白杨透翅蛾(Paranthrene tabanjformes Rott)是杨苗主要蛀干害虫,蛀食枝干和顶芽,抑制顶芽生长,形成秃梢。蛀入枝干刺激被害组织增生,呈瘤状虫瘿,易被风折断,影响苗木生长。1980年调查本圃百株有虫5—10头,个别品种40头,大圾店苗圃10—30头。因此,各苗圃对白杨透翅蛾防治非常重视,作者1980年提出“认真搞检疫,把好三道关(剪除虫瘿、喷药保护、堵孔灭虫)、测报要准确,消灭蛀入前”的防治技术措施。“消灭蛀入前”是防治技术的中心环节,予报准确,适期用药,是防治效果优劣的关键。对此1980—1981年作了白杨透翅蛾予测予报方法的调查研究,现将结果整理如下。
Paranthrene tabanjformes Rott is a young shoot that infects pests, eats branches and buds, inhibits the growth of terminal buds and forms bald patches. Moth into the stems to stimulate the proliferation of tissue damage, was tumorous wormwood, easily broken by the wind, affecting seedling growth. In 1980, 100 nurseries with 10 insects were investigated in this nursery, 40 heads of individual breeds, and 10-30 nurseries of large trash stores. Therefore, the nurseries of poplar moth prevention and control of great importance to the author in 1980 proposed “conscientiously quarantine, the good three pass (cut off insects, spray protection, plugging pest control), to accurately measure the newspaper, eliminate the eroded Prevention and treatment of technical measures. ”Elimination of pre-ejaculation" is the center of prevention and treatment technology, to be reported accurately and timely medication, is the key to the prevention and treatment of the pros and cons. In this 1980 - 1981 made the poplar moths to predict the method of reporting research, the results are summarized below.
