Abstract: In the laboratory, some physiological and biochemical characteristics were measured for Spalangia endius Walker reared on two host species, Musca domestica L. and Bactrocera dorsalis (Hendel). Host associated differentiations in morphology, development and nutrient contents were observed. The egg-adult period of S. endius is 17-21 d, egg and prepupa period is each 1 d for the wasps from the two hosts, while larval period is 8.3 d for the wasps reared on B. dorsalis, longer than that of the wasps reared on M. domestica (6.6 d). The wasps reared on M. domestica had longer pupa period (9.8 d) and adult longevity (12.5 d). Compared with those reared on B. dorsalis, both female and male adult wasps reared on M. domestica had wider head width (1.6 and 1.7 mm). No significant difference was found in fat content between the wasp, while the wasps reared on B. dorsalis had higher content of soluble protein and total sugar. Therefore S. endius would improve their survival abilities and parasitism rate for on B. dorsalis.
