Effects of susceptible and resistant soybeans, Glycine max (L.) Merrill, at different phenological stages on development, leaf consumption, and oviposition of Anticarsia gemmatalis Hubner were investigated under field and laboratory conditions. Populations of small and large A. gemmatalis larvae and level of defoliation were significantly higher on untreated plots of Cobb than on D75-10230 soybeans. Populations peaked 5 days earlier in plots of the susceptible variety. Slower defoliation observed on untreated plots of D75-10230 suggests the presence of some feeding deterrent. Plots of these two soybean fenotypes sprayed at economic threshold level received the same number of insecticide treatments; however, under less severe insect pressure, D75-10230 may require fewer treatments. The "yield potential" of the susceptible soybean was significantly higher than of the resistant genotype. Fungicide application reduced the effectiveness of Nomuraea rileyi (Farlow) Samson, and consequently the soybean yield, since sprayed plots showed the lowest yields. In the laboratory total leaf area consumption of A. gemmatalis declined on more advanced plant phenological stages, while total dry weight consumption increased. Total leaf area consumed was significantly smaller only for cohorts which fed on the resistant genotype at beginning of pod set stage. This suggests that resistance mechanisms may vary according to plant phenological stage, and in this present study the resistance factor was apparently more effective in the more advanced plant stage. The larval stage was significantly longer when feeding on D75-10230, and two additional days of feeding were required for the cohorts which were D75-10230 in the late vegetative stage to consume leaf area comparable to the cohorts which were fed Cobb. Leaf area consumption was always significantly higher on Cobb than on D75-10230 when comparisons were made on a per day basis. Results from dry weight consumption were not consistently higher for cohorts feeding on the susceptible genotype. The antibiosis effect of D75-10230 soybeans was not strong enough to cause extensive larval mortality; however, its expression results in slower feeding rates, lower larval weight, and lengthened larval development. Mean fecundity of all cohorts which were fed foliage from Cobb and D75-10230 at the beginning of the pod set stage was significantly higher than those cohorts which were fed foliage from late vegetative stage plants. Results suggest that D75-10230 does not reduce the fecundity of A. gemmatalis. MenosEffects of susceptible and resistant soybeans, Glycine max (L.)
