Teak Tectona grandis (Linnaeus), is the most preferred afforested species of Odisha as well as India. Among the total 42 species of insect pests recorded in seedlings of this sps., Hyblaea puera, Eutectona machaeralis, Lachnosterna serrata, five species of grass hoppers, Jassids, spittle bugs, Myllocerus beetle, Mealy bugs, aphid and, Tussock moth larvae were prominent in causing damage. The study further revealed that population of defoliator larvae was highest during 1st fortnight of June and continued upto 1st fortnight of December with peak appearance during 2nd fortnight of July, 2016 (11.23 larvae/seedling). Grass hopper population ranged from 2.34 to 3.27 per seedling and that of skeletoniser was ranged from 0.45 to 3.07 with peak availability during September 2nd fort night, 2016 (5.25 larvae/seedling). Aphid and other sucking pests made their appearance for a short period only but percentage plant mortality recorded due to white grub attack was ranged from minimum of 1.32% during September 1st fortnight to 30.85% during July 1st fortnight and the pest was appeared from June 1st fort night to September 1st fortnight only.
