​​Cotton aphid is a potential pest of cotton in the Southeast and infests the majority of acres each year. Commercially available insecticides can reduce the plant stress associated with aphid feeding, but significant yield responses to aphid control are rarely observed in trials. Commercial insecticides cannot eliminate aphids from cotton. Weekly applications of aphid insecticides were found to reduce populations by about 90% but did not influence the incidence of cotton leafroll dwarf virus, which is vectored by the cotton aphid.​
