Chemical constituents and combined larvicidal effects of selected essential oils against anopheles cracens (Diptera: Culicidae)

A preliminary study on larvicidal activity against laboratory-colonized Anopheles cracens mosquitos revealed that five of ten plant oils at concentration of 100ppm showed 95-100% larval mortality. The essential oils of five plants, including Piper sarmentosum, Foeniculum vulgare, Curcuma longa, Myri...
