Insecticides may cause mortality and deleterious effects on predatory stinkbugs.For this reason,the effect of five concentrations of permethrin applied on third instar nymphs of Supputius cincticeps (Stål) (Heteroptera:Pentatomidae) was investigated on ovary activation in this predator.The nymphs received topical application of permethrin in the following concentrations (mg a.i./ml):10(-7),10(-6),10(-5),10(-4),and 10(-3).Ovary lengths and oocyte numbers were quantified following first egg mass.Ovary length of S.cincticeps varied from 5.7 mm with 10(-4) mg a.i./ml,to 6.4 mm with 10(-7) mg a.i./ml,with similar values for the other permethrin concentrations and for the control.The number of oocytes per female varied from 13.5 with 10(-3) mg a.i./ml,to 29.2 for the control,with significant differences.The number of oocytes per female of nymphs exposed to a permethrin concentration of 10(-5) mg a.i./ml was similar to that of the control.However,the lower number of oocytes per female from nymphs exposed to other concentrations of permethrin suggests that this insecticide may affect the reproductive capacity of this predator.The results obtained are discussed in relation to tolerance of Heteroptera predators to insecticides and possible hormesis occurrence.
