2. Antixenosis to Chrysodeixis includens (Lepidoptera: Noctuidae) among soybean genotypes
ABSTRACT The soybean looper Chrysodeixis includens is one of the main defoliating pests of soybean cultures in Brazil. This work aimed to evaluate the effect of offering different soybean genotypes to this insect to verify the occurrence of antixenosis. In a greenhouse, assays were carried out to determine the attractiveness of C. includens adults given free
