过寄生和共寄生是影响赤眼蜂繁殖力的重要因素,在大田应用赤眼蜂防治害虫中,蜂种的选择是成败的关键。因此,赤眼蜂对寄主的辨别及种间竞争力的研究,对大量繁殖优质蜂种以及利用优势蜂种具有实践意义。本文对稻螟赤眼蜂进行了有关的研究。一、稻螟赤眼蜂及其他赤眼蜂对被寄生卵的辨别能力 Salt(1934,1937)曾报道,广赤眼蜂 T.evanesens Westwood具有辨别被寄生卵的能力。Klomp等(1980)研究了食胚赤眼蜂T.embryophagum(Hartig)
Parasitism and co-parasitization is an important factor affecting Trichogramma fecundity, Trichogramma application in the field to control pests, bee selection is the key to success or failure. Therefore, Trichogramma host discrimination and interspecies competitiveness of the study, the breeding of high quality bee species and the use of dominant bee species has practical significance. In this paper, Trichogramma ostriniae were studied. First, the the red-bellied beetles and other Trichogramma discernible ability to parasitize eggs Salt (1934,1937) has been reported, the brown-eyed bee T. evanesens Westwood has the ability to distinguish parasitized eggs. Klomp et al. (1980) studied T.embryophagum (Hartig)
