[Development and reproduction of the predator Podisus distinctus (Stal) (Heteroptera: Pentatomidae) exposed to sublethal doses of permethrin]
Neotropical Entomology 31 (3), 445-448
Abstract: Development and reproduction were studied in the predator Podisus distinctus (Stal) subjected to sublethal doses of the insecticide permethrin under laboratory conditions. Third instar nymphs were subjected to topical application of permethrin at the doses of 0, 0.0172, 0.172, 1.72, 17.2 e 172 ppb. The only parameter statisticaly different was egg viability. This parameter had the gratest increase at the dose 0.172 ppb provinding evidence for the phenomenon of hormesis.
