ResumoResult of the study showed that adults of D. pini have one generation in a year, adults emerge from cocoons in June when the air temperature reaches 15 °C and begin flying, larvae hatch from the eggs of those defoliate needles during August and September, and larvae fall down to soil to hibernate as mature larvae in cocoons after the air temperature declines below 10 °C in October. It was determined that effectiveness of 200 g preparate/ha dose of 25% diflubenzuron at 4th -5th instars of D. pini was 83.7% one week later than spraying, and 97.9% two weeks later. It was understood that specified insecticide at specified dose could be used against instars of D. pini. Keywords: Diprion pini, Biology, Diflubenzuron, Scots pine, Control date
