摘要: 为大面积推广应用赤眼蜂防治水稻二化螟提供技术依据,选择目前易于大批量人工繁殖的3种赤眼蜂:松毛虫赤眼蜂Trichogramma dendrolimi Matsumura、螟黄赤眼蜂Trichogramma chilonis Ishii和稻螟赤眼蜂Trichogramma japonicum Ashmead,分别在南方产区湖南和北方产区吉林两地进行了其对田间水稻二化螟Chilo suppressalis(Walker)卵的寄生率和防治效果的试验调查,并分析比较不同赤眼蜂种间的控害能力。结果表明,在南北水稻产区,供试的3种赤眼蜂对二化螟卵的田间寄生率及控害效果的变化趋势相同,从高至低依次为稻螟赤眼蜂、螟黄赤眼蜂和松毛虫赤眼蜂。稻螟赤眼蜂明显优于螟黄赤眼蜂和松毛虫赤眼蜂,表明稻螟赤眼蜂为控制水稻田二化螟的优势蜂种。

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.

Key words: Trichogramma, Chilo suppressalis, parasitization, control efficacy
