Insecticide Activity Study Of Essential Oils Of Daucus Carota (L.) Ssp. Carota and Chenopodium Ambrosioïdes (L.) On White Larvae of Melolontha Melolontha


In the goal of natural alternative research of insecticide properties and limited risks by environment, extracted oils from Daucus carota (L.) ssp. carota and Chenopodium ambrosioïdes (L.) have been tested on white larvae of Melolontha Melolontha. This study has two essays: the first has been realized in petri boxes where larvae haves been made in contact with different oil concentrations of Daucus carota (L.) ssp. carota and Chenopodium ambrosioïdes (L.). The second has been realized on the basis of the first essay so as only concentrations which have good results tested in pots containing soil issued of natural milieu. During all the period of exposition doses LC50 and LC99 have been determined as well as the lethal times, required for the death of 50% (LT50) and 90% (LT99) white larvae exposed to different concentrations of essential oils. We notice that essential oil of Chenopodium ambrosioïdes (L.) leads to very significative insecticide effect on Melolontha Melolontha larva rather than on Daucus carota (L.) ssp. carota.
