为了更好地保护和利用害虫的天敌,从1972年开始,我们对水稻三化螟、稻纵卷叶螟和稻苞虫的寄生性天敌进行了调查。三年来在大田共发现寄生性天敌昆虫共12种(寄生蜂10种,寄生蝇2种)。已知学名的五种:①寄生于三化螟幼虫的爪哇沟姬蜂Isotimajavensis;②寄生于三化螟幼虫的三化螟茧蜂Tropo-bracon schoenobii;③寄生于三化螟卵的等腹黑卵蜂Telenomus dignus;④寄生于稻纵卷叶螟幼虫的螟蛉绒茧蜂Apanteles ruficrus;⑤寄生于稻纵卷叶螟幼虫和蛹的广大腿蜂 Brachymeria obscurata。
In order to better protect and utilize pests’ natural enemies, we started our investigation of the parasitic natural enemies of rice stem borer, rice leaf roller and rice shellworm from 1972 onwards. In the past three years, a total of 12 parasitic natural enemies were found in the field (10 parasitic wasps and 2 parasitic flys). Five known names are known: Isotimajavensis parasitic on the stem borer larvae; Isopimabave schoenobii parasitized on the larvae of the Sesamia inferens; The eggs bee Telenomus dignus; ④ parasitic stem borer larvae in the rice borer Aphelenchoides beaver Apanteles ruficrus; ⑤ parasitic on the rice leaf roller larvae and pupae of the wide leg beetle Brachymeria obscurata.
