Preferred breeding habitats of Aedes Aegypti (Diptera- Culicidae) Mosquito and its public health implications in Dares Salaam, Tanzania

چکیده
The larval habitats of the mosquito Aedes aegypti L (Diptera-Culicidae) were investigated in urban Dar es Salaam, using larval traps (old tyres, vegetations, outdoor water storage containers and flower pots). The study was carried out in the four sampling sites namely, Vingunguti, Julius Nyerere International Airport (JNIA), Mbagala and Mkuranga (Vikindu). The aim was to assess the influence of habitat changes in urban Dar es Salaam (the capital city of the united republic of Tanzania) on the preferred breeding habitats of Ae. Aegypti mosquitoes and its possible public health implications on the residents of the City. Aedes aegypti mosquitoes bred in all the habitats sampled. Old tyres recorded the highest number of Ae. aegypti mosquitoes followed by water storage containers and vegetation. Flower-pots habitat was the least preferred, with the lowest number of Ae. aegypti mosquitoes.Other mosquito species belonging to five genera were also collected and these were found to live in sympatry with Ae. aegypti larvae. Statistical analysis revealed a significant difference in species occurrence in the four larval habitats sampled. The availability of the habitats to support the breeding of Ae. aegypti mosquito, which are potential vectors of urban yellow fever, Chikungunya fever, Dengue fever and Rift Valley Fever Viruses implies that theresidents of Dar es Salaam City are at risk of mosquito-borne diseases should an outbreak occur. It is therefore important that, residents of the City are enlightened on environmental factors that contribute to mosquito breeding and that, the Government together with the community institute proper sanitation measures to reduce mosquito breeding habitats.

The larval habitats of mosquitoes were investigated in Abeokuta, Nigeria in order to determine the breeding sites of the existing mosquito fauna and its possible public health implications on the residents of the City. The habitats were sampled between August 2005 and July 2006 using plastic dippers and a pipette. The habitats were grouped as ground pools/ponds, gutters/open drains, tyres, dome...

Aedes albopictus (Diptera: Culicidae) was first reported in Central Africa in 2000, together with the indigenous mosquito species Aedes aegypti (Diptera: Culicidae). Because Ae. albopictus can also transmit arboviruses, its introduction is a public health concern. We undertook a comparative study in three Cameroonian towns (Sahelian domain: Garoua; equatorial domain: Douala and Yaoundé) in orde...

Studies on the seasonal fluctuation of Aedes aegypti were undertaken in different localities of Delhi, during 2000. The Aedes aegypti population was found to be prevalent in all the localities in Delhi. Water coolers and tires were found to be the preferred breeding habitats of Aedes mosquitos in the city. Aedes aegypti, being hygroscopic, showed a phenomenon of annual pulsation. It tends to mo...

Three mosquito species, Culex tarsalis Coquillett, Culex quinquefasciatus Say and Aedes aegypti L. (Diptera: Culicidae), were examined in laboratory binary choice experiments to investigate whether fish exudates from the mosquitofish, Gambusia affinis (Baird & Girard) (Cyprinodontiformes: Poecilliidae), deter oviposition and whether the responses of these mosquito species to fish exudates in ov...

Aedes aegypti and Culex quinquefasciatus are mosquito vectors for several tropical diseases that represent a current public health problem. The ecological requirements for each species are different, however, both species show high biological adaptability, which promotes their coexistence in the same breeding sites. The purpose of this study was to assess the effect of larval association betwee...
