Laboratory studies were conducted to determine some of the attributes of Apanteles plutellae Kurdj., a native parasite to control diamondback moth, Plutella xylostella L. (DBM). The egg-larval period ranged from 6-10 days with mean of 8.33 days. The pupal stage ranged from 6-10 days with a mean of 6.66 days. The life span of the parasitoid when fed with a 30 per honey-water solution was up to 31 days with a mean of 18 days for females and a mean of 12.85 days for males. When fed only with water or no food at all the life span was reduced to 4-5 days. The average number of DBM larvae parasitized by a mated female was 49.8 and for virgin females 9-8. The different larval stage of the host received a varying parasitization with 32 percent of parasitism in the 1st instar, 44 percent in the 2nd instar, 6 percent in the 3rd instar and 5 percent in the 4th instar
