2013 Annual Report
2. Develop “push – pull” strategies for whitefly management that integrate plant-based pest repellents and natural enemy attractants.
3. Develop and refine control strategies for invasive species infesting non-traditional agricultural settings, in particular the Argentine cactus moth and Chinese tallow.
Push-pull strategies for the management of whiteflies will be developed. Certain plants and extracts from them will be tested in the field and lab to determine if they can repel whiteflies from target crops. Bioassays of other plants will be used to identify those that are good reservoirs for predators of whiteflies. Combinations of repellent plants and banker plants for predators will be studied to optimize push-pull strategies for whitefly management.
The sterile insect technique for management of invasive lepidopteran pests will be improved by development of bioassays that measure field performance of sterile moths. Lab bioassays will then be developed as proxy measures for field performance bioassays to gauge sterile insect performance. Existing pheromone trapping for monitoring cactus moth populations will be improved through calibrating captures with population size. Life table studies will be conducted in the cactus moth’s invaded range to identify stages most amenable for biological control. Additional biological control will be assessed by testing non target risks of Trichogramma pretiosum, a candidate for inundative releases. Population dynamic studies of Chinese tallow will be conducted to identify what types of biological control agents may have the greatest impact on the weed.
