Stink bugs are important soybean pest and efforts have been made to obtain cultivars with, at lest, moderate level of resistance. Experiments were carried out to evaluate the effect of soybean genotypes ('BR-16', 'IAC-100', PI 227687, PI229358, PI 274454) on Nezara viridula survival, initial weight, adult fresh weight, growth, weight gain and lipid accumulation. When fed on PI 227687 and 'BR16' (control) pods, survivorship of N. viridula nymphs were 33.7% and 72.5%. Nymphs placed in Petri dishes containing PI 274454 and 'BR16' pods, at the first day of second instar, weighed 1.06 mg and 1.04 mg, being heavier than those with PI 227687 (0.74 mg) and 'IAC 100' (0.66 mg). Adult fresh weights were 146.85 mg when insect fed on 'BR 16', 127.04 mg on PI 227687 and 125.50 mg on 'IAC 100'. The last two genotypes negatively affected stink bugs growth (adult fresh weight adjusted for development time, by ANCOVA) and gain of weight (adult fresh weight adjusted for nymph initial weight, by ANCOVA); they also accumulated less lipids in their bodies. Consequently, PI 227687 and 'IAC-100' are inadequate food source to N. viridula, being a promising alternative to be used in soybean breeding programs as source of resistance to stink bug. |
