Water mites (Hydrachnidia) are common external parasites of the medically important mosquitoes (culicidae). Between April 2014 and April 2015, 64 mites from three genus, Arrenurus 71.9%, Limnochares 3.1%, and Hydrachna 25.0%, were collected from female mosquitoes in two rural locations near Cuiabá, Mato Grosso, Brazil. Dipterous species parasitized by water mites belonging to seven species: Anopheles (Nys.) darling, An. evansae, Aedes (Och.) scapularis, Ae. serratus, Mansonia (Man.) wilsoni, Psorophora (Jan.) ferox, Ps. varipes. The most common specimens to accommodate the water mites were Anopheles (Nys.) darlingi and Psorophora (Jan.) varipes. The prevalence of parasitism of mosquitoes by water mites found in this study was less than 5. However, few studies have addressed the ecological role of mites and their biotopes, as well as host-parasite interactions in Brazil.

Background:Aedes aegypti(Diptera:culicidae)is the main vector of the dengue virus *** vector control is mainly based on reducing the vector population through interventions,which target potential breeding ***,in Tanzania,little is known about this vector’s habitat productivity and insecticide susceptibility status to support evidence-based implementation of control *** present study aimed at assessing the productivity and susceptibility status of *** mosquitoes to pyrethroid-based insecticides in Dar es Salaam,***:An entomological assessment was conducted between January and July 2015 in six randomly selected wards in Dar es Salaam,*** productivity was determined by the number of female adult *** mosquitoes emerged per square *** susceptibility status of adult *** females after exposure to 0.05%deltamethrin,0.75%permethrin and 0.05%lambda-cyhalothrin was evaluated using the standard WHO *** rates were recorded after 24 h exposure and the knockdown effect was recorded at the time points of 10,15,20,30,40,50 and 60 min to calculate the median knockdown times(KDT50 and KDT95).Results:The results suggest that disposed tyres had the highest productivity,while water storage tanks had the lowest productivity among the breeding habitats Of *** *** sites demonstrated reduced susceptibility to deltamethrin(0.05%)within 24 h post exposure,with mortalities ranging from 86.3±1.9(mean±SD)to 96.8±0.9(mean±SD).The lowest and highest susceptibilities were recorded in Mikocheni and Sinza wards,***,all sites demonstrated reduced susceptibility permethrin(0.75%)ranging from 83.1±2.1%(mean±SD)to 96.2±0.9%(mean±SD),in Kipawa and Sinza,*** low mortality rates were observed in relation to lambda-cyhalothrin(0.05%)at all sites,ranging from 83.1±0.7(mean±SD)to 86.3±1.4(mean±SD).The median KDT_(50)for deltamethrin,permethrin and lambda-cyhalo
