She worked in the National Research Council of Thailand for two years and worked in Tokai University, Japan for Biological Control of insect pests in 1991. At present time, she is working as Associate Professor at King Mongkut’s Institute of Technology Ladkraband (KMITL), Thailand. She has more than 60 publication in different international conferences and several papers in international journals. She has got five research patents in herbal pediculicides for head lice (Pediculus humanus capitis : Phthiraptera) treatments. Her areas of research interest are herbal pesticides or green pesticides for insect pests control, especially in urban insect pests such as mosquito, house fly, cockroach and head louse.

Title: Eco-Friendly Agents for Plant Essential Oils Against  Mosquito Vectors

Abstract:

Currently, mosquito vectors are major medical insect pests in Southeast Asian countries, throughout Asia as well as other areas of the world and they are serious vectors of human and animal diseases such as dengue hemorrhagic fever, malaria, zika, filariasis and heartworm. However, most chemical insecticides have lost the efficacy for mosquito vector control and mosquitoes have developed resistance to them. More importantly, chemical insecticides also have toxic side effect to humans and the environment. Therefore, plant essential oils are one of the best alternatives to chemical insecticides because they are eco-friendly and nontoxic to humans, beneficial insects and non- target organisms, and they have been shown to be easily biodegraded in soil, water and environment. Moreover, the essential oils from Libiatae, Piperaceae, Zingiberaceae, Rutaceae, Illiciaceae and Umbelliferae plants exhibited high toxicity to larvae, pupae and adults of mosquito vectors. In addition, the major chemical constituents of plant essential oils were monoterpenoids and sesquiterpene such as cineol, geraniol, limoneme, terpineol, neolidol and caryophyllene, and monoterpenoids caused mortality of insects by inhibiting the activity of acetylcholinesterase enzyme in the nervous system of the insects. Thus, plant essential oils can be used as an effective eco-friendly agents for mosquito vector control.
