Grandlure point sources located in prebloom soybean and whorl stage corn plots caused host-seeking boll weevils to immigrate into the plots and converge on the soybean and corn plants near the lures. Grandlure baits also significantly increased populations of boll weevils in nonsquaring and squaring regrowth cotton. The results of these experiments indicated a potential for using grandlure in combination with green crops other than early-planted cotton to form effective factitious crop systems for concentrating host-seeking boll weevils in early and late season.
