摘要
竹螟是浙江省安吉县的竹子主要害虫。近几年来,由于竹林经营集约化和开展综合防治,我们在竹螟测报调查中发现竹螟的种群结构发生了变化,竹金黄镰翅野螟5a数量占竹螟总蛾量的53.8%,最高年份达78%。原来的测报规程是以竹织叶野螟的发生规律为依据制订的,这对病虫害的预测预报技术提出了新的要求。
Bamboo snout moth is the main bamboo insect in Anji county, Zhejiang province. In resent years, due to the intensive farming and integrated pest control, it is found in the forecasting survey of bamboo snout moth that the population structure is changed, the quantity of Circoboty aurealis （leech） in 5 years accounting for 53.8% of the total bamboo moth and even reching 78% which is the highest in all the years. This poses a new requirement for forecasting technology since the previous forecasting rules were worked out by the occurrence law of Algedonia coclesalis walker.
