摘　　要：采用室内昆虫饲养和野外调查相结合的办法,研究了栎黄枯叶蛾(Trabala viahnou gigantina Yang)的生物学特性。结果表明,该虫在延安地区每年发生一代,以卵越冬,越冬期持续8～9个月,第二年5月中下旬卵孵化,7月下旬老熟幼虫开始结茧化蛹,蛹期9～20天;成虫始见于8月下旬,终见于9月底。成虫羽化主要在16:00～22:00,交尾高峰期为4:00左右。雌虫寿命6.12d,雄虫寿命5.89d。The morphological and biological characteristics of Trabala viahnou gigantina Yang was investigated through field survey and laboratory breeding and observation. The results showed that a generation of Trabala viahnou giganti- na Yang lasted one year in Shanxi province and overwinters as eggs. The overwintering stage lasted eight to nine months. The larvae hatched in the middle ten days of May, larvae began to pupate in the last ten days of July and pupal stage was 9-20 days. The adults emerged between the middle ten days of August and the last September. The moth emergence oeeured at 16 ：00-22：00 ,and copulation peak appeared around 4：00μm. The longevity of female moth was 6.12 d and male moth 5.89 d.
