is a vector responsible for the transmission of various arboviruses and is considered by the World Health Organization to be one of the main public health problems in the world. This study evaluated the larvicidal and oviposition activity of essential oils from , and and their formulations. Chromatographic analysis by GCMS identified a total of 28, 52 and 18 compounds for the oils of the species , and , respectively. The larvicidal bioassays showed an LC of 67.53 ppm, 92.45 ppm and 35.95 ppm, respectively, for (A), (J) and (P) as well as their binary (J + P, 39.50 ppm; A + P, 51.64 ppm) and ternary (A + J + P, 66.99 ppm) formulations. These oils and formulations also showed deterrent activity at the larvicidal concentrations tested (: OAI: -0.41; : OAI: -0.31; : OAI: -0.62; A + J + P: -0.30; A + P: -0.68; A + J: -0.29; and J + P: -0.30). The oils and their formulations are a potential larvicidal source for mitigating the proliferation of diseases by this vector.
是一种负责传播多种虫媒病毒的媒介，被世界卫生组织视为世界主要公共卫生问题之一。本研究评估了来自[物种1]、[物种2]和[物种3]的精油及其制剂的杀幼虫和产卵活性。通过气相色谱 - 质谱联用（GCMS）的色谱分析分别鉴定出[物种1]、[物种2]和[物种3]精油中的28种、52种和18种化合物。杀幼虫生物测定表明，对于[物种1]（A）、[物种2]（J）和[物种3]（P）及其二元制剂（J + P，39.50 ppm；A + P，51.64 ppm）和三元制剂（A + J + P，66.99 ppm），LC50分别为67.53 ppm、92.45 ppm和35.95 ppm。这些精油及其制剂在测试的杀幼虫浓度下也表现出驱避活性（[物种1]：驱避活性指数（OAI）： - 0.41；[物种2]：OAI： - 0.31；[物种3]：OAI： - 0.62；A + J + P： - 0.30；A + P： - 0.68；A + J： - 0.29；J + P： - 0.30）。这些精油及其制剂是减轻该媒介传播疾病扩散的潜在杀幼虫来源。
