| heavy metals in mosquito larval habitats in urban kisumu and malindi, kenya, and their impact. | concentrations and distribution of cadmium, chromium, copper, iron, lead, manganese and zinc in mosquito larval habitats in urban kisumu and malindi, kenya and their effect on the presence of anopheles gambiae, aedes aegypti, culex quinquefasciatus and anopheles funestus larvae were investigated. manganese and iron were the most prevalent heavy metals in water of larval habitats in urban kisumu and malindi, respectively. iron was the most prevalent heavy metal in bottom sediments in larval habit ... | 2008 | 17532467 |
| permethrin-impregnated bednet effects on resting and feeding behaviour of lymphatic filariasis vector mosquitoes in kenya. | the impact of permethrin-impregnated bednets on resting and feeding behaviour of mosquito vectors of wuchereria bancrofti, causing human lymphatic filariasis was studied in six pairs of villages (treated and untreated) before and after intervention. the study villages were in kwale district, near the coast of kenya, where bancroftian filariasis is highly endemic, transmitted by a combination of both anopheline and culicine mosquito vectors. mosquitoes were collected weekly in each village, indoo ... | 1998 | 9513939 |
| the role of unused swimming pools as a habitat for anopheles immature stages in urban malindi, kenya. | we conducted larval surveys in habitats located in urban malindi, kenya, in 2005 and 2006 with the goal of determining the productivity of unused swimming pools in relation to other habitats. of the 250 habitats sampled, 66 were unused swimming pools, 93 were wells, 60 were drainage troughs, and 31 were miscellaneous areas, such as septic tanks, swamps, concrete tanks, fish ponds, car-track depressions, and drainage ponds. anopheles gambiae s.1. was the only anophelines species found in the habi ... | 2008 | 18939703 |
| efficacy of vectobac dt and culinexcombi against mosquito larvae in unused swimming pools in malindi, kenya. | the efficacy and persistence of 2 bacterial larvicides, vectobac-dt (bacillus thuringiensis israelensis [bti]) and culinexcombi (bti and bacillus sphaericus [bs]), were tested against anopheles gambiae and culex quinquefasciatus in temporarily unused swimming pools with rainwater in malindi, kenya. pre- and posttreatment larval densities were recorded by sampling with the standard who dipping technique for 8 consecutive days. the larvicides were applied to the pools with a knapsack sprayer. the ... | 2008 | 19181062 |
