Thrips feed in buds, folded leaves, and other unexposed areas of plants. This makes them difficult to treat with an insecticide. They feed by sucking juices from the plant causing stippling, or small scars, on leaves, flowers and fruit.
Thrips have been collected from 29 plant orders, including various berries, cotton, day lilies, field crops, grass flowers, legumes, peonies, privet hedges, roses, azaleas, rhododendrons, trees, vines, and weeds.
Thrips are tiny, narrow insects with feathery wings which are difficult to detect. The adult female will lay eggs on the leaf surface. Once they hatch they suck the juices out of flowers and new leaf shoots.
