Abstract:
[Objectives]  To investigate the feasibility and economic potential of the captive breeding of Protaetia brevitarsis Lewis in Xinjiang with a view to providing a scientific basis for this process and the utilization of livestock and poultry feces in this province. [Methods]  Cattle manure was used as a breeding and oviposition substrate for adults. P. brevitarsis pupae were reared both indoors and outdoors in the appropriate seasons and oviposition and emergence rates of indoor and outdoor colonies was compared. [Results]  Outdoor conditions were more conducive to adult emergence. In outdoor colonies, adults emerged 26 days after pupation, 4 days earlier than those kept indoors or in outdoor sheds. The peak period of emergence, during which the emergence rate reached 83%, began 30 days after pupation and lasted for 13 days. The post-emergence male-female sex ratio was close to 1∶1. Females emerged about 1 to 3 days earlier than males. There was not much difference in the oviposition rates of indoor and outdoor colonies, which were 109.80 eggs per female and 105.94 eggs per female, respectively. Both indoor and outdoor colonies entered the peak period of oviposition 30-35 days after emergence but oviposition declined sharply to almost zero by the 60th day. [Conclusion]  Large-scale artificial breeding of P. brevitarsis is feasible in Xinjiang. There is little difference in oviposition and adult emergence rates, or in the adult sex ratio, of colonies kept outdoors under natural conditions and those kept indoors under temperature controlled conditions.
