摘要
山东省是我国小麦生产主要省份之一，种植面积大，分布区域广，有害生物种类较多，危害较重。为摸清近年来有害生物发生及危害特点，对小麦有害生物种类、发生区划信息进行了调查研究。统计分析了2000年以后小麦有害生物种类增减情况，比较了1991—2011年间小麦主要有害生物发生分布及种群发生演变规律，阐明了20多年来小麦有害生物种群变化规律，并从气象条件变化、栽培措施改变、防治技术措施改进及其它相关因素进行了讨论分析。
Shandong Province is one of the major provinces of wheat production in China, with larger wheat planting area, wider distribution area, more pest varieties and more severe hazards. In order to find out the occurrence and harmful characteristics of pests, their varieties and occurrence region had been investigated and researched. The increase and decrease of pest varieties since 2000 was analyzed. The occurrence, distri-bution and population evolution regularities of wheat main pests from 1991 to 2011 were compared and clari-fied. The changes of meteorological condition and cultivation measure and the development of prevention meas- ure and other factors were discussed.
