Pyrethroid resistance in tropical bedbugs, Cimex hemipterus, associated with use of treated bednets.

, 2002
When Tanzanian villages were provided with pyrethroid-treated bednets, bedbugs (Cimicidae) disappeared; however, after about 6 years they have re-appeared in these villages. Using a newly devised test-kit, susceptibility tests of bedbugs Cimex hemipterus

Cuticle Thickening in a Pyrethroid-Resistant Strain of the Common Bed Bug, Cimex lectularius L. (Hemiptera: Cimicidae). [PDF]

PLoS ONE, 2016
Thickening of the integument as a mechanism of resistance to insecticides is a well recognised phenomenon in the insect world and, in recent times, has been found in insects exhibiting pyrethroid-resistance.

Evaluation of indoor residual spraying with the pyrrole insecticide chlorfenapyr against pyrethroid-susceptible Anopheles arabiensis and pyrethroid-resistant Culex quinquefasciatus mosquitoes.

, 2010
Chlorfenapyr is a pyrrole insecticide with a unique non-neurological mode of action. Laboratory bioassays of chlorfenapyr comparing the mortality of pyrethroid-susceptible and -resistant Anopheles gambiae s.s.

Distribution and spread of pyrethroid and DDT resistance among the Anopheles gambiae complex in Tanzania.

, 2013
The development of insecticide resistance is a threat to the control of malaria in Africa. We report the findings of a national survey carried out in Tanzania in 2011 to monitor the susceptibility of malaria vectors to pyrethroid, organophosphate ...

Pyrethroid activity-based probes for profiling cytochrome P450 activities associated with insecticide interactions [PDF]

, 2013
Pyrethroid insecticides are used to control diseases spread by arthropods. We have developed a suite of pyrethroid mimetic activity-based probes (PyABPs) to selectively label and identify P450s associated with pyrethroid metabolism.

Reduced Efficacy of Pyrethroid Space Sprays for Dengue Control in an Area of Martinique with Pyrethroid Resistance

The American Journal of Tropical Medicine and Hygiene, 2009
In the Caribbean, insecticide resistance is widely developed in Aedes aegypti and represents a serious obstacle for dengue vector control. The efficacy of pyrethroid and organophosphate ultra-low volume space sprays was investigated in Martinique where Ae. aegypti has been shown to be resistant to conventional insecticides.

Bioactive compounds in insects—Composition, extraction, functionality, food applications, and safety concerns

Food Biomacromolecules, EarlyView.
This review synthesizes 94 studies (2000–2025) exploring edible insects as sustainable sources of peptides, lipids, and chitin. Utilizing “green” extraction, these bioactives offer antioxidant and antimicrobial benefits for functional foods. However, addressing safety concerns like allergenicity and heavy metals through standardized frameworks remains ...

Control of pyrethroid and DDT-resistant Anopheles gambiae by application of indoor residual spraying or mosquito nets treated with a long-lasting organophosphate insecticide, chlorpyrifos-methyl. [PDF]

, 2010
BACKGROUND: Scaling up of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) with support from the Global Fund and President's Malaria Initiative is providing increased opportunities for malaria control in Africa.

Investigasi resistensi Anopheles sp. terhadap insektisida piretroid dan kemungkinan terjadinya mutasi gen voltage gated sodium channel (VGSC)

Jurnal Entomologi Indonesia, 2019
Extensive and continuous use of pyrethroid insecticides to prevent the transmission of malaria can lead to mutations in the voltage gate sodium channel gene (VGSC) in mosquito vectors.
