摘要

埃及伊蚊最近的地理扩张对全球公共卫生构成重大挑战。在加州，这些入侵性蚊子现在出现在25个中部和南部县的300多个城市。In2Care®蚊子站使用生物控制剂来瞄准伊蚊，与现有的综合媒介管理战略相结合，显示出了希望。本研究评估季前部署In2Care站点对伊蚊的影响。蚊数量。建立了两个队列：一个队列有17个站点在季前（4 - 11月）部署站点，另一个队列有15个站点在旺季（7 - 11月）部署站点，在2022-2024年期间维持。每月BG-2哨兵诱捕器数据显示，伊蚊数量显著减少。季前In2Care站点的埃及伊蚊丰度：从2022年的31.2只/捕蚊夜降至2023年的20.1只/捕蚊夜和2024年的13.2只/捕蚊夜，同比减少34-36%。高峰期的In2Care站点在部署后四周蚊子数量减少了24-36%。季前In2Care站点的蚊虫丰度比旺季站点低22-34%。这些结果表明，在蚊虫季节之前早期部署In2Care站点可显著减少伊蚊。并加强现有的病媒综合管理规划。

PRE-SEASON DEPLOYMENT OF IN2CARE® MOSQUITO STATIONS TO CONTROL AEDES AEGYPTI POPULATION IN THE WEST VALLEY REGION OF SAN BERNARDINO COUNTY, CALIFORNIA.

The recent geographic expansion of Aedes aegypti poses a significant global public health challenge. In California, these invasive mosquitoes are now present in over 300 cities across 25 central and southern counties. The In2Care® Mosquito Station, which uses biological control agents to target Aedes mosquitoes, has shown promise when integrated into existing integrated vector management strategies. This study evaluated the impact of pre-season deployment of In2Care stations on Ae. aegypti populations. Two cohorts were established: 1 with 17 sites deploying stations pre-season (April-November), and another with 15 sites deploying during peak season (July-November), maintained during 2022-2024. Monthly BG-2 Sentinel trap data showed a significant reduction in Ae. aegypti abundance at pre-season In2Care sites: from 31.2 mosquitoes/trap-night in 2022 to 20.1 in 2023 and 13.2 in 2024, with a year-to-year reduction of 34-36%. Peak-season In2Care sites showed a 24-36% reduction in mosquito abundance four weeks post-deployment. Pre-season In2Care sites maintained 22-34% lower mosquito abundance than peak-season sites. These results demonstrate that early deployment of In2Care stations prior to the mosquito season significantly reduces Ae. aegypti populations and reinforces the existing integrated vector management programs.
