The study was undertaken to evaluate the antioxidant potential of Plumbago zeylanica L. in streptozotocin (STZ) diabetic rats. The ethanolic extract of ischolar_main of P. zeylanica L. at doses of 100 mg, 200 mg/kg p.o. for 21 days resulted in significant reduction in plasma TBARS and a significant elevation in plasma reduced glutathione (GSH), ascorbic acid. It is concluded that these results suggest that the ethanolic extract of ischolar_main of P. zeylanica L. possess a strong antioxidant effect in diabetic rats.Keywords

A detailed survey of aquatic macrophytes in Suchindram Theroor Birds Sanctuary, Kanyakumari district of Tamil Nadu was made during the period of two year (January-2011 to December-2012). A total of 46 species belonging to 24 families and 35 genera were identified, of these 3 are pteridophytes and 43 angiosperms. Further, the aquatic macrophytes classified in morphological group viz., floating (12), submerged anchored and floating leaved anchored (7) and emergent anchored (20). In Suchindram Perennial water source of the "Sanctuary serves as an important gateway for the migratory waterfowl.Keywords

Laboratory and field studies revealed that Aspidomorpha miliaris (Fabricius) larvae and adults are voracious feeders of Ipomoea carnea Jacq. leaves. The feeding rate increased as the larvae grew. First, second, third, fourth and fifth instar stages consumed 15, 20, 26, 32 and 47 mg leaf per larva per day, respectively. Female and male beetle consumed 42 and 36 mg leaf per day, respectively. The field study clearly indicated that 100 larvae per plant caused more than 97 per cent leaves damaged within 10 days. The feeding index increased gradually from the first day (45) to the last day (149) of the experiment.Keywords

The aim of the present study is to demonstrate the isolation and optimization bacteria with high cellulase activity from cow dung. The cellulolytic enzyme producing bacteria have been isolated from cow dung using Carboxymethyl cellulose clear zone (CMCZ) and Filter paper assay (FPA) techniques. Three isolates namely S1, S2, S3 have been isolated. According to the morphological and biochemical studies the isolates were primarily identified as Arthrobacter (S1), Ocrobacterium (S2), Flavobacterium (S3). Among the three isolates S2 showed maximal zone of enzyme utilization (1.2mm). Effect of incubation period, pH, temperature, carbon source was tested for cellulase productivity using Ocrobacterium (S2). Maximum growth was achieved at a time (Growth period) of 48 hours, highest cellulase activity was obtained after 72 hours of incubation by Filter paper assay. The maximum activity was achieved at 25°C and pH 5. When the bacterium was incubated at ammonium nitrate and Maltose it shows the increased enzyme activity.Keywords

Water hyacinth (Eichhornia crassipes) is an invasive aquatic macrophyte which creates several problems in irrigation system of rivers. To control their rapid distribution in water bodies the biological control method was carried by employing weevils Neochetina bruchi and Neochetina eichhorniae on river based field trial. The study demonstrates effectiveness of biocontrol weevil open field release on experimental site (Chittar river). When compared to first release in field, the weevil intensity was increased in numbers. Active scraping was observed in the leaves and decay spots were seen in the stems of weed. Both N. bruchi and N. eichhorniae (250 No) were introduced biyearly at experimental site for one year. During these two years of observation period, stunted growth and reduced population were observed in the study site. The study highlights importance of Neochetina spp. on the management of E. crassipes.Keywords
