Diversity, Biology and Control of Insect pests of teak Tectona grandis (Linnaeus) from western Maharashtra

ABSTRACT Teak Tectona grandis (Linnaeus) is an important component of western Ghats as a forest wood plant. It is attacked by 30 species of insect pests belonging to genera Myllocerus, Astycus, Trachypholis, Xyloborus, Cryphalus, Silvanus, Eugonius, Plateros, Psiloptera, Adelocera, Mesomorpha, Aspidomorpha, Aegosoma, Gelonaetha etc. of order Coleoptera and Hyblaea, Pyrausta, Eutectona of order Lepidoptera and Monophlebus and Aleurodicus of order Hemiptera. Their abundance, damage, life cycle and control were reported on teak from the fields of western Maharashtra. Encouragement to predators and parasitoids helped in pest control. Release of Trichogrmma spp. 1-1.5 lakhs/ha found effective for control of Lepidopterous pests. Spraying 0.15% carbaryl/ 0.1 % malathion/Azadirachtin was also found effective against teak pests.
