摘　　要：于2002—2008年在常德市鼎城区林业科学研究所进行竹卵圆蝽生物学特性观察和防治试验，结果表明：该虫在湖南省1年发生1代；林间释放平腹小蜂（Anastatus japonicus Ashmead）防治竹卵圆蝽效果良好，寄生率达69．61％-81．83％，平均为75.68％，因此利用平腹小蜂是一种行之有效的无公害的生物防治措施；在林间补充中间寄主柞蚕卵防治效果较好，补充区竹卵圆蝽卵平均寄生率高达52．68％，而对照区平均寄生率仅23．79％，补充区竹卵圆蝽卵寄生率明显比对照区寄生率提高28．89％。The biological characteristic observation and harmless prevention and control of Hippota dorsalis experimented in Dingcheng District of Changde City from 2002 to 2008. The results of experiments showed that： Hippota dorsalis is occurrence one generation a year in Hunan Province. The obvious effects on prevention and control of Hippota dorsalis was releasing in forest of Anastatus japonicus Ashmead. The parasitic rate was 69.91% to 81.83%, and average parasitic rate was 75.68%. So, using Anastatus japonicus Ashmead is a effective harmless biological prevention and control method. The obvious effects on prevention and control of Hippota dorsalis was supplement releasing of eggs of hosts Chinese Tussah, and the average parasitic rate it was 52.68%, and the average parasitic rate in control area only 23.79%, so it increased 28.89%.
