This research investigated the effects of neem oil on mortality, survival and malformations of
the non-target stink bug predator, Podisus nigrispinus. Neurotoxic and growth inhibitor
insecticides were used to compare the lethal and sublethal effects from neem oil on this
predator. Six concentrations of neem oil were topically applied onto nymphs and adults of
this predator. The mortality rates of third, fourth, and fifth instar nymphs increased with
increasing neem oil concentrations, suggesting low toxicity to P. nigrispinus nymphs …
