摘要
玉米螟是黑龙江省鲜食玉米的主要害虫,严重影响鲜食玉米的品质及外观商品性。为进一步提高对玉米螟的防效,分别在玉米螟成虫期及卵期,田间设置性诱剂诱捕器+释放天敌昆虫赤眼蜂,进行了鲜食玉米主要害虫玉米螟全程绿色防治技术试验。结果表明:对玉米螟的平均防治效果为85.72%,玉米雌穗被害减退率达90.26%,鲜穗产量为18960.00 kg·hm-2,明显提高了对玉米螟的平均防治效果,有效降低了鲜食玉米雌穗被害率,保证了鲜食玉米的品质及外观商品性。
Corn borer is the main pest of fresh corn in Heilongjiang Province,which seriously affects the quality and appearance of fresh corn.In order to further improve the control effect of corn borer,the whole process green control technology of corn borer,the main pest of fresh corn,was tested by setting sex attractor trap+releasing Trichogramma,the natural enemy,in the adult stage and egg stage of corn borer respectively.The results showed that the average control effect on corn borer was 85.72%,the loss rate of female ear of corn was 90.26%,and the fresh ear yield was 18960.00 kg·hm-2 significantly improved the average control effect of corn borer,effectively reduced the rate of female ear damage of fresh corn,and ensured the quality and appearance of fresh corn.
