BACKGROUND Insecticide resistance is one of the serious problems for German cockroach control program. This study was conducted to determine the bendiocarb and Carbaryl resistance mechanisms in German cockroaches using the piperonyl butoxide (PBO). METHODS Bioassay tests were conducted with 4 to 6 different concentrations of both insecticides with four replicates of 10 susceptible strain cock...

The carbamate compounds are a class of cholinesterase inhibiting pesticides, and bendiocarb is the most widely used carbamate insecticide used to control disease vectors (mosquitoes, flies, household and agricultural pests). In this study histological structure of rabbit lymphoid tissue and selected parameters of homeostasis after bendiocarb administration were studied. Bendiocarb was perorally...

Bendiocarb is a broad-spectrum insecticide recommended for malaria control by the World Health Organization (WHO). Still, bendiocarb poses toxic risk to populations of nontargeted aquatic organisms. Thus, our study was aimed evaluate sub-lethal effects exposure on zebrafish (Danio rerio) embryos assessing physiological, developmental, and biochemical parameters. Bendiocarb-induced adverse embry...

Malaria control relies heavily on pyrethroid insecticides, to which susceptibility is declining in Anopheles mosquitoes. To combat pyrethroid resistance, application of alternative insecticides is advocated for indoor residual spraying (IRS), and carbamates are increasingly important. Emergence of a very strong carbamate resistance phenotype in Anopheles gambiae from Tiassalé, Côte d'Ivoire, We...

Intense and persistent use of DDT for malaria control has increased resistance and induced exophilic behavior of Anopheles pseudopunctipennis. An evaluation of bendiocarb and DDT to control this species in Sinaloa, Mexico, showed that, in spite of DDT-resistance, both insecticides produced similar effects. Feeding patterns were analyzed to explain these results. Resting mosquitoes were collecte...

Background: Programmatic monitoring of insecticide resistance in disease vectors is mostly done on a large scale, often focusing on differences between districts, regions or countries. However, local heterogeneities in residual malaria transmission imply the need for finer-scale data. This study reports small-scale variations of insecticide susceptibility in Anopheles arabiensis between three n...

The present study was conducted to investigate the impact of carbamate insecticide - bendiocarb on the testicular structure of adult rabbits. Bendiocarb was perorally administered daily for 10 and 30 days, at a dose 5 mg/kg of body weight. After the histological sampling the tissues were investigated and compared with control. After the bendiocarb administration the absolute and relative testic...

The operational impact of deltamethrin resistance on the efficacy of indoor insecticide applications to control Aedes aegypti was evaluated in Merida, Mexico. A randomized controlled trial quantified the efficacy of indoor residual spraying (IRS) against adult Ae. aegypti in houses treated with either deltamethrin (to which local Ae. aegypti expressed a high degree of resistance) or bendiocarb ...

Background. Eave tubes are novel mosquito control devices that help to protect households against malaria vectors and other mosquitoes. They are installed in the upper walls of human habitations after the eaves have been closed. Mosquitoes trying to enter through these tubes are intercepted by electrostatic netting that can be treated with a variety of insecticides. Using video, mosquito behavi...
