Six years growth of performance trial of 32 clones of poplar growing under agro-climatic conditions of Tarai are reported. Object of the study was to locate clones other than G-3 and G-48 for commercial cultivation. Clone S7C4, S7C8, S7C15 and S7C20 were observed to be growing equally well and all of them are so far immune to leaf blight disease caused by Bipolaris maydis. Planting of intimate mixture clone G-3, G-48,S7C4, S7C8, S7C15 and S7C20 is advocated for commercial plantations.- Biology and Feeding Potential of Mallada boninensis (Okamoto), a Chrysopid Predator of White Fly Bemisia tabaci Gennadius

Biology and feeding potential of a chrysopid, Mallada boninensis Okamoto, recorded by us for the first time from Gujarat, were studied under laboratory conditions. The predator laid stalked eggs in groups usually of 11 to 20. The larvae with the habit of carrying trash on its back passed through three Instnrs, the durations of which were 4.11, 4.11 and 4.63 days at a constant temperature of 25.26 ± 2.2 °C and 59.90% RH. The short prepupal and pupal periods averaged 5 to 7 and 13.79 days respectively. The female was slightly bigger than male. The sex ratio of male:female was 1:1.5 with 81.40 per cent emergence of adults. Pre oviposition, oviposition and post-oviposition periods averaged 9.90 ± 1.60, 36.90 ± 4.41 and 18.00 ± 12.24 days respectively. The total number of eggs laid by the female averaged 431 ± 38.62 eggs. The average longevity of females and males were 64.8 ± 15.97 and 27.36 ± 8.03 days respectively. The larva consumed on an average 628.75 eggs of Corcyra cephalonica Stainton and 453 nymphs of white flies.Keywords

The Giant Metrewave Radio Telescope (GMRT) is today a frontline international facility for low-frequency radio astronomy, that has produced several exciting and important new results in the 15 years that it has been operational. To keep the GMRT competitive in the global arena in the future, a major upgrade of the observatory is nearing completion that will increase its sensitivity by up to three times and make it a more powerful and versatile facility. We describe the main goals of this upgrade, highlight the technical features and challenges, outline the science potential and update the current status of this venture.Keywords
