ABSTRACT
Cultural control strategies to manage the boll weevil, Anthonomus grandis grandis Boheman, can be implemented during each season of the year to enhance cotton production in the Texas Rolling Plains. In the spring, delayed, uniform planting between late May and early June forms the basis for cultural control of the boll weevil. During the summer, planting cotton on sloped beds, in an east-west row direction, can be used to increase exposure of fallen squares to high soil temperatures, which kill larvae inside the squares. In the fall, harvest-aid chemicals can be used to abscise squares and small bolls by late September. This reduces the proportion of the boll weevil population that enters diapause, and fewer boll weevils survive the winter. During the winter, cultural control strategies are designed to reduce winter survival. Complete elimination of winter habitat or modification of the habitat by destroying only the leaf litter where boll weevils overwinter are two options.
