Extract

The sunflower stem weevil, Cylindrocopturus adspersus (LeConte), infests wild and cultivated sunflowers in Colorado, Texas, North Dakota, South Dakota, and Minnesota (Schulz 1978; Charlet 1983). It was first observed in Saskatchewan in a sunflower test plot near Carnduff, in August 1984 (unpublished data). Its abundance and distribution in the major Saskatchewan sunflower growing area, in the Carnduff, Estevan, and Weyburn areas, had not previously been studied.
