由于强化食用农产品的安全,推广应用仿生物农药或低毒、无毒的胃毒型杀虫剂,使防治用药作用特点改变,对虫情测报、指导适期防治提出了更精准的要求。茄黄斑螟是为害茄子果实的钻蛀性害虫。为提高其虫情测报技术,笔者通过再次人工饲养,细化了温度间隔,获得了较为齐全的虫态发育历期,并建立了不同温度下其卵、幼虫、蛹3个虫态的回归预测式,提供了各虫态的发育起点温度、有效积温,用于计算推测虫情发生的精准测报理论值。完善了分析影响虫口发生趋势的4大因素、前期灯诱蛾量消长对发生趋势的分析等实用预测分析方法,应用二次逐步回归的相关性检验,找到了影响茄黄斑螟发生的关键气象因素,为对茄黄斑螟的虫情发生预测与指导适期防治提供参考。
Because of strengthening the safety of edible agricultural products, popularization and application of biomimetic pesticides or low toxicity, non-toxic stomach poisoning insecticides, so that the characteristics of the prevention and treatment of medication changes, the insect detection, guidance, prevention and treatment of the proposed more accurate requirements. Eggplant moth is a borer pest that damages eggplant fruit. In order to improve its insect detection technology, the author re-artificially re-cultured, refined the temperature interval, access to a more complete development of the state of the worm state, and established at different temperatures of its eggs, larvae and pupae 3 insect regression prediction It provides the onset temperature and the effective accumulated temperature of all the insect states, and is used to calculate the precise measurement theoretical value of the speculation that the worm occurs. Improve the analysis of the four factors affecting the trend of insect population, the early light trap moth amount of growth trend analysis and other practical prediction analysis method, the application of quadratic regression regression test to find the key to the occurrence of louse Occurrence meteorological factors , To provide a reference for forecasting and guiding insect pest occurrence of Elymus occidentalis.
