【摘要】 研究和分析了赤眼蜂大面积防治不同发生类型区(丘陵区、山区和越冬代、第三代)马尾松毛虫的试验情况,发现利用赤眼蜂对丘陵区越冬代马尾松毛虫进行规模防治效果最佳,其次是山区越冬代马尾松毛虫。对第三代松毛虫的防治,效果不理想。

【Abstract】 Experiments in the large area prevention and control of D. punctatus in different areas (hills, mountains, overwintering generation and third gerneration) by T. dendrolimus were researched and analyzed in the paper. The results showed that the best effects on prevention and control of the overwintering generation of D. punctatus by T. dendrolimus were in the hill area, and second best in the mountain area. There were low effects in the prevention and control of the third generation of D. punctatus by T. dendrolimus.
