Host preference of Phaedon brassicae for different vegetables
-
摘要: 从取食选择性和产卵选择性2个方面研究了小猿叶甲Phaedon brassicae对小白菜Brassica campestris,菜薹Brassica parachinensis,芥菜Brassica juncea和甘蓝Brassica oleracea等4种十字花科Brassicaceae蔬菜的寄主偏好性。结果表明:小猿叶甲成虫取食表现明显的寄主植物偏好性,产卵选择性和取食选择性基本一致。供试4种寄主植物同时存在时,芥菜为小猿叶甲的最嗜寄主,甘蓝为最不嗜寄主,两者差异显著(P<0.05)。利用小猿叶甲在供试蔬菜上的成虫量和取食面积来分析其取食选择性获得的结果基本一致,两者呈显著性相关(P<0.05)。图2表2参12Abstract: he preference of Phaedon brassicae for 4 cruciferous vegetable hosts, including Brassica campestris, B. parachinensis, B. juncea and B. oleracea were studied in laboratory through comparing their feeding and oviposition preference. The results indicated that P. brassicae had significantly different preference of the 4 host plants. The oviposition preference performed in the same pattern as that of the feeding preference. When there were 4 plants available, P. brassicae preferred B. juncea most and B. oleracea least, which exhibited significant difference (P<0.05). Similar results were achieved by analyzing the number of the adults or the feeding areas on the plant, between which significant correlation (P<0.05) was observed. [Ch, 2 fig. 2 tab. 12 ref.]
