control techniques used to reduce thrips population are composted organic yardwaste, composted mulch applied under plant canopy, and augmentation ofpredatory thrips Franklinothrips orizabensis, F. vespiformis and Leptothripsmc-cornnelli (Hoddle et al. , 2002; Wee et al. , 1999). The University of CaliforniaStatewide Integrated Pest Management Program (2006) suggested integrated pestmanagement (IPM) for controlling thrips. Such a plan would include the optimaluse of natural enemies, removing all weeds under the canopy to eradicatealternative hosts, regular pruning of infected trees, use of a fl uorescent yellowsticky trap, and application of refl ective mulch to disturb host plant orientation of the thrips. Use of fl uorescent yellow sticky traps is limited for monitoring the population of thrips due to the cost of adhesive glues such as the one called tanglefoot (Chu et al. , 2006). Chemical insecticide should be used as a last alternative.If necessary, monochrotophos, methiocarb or carbosulfan can be applied in mangosteen orchards to control thrips.
