The Relationship between the Damage Rate and Adult Population of Cherry Slugworm, Caliroa cerasi (L.) (Hymenoptera: Tenthredinidae)

This study aimed to reveal the relationship between the damage rate and the adult population of Cherry slugworm, Caliroa cerasi (L.) (Hymenoptera: Tenthredinidae), which is an important pest in sour cherry cultivation. Adult and pre-adult periods of the Cherry slugworm were the main materials used in this study. In addition, yellow sticky traps to attract adults, stereomicroscopes, and lancets were used. Studies were conducted in 11 orchards, including 6 orchards in Çayırlı district and 5 orchards in Central Erzincan district. The study results showed that there was a relationship between the damage rate of the Cherry slugworm and the adult population. In both years there was a very high and positive correlation (r = 0.99 - 0.943*, p = 0.01) and a linear relationship between mean damage rate and total adult density.
