The cotton aphid (Aphis gossypii) is a highly polyphagous pest, which has a host range which includes many commercially grown agricultural and horticultural plant species. Insecticide Resistance has been recorded in cotton aphids since the mid-1960‘s, when organophosphate, carbamate and cyclodiene organochlorines were utilised to control this aphid in a wide range of crops. There have been reports of resistance to pyrethroids and a small number of reports of resistance to nicotinic acetylcholine receptor agonist insecticides in cotton (e.g. Australia, China & USA) and cucurbits & vegetables (e.g. Japan & Korea).
This new Aphis gossypii poster outlines the resistance mechanisms, current status and resistance management guidelines.
