白杨透翅蛾(Paranthrene taba-niformis Roott.)主要危害毛白杨、银白杨、杂交杨等。长期以来,对此虫多采用化学农药防治,由于成虫羽化期长,产卵及危害部位隐蔽,不易掌握防治时机,费工费时,特别是大量施用化学农药,污染环境,杀伤天敌,效果不甚显著。为此,于1986—1987年在黄旗堡镇利用白杨透翅蛾性信息素进行了测报和诱捕防治研究,现将结果报道如下。
Paranthrene taba-niformis Roott. Main hazards Populus tomentosa, poplar, hybrid poplar and so on. For a long time, the use of chemical insecticides for insect control has been prolonged. Because of the long emergence period of insects, spawning and the harmful parts are hidden, it is not easy to grasp the timing of prevention and control, time-consuming and labor-intensive. In particular, chemical pesticides are used in large quantities, polluting the environment and killing natural enemies, Significant. To this end, in 1986-1987 in the town of Huangqi Fort Poplar moth pheromone used to measure and trapping prevention and control studies, the results reported below.
