3·Dynamic analysis of poplar stem borer was done with population density, crowded level and percentage of damaged trees on sample plots.
本文采用平均虫口密度、拥挤度和被害株率作为标准地的指标,对杨树蛀干害虫的危害状况作动态分析。
4·Based on 5 years of investigation, the authors presented a non-hazard system for control of the rice stem borer in Jilin province in Northeast China.
基于5年调查试验,结合国内外有关工作,提出吉林省水稻二化螟无公害防治技术体系。
5·Therefore, these low fish-toxicity pyrethroids can be considered as candidates for replacing highly toxic organophosphates and resistance management for the rice striped stem borer.
