Abstract:Release of laboratory-reared citrus thrips, Scirtothrips citri (Moulton), onto branches of citrus trees, and capture of falling larvae on sticky sheets, suggested a significant proportion of pupation on the ground. Field experiments were performed with individual trees caged in order to exclude the possibility of random migration of S. citri from tree to tree. Preventing adult emergence from the ground by covering the ground beneath the canopy with sticky plastic sheets resulted in estimates that between 49 and 90% of S. citri adults emerge from the ground. Emerging adults from soil samples collected in the field and from an artificial sand and leaf-litter substrate in the laboratory indicated that most S. citri emerge from leaf-litter or a shallow soil depth. Results have implications for development of future management strategies for S. citri.
