背景：我们调查了冈比亚按蚊的叮咬规律和季节丰度。还有一个。方法：从布加布拉县和布迪奥普县随机抽取48户家庭的蚊帐诱捕蚊虫，每个月19：00~07：00，连续4个晚上，在布加布拉县和布迪奥普县随机抽取48户家庭，每小时采集一次室内和室外蚊虫叮咬人的数量。记录了2010年1~12月的室内外叮咬分数、按蚊叮咬时间和气候资料。数据分析采用多因素方差分析、Kruskal-Wallis秩和检验和Pearson相关分析。结果：在布迪奥普县和布加布拉地区捕获的蚊子叮咬人类和在室内休息的数量，室内和室外不同时间人类的叮咬密度和叮咬率，以及12个月采样期的蚊子数量。结果：布迪奥普县捕获的蚊子叮咬人类的数量约为布加布拉地区的4倍，其中有一种按蚊。冈比亚亚种捕获量超过了猎物的数量。在这两个区域，夜间叮咬的高峰期都出现在23时至5时之间。冈比亚按蚊和冈比亚按蚊的叮咬时间大多在3：00至6：00之间。和Funestus组。冈比亚按蚊室外叮咬密度。在这两个区域整夜都超过了室内的叮咬密度，而室内和室外的人类叮咬密度。Funestus组明显平等。在这两个区域，室外和室内的人类咬合率相似。在布加布拉县，丰富的一种。冈比亚亚种是依赖于降雨的，而AN。无论有没有降雨，Funestus集团都可以蓬勃发展。在布迪奥普县，两人都是。冈比亚亚种还有一个。结论：冈比亚按蚊的叮咬规律和季节丰度表明，冈比亚按蚊的叮咬习性和季节丰度较高。还有一个。在Kamuli区，密集使用ITN并结合室内滞留喷洒、环境管理和在病媒综合管理背景下改进房屋设计可能是适当的媒介控制策略。
Background: We investigated the biting patterns and seasonal abundances of Anopheles gambiae s.l. and An. funestus mosquitoes in Kamuli District, Uganda.Methods: Hourly indoor and outdoor catches of human biting mosquitoes were sampled from 19.00 to 07.00 hours for four consecutive nights each month using bed net traps in forty-eight houses randomly selected from Bugabula county where insecticide-treated bed nets (ITNs) had been used for at least five years and Budiope county where ITNs had not been used. The indoor and outdoor human-biting fractions, time of biting of the anophelines and climatic data were recorded from January to December 2010. Data were analysed using Multi-way analysis of variance, Kruskal-wallis rank sum test and Pearson correlation. The number of mosquitoes caught biting humans and resting indoors, the indoor and outdoor human biting densities and biting rates during different hours of the night, and mosquito abundances for a twelve-month sampling period in both zones are reported.Results: Approximately four times more Anopheles mosquitoes were caught biting humans in Budiope County than in the Bugabula zone, with An. gambiae s.l. catches exceeding those of An funestus. In both zones, peak night biting occurred between 23.00 and 05.00 hours. The majority of bites occurred between 03.00 and 06.00 hours for both Anopheles gambiae s.l. and funestus group. Outdoor biting densities of Anopheles gambiae s.l. exceeded the indoor biting densities throughout the night in both zones, while the indoor and outdoor human biting densities of An. funestus group were apparently equal. The outdoor and indoor human biting rates were similar in both zones. In Bugabula county, the abundance of An. gambiae s.l. was rainfall-dependent, while the An. funestus group could thrive with or without rain fall. In Budiope county, both An. gambiae s.l. and An. funestus mosquitoes thrived all year round regardless of the amount of rainfall.Conclusion: Considering the biting patterns, and seasonal abundances exhibited by Anopheles gambiae s.l. and An. funestus mosquitoes in Kamuli district, intensive use of ITNs combined with indoor residual spraying, environmental management and improved house designs in the context of integrated vector management may be the appropriate vector control strategy.
