摘要
冬季垦复施肥、人工捕捉能降低虫口密度,有效地减轻竹卵圆蝽的为害。黄油和机油以2:1的比例混合涂环,环宽15cm左右,阻止若虫上竹率90%以上。当竹卵圆蝽已上竹为害后,利用竹腔注射甲胺磷原液1～2ml/株,防治有效率90%以上。对密度较高的小竹林,林间喷烟是防治竹卵圆蝽的好方法。经大面积推广应用证明,防治后经济效益明显。
The population density of Hippota dorsalis will be reduced by cultivation and fertilization or catching by man in winter.Over 90% of the nymphs can be prevented to climb up to bamboo culm by smearing an oil rang(15cm wide 0 on it,the componet of which is the mixed grease and engine oil in proportion as 1 2. During the activity season of the insect,the mortality of more than 90% has occured after treating by bamboo cavity injection with Tamaron 1～2 ml/plant.Smoking generating is the better method for control of H.dorsalis in the bamboo forest with high density,the economic benefit of which is significant after app- lying in large scale.
