| 摘 要： | 从生态位研究角度出发 ,采用 Hurlbert( 1978)生态位重叠和 L evins( 1968)生态位宽度指标 ,对严重危害菜豆的两种潜叶蝇 :美洲斑潜蝇 L iriomyza sativae Blanchard和豌豆潜叶蝇 Phytomyza atricor-nis Meig与主要天敌在时间和空间维度上的生态位重叠和生态位宽度作了定量分析。评价了天敌对猎物的时间及空间跟随作用和控制效果。研究表明 :寄生蜂、蜘蛛、龟纹瓢虫、异色瓢虫对豌豆潜叶蝇有较强的跟随作用和控制效果 |

| Abstract: | The single dimensional niche overlaps and niche widths on the time and space were measured for two important pests, Liriomyza sativae Blanchard and Phytomyza atricornis Meig,and their main natural enemies in bean field by use of Hurlbert's niche overlap format and Levins's niche width ways.The correlation and controlling effect of natural enemies to two leafminers were analyzed.The results showed that the natural enemies,such as parasites, spiders,ladybirds have greater controlling effect on the two leafminers. |
