Because of damages caused, general occurrence in crops, and high population levels, the most important peanut pest in Brazil is the thrips Enneothrips flavens Moulton (Thysanoptera: Thripidae). A field experiment was carried out during the 2001/2002 growing season, in Campinas and Pindorama, State of São Paulo, Brazil, to evaluate the influence of E. flavens on yield of six peanut cultivars. Treatments comprised three cultivars of the upright type and three of the runner type, with and without chemical control of the insect. Thrips infestation was evaluated by insect countings on young leaflets. Yield and yield reduction percentage due to the lack of thrips control were estimated. The lack of insect control resulted in yield reductions varying from 19.5 to...
