Detection probability and efficiency of infield and border traps for capturing overwintered boll weevils (Coleoptera: Curculionidae) at low population levels
Environmental Entomology 13 (1), 324-328
Abstract: The probability of detecting low overwintered populations of boll weevils, Anthonomus grandis grandis Boheman, with infield or border traps at the rate of 2.46/ha was determined. Even though all fields were infested with F₁ weevils, the parent population was not detected in 20% of the border-trapped fields; however, it was detected in all of the infield-trapped fields. The capture in traps away from overwintering habitat was greater than or equal to the capture in traps adjacent to overwintering habitat. The male boll weevils responded to the traps at a younger average age than the females.
