Purpose The bionomics and breeding of Propomacrus davidi Deyrolle were studied.
Method We reported the discovery of the adults of P. davidi Deyrolle in their natural habitat, and the larvae were tested. The morphological characteristics and biological characteristics of eggs, larvae, pupa and adults were observed and recorded.
Results The third instar between 8.0 and 12.0 g (female 8.373±0.604, male 11.566±0.411); larvae hatched between 15 and 25 days; larvae duration between 240 and 283 days in male and 238 to 267 days in female; the pupal phase between 24 and 30 days; 12 to 17 days emergence.
Conclusion P. davidi Deyrolle was the first artificial breeding, the morphological characteristics and biological characteristics of each insect state were described, and a method for artificial breeding was initially proposed.
