黑刺粉虱以幼虫定居在茶树叶片背面刺吸为告,并能招致煤病发生,病虫交加,光合作用受阻,严重时茶叶产量遭受很大损失,是一种值得引起注意的茶树害虫。目前国内对黑剌粉虱抽样方法特别是统计上适宜的抽样方法的研究甚少,田间虫量调查缺乏有效的方法,影响测报、防治工作水平的进一步提高。研究制定黑刺粉虱田间虫量的抽样方法,对于进行科学研究以及生产上开展预测预报,制订合理的防治措施都是十分必要的。
Black thorn whitefly larvae settled in the back of tea leaves sucking sue, and can lead to coal disease, pest infestation, photosynthesis blocked, serious serious loss of tea yield, is a noteworthy tea tree pests. At present, there are few researches on the sampling methods of blackfly whitefly, especially the statistically suitable sampling methods. There is no effective method to survey the insect population in the field, which will affect the further improvement of the forecasting and prevention and treatment work. It is very necessary for us to develop a sampling method for determining the amount of insect pests in the field of black ticks, and to carry out scientific research and forecasting on production as well as to formulate reasonable prevention and control measures.
