Abstract
The frequency of pyrethroid- and neonicotinoid-resistant genes was investigated in the cotton aphid, Aphis gossypii Glover collected from watermelon fields in Inami Town, Wakayama Prefecture, in 2015, 2018 and 2022. The Aphis clone possessing the genes resistant to both insecticides occurred at a frequency of 19.5% in 2022. Low mortality rates for neonicotinoids and pyrethroids were observed in this clone.
