Pyrethroid Resistance in Frankliniella intonsa From Inner Mongolia: Evidence for kdr Mutation and Metabolic Involvement

open access: yesEntomological Research, Volume 56, Issue 6, June 2026.
ABSTRACT To evaluate population‐specific susceptibility to pyrethroid insecticides, four field populations of Frankliniella intonsa collected from alfalfa fields in Inner Mongolia were assessed using ingestion and contact bioassays. Four pyrethroids—bifenthrin, cyfluthrin, cypermethrin, and deltamethrin—were tested.

Knockdown resistance (kdr)-like mutations in the voltage-gated sodium channel of a malaria vector Anopheles stephensi and PCR assays for their detection

open access: yesMalaria Journal, 2011
Background Knockdown resistance (kdr) in insects, resulting from mutation(s) in the voltage-gated sodium channel (vgsc) gene is one of the mechanisms of resistance against DDT and pyrethroid-group of insecticides.

Epidemiology of Four Major Canine Tumours in the UK: Insights From a National Pathology Registry With Comparative Oncology Perspectives

open access: yesVeterinary and Comparative Oncology, Volume 24, Issue 2, Page 324-340, June 2026.
ABSTRACT Pet dogs with naturally occurring cancers provide valuable models for comparative oncology and pathology tumour registries offer a powerful resource for onco‐epidemiological research. Here, we analysed the Small Animal Veterinary Surveillance Network (SAVSNET) pathology‐based tumour registry (PTR), one of the largest veterinary tumour ...

A simplified high-throughput method for pyrethroid knock-down resistance (kdr) detection in Anopheles gambiae

open access: yesMalaria Journal, 2005
Background A single base pair mutation in the sodium channel confers knock-down resistance to pyrethroids in many insect species. Its occurrence in Anopheles mosquitoes may have important implications for malaria vector control especially considering the

Erg currents support electrical bursting in murine anterior pituitary corticotrophs

open access: yesThe Journal of Physiology, Volume 604, Issue 12, Page 4834-4850, 15 June 2026.
Abstract figure legend Anterior pituitary corticotrophs are a central component of the hypothalamic‐pituitary‐adrenal (HPA) axis that controls the release of glucocorticoids from the adrenal gland in response to stress. The hypothalamic secretagogue corticotrophin releasing hormone (CRH) promotes electrical bursting of mouse anterior pituitary ...

Combining indoor residual spraying with chlorfenapyr and long-lasting insecticidal bed nets for improved control of pyrethroid-resistant Anopheles gambiae: an experimental hut trial in Benin. [PDF]

open access: yes, 2011
BACKGROUND: Neither indoor residual spraying (IRS) nor long-lasting insecticidal nets (LLINs) are able to fully interrupt transmission in holoendemic Africa as single interventions.

Knockdown-resistance (kdr) mutations in Indian Aedes aegypti populations: Lack of recombination among haplotypes bearing V1016G, F1534C, and F1534L kdr alleles

open access: yesPLOS Neglected Tropical Diseases
Background Knockdown resistance (kdr) mutations in the voltage-gated sodium channel (VGSC) gene are a key mechanism of insecticide resistance in mosquitoes. In Asian Aedes aegypti populations two main VGSC haplogroups with kdr mutations have been identified: one carrying the F1534C mutation and another with V1016G and/or S989P mutations.

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

open access: yes, 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 ...

REDUCED SUSCEPTIBILITY TO DELTAMETHRIN AND KDR MUTATION IN ANOPHELES STEPHENSI LISTON, A MALARIA VECTOR IN INDIA

open access: yesJournal of the American Mosquito Control Association, 2006
The Indian urban malaria vector Anopheles stephensi Liston was selected for deltamethrin resistance for 25 generations (F25) at larval and adult stages separately in the laboratory. There was roughly a 151-fold increase in the lethal concentration (LC)50 and a 99-fold increase in the LC90 in larval selection, when the F25 was compared with the parent ...
