| 摘 要： | 以Levins生态位宽度指数和Pianka生态位重叠指数估计发生在同一营养阶层的 4种主要十字花科植物害虫营养生态位、时间生态位和空间生态位的生态位宽度和重叠度。结果表明小菜蛾、黄曲条跳甲、菜粉蝶和小猿叶甲 4种昆虫的生态位并不完全重叠。

| Abstract: | The niche breadth and niche overlap of four pests on the same trophic level (cruciferous plants) were estimated with Levins index and Pianka's measure in three dimensions: trophic level, time and spatial resources array. The results show that the four species: the diamondback moth Plutella xylostella, the cabbage butterfly Pieris rapae, the striped flea beetle Phyllotreta striolata and the vegetable beetle Phaedon brassicae are able to coexist in competition. |
