采用实验室和贮烟仓库投虫的方法控制烟草甲虫的不同为害程度,研究了片烟虫害损失的测定方法,同时根据片烟虫害损失的测定方法对国内部分卷烟企业的虫害损失情况进行了调研。结果表明:片烟质量损失率和尸屑率呈极显著正相关,通过尸屑率可估算出片烟质量损失率;46个片烟样品的直接虫害损失率约为0.716%,按有虫片烟占30%的比例推算,所调查卷烟企业的虫害直接损失率约为0.215%。
Tobacco beetle was controlled by laboratory and tobacco storage insects to control the degree of damage. The method for determining the loss of tobacco and pest insects was studied. At the same time, the pest losses of some cigarette enterprises in China were investigated according to the determination method of tobacco and pest losses . The results showed that there was a significant positive correlation between the mass loss rate of cigarette and the carnitine rate, and the rate of loss of tobacco mass was estimated by the rate of cadaver rate. The direct loss rate of 46 tobacco samples was 0.716% The proportion of cigarettes accounted for 30% of the projections, the investigation of tobacco companies direct loss rate of about 0.215% of pests.
