| 摘 要： | 本文首次从产卵选择性和取食选择性两方面研究黄曲条跳甲对芥菜、萝卜、大白菜、山西白和芥蓝等5种十字花科蔬菜的寄主选择性.结果表明,黄曲条跳甲的产卵选择性与取食选择性基本一致,芥菜为其最嗜寄主,芥蓝为最不嗜寄主,两者差异显著(P<0.05).利用黄曲条跳甲在供试植株上的落虫量和取食面积来分析其取食选择性时,所得结果一致,且两者呈显著性正相关(r=0.9597,P<0.05).但该跳甲对不同寄主的子叶取食选择性与真叶取食选择性两者间表现不同.

| Abstract: | The paper deals with the oviposition preference and feeding preference of Phyllotreta striolata for 5 species of cruciferous vegetables.The oviposition preference performed in the same pattern as that of the feeding preference,with Brassica juncea as the most favorable host plant and the Brassica alboglabra as the least favorable host plant.Similar results were achieved when valuating the feeding preference by the feeding area and the number of beetles on the plants,which showed significant correlation with each other(r=0.9597, P<0.05).The beetle presented feeding preference in different patterns between cotyledon and real leaves. |
