| 摘 要： | 武昌麦田蚜茧蜂共有5种,以燕麦蚜茧峰、烟蚜茧蜂为优势种;重寄生蜂有三种,以黄足分盾细蜂为优势种。蚜茧蜂4月中、下旬进入麦田,5月中旬种群数量达到高峰:蚜茧蜂种群数量主要受寄主—蚜虫密度和4～5月的雨量,相对湿度的影响。麦田蚜茧蜂对麦蚜有一定的控制作用,寄生率最高可达40％以上。解决好重寄生和跟随现象的问题,可提高好苗蜂对麦蚜的控制效果。

| Abstract: | Five species of aphid parasites and three species of hyperparasites were found during the studies conducted in wheat fields at the suburbs of Wuhan City. The predominant aphid parasites were Aphidiua avenae Haliday and A. qifuenais Aahmead. The predominant hyperparasite was Dendrocerus liticeps Hedicke. The parasites occured in wheat fields in mid April. Their populations peaked in mid May. Population dynamics of the parasites were mainly affected by aphid density, rainfall and relative humidity during April and Hay. The parasites were found to exert ca. 40* parasitization on the aphids. Their effect, however, waa limited by hyperparasitization. |
