Abstract
The development time, survivoship and reproduction of Tuberolachnus salignus (Gmelin)( Lachninae: Lachnini) were
studied on Salix alba at fi ve constant temperatures (17.5°C, 20°C, 22.5°C, 25°C and 27.5°C ). The developmental time of immature stages ranged from 17.00 days at 17.5°C to 12.21 days at 25°C on Salix alba. The total percentage of survivorship of immature stages varied from 50% and 70% 17.5°C -20°C on S. alba. The largest r m valueoccurred with 0.2540 at 20°C on S. alba. The mean generation time of the population ranged from 13.595 days at 22.5°C to 19.60
days at 17.5°C on S. alba. The optimal temperature for Tuberolachnus salignus was 20°C.
