Abstract

Understanding the influence of salinity on the efficacy of mosquito larvicides in brackish water habitats is crucial for effective salt-marsh Aedes taeniorhynchus control. This study investigated the interactive effects of salinity on the toxicity of 3 commonly used mosquito larvicides: Bacillus thuringiensis israelensis (VectoBac® 12AS), spinosad (Natular® SC), and S-methoprene (Altosid® 12AS) against Ae. taeniorhynchus larvae. Four salinity levels (0 ppt [parts per thousand], 8 ppt, 16 ppt, and 32 ppt) were tested in laboratory bioassays. The results revealed distinct responses of these larvicides to varying salinity levels. VectoBac 12AS displayed consistent efficacy across all salinity levels, indicating its suitability for brackish water habitats. In contrast, Natular 2EC exhibited increased effectiveness with higher salinity, making it a preferable choice for saline environments. Altosid 12AS showed its highest efficacy in freshwater, with reduced effectiveness as salinity increased. These findings underscore the need to consider salinity levels when selecting and applying mosquito larvicides in diverse aquatic habitats. Understanding the complex interplay between salinity and larvicide performance is essential for optimizing mosquito control strategies and mitigating mosquito-borne diseases in various environments.

盐度和杀幼虫剂对伊蚊幼虫毒性的交互影响。

了解盐度对咸水生境中蚊子杀幼虫剂药效的影响，对于有效控制盐沼中的伊蚊至关重要。本研究调查了盐度对 3 种常用杀幼虫剂毒性的交互影响：苏云金芽孢杆菌（VectoBac® 12AS）、旋覆花（Natular® SC）和 S-甲氧苄啶（Altosid® 12AS）对泰氏伊蚊幼虫的毒性的交互影响。在实验室生物测定中测试了四个盐度水平（0 ppt [千分之比]、8 ppt、16 ppt 和 32 ppt）。结果表明，这些杀幼虫剂对不同的盐度有不同的反应。VectoBac 12AS 在所有盐度水平下都表现出一致的药效，表明它适合咸水生境。相比之下，Natular 2EC 的药效随着盐度的升高而增强，因此更适合盐碱环境。Altosid 12AS 在淡水中的效力最高，随着盐度的增加，效力有所降低。这些发现强调，在不同的水生生境中选择和施用杀蚊幼虫剂时，需要考虑盐度水平。了解盐度与杀幼虫剂性能之间复杂的相互作用对于优化蚊虫控制策略和减少各种环境中的蚊媒疾病至关重要。
