Susceptibility of teak clones against defoliator and skeletonizer ab 68 EURO Morphological and biochemical variations in teak

Having pan-tropical distribution, the barbets are prominent group of birds belonging to family Capitonidea. Paucity of any detail information on ecology and biology of Asiatic barbets prompted the author to undertake an intensive study on life history of Indian barbets. It seemed also desirable to get an explanation how congeneric sympatric barbets coexisted successfully. Feeding impact of barbets on Coffee Plantations has also been discussed. Besides controlling termites and other harmful insects including coffee stem borer and teak defoliator, the barbets help in seed dispersal and cross-pollination of plants. Although still common at many places in the country, due to shrinkage of forests and avenue gardens, and poaching in certain areas, the population of barbets is declining. Therefore, barbets deserve due consideration in biodiversity conservation planning of the country for their sustainability.

Teak (Tectona grandisI is most important timber crop in Gujarat state of India. it is attacked by many insect-pests right from the nursery to the cutting stage. Amongst them, Teak defoliator (Hyblaea puera) and teak skeletonizer (Eutectona machaeralisz) are one of the most important insect-pests which remain active mostly during monsoon months. It is difficult to control these pests in old plantations so, selecting clones which are resistant orless suceptible is the most vital option of pest management. The research has highlighted the identification of teak clones on the basis of morphological, biochemical and nutritional characters which ulktimately proves R.H. Painter's theory of resistance and conforms non-preference and antibiosis type of resistance in the selected clones.
