Abstract

In recent years, the application of technology in science has raised concernsamong scientists. This report summarized the evaluation of the effectiveness ofmosquito collection by the digital mosquito monitoring system (DMS) using CO2 gas,which could be a potential tool for mosquito collection in the future. The study wascarried out in 2 phases: Phase 1 from September to October 2020; phase 2 from April2021 to July 2021 in 2 districts in Hanoi city, Vietnam. Numbers of mosquitoes werecollected from 2 digital mosquito monitoring systems (DMS). The data of mosquitoescollected from each machine is updated continuously for 24 hours on the system.The number of mosquitoes collected in April was the highest in both locations andfrom 9.00 - 10.00 am of the day. The actual results obtained in the two traps weresignificantly different: The automatically updated insects were 37 630 individuals, andthe collected insects were 48 079 individuals. The majorities of collected insects wereCulex (91.76%) with 23 745; followed by Aedes albopictus (2.49%) with 1 096individuals; Aedes aegypti (1.63%) with 422 individuals and other species (2.37%)with 614 individuals such as fruit flies and drain flies belong to Tipulidae and Pieridaefamily. The automatically updated data of 2 machines showed that mosquitoes hadbeen collected at all time frames of the day, followed by the number of collectedmosquitoes at 9-10 am (11.87%), the lowest number was recorded at 7-8 a.m. (1.14%).
