<i>Euborellia annulipes</i> Mortality and Predation on <i>Diatraea saccharalis</i> Eggs after Application of Chemical and Biological Insecticides

Chemical and biological insecticides have been frequently used in sugarcane fields to control insects-pests, including the borer, Diatraea saccharalis. Among products used, those based on chlorantraniliprole Metarhizium anisopliae entomopathogenic fungus, stand out. Euborellia annulipes is an insect of order Dermaptera considered a potential predator borer eggs. This study aimed evaluate direct indirect effects bioinsecticide M. (Metarril®) chemical insecticide (Altacor®) mortality E. nymphs adults, predation feeding preference earwigs eggs treated with formulated products. Predator was evaluated for seven days after treatment, while effect analyzed by tests without choice, using prey The tested were selective predator, causing ≤ 2% not affecting predation. application favored food fourth-instar nymphs, males, females predator. Our results show that Metarril® Altacor® can be D. saccharalis when associated annulipes.
