Implication

Study investigates kdr mutations and resistance to pyrethroid insecticides in Culex tritaeniorhynchus, suggesting complex resistance mechanisms.

Key Points

This research aims to explore the presence of kdr mutations in Culex tritaeniorhynchus populations and their relationship with insecticide resistance.
Specimens of Culex tritaeniorhynchus were collected from eight locations in the Republic of Korea.
WHO tube bioassays were performed with deltamethrin to assess insecticide resistance.
The occurrence of 1014F kdr mutations was analyzed in correlation with phenotypic resistance.
The 1014F kdr mutation was found in all populations surveyed.
Frequency of the 1014F allele was stable during peak abundance from July to September.
Overall, populations exhibited resistance to pyrethroid insecticides, but no clear link to 1014F mutations was established.
