Due to conservation and rehabilitation efforts, mangrove forests represent some of the largest environmental niches in Malaysia. However, there is little information on the potential risks posed by mosquitoes that are directly and indirectly associated with mangrove forests. To study the potential health risk to humans active within and in close vicinity of mangrove forests, this research focused on the day biting habits of mosquitoes in mangrove forests of Kedah, Malaysia. The bare leg catch (BLC) method was used to collect adult mosquitoes during a 12-h period from 7:30 a.m. to 7:30 p.m. in both disturbed and less disturbed areas of mangroves. In total, 795 adult mosquitoes from 5 genera and 8 species were collected, and over 65% of the total mosquitoes were collected from the less disturbed area. The predominant species from the less disturbed area was ; in the disturbed area the dominant species was . The peak biting hour differed for each species, with and recorded as having a bimodal biting activity peak during dawn and dusk. For an erratic pattern of biting activity was recorded in the less disturbed area but it peaked during the early daytime for both collection points. Overall, the distinct pattern of day biting habits of mosquitoes within mangroves peaked during dawn and dusk for the less disturbed area but was irregular for the disturbed area throughout the day. The presence of vectors of pathogens such as for both areas raises the need for authorities to consider management of mosquitoes in mangrove forests.
由于保护和恢复工作，红树林是马来西亚一些最大的环境生态位。然而，关于与红树林直接和间接相关的蚊子所带来的潜在风险，信息却很少。为了研究在红树林内部及附近活动的人类面临的潜在健康风险，本研究聚焦于马来西亚吉打州红树林中蚊子的日间叮咬习性。采用裸腿诱捕（BLC）方法，在上午7:30至下午7:30的12小时内，在红树林的受干扰和较少受干扰区域收集成年蚊子。总共收集到来自5个属8个物种的795只成年蚊子，超过65%的蚊子是在较少受干扰区域收集到的。较少受干扰区域的优势物种是 ；受干扰区域的优势物种是 。每个物种的叮咬高峰时间不同， 和 在黎明和黄昏时记录为具有双峰叮咬活动高峰。对于 ，在较少受干扰区域记录到叮咬活动模式不稳定，但在两个采集点都是在白天早些时候达到高峰。总体而言，红树林内蚊子日间叮咬习性的明显模式在较少受干扰区域的黎明和黄昏时达到高峰，但在受干扰区域全天都不规律。两个区域中诸如 等病原体载体的存在，使得当局有必要考虑对红树林中的蚊子进行管理。
