| Zusammenfassung: | Rhyzopertha dominica (F.) is a pest that causes significant damage in the stored grain of wheat and for to control the indiscriminately use of chemical substances causes resistance to insects, as well as cause problems to environmental and health. Consequently, the effect of essential oils Melaleuca viridiflora Gaertn, Lippia palmeri Watson, and Eucalyptus camaldulensis Dehnhardt on mortality of R. dominica in wheat. These oils were used in various concentrations (5, 10, and 15 ul) and exposure times (24, 48 and 72 h) on the R. dominica insect. The results were obtained by the direct relative proportional in the parameter of mortality with respect to exposure time and concentration of oils. The oils were arranged in the order of importance: M. viridiflora, E. camaldulensis and L. palmeri. From these three oils, M. viridiflora exhibited the best effects on the R. dominica mortality, emergence of adult insects and reduction of weight loss. On the other hand, the oil of L. palmeri showed the best repellency. |
