诱木注干输药防控松褐天牛技术研究

Study on the baited-wood injection of mixture of emamectin benzoate for controlling Monochamus alternatus

利用松褐天牛产卵对诱木的趋性,开展了诱木注干输药防控松褐天牛的研究。结果表明,诱木设置密度为35株/6.67 hm^2时,天牛产卵刻槽数达到187.04个/株,刻槽下降率最高,诱木对松褐天牛的引诱效果最好。采用甲维盐混配剂100 m L插瓶方式注干输药防治效果最好,防治效果达到99.83%。

Based on the tropism of laying eggs on baited-wood for Monochamus alternatus, the author conducted an experiment of injecting chemicals on baited-wood trunks to control M. alternatus. The results showed that the baited-wood had the strongest attraction effeciency when its density was 35 trees per 6. 67 hm^2 ,the borer had 187. 04 egg oviposition scars per tree, with the highest descent rate of scars. It had the highest control effeciency by penetrating bottle with 100 mL mixture of Emamectin Benzoate to control M. altematus through baited-wood trunk injection,with the control effeciency reached 99. 83%.
