Description
Summary:Natural enemies of Marucavitrata (Geyer) feeding concealed inside leafwhorls of a green manure legume, Sesbaniacannabina, were monitored during the 1996 and1997 summer seasons in Taiwan. A braconid,Apanteles taragamae, accounted for anaverage of 92% of all parasitoid specimensreared from M. vitrata larvae and pupae.Other parasitoid species included two otherbraconids: Bassus asper and Dolichogenidea sp., three ichneumonids: Trichomma sp., Triclistus sp., and Plectochorus sp., and two unidentifiedtachinids. All parasitoid species attacked M. vitrata larvae and emerged as mature larvaefrom host larvae (braconids) or as adults fromhost pupae (ichneumonids and tachinids). Oneunidentified predatory staphylinid and threeentomopathogenic fungi: Fusarium sp.Paecilomyces sp. and Beauveriabassiana were also observed attacking M.vitrata larvae. Apanteles taragamae is a solitary endoparasitoid. Its parasitismreached as high as 63% of M. vitratalarvae found attacking S. cannabina. Theparasitism was higher during June to August andreduced during September to November when otherparasitoid species were more active. Ninespecies of hyperparasitoids, all belonging toHymenoptera, were recovered, mainly from thebraconids.
