Description: In a preliminary study, two chemosterilants-tepa and hempa-were tested for their effects on the fertility of adult bark beetles (Ips confusus [LeConte). Hempa was Ineffective. Tepa proved 97 percent effective in reducing egg hatch, when applied at 10 µg./10 mg. body weight to both parents. The possibility of using a chemosterilant and the male sex pheromone jointly to attract and sexually sterilize insect populations in the field shows promise.
