abstract
The Laboratory Experiment were conducted to develop economically feasible, ecologically compatible and safe formulations based on essential oils against three stored product coleoptera e.g. Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum. The highly effective essential oils of Calistemon citrinus, Chenopodium botrys, Cinnamomum tamala, Artemisia annua, Citrus reticulata, Curcuma longa, Lantana camara, Murraya koenigii and Pinus roxburghii were used at 0.2 percent and their two component formulations at 0.1 percent each and three component formulations at 0.07 percent each and four component formulations at 0.05 percent each formulated and tested for their fumigant toxicity against Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum. The all tested essential oil based formulations either alone or in two, three and four component formulations were found highly effective against Sitophilus oryzae, Rhyzopertha dominica and Tribolium castaneum. The tested essential oil based formulations were completely suppressed the feeding and breeding of three stored product coleoptera. The all tested essential oil based formulations did not affect the germination quality of wheat seed.
