Mechanisms of resistance in soybean (Glycine max [L.] Merrill) genotype PI171444 to the southern green stink bug, Nezara viridula (L.) (Hemiptera: Pentatomidae)
Environmental Entomology 13 (5), 1208-1215
Abstract: Possible mechanisms of resistance to N. viridula in soybeans (Glycine max [L.] Merrill), genotype P1171444, were examined. Antibiosis was evaluated through fifth stadium and whole-life rearing of nymphs on pods of field and greenhouse-grown plants. Newly emerged adults reared on P1171444 weighed less than those reared on 'Davis,' although there were no differences in the length of developmental time or mortality. There were no differences in the number of feeding sheaths deposited by adults in greenhouse nochoice and laboratory choice tests with pods. However, females consistently chose 'Davis' over P1171444 in laboratory choice tests with leaves and pods, suggesting nonpreference for P1171444. Nonpreference, antibiosis, and temporal separation are discussed as mechanisms contributing to the high resistance to stink bugs previously reported for P1171444 in the field.
