Conteúdo: | Two laboratory tests were conducted aiming to evaluate the survival and length of instars of Nezara viridula nymphs, feeding on susceptible and resistant soybean genotypes, represented by commercial varieties from Brazil and USA, and breeding lines from the Brazilian breesing programme. Immediately after the oviposition, the insects were placed in Petri dishes containing fresh pods of the tested genotypes. The pods were changed each other day, during the whole experiment. Insects were daily observed to record survival and length of the instars. High mortality of first instar nymphs was observed when insects fed on the line BRT92-10644 or the cultivars IAC-17 and IAC-100. Stink bug nymphs fed on BRT92-10868, BRT92-10644 or Crocket, in both tests and Lamar in one of tests, had nymphal stage extended when compared to the control. Extended cycle and high mortality of bugs indicate that BRT92-10644 is not an adequate food source for stink bugs.
