The Knockdown Resistance (kdr) Mutation in Pyrethroid-Resistant German Cockroaches

Pesticide Biochemistry and Physiology, 1998
Abstract A point mutation in thepara-homologous sodium channel gene has been shown to be associated with knockdown resistance (kdr) in several insect species including the German cockroach. In this study, we analyzed the genomic organization of the region where thekdrmutation resides and then performed polymerase chain reaction (PCR) and sequencing ...

Cross resistance to brevetoxin-3 by kdr and super-kdr mutations in house flies

Pesticide Biochemistry and Physiology
The dinoflagellate Karenia brevis is a causative agent of red tides in the Gulf of Mexico and generates a potent family of structurally related brevetoxins that act via the voltage-sensitive Na+ channel. This project was undertaken to better understand the neurotoxicology and kdr cross-resistance to brevetoxins in house flies by comparing the ...

First detection of kdr, kdr-his, and super-kdr type mutations in Musca domestica (Diptera: Muscidae) from Argentina

Journal of Economic Entomology
Abstract The house fly, Musca domestica L. (Diptera: Muscidae), is a cosmopolitan pest that poses health risks to humans and domesticated animals. Pyrethroid insecticides target the insect voltage-sensitive sodium channel (VSSC) and have been widely used to control house flies in poultry farms in Argentina for more than 3 decades.

Insecticide resistance in Trialeurodes vaporariorum populations and novel diagnostics for kdr mutations

Pest Management Science, 2017
AbstractBACKGROUNDNeonicotinoids, pyrethroids and ketoenols are currently used for the control of Trialeurodes vaporariorum (Hemiptera: Aleyrodidae). In this study, insecticide resistance status and mechanisms were investigated using classical bioassays and molecular techniques.RESULTSDose–response bioassays were performed on 19 Greek populations ...

First Detection of the L1014F kdr Mutation in Triatoma dimidiata, a Vector of Chagas Disease in Mexico

Neotropical Entomology
Chagas disease remains a major public health problem in Latin America, with Triatoma dimidiata (Latreille, 1811) recognized as one of the principal vectors in Mexico. The prolonged use of pyrethroids for vector control has raised concerns about the emergence of resistance, often associated with knockdown resistance (kdr) mutations in the voltage-gated ...

Distribution and frequency of ace-1 and kdr mutations of Culex pipiens subgroup in the Republic of Korea

Acta Tropica
Mosquitoes in the Culex pipiens subgroup are the primary vectors of the West Nile virus. Two members, Culex pallens and Culex pipiens f. molestus, are present in the Republic of Korea (ROK). Because the Culex pipiens subgroup occurs in large amounts, often near human habitation, it is frequently exposed to various insecticides, which is probably ...
