ABSTRACT
Blue pine (Pinus wallichiana) locally known as kail is a beautiful fast growing pine, naturally found between 1200 m and 3000 m elevation in the hills of Pakistan and Azad Kashmir. The tree which was well known for its resistance against insect pests has fallen pray to lepidopterous pests in the very recent years. In 1980 a new giant defoliator, Biston regalis Moore (Geometridae: Lepidoptera) attacked kail forests, denuding large patches of hill tops in beautiful tourist resorts of Murree in the Punjab (Pakistan) and Loon Bagla and Danna of Azad Kashmir. In 1984 microlepidopterous leaf stitchers caused defoliation of kail trees in patches in the Galis Forest Division at Chatri R. near Thandiani, Bagan near Nathiagali and Darwaza near Kuzagali in Hazara, N.W.F.P.
