Coelomomyces Stegomyiae

Coelomomyces stegomyiae (Chytridiomycetes, Blastocladiales) infection in adult female Aedes aegypti (Diptera, Culicidae) is located primarily in the ovaries. Fungal hyphae do not penetrate the germaria or follicles but instead lie between the tunica propria and epithelial sheath within each ovariole and between the epithelial sheath and the peritoneal sheath of the ovary. Aedes aegypti is an anautogenous mosquito requiring a blood meal for egg development; similarly, fungal hyphae in infected ovaries will not differentiate to form resting sporangia until after the mosquito has taken a blood meal. The fungus restricts receptor-mediated endocytosis of vitellogenin by the plasma membrane of the oocyte so that few, if any, vitellin yolk granules form. Thick-walled resting sporangia have formed 72 h after the blood meal has been taken and these will be oviposited by the females in place of the aborted eggs.

Aqueous Suspensions

Factors affecting the persistence of deposits from aqueous suspensions of insecticides have been studied.There is an inverse relationship between particle size of insecticides and the initial contact toxicity to mosquitos. The influence of particle size on effectiveness decreases as the intrinsic toxicity of the insecticide increases. The compounds investigated can be arranged in order of immediate contact toxicity to mosquitos (Aëdes aegypti): dieldrin ≥ gamma-BHC > aldrin > DDT.

Transmission of Dengue Hemorrhagic fever by Aedes aegypti mosquito is influenced by several environmental factors, namely temperature, humidity, and rainfall. This study aims at identifying the relationship between environmental factors and dengue vector population density. A longitudinal entomological study was performed in the city of Kassala, Sudan, in 20 households in each of the 20 clusters during the three seasons of 2014 and 2015. Data were collected using spotlight in any water-holding container where immature stages of Aedes spp. were detected. Immature mosquitoes were counted and classified into larvae and pupae. Ambient temperature and relative humidity in each cluster were recorded, and the total rainfall of Kassala City was obtained from the main Meteorological Station in Khartoum. There was a significant positive correlation between rainfall and number of Ae. aegypti females at Garb Algash and Khatmia areas. Larval instar 4 and pupae were positively correlated with high humidity at Khatmia and Altora areas. In autumn season, there was no strong correlation of all the stages with all climatic variables. There was also positive significant correlation between ambient low temperature and number of females in autumn season.
