竹卵圆蝽综合防治技术研究

Studies on Integrated COntrol Techniques for Hippota dorsalis

竹卵圆蝽的防治，可结合营林生产进行冬季垦复施肥，防治效果达５０％左右；黄油加机油以２：１的比例混合在竹基部涂油环１５ｃｍ，效果达９９．７％用５０％甲胺磷于竹基打孔注射原液工１ｍｌ／株，效果这９２％以上。以上各种措施在竹林中结合应用，可达到防治的目的。

Hippota dorsalis could be controlled by fertilization in winter. and the preventioneffect was up to 50% or so. By smearng the mixture of grease and engine oil at a proportionof 2: 1 in bamboo base to form a 15cm - wide ring, it might be prevented, and the effectamounted to 99. 7%; It also could be controlled by injection of 50% methamieophos into thehole Perforated in bamboo base at a dosage of lml Per plant, and the effect was more than92%.
