Induced pupation in Diaprepes abbreviatus Coleoptera Curculionidae



Induced pupation in Diaprepes abbreviatus Coleoptera Curculionidae



Florida Entomologist 70.1: 186-187



Diaprepes abbreviatus (L.), is a well known root weevil pest of sugarcane and citrus in the Caribbean Basin (Ballow 1912). The insect was first reported in the United States in 1964 (Woodruff 1964). Beavers (1983) developed an artificial diet and rearing procedures to establish laboratory colonies. Although the larvae grew rapidly on the diet the insects failed to pupate making it impossible to maintain the laboratory colony. Obviously, improved rearing procedures were needed to induce pupation. The authors observed that when 120 day larvae were removed from diet and placed in soil, the larvae formed pupal cells. To determine if pupation could be consistently induced by placing 120 day larvae in soil, they collected 280 diet-reared larvae.
