黄地老虎是遍及新疆的主要害虫之一。年年对粮、棉、油、蔬菜等作物均有不同程度的危害。预测黄地老虎超长期发生发展趋势,这是新的尝试。农业生产内部的结构调整,是根据当地自然资源进行“四扩一压”(即扩大麦、棉、绿肥和果树、复播玉米面积,压缩春播玉米面积)等一系列调整措施,导致了种群食料来源的大量减少,改变了种群的生态环境。扩种绿肥又使天敌增大了繁殖基地,地膜植棉使幼虫的取食、产卵受到限制,这将给种群的发生发展带来不利因素,相应地发生危害面积将会减
Yellow tiger is one of the major pests throughout Xinjiang. Every year on the grain, cotton, oil, vegetables and other crops have varying degrees of harm. It is a new attempt to predict the development trend of yellow tigers over the long term. The structural adjustment within agricultural production is based on a series of adjustment measures such as “four expansion and one pressure reduction” (that is, expansion of wheat, cotton, green manure and fruit trees, area of corn replanting and reduction of spring sown corn area) according to the local natural resources, A substantial reduction in source has changed the ecological environment of the population. Expansion of green manure and make natural enemies increased breeding base, plastic film cotton larvae feeding, spawning is limited, which will bring unfavorable factors for the occurrence and development of the population, the corresponding hazard area will be reduced
