昆虫的休眠包括夏眠和冬眠是温带地区昆虫对其生活环境因素季节的或周期性变化适应方式,是重要的物候学现象之一。了解休眠时期及其生态习性,在预测害虫发展动态、制定防治对策有重要意义。沟金针虫(Pleonomus canaliculatus)是黄淮海冬麦区重要地下害虫,早在50年代初就发现其具有夏眠习性,引起夏眠的平均地温为26.8℃(丁文山1953、吴铱等1954)。从70年代开始,麦区普通实行玉米、蔬菜、油料(花生、大豆)间作套种两熟或多熟制,沟
Insect dormancy, including hibernation and hibernation, are one of the important phenomenon of phenology for temperate insects, which adapt to seasonal or periodic changes of their living environment factors. Understanding the dormancy period and its ecological habits is of great significance in predicting the development of pests and in making prevention and control measures. Pleomotis canaliculatus, an important underground pest in the Huanghuaihai winter wheat area, was found to have hypnotic habits as early as the early 1950s. The average ground temperature causing summer dormancy was 26.8 ℃ (Ding Wenshan 1953, Wu Yi et al. 1954). Since the 1970s, corn fields, corn, vegetables (oil, peanut, soybean) intercropping two or more cooked, ditch
