INTRODUCTION
In this study, we used dichloromethane (DCM) and methanol (MeOH) extracts of the Zingiber zerumbet rhizome to evaluate brine shrimp lethality and larvicidal activity on Aedes aegypti and Anopheles nuneztovari mosquitoes.
METHODS
Bioassays were performed by exposing third-instar larvae of each mosquito species to the DCM or MeOH extracts.
RESULTS
Probit analysis with DCM and MeOH extracts demonstrated efficient larvicidal activity against A. aegypti and A. nuneztovari larvae.
CONCLUSIONS
The DCM and MeOH extracts showed higher activity against A. nuneztovari larvae than against A. aegypti larvae, suggesting that the extracts have species-specific activity.
简介
在这项研究中，我们使用姜黄根茎的二氯甲烷（DCM）和甲醇（MeOH）提取物来评估盐水虾对埃及伊蚊和努涅兹库蚊幼虫的致死性和杀幼虫活性。
方法
通过将各蚊虫物种的三龄幼虫暴露于 DCM 或 MeOH 提取物中来进行生物测定。
结果
用 DCM 和 MeOH 提取物进行概率分析显示对埃及伊蚊和努涅兹库蚊幼虫具有有效的杀幼虫活性。
结论
DCM 和 MeOH 提取物对 A. nuneztovari 幼虫的活性高于对 A. aegypti 幼虫的活性，表明提取物具有种特异性活性。
