“…2), which was also reported by González-Cabrera et al (2018). This may be a consequence of both the completely recessive nature of the mutation (González-Cabrera et al 2018;Sever et al 2020) and the mite's reproduction system. Indeed, based on the in vitro study of sodium channels in rat neurons (Tatebayashi and Narahashi 1994;Song et al 1996), it is to be expected that the inhibition of only a small fraction of the VGSCs would be sufficient to disrupt neuron repolarization.…”

Pyrethroid target-site resistance mutations in populations of the honey bee parasite Varroa destructor (Acari: Varroidae) from Flanders, Belgium

et al. 2021

The honey bee ectoparasite Varroa destructor is considered the major threat to apiculture, as untreated colonies of Apis mellifera usually collapse within a few years. In order to control this mite, many beekeepers rely on a limited number of approved synthetic acaricides, including the pyrethroids tau-fluvalinate and flumethrin. Due to the intensive use of these products, resistance is now commonplace in many beekeeping regions across the world. In the present study, the occurrence of amino acid substitutions at residue L925 of the voltage-gate sodium channel-the pyrethroid target site-was studied in Varroa populations collected throughout Flanders, Belgium. Dose-response bioassays supported the involvement of the frequently observed L925V substitution in flumethrin resistance, resulting in a 12.64-fold increase of the LC 50 in a Varroa population mostly consisting of homozygous 925 V/V mites. With the presence of L925 substitutions in about four out of 10 screened apiaries, the use of pyrethroid-based varroacides in Flanders, including the recently released PolyVar® Yellow, should be carefully considered.

The widespread use of insecticides has ecological consequences such as emergence of insecticide resistance and environmental pollution. Aedes albopictus is a major vector of dengue virus in the Punjab province, Pakistan. Control of Ae. albopictus with insecticides along with source eradication is critical in the prevention and control of dengue fever but is threatened by the development of insecticide resistance. Here, field strains of Ae. albopictus from eight cities of Punjab were evaluated for resistance against temephos, deltamethrin and permethrin. For temephos, high resistance (RRLC50 > tenfold) was found in larvae of the Rawalpindi strain, moderate resistance (RRLC50 = five- to tenfold) in Multan, Faisalabad, Sialkot, Lahore and Sheikhupura strains, and low resistance (RRLC50 < fivefold) in Kasur and Sahiwal strains. In the case of deltamethrin, high resistance was seen in adults of the strain from Faisalabad, moderate resistance in the strains from Sialkot, Sheikhupura, Lahore and Kasur, and low resistance in Sahiwal, Multan and Rawalpindi strains. For permethrin, adults of all the field strains exhibited high levels of resistance. In synergism bioassays, toxicity of all the insecticides in the field strains significantly enhanced when tested in combination with piperonyl butoxide or S,S,S-tributylphosphorotrithioate, suggesting the probability of metabolic-based mechanisms of resistance. In conclusion, field strains of Ae. albopictus from Punjab exhibit resistance to temephos, deltamethrin and permethrin, which might be associated with metabolic mechanisms of resistance.
