Abstract: The biological characteristics of Anisopteromalus calandrae, an ectoparasitoid of the Lasioderma serricorne (Fabricius), were investigated. Specifically, the developmental duration, longevity, feeding, parasitism behaviors and the effects of supplementary food on its development were measured. A. calandrae mainly parasitizes the old larvae and pupa of L. serricorne and overwinters as mature larvae or pupa in the host cocoon. At 25℃, 70% RH, photoperiod 16L:8D, the developmental durations of each stage were as follows:egg, 1.5 d; larva, 5.9 d; pupa, 9.9 d; pre-oviposition, 0.9 d; and adult, 15.1 d. It needs 18.2 d to complete a generation. Number of offspring per female A. calandrae was 29 to 82, averaging 54.75 in the laboratory. At 25℃ and fed 10% honey solution, the females lived 29.6 d and produced 76.1 offsprings. With short developmental period, high fecundity, and active search ability, A. calandrae is of a great potential for application as biocontrol agent.
