Sunflower Midge

The sunflower midge, Contarinia schulzi (Gagné)
Because of the difficulty in timing adult emergence and in affecting the cryptic larvae, insecticides are not effective in controlling sunflower midge. Altering planting dates has not had a consistent effect on midge infestations. Some commercial hybrids are tolerant or resistant to the sunflower midge. Sunflower midge management relies on cultural practices done prior to planting because of the absence of effective chemical controls. In locations when sunflower midge infestations have occurred, new fields should be established away from fields damaged the previous season. To minimize the risk of all fields being at the most susceptible stage at midge emergence, several planting dates should be used and tolerant hybrids planted.
