this study was designed to evaluate the efficacy of beta-cyfluthrin (responsar 12.5% sc), against a standard susceptible strain of german cockroach, blattella germanica, using three different dosages, at three different exposure times, on two types of surface, parlous (mosaic) and non parous (glassed ceramic of tiles). comparison of the resifts indicated that beta-cyfluthrin at 12.5 a.i.mg/m2, ...

Adult bioassay was conducted in the laboratory on two populations of Culex fuscocephala, a vector of Japanese encephalitis (JE) in India, against two organochloride compounds (DDT and dieldrin), an organophosphate compound (malathion), a carbamate pesticide (propoxur) and two synthetic pyrethroids (deltamethrin and cyfluthrin) using WHO techniques. The adult populations from Mandya an irrigated...

BACKGROUND The psocids Liposcelis bostrychophila Badonnel and L. entomophila (Enderlein) (Liposcelididae) are emerging pests of stored products. Although their behavior, particularly their high mobility, may contribute to the reported relatively low efficacy of insecticides against them, studies to investigate this have not been conducted. The present study aimed to assess the label rate effica...

This study was aimed to investigate thecurrent insecticide resistance status in malaria vector mosquitoes from Dogbo district South-western Benin, West Africa. Larvae and pupae of Anopheles gambiae s.l. populations were collected the breeding sites March July 2020 during first rainy season Couffo department using dipping method. WHO susceptibility tests conducted on unfed female aged 2-5 days o...

The effect of Metarhizium anisopliae (Metschnikoff) Sorokin strain ESC-1 alone and in combination with sublethal doses of commercial formulations of chlorpyrifos, propetamphos and cyfluthrin on mortality of CSMA strain of German cockroach, Blattella germanica (L.), was determined by conducting in vivo studies that included 3 bioassays. Spores of M. anisopliae cultured on SDAY media had germinat...

The efficacy of synthetic pyrethroid-impregnated fabrics was evaluated against Anopheles stephensi, Aedes aegypti, and Culex quinquefasciatus, under laboratory conditions. Results revealed that delta-methrin was significantly superior in comparison to lambdacyhalothrin and cyfluthrin. Results of bioassay tests revealed that deltamethrin was 1.5 and 1.9 times more effective than lambdacyhalothri...

Constructed wetlands are a suggested best management practice to help mitigate agricultural runoff before entering receiving aquatic ecosystems. A constructed wetland system (180 m x 30 m), comprising a sediment retention basin and two treatment cells, was used to determine the fate and transport of simulated runoff containing the pyrethroid insecticides lambda-cyhalothrin and cyfluthrin, as we...

Concentrations of pesticides residues in honey sampled from the major honey producing forest belts in Ghana were determined. Samples were purposively collected and extracted using the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method and analysed for synthetic pyrethroids, organochlorine, and organophosphate pesticide residues. Aldrin, γ-HCH, β-HCH, ∑endosulfan, cyfluthrin, cype...

The overuse of pesticides has been increasing since the 20th century. Depending on this use, non-target organisms are also affected apart from target organisms. Cyfluthrin is a synthetic pyrethroid pesticide used in agriculture, domestic and veterinary medicine against insects. It may affect aquatic as result mixing with ecosystems. This study was aimed to investigate effect cyfluthrin freshwat...
