Toxicity and Sublethal Effects of Essential Oil on Behavioral and Physiological Responses of Populations.

This study aimed to evaluate the toxicity of essential oil (PHEO) against 11 Brazilian populations of (Coleoptera: Curculionidae). The effects of sublethal doses of PHEO on the behavior (walking and flying), respiration, and population growth () of the insect populations were investigated. PHEO toxicity was determined through concentration-mortality bioassays, with mortality curves established using increasing PHEO concentrations ranging from 140.
