Abstract

Adult mosquitoes were collected from 3 areas in northern Thailand with different availabilities of rice fields for larval habitats by using blacklight, truck, and pig-baited traps. Culex tritaeniorhynchus Giles and Culex gelidus Theobald were dominant in all samples. Significant study-area differences were found in light and truck trap collections for Cx. tritaeniorhynchus and Cx. gelidus, but not for Culex vishnui Theobald + Culex pseudovishnui Colless. In pig-baited sample area differences were significant only for Cx. gelidus. Adults of Culex fuscocephala Theobald were relatively rare, comprising only 0.6-7.9% of the total mosquitoes collected. When compared with the results from previous studies in the Chiangmai area, we conclude that Cx. fuscocephala has become a minor species and that changes in the mosquito fauna have occurred in northern Thailand.

摘要

通过使用黑光诱捕器、卡车诱捕器和猪诱饵诱捕器，从泰国北部3个不同稻田幼虫栖息地可利用程度的地区收集成年蚊子。所有样本中，三带喙库蚊（Culex tritaeniorhynchus Giles）和杰氏库蚊（Culex gelidus Theobald）占主导地位。在三带喙库蚊和杰氏库蚊的黑光诱捕器和卡车诱捕器收集样本中，研究区域间存在显著差异，但致倦库蚊（Culex vishnui Theobald）+伪杂鳞库蚊（Culex pseudovishnui Colless）不存在这种差异。在猪诱饵诱捕样本中，仅杰氏库蚊存在显著的区域差异。棕头库蚊（Culex fuscocephala Theobald）成虫相对较少，仅占收集到的蚊子总数的0.6%-7.9%。与清迈地区之前的研究结果相比，我们得出结论，棕头库蚊已成为次要物种，泰国北部的蚊虫群落已发生变化。
