Abstract: Rearing of Anomala corpulenta Motschulsky were conducted in the laboratory condition and the main influencing factors were evaluted. The results showed that it took 274.3 days for the beetle to complete a life cycle in the laboratory conditions. The duration of the 3rd instar reared in the laboratory was 101.8 days shorter than that in fields. The growth of larvae was influenced by such factors as soil humidity, food and pathogens. The average survival rate of eggs was 86.0% while those of the 1st instar, 2nd instar and 3rd instar larvae were 82.0%, 76.0% and 60.0%, respectively. The mortalities of the 10 day-old and 15 day-old larvae reared in the soil with potato as food for 14 days were 8.8％±1.6% and 4.0％±1.6% respectively, significantly lower than those for the newly hatched larvae and 5 day-old larvae. This result suggested that the larval age of 10－15 day-old was the optimum stage for bioassay of Bt. The larvae grew normally in the UV-irradiated loam and sandy loam soil, with their mortalities lower than that in the untreated and sterilized loam and sandy loam soil.
