Ecology of anopheles [cellia] sergent II theiobald in the Eastern Desert, Red sea Governorate, Egypt

During a mosquito survey of the inland water sources of the Red Sea Governorate, several larvae and pupae of Anopheles sergentii were collected from a breeding place located 8 km west of El-Quseir town in the Eastern Desert. This finding represents the south-eastern most boundary for this species in Africa. A full description of the ecology of the recorded area as well as of the breeding place is given in this study. In addition, preliminary laboratory observations indicated that An. sergentii females were able to oviposit both fertile and infertile eggs in small cages. This may indicate that this species consisted of stenogamous and eurygamous subpopulations

Reproductive history of anopheles coustani var tenebrous [Doniz] in the laboratory

Field caught Anopheles tenebrosus have been observed to contain few relics on their follicles indicating that they obtained few blood meals. To determine whether these mosquitoes obtains few blood meals or are short lived, we determined the number of gonotrophic cycles for this mosquito. Parental females were used to simulate natural population. We found that these mosquitoes could produce up to 8 gonotrophic cycles, indicating that the field observations is due to limited longevity. In addition, fecundity was maximal initially and decreased with subsequent gonotrophic cycles. Some females required two blood meals to develop a batch of eggs this did not appear to be correlated with the size of the blood meal
