Extract

The sunflower maggot is native to North America. It has been recorded from Maine and New Brunswick through Quebec to Alberta and California and as far south as New Mexico and Florida. It was collected by Criddle at Aweme, near Treesbank, Manitoba, in 1905 and is known to have been present in cultivated sunflowers in southern Manitoba since 1944. Heavy infestations have occurred since 1948.
