摘　　要：对广西国有钦廉林场受肉桂双瓣卷蛾和潜叶蛾危害的樟树人工林在用药防治前后的受害株数与总虫口数量进行统计,比较2种樟树害虫在农药影响下的种群动态变化及不同药剂的防治效果。结果表明,樟树肉桂双瓣卷蛾于当年4月下旬开始出现,在人为药防的干预作用下,其虫口数量总体上呈波动状态。药防效果随时间减退,且暴发期虫口数量增加的速度相对较快,防治后一段时间虫口数量降低,但随时间推移,虫口数量逐渐回升,出现峰值。说明在一定药效期内,农药对肉桂双瓣卷蛾幼虫的发生具有抑制作用。The number of damaged plants and total population of camphor plantation damaged by Polylopha cassiicola and Lyonetia sp.in Qinlian forest farm of Guangxi were counted before and after drug control,and the population dynamics changes of two camphor pests under the influence of pesticides and the control effects of different pesticides were compared.The moth began to appear in late April of that year.Under the intervention of man-made drug control,the number of moths fluctuated on the whole.The effect of drug control decreased with time,and the number of insect population increased relatively rapidly during the outbreak period.The number of insect population decreased for a period of time after control,but with the passage of time,the number of insect population gradually rebounded and peaked.The results showed that the pesticide had an inhibitory effect on the occurrence of the larvae of Polylopha cassiicola.The number of moths also decreased significantly after treatment,but then increased.This study provided a theoretical reference for the prevention and control of Polylopha cassiicola and Lyonetia sp..
