Alfalfa seed-Thrips

Frankliniella spp.

Pest description and crop damage Small, slender, quick-moving insects about 0.1 inch long. The insect's economic impact in alfalfa seed production is unknown.

Management-chemical control

Most programs using insecticides to control other injurious insects will reduce thrips populations. Chemical control generally is not recommended solely for thrips because populations rebound dramatically to pretreatment levels.
