斯氏线虫对黄曲条跳甲具有较好的控制效果,但由于其田间使用量较大,成本高,生产上无法推广应用。利用斯氏线虫在潮湿土壤生境中具有的主动搜索能力,提出条带式施用方法,不仅显著降低线虫用量,而且对黄曲条跳甲具有较好的控制效果。采用条带施用(条带宽约10cm,带间距22.5cm),可将线虫用量降低到17.5亿条/hm~2,对黄曲条跳甲幼虫的感染率在71.28％左右,防效为72.2％,且与全施无显著差异,并使黄曲条跳甲种群趋势指数Ⅰ值降为2.416,干扰控制指数为0.252。
Aspergillus niger has a better control effect on the yellow strip beetle, but due to its large amount of field use and high cost, it can not be applied in production. Based on the active search ability of the helminthiasis nematodes in wet soil habitat, the banding method was proposed, which not only significantly reduced the amount of nematodes, but also had a good control effect on the beetle. Using strip application (strip width of about 10cm, with a spacing of 22.5cm), the amount of nematodes can be reduced to 1.75 billion / hm ~ 2, the infection rate of yellow tick beetle larvae is about 71.28%, the control effect is 72.2% , And there was no significant difference with the whole plant, and the value of Ⅰ was decreased to 2.416 and the disturbance control index was 0.252.
