Insecticide Activity of Essential Oils on the Development of Eggs and Adult of Caryedon serratus Olivier (Coleoptera: Chrysomelidae), Pest of Stored Groundnut c
Journal Title: Journal of Agriculture and Ecology Research International - Year 2016, Vol 9, Issue 2
Abstract
In Burkina Faso, the groundnut is attacked during storage by the weevil Caryedon serratus Olivier. The damage caused by this pest can reach 70% in the absence of protection methods. To protect stored groundnut against C. serratus, essential oils extracted from four plants Lippia multiflora M, Cymbopogon shoenanthus (L.) Spreng, Ocimum americanum Sims and Hyptis suaveolens Poit obtained by hydro-distillation of leaves, were tested on adults and eggs of this pest. The application of essential oils in doses ranging from 10 to 25 µl induces in 24 hours a mortality ranging from 15 to 100% according to the type of essential oils. Thus the use of 10 µl of Lippia multiflora caused 100% mortality in 24 hours against 87.5% for C. shoenanthus, 27.5% for Hyptis suaveolens and 57.5% for Ocimum americanum. The CL50 varied by 10.41 µl in 24 hours for Hyptis suaveolens oil, with Lippia multiflora it is 6.51 µl for only 5.17 µl for Cymbopogon shoenanthus. The result show that the use essential oils against C. serratus in laboratory conditions has significantly reduced the eggs emitted by females and their lives.
