Onion thrips,Thrips tabaci Lindeman, is the most important impediment for production and exports ornamental plants in Iran. This pest damage seriously to cut flowers especially Carnation, Gladiolus, Chrysanthemum and Tuberose. Without Correct pest management and rapidly spray against the onion thrips accused to increase production cost, environmental pollution, producers and consumers poisoning. Experiments accomplished to comparison different methods to control of the thrips in Ornamental Plants National Research Station of Mahallat in greenhouse conditions in 2002 and 2003 years. Results showed integrated method with 90.22% thrips mortality was the most effective method to control of the thrips. Then extension and research design accomplished for above purposes in six greenhouse of Mahallat City that consisted control, spray and integrated control (spray then release of 3 until 4 predator bug per plant).The experiments were randomized complete blocked design with 6 treatments and 10 replications (10 rows of Carnation). Results showed the number of population of the thrips per flower were 6.8-7.7 in control greenhouse, 1.1-3.1 in spray greenhouse and 0.25-0.4 in integrated control greenhouse respectively. Treatments were significant in 99% probabilities. So with greenhouse correct management and to application of integrated control to control of the thrips on carnation flower well be able to produce flower with at least poison residue and at least the thrips damage symptom.
