Fertility and Life Expectancy of a Predatory Stinkbug to Sublethal Doses of a Pyrethroid

Podisus distinctus (Heteroptera: Pentatomidae) is an important predator used in biological control of eucalypt defoliating caterpillars, exposed the insecticides. Lower doses of permethrin not affect the values of generation time ( T ), time necessary to double the population in number of individual...

Description
Summary:Podisus distinctus (Heteroptera: Pentatomidae) is an important predator used in biological control of eucalypt defoliating caterpillars, exposed the insecticides. Lower doses of permethrin not affect the values of generation time ( T ), time necessary to double the population in number of individuals ( DT ) and intrinsic rate of population increase ( r m ). Moreover, females of P. distinctus derived from nymphs treated with lower doses of permethrin were more fertile, triggering the effect hormetic in net reproductive rates ( Ro ). Results showed that low permethrin doses can be used alongside the predatory stinkbug in Integrated Pest Management programs.
