灯诱法监测白蛉的初步试验

Preliminary Test of Phlebotomus Surveillance by Light-traps

现场观察了3种诱蚊灯诱白蛉的效果,并试验了无光源灯诱和以葡萄糖水作引诱剂的效果。结果表明,本文试用的3种诱蚊灯所诱的虫种较杂,分拣鉴定的难度较大;无光源诱蚊灯在白蛉栖息地可以捕获少量白蛉,而且标本较为纯净,葡萄糖水没有明显的诱蛉作用。目前用于诱蚊的3种诱蚊灯不适合直接用于白蛉监测,建议试用更有效的白蛉诱引剂。

Different light-traps were tested in Wenxian of Gansu Province, including the light-traps without lamp and with glucose solution as attractant. Results showed that the light-traps attracted more mosquitoes and other insects than sandflies, and it became difficult to pick up the sandflies from gathering packet; the light-trap without lamp captured smaller amount of sandflies but much less other insects; glucose showed no significant effect in attracting sandflies. The existing light-traps are not so effective for Phlebotomus surveillance, and it is suggested that more effective attractants be tried.
