About Western Flower Thrips
Western flower thrips (Frankliniella occidentalis) are 1–1.2 mm slender insects with feathery fringed wings that are major greenhouse and field pests of virtually all flowering crops and ornamentals worldwide. They feed by puncturing individual plant cells and sucking contents, causing silvery streaking, scarring, and flower deformation. Far more damaging, they are the primary vector of tomato spotted wilt virus and impatiens necrotic spot virus, which can devastate entire greenhouse crops. They have developed resistance to most insecticide classes and exploit high temperatures in greenhouses to reproduce year-round, requiring rigorous integrated pest management approaches.
