Abstract
A rearing method for the production of successive generations of Anomala cuprea HOPE was tested in the laboratory. The third instar larvae were exposed to low temperatures (10 and 20°C), for four different periods of time (10, 20, 30 and 40 days). The duration of the developmental period from the egg stage to adult emergence was considerably shortened by the treatment at 20°C, and the shortest duration was observed when the larvae were exposed to 20°C for 30 days on the 30th day after the third instar. The mean number of days required for the completion of their life cycle was 181 days. These findings show that the adult was able to repeat a half-year cycle. Therefore, various artificial diets for rearing adults were studied in this experiment. The adults were reared on two artificial diets (A and B) containing dried powder of young leaves of Podocarpus macrophylla D. DON. With regard to the adult longevity, egg number and hatchability, the artificial diet A was superior to the other diets.
