“…However, Cx. quinquefasciatus are not exclusively anthropophilic, 28 so gravid traps may include mosquitoes that have fed on birds or other animals, thereby decreasing the likelihood of infection. Sampling from inside houses may increase the likelihood of collecting anthropophilic mosquitoes.…”

Abstract. Monitoring Wuchereria bancrofti infection in mosquitoes (xenomonitoring) can play an important role in determining when lymphatic filariasis has been eliminated, or in focusing control efforts. As mosquito infection rates can be low, a method for collecting large numbers of mosquitoes is necessary. Gravid traps collected large numbers of Culex quinquefasciatus in Tanzania, and a collection method that targets mosquitoes that have already fed could result in increased sensitivity in detecting W. bancrofti-infected mosquitoes. The aim of this experiment was to test this hypothesis by comparing U.S. Centers for Disease Control and Prevention (CDC) light traps with CDC gravid traps in northeastern Tanzania, where Cx. quinquefasciatus is a vector of lymphatic filariasis. After an initial study where small numbers of mosquitoes were collected, a second study collected 16,316 Cx. quinquefasciatus in 60 gravid trap-nights and 240 light trap-nights. Mosquitoes were pooled and tested for presence of W. bancrofti DNA. Light and gravid traps collected similar numbers of mosquitoes per trap-night, but the physiological status of the mosquitoes was different. The estimated infection rate in mosquitoes collected in light traps was considerably higher than in mosquitoes collected in gravid traps, so light traps can be a useful tool for xenomonitoring work in Tanzania.

“…This species is highly endophilic and opportunistic and the females might feed on humans, chickens or many other available hosts, i.e. dogs, horses, cattle, rodents, rabbits, and pigs [1,[35][36][37]. The second most abundant genus was Aedeomyia, represented by the sole tropical species Ad.…”

Background: We assessed the impact of two long-term interventions (insecticide spraying and insecticide-impregnated dog collars), previously directed against sand flies, on the abundance and distribution of mosquitoes (Culicidae) and biting midges (Ceratopogonidae). Both groups are of medical and veterinary importance in Brazil. Our objective was to determine the effect of the sand fly interventions on other biting Diptera.Methods: This study retained the original stratified randomised control trial design but was extended for 12 months. We included the 2 original intervention arms: chicken roosts sprayed with microencapsulated lambda-cyhalothrin and dogs fitted with deltamethrin-impregnated collars and a control arm with no insecticide. Adult mosquitoes and midges were sampled in 280 households at three locations (inside human dwellings, dog sleeping sites, chicken roosts). To maintain the integrity of the study objective we placed sand fly pheromone in the sprayed-insecticide arm. The sand fly pheromone has no effect on the behaviour of culicids or Culicoides.Results: We collected 3,145 culicids (9 genera, 87.6% Culex spp.) distributed relatively uniformly across all 3 arms; 41.9% at chicken roosts, 37.7% inside houses, and 20.3% at dog sleeping sites. We collected 11,464 Culicoides (15 species) found mostly at chicken roosting sites (84.7%) compared with dog sleeping sites (12.9%) or houses (2.4%). Mosquitoes and Culicoides were most abundant during the hot and rainy season. Increased daytime temperature was marginally associated with increased mosquito abundance (z=1.97; P=0.049) and Culicoides abundance (z=1.71; P=0.087). There was no significant association with daily average rainfall for either group. Household-level mosquito and midge numbers were both significantly reduced by the sprayed insecticide intervention 56% [Incidence Rate Ratio, IRR=0.54 (95% C.I. 0.30, 0.97), P≤0.05] and 53% [IRR=0.47 (0.26, 0.85), P≤0.05], respectively, compared to the control. The abundance of both Dipteran groups at dog sleeping sites was unaffected by either intervention. The sprayed insecticide significantly reduced abundance of mosquitoes inside houses (41%), at chicken roosting sites (48%) and reduced midge abundance by 51% in chicken roosting sites.Conclusions: Insecticide sprayed at chicken roosting sites reduced the abundance of mosquitoes and midges at the peridomestic level. Dog collars had no effect on numbers of any group.
