Multifunctional Trap Cropping System for Managing Stink Bugs in Cotton

The second year of a field study was conducted to determine the ability of a soybean trap crop to prevent dispersal of stink bugs from peanut into cotton in a peanut-cotton farmscape. Results demonstrate that three species of stink bugs, the southern green stink bug, the brown stink bug, and the green stink bug prefer soybean to cotton, and soybean can serve as a trap crop for these stink bugs. A soybean trap crop with stink bug capture traps containing lures with attractants for each of the three stink bugs species was more effective in trapping stink bugs than a soybean trap crop without the capture traps. Adding buckwheat to the trap crop resulted in higher stink bug egg parasitization in cotton.
