| 目的 探讨贪食库蚊幼虫捕食致倦库蚊幼虫的数量及其对其它蚊虫孳生的影响。方法 人工单个和群体饲养贪食库蚊幼虫 ,计算平均每条捕食的数量 ,并对有和无贪食库蚊孳生的积水进行幼虫密度计数。结果 单个和集体饲养每条四龄贪食库蚊幼虫 2 4h平均捕食四龄致倦库蚊幼虫分别为 5.6和 6 .0条 ;贪食库蚊幼虫不食四龄致倦库蚊幼虫的头壳和呼吸管 ;三龄贪食库蚊幼虫可捕食与之等大的其它蚊幼虫 ,贪食库蚊幼虫之间有相互厮咬现象 ;有贪食库蚊孳生的积水其幼虫密度为 3.3条 /勺 ,且只有一、二龄幼虫 ;无贪食库蚊孳生的积水其幼虫密度为 2 9.7条 /勺 ,可见各期幼虫及蛹。结论 贪食库蚊幼虫可抑制甚至中断其它蚊幼虫的孳生 |

| Objective: To observe the amount that Culex haljfaxii prey on Culex pipiens fatigans,and the influence of culex halifaxii upon the breeding of other mosquito. Methods: The average amount of each Culex halifaxii preying on Culex pipiens fatigns was counted by raising a single one and colony.The density of larva in the stagnant water with or without the breeding of Culex halifaxii was also counted. Results: Each the fouth stadiu Culex halifaxii larva by raising a single one and colony prey on the fouth stadium Culex pipitens fatigans larva by an average of 5.6 and 6.0 for 24 hours respectively. The Culex halifaxii didn't eat the skull and respiratory tube of the fouth stadium Culex pipiens fatigans larva.The Culex halifaxii larva of the third stadium could prey on the other mosquito larva of the same size.The phenomenon of bitting each other among the Culex halifaxii larvas was observed. The larva density in stagnant water with the breeding of Culex halifaxii was 3.3 a spoon,and only the first and second larva could be found. While in the stagnant water without breeding of Culex halifaxii was 29.7,and each period larva and pupa could be seen.Conclusion: The Culex halifaxii can control and discontinue the breeding of the other mosquito larva.
