小麦吸浆虫(sitodiplosis mosellana Gehin)的发生受温、湿度等气候因子影响极大,特别是化蛹、羽化等发育阶段表现更为显著。本试验于1987年4—5月份小麦吸浆虫化蛹,羽化期间在室内控制温湿度条件下,对活动幼虫化蛹和成虫羽化进度,发育百分率进行了观察,旨在进一步探明不同温湿发对小麦吸浆虫化蛹,羽化的定量温湿指标。为提高测报的精度和分析种群数量变动提供参考,现将初步试验结果简报于下。
The occurrence of sitodiplosis mosellana Gehin is greatly influenced by climatic factors such as temperature and humidity, especially during the developmental stages such as pupation and eclosion. This experiment was conducted in April-May 1987 wheat midge pupal pupation, temperature and humidity control conditions during the indoor temperature, the activities of larvae pupal and adult eclosion progress and developmental percentage were observed in order to further explore the different temperature and humidity on the hair Wheat midges pupal pupae, emergence of quantitative indicators of temperature and humidity. In order to improve the accuracy of the report and analyze the change of the number of the population, the preliminary test results are summarized as follows.
