Safflower, Carthamus tinctorius L., is an important drought-tolerant oilseed crop, used for the production of vegetable oil and protein meal. It is one of the few broadleaf crops that can be used for crop rotation in the small grains agroecosystem of the Northern Great Plains. Safflower is currently produced on about 60 000 ha in eastern Montana and northwestern North Dakota and about 10 000 ha in Alberta and Saskatchewan. There is little information available on the pest insect species on safflower in the Northern Great Plains; however, four pest species have been reported from California, including the westem flower thrips (Frankliniella occidentalis (Pergande)), lygus bug (Lygus hesperus Knight), green peach aphid (Myzus persicae (Sulzer)), and the bean aphid (Aphis fabae Scopoli) (Carlson 1966, 1972).
