在广东稻瘿蚊常见的寄生蜂有5种:(1)黄柄黑蜂Platygaster sp.(群居内寄生天敌);(2)单胚黑蜂Platygaster sp.(独居内寄生天敌);(3)黄斑长距旋小蜂Neanastatus grallartus Masi.;(4)稻长距旋小蜂Neanastatus oryzae Ferriere;(5)斑腹金小蜂Obtusiclava oryzae Subba Rao。这5种寄生蜂中黄柄黑蜂发生较普遍,在一年间大部分时间发生数量多于长距旋小蜂及斑腹金小蜂。稻瘿蚊寄生蜂在晚造秧田及本田寄生率有时达90％以上,对抑制稻瘿蚊的发生起了相当大的作用。 几种常用农药对寄生蜂毒杀作用的比较试验,分别在室内及田间进行。以嘧啶氧磷对寄生蜂毒杀最大,杀虫脒最小。对寄生蜂的毒力大小比较为:嘧啶氧磷>敌百虫>乐果>叶飞散>杀虫脒。
There are five common parasitic wasps in the rice gall midge in Guangdong Province: (1) Platygaster sp. (Social parasitoids); (2) Platygaster sp. Neanastatus grallartus Masi .; (4) Neanastatus oryzae Ferriere; (5) Obtusiclava oryzae Subba Rao. The five kinds of parasitoids in the yellow-bellied black bee occur more commonly in most of the year occurred more than the number of long-winged bee and Bursaphelenchus. Parasitoids of rice gall midge in late rice and Honda parasites sometimes more than 90% parasitized, to inhibit the occurrence of rice gall midge mosquito played a significant role. Several commonly used pesticides on parasitozoas poisoning comparative test, respectively, indoors and in the field. Pyrimidine to phosphorus most parasitic apocalypse killing, chlordimeform minimum. The virulence of the parasitic wasp size comparison: pyrimidine phosphorus> trichlorfon> dimethoate> Yefei San> chlordimeform.
