摘要

背景目的:探讨安达曼和尼科巴群岛布莱尔港机场和港口及其周边地区登革热和基孔肯雅病毒媒介蚊的孳生情况。方法:调查时间为3月和4月,为期两年。对机场、港口居民区和非居民区的储水容器进行了未成熟伊蚊调查。结果:与2024年相比,2023年的隐裂症指数较高。2023年的指数;HI、CI、BI和PI分别为20.1、5.6、32.4和86.0,而到了2024年,这些数值分别下降到6.8、1.9、9.6和17.4。伊蚊两种;Ae。埃及伊蚊和伊蚊。调查容器中发现白纹伊蚊,白纹伊蚊比例较高。2023年,较大的桶/罐的CI值更高,而2024年较小的容器的CI值更高。结论:本研究是首次在Sri Vijaya Puram国际机场和海港进行的综合昆虫学调查。它提供了伊蚊的数据,特别是伊蚊。虫媒病毒的主要媒介埃及伊蚊在安达曼和尼科巴群岛主要脆弱地区的关键入境点出现。研究强调迫切需要系统的病媒监测和有效的控制措施。

Stegomyia mosquitoes in the airport and seaports of Sri Vijaya Puram, Andaman and Nicobar Islands: A popular tourist destination.

Background objectives: The breeding potential of vector mosquitoes of dengue and chikungunya viruses in and around airport and seaport of Sri Vijaya Puram (Port Blair), Andaman & Nicobar Islands was explored.

Methods: The survey was carried out for two years during the months of March and April. All the water holding containers in the residential and non-residential areas of airport and seaport were surveyed for Aedes immatures.

Results: The Stegomyia indices were higher in 2023 compared to 2024. The indices in 2023; the HI, CI, BI and PI were 20.1, 5.6, 32.4 and 86.0, respectively, whereas in 2024, these values declined to 6.8, 1.9, 9.6 and 17.4. Two Aedes species; Ae. aegypti and Ae. albopictus were found in the surveyed containers, with the former in higher proportion. In 2023, larger drum/tanks had higher CI values, while in 2024 smaller containers had more positivity. Ovitrap index showed significant difference (P<0.05) between the two years in both airport and seaport. The percentage positivity for Aedes eggs was 41.2% (n=97) and 36.7% (n=79) in airport and seaport respectively.

Interpretation conclusion: This study is the first comprehensive entomological survey conducted at the Sri Vijaya Puram International Airport and seaport. It offers the data on Aedes mosquitoes, especially Ae. aegypti, principal vector of arboviruses, at critical entry points, which are the key vulnerable zones of Andaman and Nicobar archipelago. Study highlights the urgent need for systematic vector surveillance and effective control measures.
