Acute and sub-lethal toxicity of eight essential oils of commercial interest against the filariasis mosquito Culex quinquefasciatus and the housefly Musca domestica

摘要: Abstract The massive use of synthetic insecticides led to negative effects on the environment and human health. Therefore, researchers looked at natural products as effective alternatives conventional pesticides. Here, commercially valuable essential oils (EOs) were selected from mint (Mentha x piperita, Mentha spicata), basil (Ocimum basilicum), helichrysum (Helichrysum italicum), yarrow (Achillea ligustica), geranium (Pelargonium odoratissimum), cinnamon (Cinnamomum verum) ginger grass (Lippia alba). chemical composition these EOs assayed was analyzed by GC–MS. Then, we investigated their insecticidal potential in acute sub-lethal toxicity assays against mosquito vectors filariasis (Culex quinquefasciatus) house flies (Musca domestica). Against C. quinquefasciatus 4th instar larvae, most toxic EO verum (LC50 = 40.7 μl L−1), followed L. alba (LC50 = 59.6 μl L−1), while M. domestica adults, H. italicum (LD50 = 42 μg adult−1). exposure larvae a concentration (LC30 = 25 mg L−1) reduction adult emergence fertility. Besides, that survived after dose (LD20 = 10 μg adult−1) showed marked decrease male female longevity, well fecundity, fertility, natality. Overall, highly promising two key insect pests. relatively low prices EOs, availability market noteworthy global production bulky materials, make them ideal candidate ingredients be used formulations.
