摘　　要：采用野外调查和室内饲养相结合的办法,在对黄褐天幕毛虫的形态特征和生活习性进行观察的基础上,介绍了主要的防治方法。黄褐天幕毛虫在山西省大同市阳高县一年发生一代,是杏树的主要食叶害虫,以卵越冬,第2年5月上旬卵开始孵化,幼虫期共分5龄,5月下旬老熟幼虫开始结茧化蛹,蛹期10～25 d。6月上旬至7月中旬为成虫羽化期,6月下旬达羽化高峰,一天中成虫羽化主要集中在17：00—19：00,羽化当天成虫即达性成熟,可观察到交尾和产卵行为。成虫的寿命为3～7 d,雄蛾的平均寿命长于雌蛾。通过对黄褐天幕毛虫的生物学特征进行系统研究,可为其监测和综合治理提供科学依据。Based on a study on the morphological and biological characteristics of Malacosoma neustria testacea through field survey and laboratory breeding, the main methods of controlling this pest were introduced. The pest occured one generation a year in Yanggao, Datong, Shanxi and was one of the main leaf- eating pests of Armeniaca vulgaris Lam. eggs were found to overwinter and began to hatch in early May of the next year. Larvae passed through 5 instars and the mature larvae began to pupate in late May. The pupal period ranged from 10 to 25 days. Months emerged from early June until mid- July and the peak was observed in late June. The daily emergence peak emerged from 17： 00 to 19： 00. One- day- old adults reached sexual maturity and the behavior of mating and oviposition could be observed. Longevity of adult moths took between 3 and 7 days,but generally males live longer than females. The systematic research of biological characteristics of Malacosoma neustria testacea provides theoretical foundation for its forecast and integrated control.
