Hypothenemus hampei Ferrari (Coleoptera: Curculionidae) is the main pest of coffee crops, and effective methods for pest management are needed urgently. Bioassays were conducted to assess the effects of the insecticide chlorantraniliprole on H. hampei adults. Toxicity, survivorship, larval production, respiration rate, and behavioral responses to six concentrations of chlorantraniliprole were evaluated. Chlorantraniliprole was toxic to H. hampei (LD50 = 0.49 mg mL−1 and LD90 = 1.21 mg mL−1). Survivorship was 98% in adults not exposed to chlorantraniliprole, decreasing to 52% in insects exposed to LD50 and 2% in insects treated with LD90. H. hampei showed reduced mobility on insecticide-treated surfaces. The insecticide promoted a decrease in the respiration rate of H. hampei for up to 3 h after exposure, altering behavioral responses and locomotor activity. Chlorantraniliprole was shown to have lethal and sublethal effects on H. hampei and, thus, can be used rotationally in integrated pest management programs to control of this pest in coffee crops and retard of insect resistance. •The control of coffee berry borer is carried out through conventional insecticides as endosulfan.•The insecticidal effects of the anthranilic diamide chlorantraniliprole were tested on H. hampei.•Chlorantraniliprole was toxic and reduced the survivorship of H. hampei at different lethal and sublethal concentrations.•Chlorantraniliprole exhibited significant activity to effectively disrupt the larval stage, altering the locomotor activity and reducing the respiration rate.•Lethal and sublethal effects of chlorantraniliprole in H. hampei can be an alternative control to endosulfan.
