西藏春尺蠖控灾技术研究

Tibet in the spring of looper control technology research

杨、柳树是西藏雅江地区主要的栽培树种,具有速生、产量高、耐旱、适应性和萌发力强、用途广、经济价值高等特点。春尺蠖(Apocheima cinerariusErschoff)是鳞翅目(Lepidoptera)尺蛾科(Geometridae)。春尺蠖具有发生早,危害期短,幼虫发育快,食量大,常常暴食成灾的特点,本文在其生物学特征的研究基础上,提出持续防治技术。

Poplar, willow is the one in Tibet region the main planting tree species, with fast growth, high yield, drought resistance, strong adaptability and germination force, wide application, high economic value, etc. In the spring of inchworm （Apocheima einerariusErsehoff） is Lepidoptera （l,epidoptera） Geometridae （Geometridae）. Spring inchworm has occurred earlier, harm period short, larval development quick, appetite is big, often overeating by characteristics, based on the study of biological characteristics, continuous technology is put forward.
