    Semiochemical Receptors in Steatoda Grossa

    Get PDF
    Web building spiders are known to have poorly developed eyes, and acoustic organ for communication. Thus the only mechanism possible for mate identification is chemical communication. In nature female spider build a web and male wander around until find a terrestrial pheromones through female silk. Our preliminary experiments have confirmed absence of air borne pheromones. To ensure existence of semiochemicals series of experiment were carried out on a Therididae spider Steatoda grossa between combination of mature male with mature and immature female Steatoda. Male Steatoda when introduced on web of female showed vibration and female also showed vigorous vibration in response to male vibrations. Male responded to female web as soon as he landed on web confirming existence of some kind of identification factor on web which can be semiochemicals. The semiochemicals receptor have been detected on leg of Steatoda grossa through SEM. The receptor are located on the hair arranged in rows concentrating mainly on tarsal segment both the short and long hairs act as receptor for receiving stimulus. &nbsp

    Ipomoea aquatica, popularly known as Karmatta Bhajji, is a green leafy vegetable crop commonly consumed in rural areas of Chhattisgarh. It is supposed to possess several medicinal properties. The plant has rich iron content and is used traditionally to treat gastric and intestinal disorders. For phytopathological studies of this crop, survey and screening was done for two consecutive seasons in and around Raipur city, during 2011-2013. The diseased leaves were collected and brought to the laboratory for isolation. Chaetomium globosum, was isolated from the leaves showing a large number of white coloured small spots resulting in deformity of leaves. The crop is seriously damaged by C. globosum, locally named as Gomaha diseases resulting in an enoromous loss of crop. Fusarium oxysporum,was isolated from the leaves with brown spots. The cultures were maintained on Potato Dextrose Agar slants for further studies. &nbsp

    Herpetofaunal Diversity of Gandhisagar Wildlife Sanctuary, Madhya Pradesh

    Herpetofaunal communities of the Gandhisagar Wildlife Sanctuary (GWS) are diverse and poorly described. The paper gives an overview of the herpetofauna in the Gandhisagar Wildlife Sanctuary; based on the results of survey carried out in the July to August 2013 time period. We spent 17 field days to rapidly assess the present distribution and status of the herpetofaunastic species. Data collection will be carried out by using different method like visual encounter survey, call survey for frogs & toads; active night search and road kill survey. A total of 9 species of amphibians cover the one order Anura (4 families and 9 Genus) and 37 species of reptiles include the order Crocodylia (2 families 2 Genus), order Testudines (2 families 2 Genus), order Squamata included suborder sauria (4 families 7 Genus) and suborder serpents (6 families 20 Genus) have been recorded from the study area. The most diverse herpetofaunal community occurs in Gandhisagar Dam catchment area. &nbsp

    The Etiological Features and Treatment of Vitiligo: A Pilot Study Prospective to Indian Scenario

    Get PDF
    Despite studies of Vitiligo pathogenesis still evades its exact pathway, causes, a cast effective therapy challenge for Indian. Vitiligo is an acquired disorder of pigmentation, caused by decreased production of melanin as a result of dysfunction of melanocytes. In Indian tradition system plants medicine using for treatment of leucoderma but still no effective medicine cure the vitiligo. Indian studies of vitiligo find higher prevalence of vitiligo in Gujarat, Rajasthan, Madhya Pradesh, main possible causes are genetic, cellular, triggering, environmental effects, these gene polymorphism of candidate gene that are part of the immune system or part of melanocytes have both been associated with vitiligo and other autoimmune disorders. Environment Pollution like water, air and food pollution effects human health and increasing in villages and cities of India, environment pollution management and some diseases still gap in knowledge which are challenge for India. &nbsp

    EVAPO-Transpiration and Transpiration Rate of Some Tropical Tree Species

    Get PDF
    The present paper investigates transpiration and evapo- transpiration rate of tropical avenue tree species. The amount of water transpired per leaf was maximum in Azadirachta indica which was 2.88 followed by Eucalyptus camaldulensis 2.72 and minimum rate was found in Ficus religiosa i.e.1.48 gm/leaf/hrs. The rate of evapo-transpiration was also maximum in Eucalyptus camaldulensis followed by Azadirachta indica where is for other species they were relatively same. The present study confirms the reports that Eucalyptus.camaldulensis can transpire more than other Indian tree species but the study suggests that for cooling and shading purposes Eucalyptus camaldulensis is not a suitable tree. The lower rate of transpiration by Ficus benghalensis leaves is attributed to its xerophytes character. &nbsp

    Detection of Single Nucleotide Polymorphism by T-ARMS PCR of Cross Bred Cattle Karan Fries for A1, A2 Beta Casein Types

    “Detection of Single nucleotide Polymorphism by T-ARMS PCR of cross bred cattle Karan Fries for A1, A2 beta casein types” to distinguish between A1 and A2 type containing beta-casein and genotyping of hundred Karan Fries cross breed cattle. Casein is the main milk protein where it accounts for 80% of bovine milk protein and contains four fractions (alpha S1-CN, alpha S2-CN, beta-CN and k-CN). Beta casein contributes 25-35% of milk protein and many variants are reported (A1, A2, A3, B, C, D, E, F, G, H1, H2 and I) in different breeds of cattle. The beta casein variants A1 and A2 differs in the 67th amino acid position, the substitution of proline in A2 type with Histidine (in A1) is mainly due to a replacement of “C” nucleotide with “A” nucleotide in that corresponding nucleotide position. One hundred Karan Fries cross breed cattle were selected for genotyping of A1, A2 beta casein gene from the genomic DNA. The beta casein gene was amplified by Multiplex Tetra-Primer Amplification (T-ARMS-PCR). T-ARMS touchdown PCR and subsequent agarose gel electrophoresis could differentiate between the A1, A2 types of beta casein genes in these animals. The screening result showed three genotypes of animal in these 100 animals. The number of A2A2, A1A2 and A1A1 animals are 73, 19 and 8 respectively. The frequency of A2 and A1 alleles are 0.825 and 0.175 respectively

    Investigation of Natural Air Conditioning through Tropical Avenue Trees

    oai:ojs.pkp.sfu.ca:article/1The present study gives an idea on effect of trees on temperature, relative humidity and light intensity. There was an increase in temperature with corresponding increase in distance from the base of trees. There was 1-2º C difference found from 0-6 meter distance away from the base under different tree species. Whereas the relative humidity decreases with corresponding increase in distance .The difference in temperature away from the base of tree was more pronounced in F.benghalensis and F.religosa than E.camaldulensis. This was 8-9º C lower as compared to vegetation free ground. The study emphasizes the role of tree in controlling the micro-climate of holkar science college campus Indore. Maximum shade was observed under F.benghalensisand minimum at E. camaldulensis. The average light cut off was three times more by F.benghalensis than E. camaldulensis out of five test species . The Ficus species were found more effective than other . The study suggest plantation of Ficus species in urban areas to feel comfort in summer months
