Abstract
Research over a 2-year period indicated that female pecan weevils, Curculio caryae Horn, tended to fly higher than males. Male pecan weevils were observed to be clumsy flyers and crawled to the pecan tree more often than females. Significant differences were noted among replicates, height flown by sexes, and distances from the tree where weevils were released. Pecan weevils do have definite habits in reaching the tree and this study seems to indicate that further investigations might be conducted to establish a method of control for the less mobile male weevils as well as for the higher flying females.
