Augmentative releases of Catolaccus grandis (Burks), an exotic parasite of boll weevil, Anthonomus grandis grandis Boheman, were successfully integrated with standard Integrated Pest Management (IPM) and agronomic practices employed in the "short-season" cotton production system of the Lower Rio Grande Valley. Two potentially-disruptive practices (preemptive early-season insecticidal applications and the use of mechanical cultivation) were shown to be compatible with augmentative parasite releases if used judiciously and timed properly. Release rates of 500 to 1,000 female parasites per acre per week produced an acceptable degree of control (means of 66.3-79.5% apparent parasitism of third-stage weevil larvae and pupae) and facilitated the development of acceptable yields in release sites relative to adjacent fields subjected to as many as 14 insecticide applications (658-1,322 and 864-1,290 lbs lint/ac, respectively). The potential role of parasites such as C. grandis for suppression of boll weevil in "short-season" cotton production systems is discussed.
