白杨透翅蛾(Paranthrenc tabaniformis Rott.)是杨树枝干的重要钻蛀性害虫。在找省发生普遍,为害严重。据调查1～5年生幼树一般被害株率达30～50％,造成成林木秃头断梢,林相不整,杨树速生丰产林、防护林及四旁植树威胁极大,但目前对该虫的防治还有很大困难。为探索观察并做了性诱剂粗提和诱引效应初步试验。1982年应用江苏省激素研究所合成的白杨透翅娥性诱剂做了诱蛾效果测定。1983年进行了应用技术及大面积防治试验,现将结果报告如下。
Paranthrenc tabaniformis Rott. Is an important borer pest of poplar stems. In the province to find common, serious damage. According to the survey 1 to 5 year-old saplings generally killed plants rate of 30 to 50%, resulting in forest bald scalding, incomplete forest, poplar fast-growing high yield forest, shelterbelts and tree planting around the threat of great, but the current control of the insect also There is great difficulty. In order to explore and do a preliminary test of crude lure and induced effect of sexual attractant. In 1982, the application of Jiangsu Province Institute of Hormone synthesis Poplar E wing sex attractant made a moth effect determination. In 1983 the application of technology and large-scale control trials, the results are reported as follows.
