摘要
提出了“害虫再猖獗指数(indexofpopulationresurgence;IPR)”来评价化学杀虫剂激发害虫再猖獗的效应,并以11种杀虫剂处理白背飞虱为例介绍了评判杀虫剂引起害虫再猖獗程度的方法。实例分析表明:IPR是评判杀虫剂激发害虫再猖獗效应的合适指标。
Index of population resurgence(IPR), a new index to evaluate the level of resurgence was suggested. The methods to analyse and judge IPR were exampled by treating whiteback rice planthopper (Sogatella furcifera Horvath) with 11 insecticides. Analysis showed that IPR is an appropriate index.
