Comparative food utilization of coffee bean weevil larvae on a new freeze-dried diet and green coffee beans
A meridic diet for culturing the coffe bean weevil, Araecerus fasciculatus was formulated and freeze-dried into pellets. When exposed to an atmosphere of 80 +- 5r.h. the diet reached a moisture equilibrium that invoked oviposition and was satisfactory for growth and development of the insect. Larvae ingested larger amounts of the freeze-dried diet than of the natural food, green coffee beans, reaching equivalent weight and pupation in 31.8 +- 0.4 days on the diet as compared to 46.8 +- 0.8 days on the coffee beans. Approximate digestibilities of the two foods were not significantly different. However, the coffee beans were converted more efficiently to body mass than was the diet. Faeces of larvae on the diet contained more uric acid than those of larvae on coffee beans. Continuous culture and mass rearing of A. fasciculatus on the diet is possible
