These suggestions incorporate current knowledge of aphid biology and ecology, cultural management practices and insecticide resistance management. Pubescent varieties develop higher aphid numbers than glabrous varieties. However, most commonly planted commercial varieties are pubescent with relatively little difference between them. Aphid numbers in cotton can be lower following crops that leave a high level of residue. Light reflectance from the residue slows aphid reproduction.
Planting dates influence aphid abundance.
Aphid numbers during August are higher in late June-planted cotton than cotton planted either in April or May in the West Texas production region. May 15 - June 7. These dates also optimize boll weevil management. Where practical, land preparation no later than April will allow producers to have fields ready for planting during the preferred planting period. Plant to assure an adequate and uniform stand.
