Efficacy of three insecticides on rat flea [Xenopsylla cheopis] infesting rodents in Giza Governorate, Egypt

The extensive use of insecticides in public health and agriculture sectors is the main reason for development of resistance in fleas associated in domestic rodents. The present work was planned to investigate the insecticidal efficacy of Lambda-cyhalothrin, Chlorpyrifos and Fenitrothion against rat flea [Xenopsylla cheopis] infesting rodent species in Giza Governorate, Egypt. The lethal concentration LC[50] and Lc[90] of population percent were obtained from the established regression log concentrate-response lines. Data indicated that the values of lethal concentration [LC[50]] were 0.293, 1.725 and 2.328% for Lambda-cyhalothrin, chlorpyrifos and Fenitrothion, respectively. The values of lethal concentration [Lc[90]] were 0.467, 2.839 and 5.197% for Lambda-cyhalothrin, chlorpyrifos and Fenitrothion, respectively

survey on dipterous flies and their densities in Alexandaria and hurgada, Egypt

The present study was performed from January to December 2009 to identify the dipterous flies associated with human and animal diseases in Alexandaria and Hurgada. The results indicated that 10233 flies belonging to 10 families, 18 genera and 21 species were trapped from Alexandarja and 41669 flies belonging to 9 families, 14 genera and 16 species were trapped from Hurgada. M. domestica L. and Coproica vagans [Haliday] were the most abundant species in the two studied areas. Statistical analysis showed that species of the two families Muscidae and Sphaerocerjdae were significantly higher in Hurgada than Alexandarja due to the spread of garbage, fermented fruits and human and animal excreta

Chemical composition and insecticidal activity of the volatile oils of leaves and flowers of lantana camara L. cultivated in Egypt

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

influence of temperature and feedings on development, adult longevity and larviposition of parasarcophaga Hirtipes Wiedemann [diptera: sarcophagidae]

In this study, a number of sarcophagid flies was collected from the area of Dokki, Giza and kept in laboratory under normal weather conditions. Adult development, longevity and reproduction of Parasarcophaga hirtipes were studied in relation to variations of temperature and relative humidity during the period from January to May 2002. The mean longevity of adults of both sexes decreased with the increase of temperature and the decrease of relative humidity. The mean larval duration periods were also significantly decreased with the increased temperature, but the mean pupae duration for both sexes did not change significantly during the experiment. The total development time from larvae to adults of both sexes decreased with the increase of temperature. The mean longevity of adults female and male was affected by the presence of both sexes together every day rather than their presence together for only three-day period to allow for one mating to occur. The effects of meat, liver and fish as food constituents on the developmental period, longevity and larviposition of the fly were investigated under a variation of relative humidity and temperature. The mean longevity of adult of both sexes was increased on feeding on meat. The change was not affected when fed on liver and fish. The mean development period of larvae and pupae and the total development period of both sexes did not significantly increase with liver feeding
