Abstract

ABSTRACT: Attractive toxic sugar baits (ATSB) are a novel and effective mosquito control tool based on sugar-feeding behaviors and oral ingestion. In general, there is a demand from consumers for more novel control products with more effective active ingredients. Bacillus thuringiensis israelensis (BTi) is a major larvicide for control of mosquito larvae. This study evaluated BTi as an active ingredient of toxic sugar baits (TSB) against adult Aedes aegypti, Aedes albopictus, and Culex quinquefasciatus, compared with a positive control of 1% boric acid toxic sugar bait. Ingestion of BTi TSB by female mosquitoes resulted in an average mortality at 48 h of 97% for Ae. aegypti, 98% for Ae. albopictus, and 100% for Cx. quinquefasciatus. The study findings suggest ingestible BTi TSBs could be a viable alternative to current mosquito control strategies and programs against adults of these three species of mosquitoes.

苏云金芽孢杆菌作为毒糖诱饵对成年埃及伊蚊、白纹伊蚊和致倦库蚊的评价

摘要：引诱毒糖饵是一种基于食糖行为和口服的新型有效蚊虫控制工具。一般来说，消费者对具有更有效活性成分的更新颖的控制产品有需求。苏云金芽孢杆菌（BTi）是控制蚊虫幼虫的主要杀幼虫剂。本研究评估了BTi作为毒糖诱饵（TSB）的活性成分对成年埃及伊蚊、白纹伊蚊和致倦库蚊的作用，并与1%硼酸毒糖诱饵的阳性对照进行了比较。雌性蚊子摄入BTi-TSB导致埃及伊蚊在48小时内的平均死亡率为97%，白纹伊蚊为98%，致倦库蚊为100%。研究结果表明，可摄入的BTi TSB可能是目前针对这三种蚊子成虫的蚊子控制策略和计划的可行替代方案。

期刊介绍： The Journal of Vector Ecology is an international journal published by the Society for Vector Ecology. It is concerned with all aspects of the biology, ecology, and control of arthropod and vertebrate vectors and the interrelationships between the vectors and the agents of disease that they transmit. The journal publishes original research articles and scientific notes, as well as comprehensive reviews of vector biology based on presentations at Society meetings. All papers are reviewed by at least two qualified scientists who recommend their suitability for publication. Acceptance of manuscripts is based on their scientific merit and is the final decision of the editor, but these decisions may be appealed to the editorial board. The journal began publishing in 1974 and now publishes on-line only.
