摘　　要：为了保护和利用本地卵寄生性天敌克制甘蔗螟虫的为害,对广西蔗区甘蔗螟虫卵寄生蜂的种类分布以及发生动态进行了调查研究。2011—2014年调查结果表明,甘蔗生长前期在不同蔗区调查的赤眼蜂寄生率均较低。2011年和2014年调查的南宁、崇左和来宾3个蔗区,在甘蔗生长中后期赤眼蜂对甘蔗螟虫的寄生率均明显高于甘蔗生长早期寄生率;在崇左蔗区,黑卵蜂寄生率较高,甘蔗生长早期和甘蔗生长中后期黑卵蜂对甘蔗螟虫的寄生率相差不大。The distribution and occurrence dynamics of egg parasitoids against sugarcane borers were investigated in sugarcane planting areas of Guangxi so as to protect and utilize local egg parasitoids. The survey showed that from 2011 to 2014, the parasitism rates of Trichogramma sp. had been low at early stage. The survey in 2011 and 2014 showed that in the three sugarcane areas of Nanning, Chongzuo and Laibin, the parasitism rates of Trichogramma sp. were significantly higher at the middle-late growth stage of sugarcane than those in early stage. The parasitism rates of Trichogramma sp. were high in Chongzuo, and those at the early stage and the middle-late stage were of little difference.
