| 摘 要： | 对福州郊区菜心田害虫种群的生态位进行了初步研究。结果表明，黄曲条跳甲、小菜蛾和蚜虫为秋季菜心田最主要的害虫。不同害虫的生态位上存在明显分化，黄曲条跳甲在时间生态位上占有较多资源，小菜蛾则在空间生态位上占有相当多资源。并分析探讨了田间不同害虫种群混合发生的竞争机制及相应的害虫控制策略。

| Abstract: | In this paper, the niches of different pests in flowering Chinese cabbage (Brassica parachinensis Baily) field were studied in the Fuzhou's suburb during autumn,2001. The results showed that stripped flea beetle [Phyllotreta striolata (Fab.)], diamondback moth [Plutella xylostella (L.)] and aphid (Aphis sp.) were the key pests in the field. The niche of stripped flea beetle was more specialized on temporal dimension while that of diamondback moth was more specialized on spatial dimension. The competition among the pests in the field were analyzed and pest management tactics were discussed. |
