In a S-year field study conducted at Tallulah, Louisiana, postseason applications of insecticides, defoliants, and desiccants were all effective in reducing the number of diapausing boll weevils, Anthonomus grandis Boheman, entering ground trash. Defoliants and desicants appeared to cause the greatest reduction in the overwintering populations entering winter quarters. Weekly applications of methyl parathion and Guthion,® O,O-dimethyl S-( 4-oxo-l,2,3-benzotriazin-3-(4H)- ylmethyl) phosphorodithioate, during this period also reduced overwintering weevil populations to a low level. However, none of thc treatments completely eliminated the weevil populations in this series of experiments.
