| anopheles arabiensis and an. quadriannulatus resistance to ddt in south africa. | the malaria control programme of kwazulu-natal province, south africa, includes mamfene and mlambo communities. western-type houses there are currently sprayed with deltamethrin, whereas traditional houses are sprayed with ddt for malaria control. in 2002, mosquitoes of the anopheles gambiae complex (diptera: culicidae) were collected from ddt-sprayed houses, by window exit traps, and from man-baited nets outdoors. larval collections were also carried out at mzinweni pan near mlambo. species of ... | 2003 | 14651656 |
| assessment of the residual efficacy of lambda-cyhalothrin. 1. a laboratory study using anopheles arabiensis and cimex lectularius (hemiptera: cimicidae) on treated daub wall substrates from natal, south africa. | laboratory assessment of the residual efficacy of lambda-cyhalothrin (icon) 10% ai against anopheles arabiensis and cimex lectularius was carried out. the insecticide was applied to daub substrates, simulating the wall surface of houses from 3 areas within the endemic malaria area of natal, south africa. variability in residual efficacy was found between different areas and appeared to correlate to organic content of the substrate. residual efficacy against an. arabiensis ranged from as little a ... | 1993 | 8126474 |
| effect of ddt on survival and blood feeding success of anopheles arabiensis in northern kwazulu, republic of south africa. | the effect of house spraying with ddt on blood-feeding and resting behavior of an. arabiensis in natal province, republic of south africa, was investigated. indoor resting occurred in both control (unsprayed) and replastered (ddt on walls covered due to replastering) huts, but was minimal in fully ddt-sprayed huts. the percentage of bloodfed mosquitoes was greater than 50% in both control and replastered huts, but in the latter huts there was a reduction in the percentage of gravid and an increa ... | 1990 | 2370526 |
