RESUMO

GC and GC/MS analysis of the hydrodistilled volatile oils of the leaves and flowers of Lantana camara L. cv. flava [Verbenaceae] cultivated in Egypt revealed both qualitative and quantitative variations. Experimentally, twenty-nine and twenty-two components were identified in the volatile oils of leaves and flowers representing 91.91% and 95.24% of the total composition of both oils respectively. The major constituents of the leaves volatile oil were caryophyllene < E- > [9.76%], cineol < 1.6- > [9.37%] and pinene < Beta- > [8.15%]. The flowers volatile oils were caryophyllene < E- > [18.20%], humulene < Alpha- > [12.22%] and bicyclegermacrene [10.33%]. Comparing the chemical composition of the volatile oils of the leaves and flowers of L. camara cv., flava from different origins, seasons and even experimental conditions revealed that there are significant qualitative and quantitative variations. The larvicidal effect of the volatile oils of L. camara cv., flava leaves and flowers of was tested against the maturation of Musca domestica L. larvae in the laboratory at concentrations [0.0125%, 0.025%. 0.05%. 0.1% and 0.2%]. They showed mortality rate ranged from 80%-100%. On the other hand, 10-20% of the developed pupae emerged to adults. Adults' fecundity was in larvae given a concentration of 0.0125%. In conclusion, the volatile oils of the leaves and flowers of L. camara cv., flava can be safely recommended in controlling M. domestica 3rd stage larvae
