Prevalence of Eomenacanthus stramineus (Insecta, Phthiraptera, Amblycera, Menoponidae) on poultry birds (Gallus gallus F. Domesticus) of Jaunpur
Get PDFA total of 1,020 poultry birds belonging to twelve different localities of Jaunpur district were surveyed during May 2006 to April 2007 to record the prevalence rate of Eomenacanthus stramineus. Prevalence of E. stramineus was noted more or less similar in both the sexes (Male – 38% and Female – 39%). Maximum birds bore very low infestation (32%) while only 7% birds exhibited very heavily infestation. Host sex, feather colour and locality had negligible effect on prevalence rate. However, prevalence rate remained slightly higher on birds with poor plumage/health. Significant positive correlation existed between mean monthly prevalence rate and mean monthly temperature as well as photoperiod. Mean monthly incidence rate were recorded higher during summer (May and June) as compared to winter months
Prevalence of Pediculus humanus capitis in a school of low socio-economy area in Rampur (U.P), India
Get PDFThe prevalence of head louse Pediculus humanus capitis on the school children of a low socio-economy area of Rampur, India was found to be 56% (n=300). Female children appeared lousier. However, the hygienic condition and their density appeared to have negligible effect on head louse
Influence of arbuscular mycorrhizal fungi and Trichoderma viride on growth performance of Salvia officinalis Linn.
Get PDFSalvia officinalis (Sage) is a popular kitchen herb, member of mint (Lamiaceae) family has been cultivated for its wide range of medicinal values. Arbuscular mycorrhizae (AM) are beneficial symbionts for plant growth and development and offer a viable replacement of high input agricultural technology employed for production of environmentally hazardous fertilizers. Therefore, the present study was focused to analyze the effect of two AM fungi (Acalospora laevis and Glomus mosseae) along with Trichoderma viride, alone and in combination, on different growth parameters of S.officinalis in a green house pot experiment with sterilized soil. AM inoculum and T.viride showed significant increase of different growth parameters after 45 and 90 days of inoculation. Among all treatments, dual combination of A.laevis plus T.viride was most effective in increasing shoot length, leaf area, root length, root weight, AM spore number and percent root colonization. Moreover, maximum increase in shoot biomass was found in plant treated with T.viride
Imaging and visualising nanometre scale surface geometry of a crystalline mineral (SiO2) in monochromatic spectra
Get PDFDigital microphotography and image analysis is considered as an important tool in sedimentology and mineralogy for the assessment of physical characteristics at micro and nano level. In this paper the present authors attempted to apply digital imaging technique to visualise the surface geometry of Quartz at nanometre scale. For that purpose a quartz specimen was picked up from microphotography of a thick section of sediment layer and 1?m X 1 ?m base image was prepared for digital operation with sophisticated software. Reflectance capacity of the particle has been considered to measure the surface condition. An automated contour plotting was done from the base image. Surface condition was also analysed by reflective radiance measurement. Four images based on greyscale, black body law, pseudo colour composition and landscape were prepared for detailed assessment of quartz nanomorphology. A 3D image was also consulted for understanding the geometry of the surface of quartz
Feed stock crop options, crop research and development strategy for bioenergy production in India
Get PDFSoaring prices of fossil-fuels and environmental pollution associated with their use, has resulted in increased interest in the production and use of bio-energy in India. Government of India has made policies to promote the production and use of bio-fuels which have triggered public and private investments in bio-fuel feed stock crop research and development and bio-fuel production. In this paper, efforts have been made to review and discuss various feed stock crop options and crop research and development interventions required to generate feed-stocksto produce required volume of bio-energy to meet projected demand without compromising food/fodder security and potential benefits of bio-fuels in reducing environment pollution and contributing to the energy security in India
Seasonal variation in phytoplankton of Tadoba lake, Tadoba Andhari Tiger Reserve (TATR), Distt. Chandrapur (MS), India
Get PDFTadoba lake is the major lake in Tadoba Andhari Tiger Reservoir (TATR) in the Chandrapur district, in eastern Maharashtra which represent a unique habitat for wildlife in central India and oldest National Park of the state. The lake is free from human activities. The present investigation was carried out to evaluate the population of planktonic algae of the lake from June-2006 to May-2007. The study of phytoplanktonic diversity revealed the presence of 35 species belonging to four major groups, Chlorophyceae, Bacillariophyceae, Myxophyceae and Euglenophyceae among which Bacillariophyceae was dominant. The rich floral diversity indicates high productive nature of pond

WQI range falls from poor (70.45, December; 73.55, October; 74.4, November and 74.56, September/ 74.52, January and 75.36, September), very poor(82.54, February; 89.25, May; 80.76, August and 78.86, January/ 80.89, February; 98.25, April; 80.03, June; 82.26, July; 86.55, October and 83.03, November) to unfit (100.44, June; 101.9, July; 103.86, April and 119.5, March/ 103.73, May; 108.28, March; 122.56, August and 103.72, December). Comparison of range of various water quality parameters of Surinsar lake water, with national and international standards has also revealed that most of these parameters are beyond permissible limits. This clearly indicates the unsuitability of raw water, generally consumed by local inhabitants, for human consumption

Enhancing seedling production of black velvet tamarind (Dialium guineense Willd) 1
Get PDFThe present investigation was conducted to enhance seedling production of Black Velvet Tamarind (Dialium guineense). Three different types (sets) of experiments were designed. The results showed no sprouting of the stem cuttings in the first type of experiment ( stem cuttings treated with Naphthalene Acetic Acid (NAA) and coconut milk). The second type of experiment (seeds subjected to some pre-sowing treatments using NAA, coconut milk, manual scarification and seeds soaked in water for 24 hrs) showed highly significant treatment effects for seed treatments and days after planting, DAP (p < 0.001), while time or duration of treatment was not significant. There were highly significant interaction effects for Treatment duration x Seed treatments and Treatment duration x Days after planting (DAP). Mean percentage germination was best at 2000ppm NAA (43.85%), but was not significantly different from1000ppm, (40.28%), water soaked (40.28%) and manual scarification (38.88%). Lower germination rates were observed for 500ppm (34.72%), normal or untreated seeds (30.75%), and coconut milk (28.38%). There were highly significant treatment effects (p < 0.001) between the control (normal seeds) with 11.2% mean germination, cold treatment (stratification), 21.1% and manual scarification 33.7%. DAP was also highly significant with the highest mean germination of 34.1% at 56DAP. Treatments x DAP was highly significant (p < 0.01) in the third experiment (stratification, a cold temperature pre-sowing treatment). Soaking seeds for 24 hrs before planting was adjudged the best treatment for enhancing seedling production in Dialium guineense in this study. It was the easiest and cheapest of all other treatments considered
Essential phospholipids protection against mercury uptake and histopathological changes in the intestine of fish, Oreochromis mossambicus (Trewavas)
Get PDFHistochemical examination of fingerlings and adults of freshwater teleost Oreochromis mossambicus (Trewavas) exposed to sublethal concentration of HgCl2 (0.15 mg/l) for 30 days revealed considerable uptake of mercury by their respective intestines. Simultaneous co-administration of Essential phospholipids (EPL) along with food to the fishes, significantly supressed mercury uptake by the intestinal tissues, except the goblet cells which were still loaded with Hg in both stages. Due to accumulated mercury visible histopathological damage was seen in muscle layers, lamina propria and basement membrane of columnar cells. No noticeable damage in intestine was seen, when EPL was simultaneously fed to fishes along with HgCl2 exposure. Results suggest that EPL plays prophylactic role against metal uptake and structural damage in fish intestine exposed to inorganic mercury
