Abstract
Panel traps baited with prionic acid pheromone lures were effective in monitoring adult male Prionus imbricornis (L.) and Prionus laticolis (Drury) (Coleoptera: Cerambycidae) beetles in commercial pecan, Carya illinoensis (Wangenheim) K.Koch, orchards in southern Georgia and northern Florida. Pheromone lures with 30 mg of prionic acid trapped beetles for 6 to 7 weeks in the field. A soil surface application of chlorpyrifos solution at a concentration 1.25 ml/L and 0.6 L/m2 had an efficacy of 92% against adult male beetles and persisted for 3 weeks. A matrix of lures made from 30-mg prionic acid–treated Isomate CP plastic-coated wire at 250 lures/ha prevented pheromone-baited panel traps from attracting male P. imbricornis beetles. One deployment of the matrix of lures prevented sentinel traps from collecting beetles for the entire 6-week flight period. The addition of LED lights to the pheromone-baited panel trap significantly increased the number of P. imbricornis male beetles trapped per trap per night by 8%.
