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.
