Abstract

Oligonychus ununguis (Jacobi) is a pest of PICEA ABIES (L.) in Mazandaran providence. Its biology was studied in the labroatory and field conditions during 1992-94. Laboratory investigation carried out in three temperatures, 20°C±1, 25°C±1, 30°C±1 and 65±5 percent R.H. with 12 hours light. Duration of generation, oviposition period and longevity of mature mite at 20.C±1 were 21.49±1.17, 19.2±0.26 and 20.8±0.6 days and at 25°C±1 were 15.4±0.82, 15.9±0.32 and 17.2±0.67 days respectively-Average number of eggs laid in a generation and in a day at 20°C±1 were 23±1.28 and 1.6±0.26 and at 25°C±1 were 27±1.97 and 2.3±0.28 respectively upt. seven generations can develop in a year. At 30°c none of immature stages of 0- ununguis survived to maturity. Sex ratio (male / female) in laboratory condition was 1: 3,1. This species overwinters in the egg stage. The highest peak of the population was observed in August and September. Further to christmas tree and Abies spp., this pest was collected on Juniperus spp. as well.
