Investigations reveal that the species number of parasitic enemy insects in Anhui is more than 100 and 66 of them have been indentified, including parasitic wasps and flies, in 15 families of 2 orders. It is mainly several species of Bracon controlling effectively the smaller tea roller (Adox(?)phyes orana) and the tea geometrid (~-Ectr(?)pis obliqua hypulina). Many Chalcidid species have higher parasitism on scales and the spiny white fly, Aleurocanthus spiniferus; Trichogramma spp. occur in egg period of the smaller tea roller, and the tea roller, Homona cofferea; Scelionid spp. on many moths such as the tea tussock moth, Euproctis pseudoconspersa; and Laraevorid spp. on many moths such as bagworms. So we should protect and make use of natural enemy resource, The Trichogramma was raised and released in tea orchards to control the smaller tea roller, resulting in a substantial controlling effect.
