Vacuum fumigation of Anthonomus grandis Boheman with hempa at 0.05–0.1 mm Hg at 21–23°C followed by a 4-day feeding period on diet containing 0.1% busulfan consistently sterilized both sexes. Pheromone production in males was not reduced, and 3-wk mortality was less than 40%. Young unfed weevils were very susceptible to hempa as well as to the lethal effects of high vacuum, but feeding for at least 1 h on 5% sucrose reduced the vacuum-induced mortality without affecting sterility. Chemical analysis of weevils soon after treatment showed residues of 498±355 g of hempa/weevil. Prompt rinsing with water removed most of the hempa from the weevils and greatly reduced the sterility caused by the hempa treatment.
