| 摘 要： | 对北京地区大棚栽培蔬菜上西花蓟马种群动态和天敌种类进行调查。结果显示，春茬甜椒在定植30 d内，西花蓟马种群数量增长缓慢，但进入开花期，其数量迅速增长，到6月后持续保持在高数量水平。秋茬甜椒上西花蓟马的种群数量明显低于春季，也主要集中在花中取食。西花蓟马的天敌有瓢虫类、草蛉类和花蝽类，以花蝽类昆虫最多，并对西花蓟马种群具有一定的控制作用。

| Abstract: | The dynamics of western flower thrips（WFT）〔Frankliniella occidentalis（Pergande）〕and its natural enemies on plastic shed cultivation vegetables were investigated during spring and autumn seasons in Beijing．The results showed that the population grew slowly on sweet pepper planted in spring season during 30 days after transplanting. But the pest number increased rapidly with the emergence of flowering period and remained at a high level in June．The number of WFT in autumn season sweet pepper was obviously lower than that in spring．The pest preferred to feed in flowers．The observed natural enemies of WFT were ladybirds，lacewings and flower bugs，and the flower bug（Orius spp.）was the dominant insect，which had some control effect to WFT． |
