Is outdoor-resting behaviour in malaria vectors consistent? Short report from northern Ghana
نویسندگان
چکیده
Background: Recent studies have observed vectors resting predominantly outdoors in settings where anti-vector tools are extensively deployed, attributed to selection pressure from use of control tools. This present study examined if the outdoor behaviour vector population is random or indicative a consistent preference one site over other. Methods: Mark-release-recapture experiments were conducted with outdoor-resting Anopheles gambiae and An. funestus mosquitoes collected two villages northern Ghana during rainy dry seasons. Mosquitoes marked fluorescent dyes released indoors. The controlled indoor-resting mosquitoes, which outdoors. Species all recaptured identified assessed for consistency their behaviour. Results: A total 4,460 comprising gambiae sensu lato (s.l.) (2,636, 59%) complex (1,824, 41%) released. Overall, 31 (0.7%) mostly location 25 (81%) s.l. 6 (19%) funestus complex. Only 3 (10%) found indoors they majority outdoor-recaptured arabiensis (11, 39%), followed by coluzzii (7, 25%); whereas indoor-recaptured coluzzii. For experiment, 324 constituting 313 (97%) 11 (3%) complex However, none these was neither nor More captured season, but this not statistically significant (Z=0.79, P=0.21). Conclusions: These results suggested tendency retain behaviour. Further investigations required ascertain emerging malaria populations occurrence.

Variations in household microclimate affect outdoor-biting behaviour of malaria vectors
Background: Mosquito behaviours including the degree to which they bite inside houses or outside is a crucial determinant of human exposure to malaria. Whilst seasonality in mosquito vector abundance is well documented, much less is known about the impact of climate on mosquito behaviour. We investigated how variations in household microclimate affect outdoor-biting by malaria vectors, Anophele...

متن کاملCompost Adoption in Northern Ghana
Despite describing a decline in soil fertility, Northern Ghanaian smallholders have not universally adopted use of organic, sustainable soil amendments such as compost. Farmers’ decisions about whether to use compost depend on their need and ability to do so. The agroecological context of a single rainfall season with low soil organic matter means that farmers’ need to compost is a paramount fa...
متن کاملTransfusion-transmitted malaria in Ghana.
BACKGROUND In sub-Saharan Africa, the prevalence of malaria parasitemia in blood donors varies from 0.6% to 50%. Although the burden of TTM in malaria-endemic countries is unknown, it is recommended that all donated blood is screened for malaria parasites. This study aimed to establish the incidence of TTM and identify a suitable screening test. METHODS Pregnant women, children, and immunocom...
