Anopheles gambiae s.l. (Diptera: Culicidae) in Muleba, Tanzania has developed high levels of resistance to most insecticides currently advocated for malaria control. The kdr mutation has almost reached fixation in An. gambiae s.s. in Muleba. This change has the potential to jeopardize malaria control interventions carried out in the region. Trends in insecticide resistance were monitored in two...

Applications of bendiocarb produced a high insecticidal residual effect lasting up to 3 months on the most common indoor house surfaces. No significant decreases in mosquito man-biting rate levels were observed between treated and untreated villages. It was shown that almost equal proportions of intra- and peridomicillary mosquitoes came into contact with the insecticide, indicating that mosqui...

A field strain of the German cockroach (Melia), collected from the kitchen of a hotel in Kuala Lumpur, Malaysia demonstrated moderate resistance to bendiocarb and low resistance to propoxur and deltamethrin when tested with modified W.H.O. glass jar method. Low resistance was also detected when the strain was tested with DDT. Resistance level to bendiocarb and deltamethrin was partially suppres...

Objective: We evaluated the susceptibility status of Anopheles gambiae in two communities Ikorodu, Lagos, Nigeria to DDT, deltamethrin, lambda cyhalothrin and bendiocarb.
 Methods: immature stages were collected from their habitats surveyed community allowed emerge before exposure adult females discriminating doses WHO insecticides including cyhalothrin, bendiocarb malathion. PBO synergist...

OBJECTIVE To define the insecticide resistance status of Triatoma infestans to deltamethrin (pyrethroid), malathion (organophosphate) and bendiocarb (carbamate) in Bolivia. METHODS Fifty populations of T. infestans were sampled in Bolivian human dwellings. Quantal response data were obtained by topical applications of 0.2 μl of insecticide-acetone solutions on nymphs N1 of the F1 generations....

background: the german cockroach, blattella germanica (l), is a world wide hygienic pest that is very difficult to control. extensive usage of insecticides may develop resistance to a variety of insecticides, causing failure to control. this study was designed to determine resistance of hospital-collected strains of the german cockroach to carbamate and organophosphorous insecticides. methods: ...

BACKGROUND Insecticide-treated nets (ITNs) and indoor residual spraying (IRS) of houses provide effective malaria transmission control. There is conflicting evidence about whether it is more beneficial to provide both interventions in combination. A cluster randomised controlled trial was conducted to investigate whether the combination provides added protection compared to ITNs alone. METHOD...

As with other insects, resistance to insecticides has become a limiting factor in the use of insecticides to control mosquitoes. Mosquito control depended on the use of insecticides for a long time (initially organochlorines, followed by organophosphates, carbamates and pyrethroids). This study aimed to determine the susceptibility of Anopheles arabiensis adult to the public health and agricult...
