The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), is the main vector of the tomate spotted wilt virus (TSWV), and the "minute pirate bug", Orius insidiosus (Say), is an efficient predator. To evaluate the control of F. occidentalis, with insecticides and inoculative releases of O. insidiosus on pepper crops under greenhouse production, during 2009-2010, a study of the seasonal fluctuation of the predator population, related to the pest and the temperature, was carried out at Mar del Plata Horticultural Belt. Besides, its distribution on the plant, and the effect of the releases plus the insecticides use on the pest population were determined. Also, the potential host spontaneous plants species for the predator, was determined in the greenhouse with release of Orius insidiosus and in the surrounding area. Integrated management with selective insecticides and O. insidiosus inoculative releases decreased populations of F. occidentalis. The highest density of thrips was recorded on flowers, indicating the preference of F. occidentalis for this part of the plant. Thrips control integrating the use of predator and insecticides was similar to that using only pesticide, with the advantage of the reduction on the number of chemical applications and the environmental negative impact. Portulaca oleracea L., Cynodon dactilon (L.) and Anoda cristana (L.) were the most abundant species as potential host for O. insidiosus. The use of natural enemies in the integrated pest control with low negative impact on non target organisms, present a promisorius cost/benefit relationship in the medium and long term run.Palabras clave – provistas por el repositorio digital
