刺槐尺蠖是陕西省眉县地区刺槐林的主要害虫。经初步调查,其寄主植物包括林木、农作物和果树等34种,其中刺槐、苹果和梨受害最重。该虫一年发生一代,以结茧蛹在土中过冬。翌年2月下旬开始羽化,3月中旬至4月上旬为盛期,末期于4月中旬。成虫雌雄异型。雄蛾有翅善飞,有趋光性。雌蛾无翅,仅能缓慢爬行。雌蛾一般羽化、交尾和产卵一日内完成。卵多产于一年生枝梢端部阴面,卵粒排列成行,数行或数十行成一卵块,卵块平均有卵462粒。初孵幼虫有吐丝下垂、随风飘荡扩散的习性。幼虫为害期在4月上旬至5月上旬,老熟幼虫于5月中旬开始下树。 根据此虫生物学特性,以地面喷、撒六六六粉消灭成虫效果最好,幼虫幼龄阶段实行树上喷六六六粉也是可行的防治措施。 Robinia pseudoacacia is the main pests of Robinia pseudoacacia in Shaanxi Province. After preliminary investigation, the host plants include 34 species of trees, crops and fruit trees, among which Robinia pseudoacacia, apple and pear hardest hit. The worm occurs a generation a year, in order to cocoon pupa in the soil through the winter. Feather begins in late February the following year, mid-March to early April for the peak period, the end of April in mid-April. Adult dioecious. Male moth winged fly, phototaxis. Female moth wings, crawling slowly. Female general emergence, mating and spawning completed within one day. The egg is prolific in the annual end of the annual shoots cloudy, eggs arranged in rows, rows or dozens of rows into an egg, the egg has an average of 462 eggs. Newly hatched larvae shed silk, floating in the wind drift habit. Larvae infestation in early April to early May, mature larvae in mid-May began to tree. According to the biological characteristics of insects, spraying on the ground, spreading six hundred sixty-six powder to kill the best adults, juvenile larvae implementation of tree spray six hundred sixty-six powder is also feasible prevention and treatment measures.
