| 摘 要： | 2001年秋季在福州郊区对芥蓝田BrassicaalboglabraBailey害虫种群的生态位进行了初步研究,研究结果表明:蚜虫、粉虱和小菜蛾为秋季芥蓝田的优势种害虫,菜青虫、黄曲条跳甲和斑潜蝇为随从种害虫。这些主要害虫的生态位在时间、空间维度和时-空二维上存在明显分化,各种害虫对资源的竞争主要集中在对空间资源的竞争,即随着时间的推移,害虫间的竞争主要集中在对植株上可获得的产卵、取食和栖息的空间资源的竞争。

| Abstract: | The niches of pests in Chinese kale(Brassica alboglabra Bailey) fields were studied in the suburb of Fuzhou in Autumn, 2001. The results show that Aphid(Aphis sp.),whitefly(Trialeurodes sp.) and diamondback moth(Plutella xylostella) were the dominant pests in the field, leaf miner(Liriomyza sp.),Phyllotreta striolata(Fabricius.) and Pieris sp. were the frequent pests in the field. The niches of these pests were differentiated in temporal, spatial , and temporal-spatial dimensions. The competitions among the pests were concentrated on the spatial resources. |
