采用HollingⅡ型和Ⅲ型模拟测定了草皮逍遥蛛等3种天敌对吐伦球坚蚧初龄若虫的捕食功能。结果表明:草皮逍遥蛛具有相当的食蚧能力,食量仅稍低于多异瓢虫,但远低于以食蚧为主的孪斑唇瓢虫。
The predation function of three kinds of natural enemies such as turfgrass and spider mite on the first instar nymphs of Conuetosporohertz was studied by Holling Ⅱ and Ⅲ simulation. The results showed that: the turfgrass has considerable ability to eat scales, food intake is only slightly lower than the multi-different ladybugs, but far below the scale-dominated Twin spots lip ladybug.
