粘虫是我区小麦上的暴食性害虫。六索线虫(Hexamermis sp.)是第一代粘虫的重要天敌。六索线虫属土源性线虫,分布广,资源丰富,对粘虫幼虫起着自然抑制作用,寄生率高(38—97％)。我们自1975年以来,进行了一系列的研究。 一、六索线虫研究 我们研究的寄生于小麦粘虫幼虫体腔内的线虫,分类学上属于线虫纲,无尾觉器亚纲,咀刺目,索总科,索科,六索属。六索线虫在小麦粘虫体内发育到一定阶段,就离开宿主,
Mythimna separata is the predatory pest on wheat in my area. Hexamermis sp. Is an important natural enemy of the first generation armyworm. Lycoris is a soil-borne nematode, widely distributed, rich in resources, on the armyworm larvae play a natural inhibitory effect, high parasitism (38-97%). We have conducted a series of studies since 1975. One, six cable nematodes We study the parasitic in the body cavity of the armyworm larvae of the armyworm, taxonomically belongs to the Nematoda, non-tail organ subclass, Tsui stomatal, Suo Zongke, Suo Ke, six cable genus. Leptura nematodes in the body to develop a certain stage in the armyworm to leave the host,
