The bark beetles (Coleoptera: Curculionidae: Scolytinae) are widely recognized as one of the most damaging groups of forest pests. The present article documents the insect predators associated with bark beetles infesting blue pine, Pinus wallichiana A. B. Jacks (Pinaceae), in Kashmir Himalaya. Three species of bark beetles, such as Ips stebbingi Strohmeyer, 1908, Polygraphus major Stebbing, 1903, and Pityogenes scitus Blandford, 1893, are here reported as preyed upon by the following four species of predatory beetles: Thanasimus himalayensis Stebbing, 1914 (Cleridae), Niponius canalicollis Lewis, 1901 (Histeridae), Platysoma rimarium Erichson, 1834 (Histeridae), and Corticeus flavipennis Motschulsky, 1859 (Tenebrionidae). Brief diagnoses with photographs of all the pests and their predators have been provided. P. rimarium is also redescribed. A significant number of predators observed in the galleries of bark beetles and on the infested host material support that predators play a major role in the regulation of bark beetle populations and, therefore, has great relevance to ecological pest management strategies in the forests.

Five species of pteromalid wasps (Cheiropachus quadrum [Fabricius, 1787], Macromesus harithus Narendran, 2001, Metacolus sinicus Yang, 1996, M. parasinicus sp. nov., and Roptrocerus mirus [Walker, 1834]) reared from branch cuttings of Pinus wallichiana A. B. Jackson (Pinaceae) infested with three species of bark beetles (Ips stebbingi Strohmeyer, 1908, Polygraphus major Stebbing, 1902, and Pityogenes scitus Blandford, 1893) are reported from Kashmir, India. A new species of Metacolus from Kashmir is described and illustrated. A key for the identification of the six known species of Metacolus Förster, 1856 is given. Roptrocerus mirus and M. sinicus are reported for the first time from the Indian subcontinent. New host–parasite associations are reported for three species of pteromalid wasps.
