Recently, high resistance to pyrethroid insecticides has been associated with ineffective field treatments against Triatoma infestans (Klug) (Hemiptera: Reduviidae) in northern Argentina. Samples were collected from two areas in Argentina (Salta and La Rioja) and one are in Bolivia (Yacuiba), and they were subjected to toxicological and biochemical assays. All populations were resistant to delt...

OBJECTIVE To compare the efficacy of seven pyrethroid insecticides for impregnation of mosquito nets, six currently recommended by WHO and one candidate (bifenthrin), under laboratory conditions. METHODS Tests were conducted using pyrethroid-susceptible and pyrethroid-resistant strains of Anopheles gambiae and Culex quinquefasciatus. Knock-down effect, irritancy and mortality were measured us...

Anopheles gambiae s.s., Anopheles arabiensis, and Anopheles funestus s.s. are the most important species for malaria transmission. Pyrethroid resistance of these vector mosquitoes is one of the main obstacles against effective vector control. The objective of the present study was to monitor the pyrethroid susceptibility in the 3 major malaria vectors in a highly malaria endemic area in western...

Abstract Background The efficacy of insecticide-treated nets (ITNs) containing the insect growth regulator pyriproxyfen (PPF) and pyrethroid insecticides (PPF-ITNs) is being assessed in clinical trials to determine whether they provide greater protection from malaria than standard pyrethroid-treated ITNs areas where mosquitoes are resistant pyrethroids. Understanding entomological mode action t...

BACKGROUND New approaches to delivering insecticides need to be developed to improve malaria vector control. Insecticidal durable wall lining (DL) and net wall hangings (NWH) are novel alternatives to indoor residual spraying which can be produced in a long-lasting format. Non-pyrethroid versions could be used in combination with long-lasting insecticidal nets for improved control and managemen...

The use of synthetic insecticides may cause failures in the biological control insect pests due to undesired side effects on natural enemies and rapid evolution insecticide resistance agroecosystems. Residues neurotoxic can interfere with recognition chemical cues used by find pests. We investigated sub-lethal concentrations pyrethroid lambda-cyhalothrin interaction between aphid parasitoid was...

The present study was aimed to validate an analytical method for the quantification of 19 organochlorine and 2 synthetic pyrethroid pesticide residues in water samples using modified quick, easy, cheap, effective, rugged safe (QuEChERS) extraction Gas Chromatography coupled with Electron Capture Detector (ECD). selected were determined by in-house validated method. evaluating accuracy, precisio...

Over-reliance on synthetic pesticides in insect pest control has caused widespread public and scientific concerns for human health and the environment, especially since many insect pests have already developed resistances to conventional pesticides and Bt products. For this reason, there is a considerable interest in development of alternative control methods for insect pest management. Based o...

In 2021, this study has attempted to analyze the trend of pesticide import over two decades in Nepal. Secondary data obtained from Plant Quarantine and Pesticide Management Center were analyzed know trend. The result showed that pesticides was increasing average annual increase 30.48 tons (a.i.) last twenty-two years. Fungicide had highest followed by insecticide, herbicide these three groups c...
