摘要： Background: Chelisoches morio (Fabricius) (Dermaptera:Chelisochidae) is an important predator of Tirathaba rufivena (Walker) (Lepidoptera:Pyralidae). For better use of the natural enemy, a biological study on C.morio was conducted, particularly its developmental duration, survival, fecundity and sex ratio. And the feeding capacity of C.morio against T.rufivena was also studied under laboratory conditions. Results: The biological study on C.morio was revealed that female adults usually lay eggs in egg masses. The number of eggs per female averaged 140.17 eggs, and the incubation period was 7.50 days. The duration of nymphal development included four instars. The immature period was 83.95 days. The longevity of males and females was 58.60 and 93.55 days, respectively. The results from the study on the feeding capacity of C.morio using T.rufivena as food revealed that C.morio adults could consume 11.08, 7.87, 7.09, 6.82 and 5.89 first-to-fifth-instar T.rufivena larvae, respectively. Conclusions: C.morio showed a huge amount of predation on this pest at all larval stages, implying a significant potential for the use of C.morio in controlling T.rufivena.
