Thrips attack a number of vegetable, fruit, and flower crops, causing considerable economic damage. Their population levels may be monitored using sticky cards and by direct examination of plant parts using a hand lens. Several cultural control options are available, including avoiding planting thrips-susceptible crops following small grains, managing vegetation in the fields and field edges, using colored mulches, and avoiding high nitrogen levels. Some cabbage and onion varieties are somewhat resistant to thrips attack. Several beneficial insects suppress thrips levels. Organically acceptable pesticides are available for thrips control.
