Protein in the diet of male blowfly chrysomyia albiceps [Widemann]

Laboratory observation showed that males of blowfly, Chrysomyia albiceps [Wiedemann] attract to and feed on meat in adult breeding cages. Experiments under laboratory conditions of 27 +/- 3c and 60- 70 R.H. showed that meat could replace water but could not replace sugar. Feeding on protein diet [meat] did not increase males longevity or their efficiency to mate with more than one female. Mating behaviour and duration of mating process did not also affected. Protein diet could not affect the percentage of egg hatching, percentage of pupation and percentage of adult emergence when the gravid virgin female were mated with protein fed males

Laboratory rearing of wohlfahrtia nuba widemann [diptera-sarcophagidae] in Egypt

A colony of Wohlfahrtia nuba Wiedemann was set up in the laboratory starting from flies collected from Dier El Anba Shounouda from Sohag City. Procedures for successful establishment of a colony and laboratory maintenance of this fly are described. Duration of the whole larval and pupal stage under insectary and controlled condition was studied. Effect of controlled temperatures 17, 27 and 32°C on the duration of the three larval instars, the moulting process and mortality rate were also observed

Effect of larval population density on dynamics of growth in chrysomyia albiceps [Widemann] I: effect of feeding behaviour and growth rate of larvae

The feeding behavior of uncrowded and crowded larvae differed as soon as feeding began. In case of high density populations, larvae tend to form dense clusters and this gregariousness is responsible for much of the injury and resulting predation. Larval growth rate had the same pattern up to 200 larvae per 20 g meat, then this pattern greatly changed with the increase of densities. Larval survivorship remained high at densities up to 160 larvae per 20 g meat, then decreased rapidly as larval density increased. The duration of larval development was extended and synchronization of larval pupal ecdysis was affected. Percentage of pupation and pupal weight were greatly decreased at high densities

Mating behaviour and insemination in anopheles multicolor cambouliu

Mating behavior was described and it was by end-to-end position. The male was capable to inseminate the female efficiently after 24 hours from emergence and this efficiency decreases as the age of the male increases. Male was capable of inseminating more than one female [2.33 +/- 0.33 females]. The female was receptive when it became 24 hours old
