The red to orange Sorghum Midge (1.3-1.6 mm large) lays its eggs in the heads of Sorghum. The larvae feed on the seeds. As a result of the feeding of the larvae, the seed coats become shriveled and discolored or blank. Heads of infested crops appear small and compressed with blank areas.
The sorghum midge winters in spikelets and in plant residues. They can remain in the spikelets for 2 to 3 years. Under favorably warm conditions, the population starts to grow. The first generations can be found in Johnson grass. The life cycle lasts 6 to 14 days under good conditions. 9 generations or more are possible in these conditions.
