摘　　要：The bionomics of Campoletis chlorideae and the regularity of its seasonal fluctuations were studied in Changsha district,Hunan province. Field investigation indicated that there were ten generations of C. chlorideae a year, of which seven occurred in cotton fields. Three peaks of cotton bollworm parasitization by C. chlorideae were observed, early May to late June, mid August to early September, mid September to mid October respectively. One peak occurred in tomato and tobacco fields, the other two in cotton fields. The parasitization rate ranged from 25.1%- 63.1%. The total development time from egg to adult ranged from 13.0 days at 32℃ to 75.5 days at 11.6℃. Each wasp could parasitize the 5-23 second instar larvae of tobacco caterpillar. C. chlorideae could parasitize the cotton bollworm, beet armyworm and tobacco caterpillar, but preferred the cotton bollworm larvae. C. chlorideae could parasitized 1st-3rd instar larvae of the tobacco caterpillar, but seldom parasitzed 4th-6th instar larvae. Moreover, C. chlorideae preferred second instar larvae. Theoretical models for developmental speed, adult longevity and the influence of temperature were proposed. The overwintering of C. chlorideae Uchida was also discussed. Moreover, methods for utilization of C. chlorideae Uchida in crop protection were presented and the bionomics of Campoletis chlorideae in both the Yangtze River Valley and Yellow River Valley were compared.研究了湖南长沙地区棉铃虫齿唇姬蜂的生物学特性及田间消长规律。棉铃虫齿唇姬蜂在湖南长沙地区年发生约 1 0代 ,以 7个世代发生在棉田。田间出现 3个寄生高峰 ,分别在 5月上旬 - 6月下旬、8月中旬 - 9月上旬及 9月中旬 - 1 0月中旬 ,寄生率平均在 2 5 ,1 - 63,1 %。从卵发育到成虫的平均历期变化范围为 32℃下 1 3天至 1 1 .6℃下 75 .5天。棉铃虫齿唇姬蜂能寄主棉铃虫、斜纹夜蛾和甜菜夜蛾 ,但偏爱寄主棉铃虫。该蜂能寄生棉铃虫 1 - 3龄幼虫 ,很少寄生 4 - 6龄幼虫 ,喜寄生 2 - 3龄幼虫 ,每雌可寄生斜纹夜蛾 2龄幼虫 5 - 2 3头。本文建立了发育速率及成蜂寿命与温度关系的回归模型 ,探讨了越冬问题。
