Abstract: In order to explore the feasibility of breeding Arma chinensis with Tenebrio molitor as food, Arma chinensis’s developmental duration, mortality, adult weight and egg production by feeding on Tenebrio molitor pupae, Mythimna separata pupae and Mythimna separata nymph in the laboratory were measured and compared. The results showed that Arma chinensis feeding on Tenebrio molitor pupae could normally complete generation development, and there was no significant difference in body weight of adult Arma chinensis feeding on three kinds of food. Arma chinensis feeding on Tenebrio molitor： The nymph duration was 27.97 d, which was significantly lower than 25.30 d in the pupa group and 31.27 d in the larva group of Mythimna separata; The mortality rate of nymph was 26.67%, which was significantly lower than 33.33% and 83.33% of pupae and larvae feeding on Mythimna separata; The average spawning amount of single females in the generation was 266.67, which was significantly different from 413.00 in the pupa group of Mythimna separata and not significantly different from 292.3 in the larvae group of Mythimna separata.
