Abstract

Thrips tabaci, is one of the most important pests of onions, which due to its high fertility rate and high growth rate, quickly becomes resistant to pesticides, Therefore, Integrated Pest Management and cultural methods is the best way to control this pest and prevent the emergence of resistant populations. This research was aimed to use nutrient elements and irrigation intervals in reduction of population and Damage of onion thrips and was conducted as a factorial experiment arranged in completely randomized design. Treatments including irrigation intervals (4, 8 and 12 days) and nutrients (silicon, potassium, Calcium and no fertilizer) were applied at four-leaf stage of onion, Zargan cultivar. The results revealed that the use of different fertilizers and irrigation intervals had a significant effect on the population and the amount of Damage of onion thrips. The lowest mean number of T. tabaci was observed in the Silica fertilizer treatment (13. 37) and the highest mean number was observed in control plants (without fertilizer) with an average of 40. 68 thrips per plant. Also, the highest Damage to the leaf surface was observed in the 12-day irrigation interval (with an average of 42. 7%) and the lowest Damage was observed in the 4-day irrigation interval and Silica fertilizer treatment with an average of 27. 5%. According to our results, managing the irrigation intervals and types of nutrients, especially Silica and Calcium, which strengthen plant tissues, can reduce the onion thrips population and its Damage.
