ChinNPV Baculoviridae Alphabaculovirus) is an active ingredient of a biological-based insecticide (Chrysogen®) recommended against soybean looper (SBL), Chrysodeixis includens (Walker, [1858]), in soybean in Brazil. We investigated if SBL strains resistant to chemical insecticides are cross-resistant to the baculovirus ChinNPV. In droplet feeding bioassays, SBL strains resistant to lambda-cyhalothrin and teflubenzuron showed equivalent susceptibility to ChinNPV as heterozygous and susceptible strains, indicating no cross-resistance between ChinNPV and chemical insecticides in SBL. Therefore, the ChinNPV is a valuable new "mode-of-action" tool for SBL resistance management in Brazil.
