| Abstract: | Possible mechanisms of resistance to Nezara viridula in soyabeans, genotype PI171444, were examined in Louisiana. Antibiosis was evaluated through 5th instar and whole-life rearing of nymphs on pods of field and greenhouse-grown plants. Newly emerged adults reared on PI171444 weighed less than those reared on the Davis genotype, 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 no-choice and laboratory choice tests with pods. However, females consistently chose Davis over PI171444 in laboratory choice tests with leaves and pods, suggesting non-preference for PI171444. Non-preference, antibiosis and temporal separation are discussed as mechanisms contributing to the high resistance to N. viridula previously reported for PI171444 in the field. |
