Synthesis and Insecticidal Activity of an Oxabicyclolactone and Novel Pyrethroids

Molecules, 2012
Deltamethrin, a member of the pyrethroids, one of the safest classes of pesticides, is among some of the most popular and widely used insecticides in the World. Our objective was to synthesize an oxabicyclolactone 6 and five novel pyrethroids 8–

Experimental hut comparisons of nets treated with carbamate or pyrethroid insecticides, washed or unwashed, against pyrethroid-resistant mosquitoes.

, 2004
The efficacy against mosquitoes (Diptera: Culicidae) of a bednet treated with carbamate insecticide [carbosulfan capsule suspension (CS) 200 mg/m(2)] was compared with four types of pyrethroid-treated nets in veranda-trap huts at Yaokoffikro near Bouaké,

First evidence of resistance to pyrethroid insecticides in Italian Aedes albopictus populations after 26 years since invasion [PDF]

, 2017
Aedes albopictus has spread during the last decades all over the world. This has increased significantly the risk of exotic arbovirus transmission (e.g.

A cytochrome P450 allele confers pyrethroid resistance on a major African malaria vector, reducing insecticide-treated bednet efficacy

Science Translational Medicine, 2019
A cytochrome P450 DNA marker in a major mosquito vector of malaria indicates that pyrethroid resistance reduces bednet efficacy. Tracking insecticide resistance Malaria prevention relies extensively on mosquito control using insecticide-treated bednets ...

An experimental hut evaluation of PermaNet(®) 3.0, a deltamethrin-piperonyl butoxide combination net, against pyrethroid-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes in southern Benin.

, 2010
PermaNet 3.0 is a long-lasting combination net with deltamethrin present on the sides and a mixture of deltamethrin and piperonyl butoxide (PBO), an oxidase synergist, on the top panel.

Susceptibility Status of Malaria Vectors to Insecticides Commonly used for Malaria Control in Tanzania. [PDF]

, 2012
The aim of the study was to monitor the insecticide susceptibility status of malaria vectors in 12 sentinel districts of Tanzania. WHO standard methods were used to detect knock-down and mortality in the wild female Anopheles mosquitoes collected in ...

Dynamics of λ-cyhalothrin disappearance and expression of selected P450 genes in bees depending on the ambient temperature

Open Chemistry, 2021
Temperature has a significant influence on the action of pyrethroids, and their effect increases with decreasing ambient temperature. Using gas chromatography, we assessed the degradation rate of λ-cyhalothrin, active ingredients (AI) of Karate Zeon 050 ...

Losing the ‘arms race’: multiresistant salmon lice are dispersed throughout the North Atlantic Ocean

Royal Society Open Science, 2021
Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in our favour.

Investigation of negative cross-resistance as a resistance-management tool for insecticide-treated nets.

, 2004
Resistance management for insecticide-treated nets (ITNs) remains a challenge. Options are limited, because a safe and highly active insecticide with a persistence of several months is required.

Strain Characterisation for Measuring Bioefficacy of ITNs Treated with Two Active Ingredients (Dual-AI ITNs): Developing a Robust Protocol by Building Consensus

Insects, 2022
Durability monitoring of insecticide-treated nets (ITNs) containing a pyrethroid in combination with a second active ingredient (AI) must be adapted so that the insecticidal bioefficacy of each AI can be monitored independently.
