Effects of Early Season Thrips Feeding on Root Development, Leaf Area and Yield

B.A. Roberts, E.A. Rechel


Western flower thrips (WFT), Frankliniella Occidentalis (Pergande), feeding on cotton seedlings (Gossypium hirsutum L., var. Acala SJ-2) grown in growth chambers for 8 weeks caused significant reductions in plant root development, leaf area, and final plant dry matter of both above and below ground biomass when compared with plants protected by a systemic insecticide. Field trials showed similar reductions in early season total plant biomass and harvested lint yields from early thrips damage.
