Abstract: To promote the application of Trichogramma for controlling Chilo suppressalis (Walker), three Trichogramma species, T. dendrolimi Matsumura, T. chilonis Ishii, and T. japonicum Ashmead that can be mass-produced easily, were tested in paddy fields in the southern (Hunan Province) and northern (Jilin Province) rice production areas. The three Trichogramma spp. showed similar patterns of parasitism rates of C. suppressalis eggs in the southern and northern rice production areas. T. japonicum showed the best control than T. chilonis and T. dendrolimi, which indicated that T. japonicum is the best choice for releasing against the rice stripped stem borers.
