Studies were conducted at the Indian Institute of Horticultural Research, Bangalore, and Central Horticultural Experiment Station, Bhubaneshwar, India, to evaluate trap design, quantity of pheromone loading and dispensers for attracting brinjal shoot and fruit borer, Leucinodes orbonalis Guenee (Lepidoptera: Pyralidae) using indigenously synthesized pheromone lure [synthesized by Indian Institute of Chemical Technology (IICT), Hyderabad], during 2003 and 2004. A water trap consisting of plastic container (20 cm dia. and 7.5 cm depth) with a facility to place the pheromone septum was designed. Pheromone load of 4 mg in both water trap and Pest Control India (PCI®) delta trap was observed to catch higher number of male moths compared to dispensers with lesser loading. When trap designs were compared, water trap with pheromone lure was observed to attract higher number of males than Pest Control India (PCI®) delta trap. Among the different pheromone dispensers tested, rubber septum was superior to plastic vial or plastic septum. Rubber septum supplied by Bio Pest Management® captured significantly higher number of moths compared to rubber and plastic septum supplied by difTerent firms. A comparison of IICT synthesized lures along with some commercially available lures indicated that Bio Pest Management® lure dispensed in rubber outperformed PCI® and IICT lures.Keywords

A survey was undertaken to document species composition of thrips on grape foliage, inflorescence and different stages of berry development such as mustard size (2 mm), sorghum size (4 mm), pea size (8 mm) and beyond pea size (> 8 mm) berries at Bijapur in Karnataka and Sangli in Maharashtra during January 2005 to January 2006. Cultivars sampled were Thomson Seedless, Sonaka, Sharad Seedless, Tas-A-Ganesh, 2A and B5 clones of Thomson seedless. Scirtothrips dorsalis Hood constituted over 90% of total thrips sampled from new flushes, inflorescence and berries in different stages during January, February, March and December 2005 at Bijapur followed by Thrips palmi Karny (1- 4.3%); Thrips hawaiiensis (Morgan) a hitherto unknown thrips species on grape dominated inflorescence (98.0%) on cv. Sonaka during December 2005 in the same area. Similar trend was observed in the vineyards of Sangli. Number of thrips, which was more on inflorescence declined as the berry matured. Least number of thrips was observed on berries > pea size. As recorded in Bijapur, T. hawaiiensis was dominant species on inflorescence of 2A (98.6%) and B5 (99.4%) clones of Thompson seedless. In other cultivars S. dorsalis was dominant that formed 92.8 -100% of total thrips collected. Thrips palmi constituted 0.8-1.7% of thrips collected from different parts of grape vine. Other unidentified thrips constituted 0.9-7.2%.Keywords
