Insecticidal activity of essential oils against three stored product beetles in stored wheat

Abstract

The experiment were to find out insecticidal activity of essential oils of Chenopodium botrys, Curcuma longa, Citrus reticulata, Lantana camara, Pinus roxburghii, Cymbopogon winerianus, Eucalyptus globules, Cymbopogon flexuosus, Cymbopogon martini were evaluated at 0.1, 0.2, 0.3, 0.4 percent against Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum in stored wheat. The essential oil of Chenopodium botrys, Curcuma longa, Citrus reticulata, Lantana camara, Pinus roxburghii at 0.1, 0.2, 0.3, 0.4 percent were found highly effective against Sitophilus oryzae as they caused hundred percent inhibition as compare to untreated control. The essential oil of Chenopodium botrys, Curcuma longa, Citrus reticulata, Lantana camara, Pinus roxburghii, Cymbopogon winerianus, Eucalyptus globules, Cymbopogon flexuosus, Cymbopogon martini at 0.1, 0.2, 0.3, 0.4 percent were found highly effective against Rhyzopertha dominica as they caused hundred percent inhibition as compare to untreated control. The essential oil of Chenopodium botrys, Citrus reticulata, Lantana camara, Pinus roxburghii at 0.1, 0.2, 0.3, 0.4 percent were found highly effective against Tribolium castaneum as they caused hundred percent inhibition as compare to untreated control.
