Effect of two insecticides on hickory shuckworm (Lepidoptera: Tortricidae) and predators of pecan pests
Southwestern Entomologist 34 (3), 227-238
Abstract: Tebufenozide and chlorpyrifos were evaluated in the laboratory and field to find an insecticide more compatible with integrated pest management for pecan, Carya illinoinensis (Wangenh.) K. Koch. Different developmental stages (eggs, larvae, and/or adults) of six predators of pecan aphids were exposed to the insecticides. Control of hickory shuckworm, Cydia caryana (Fitch), by the insecticides and selectivity to native predators of pecan aphids were also tested in commercial orchards. Tebufenozide had no significant adverse effect on coccinellids, but killed eggs of the lacewings Chrysoperla rufilabris (Burmeister) and adults of Chrysoperla carnea Stephens. Chlorpyrifos was very toxic to all stages of crysopids, exhibiting ovicidal activity on multicolored Asian lady beetle, Harmonia axyridis (Pallas). Both insecticides were effective in controlling hickory shuckworm in the field. Tebufenozide applied in orchards was innocuous, while chlorpyrifos killed beneficial insects. Chlorpyrifos significantly reduced the number of blackmargined aphids, Monellia caryella (Fitch). Tebufenozide because of its effectiveness in controlling hickory shuckworm and less detrimental impact on beneficial fauna is recommended rather than chlorpyrifos for integrated pest management. Also, tebufenozide is less toxic to human health and the environment.
