Combined use of Chrysoperla rufilabris (Neuroptera: Chrysopidae) and Cry3Aa for improved control of Leptinotarsa decemlineata (Coleoptera: Chrysomelidae).

ABSTRACT: The Colorado potato beetle (CPB, Leptinotarsa decemlineata (Say)) is the most important defoliator of solanaceous crops. Control of this pest is hindered by its ability to develop resistance to insecticides, including insecticidal proteins from Bacillus thuringiensis (Bt) Berliner. Therefore, it is important to find alternative tools that may be combined into an integrated pest management approach for CPB control. In this study, we evaluated the efficiency of the combined use of the Cry3Aa protein from Bt and Chrysoperla rufilabris (Burmeister) in controlling CPB. Control of CPB larval second instar at different densities by 3 larval instars of the predator was tested in potato leaves treated with an LC50 concentration of the Cry3Aa protein. Potato leaf damage was evaluated in experiments
