Abstract

Methomyl is a systemic-contact carbamate insecticide acetylcholinesterase inhibitor. Lantana camara is a plant that presents antimicrobial, insecticidal, repellent and nematicide properties. The aim of this study was to evaluate the acute and chronic toxicity of methomyl and L. camara on five biological controls of agricultural pests of Peru. Toxicity tests for Cereaochrysa cincta, Chrysoperla asoralis, Trichogramma pretiosum, Trichogramma pintoi and Trichogrammatoidea bactrae used methomyl and L. camara with five concentrations plus control. C. asoralis relative to first instar larval mortality and no hatching of eggs were more sensitive to methomyl in relation to C. cincta. Instead C. cincta was slightly more sensitive to C. asoralis relating to lantana at first instar larval mortality and to non-egg hatching. The sequence descending of methomyl toxicity in adults and not emerged was: T. pretiosum > T. bactrae > T. pintoi. Regarding these three parasitoids, the aqueous extract of lantana had no significant effect on adult survival and only produced a significant decrease in the emergence of T. pintoi and T. bactrae. Methomyl showed harmful effects on the five species of beneficial fauna compared with lantana, which proved to be harmless.
