Study was conducted on carnation (var. Master) during 2013 and 2014 under polyhouse. Infestation of Tetranychus ludeni Zacher was recorded. One species of predatory thrips viz. Scolothrips sexmaculatus Pergande was recorded in association with T. ludeni. Infestation of T. ludeni remained active throughout the year. Maximum population was recorded during June in both the years. Population was 13.2±1.24 and 14.4±1.57 mites/sample. Activity of S. sexmaculatus was recorded from June to August. Both species were recorded for the first time on this crop from North India. Population of T. ludeni and S. sexmaculatus was positively correlated with temperature whereas negative correlation with relative humidity. This study will be useful in bio control of phytophagous mites in IPM programme.
