目的 观察嗜人按蚊是否存在“同期突增”和“同期突发”现象 ,以期探讨嗜人按蚊存在迁飞特性的可能性。 方法 在浅山区约 2 km2 范围内 ,选择位于不同山沟内相互隔离的 3个自然村 ,采用室内全夜灯光诱捕法 ,观察嗜人按蚊、中华按蚊和三带喙库蚊是否存在“突增突发”现象。 结果 嗜人按蚊和三带喙库蚊均存在“突增突发”现象 ;中华按蚊未出现这种现象。 结论 嗜人按蚊存在迁飞特性的可能性。
Objective To observe the existence of “simultaneous spikes” and “sudden onset” of Anopheles anthropophagus in order to explore the possibility of migratory characteristics of Anopheles anthropophagus. Methods In the area of about 2 km 2 in shallow mountain area, 3 natural villages isolated from each other in different ravines were selected and indoor night-time light trapping method was used to observe whether there was a sudden increase in Anopheles stephensi, Anopheles sinensis and Culex tritaeniorhynchus Sudden “phenomenon. Results Both Anopheles anthropophagus and Culex tritaeniorhynchus had the phenomenon of ”sudden increase". Anopheles sinensis did not appear this phenomenon. Conclusion Anopheles anthropophagus has the possibility of migration characteristics.
