摘　　要：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。Predation of three natural enemies to the young larva ofRhodococcus turanicus was simulated by Holling-Ⅱ and Holling-Ⅲ equation. The results showed that Philodromus cespitum had a strong predatory function. The number of the predation ofP. cespitum was slightly lower than the number of the predation of Hippodamia vanegata. But it was far lower than the number of the predation of Chilocorus geminus, which is one of the dominant species of natural enemies of R. turanicus.
