Abstract:
Parasitoidism, host range, host size and production ability of Microplitis tuberculifer Wesmael were studied. The results showed that M. tuberculifer parasitize mainly 1st and 2nd instars larvae of Spodoptera exigua, Leucania separata and Prodenia eridenia. 1st, 2nd and 3rd instars larvae of Leucania separata were strongest with the selective index of 0.42, 0.54 and 0.05, respectively. Fourth instar larva and above could not nearly be parasitized. M. tuberculiferr could mate and parasitize at the day of their eclosion. Before 6th day female could parasitize 90 percent of target pest. The average cocoons produced by one female was 30 and the maximum was 89 at 19-25℃. The average life span of female was 6 days and 13 days at most. It had stronger ability to propagate and control target pest.
