Aphis spiraecola Patch is a polyphagous aphid and is a major pest of citrus apple and Mexican aster. The diversity of its host range in India includes plants belonging to 278 species/subspecies under 68 plant families. Plants belonging to following families are highly infested: Asteraceae, Cucurbitaceae, Fabaceae, Lamiaceae, Malvaceae, Polygonaceae, Rosaceae, Rutaceae and Solanaceae.

The present study was carried out to determine the possible bioactive components of methanolic leaf extract of Magnolia nilagirica by using GC-MS analysis. The GC-MS analysis provides different peaks determining the presence of 55 compounds were identified from the leaf extract of M. nilagirica.

This study aimed to investigate the effect of Brilliant Blue and Dark Green food dyes on the Escherichia coli which is part of the intestinal flora.The food dye stock solution was prepared as 50 mg/ml with serum physiologic solution. Both of the food dyes were added in nutrient broth medium as 5, 2,5 and 1,25 mg/ml concentrations Design bacteria was inoculated inside of the dyes a 0.34 McFarland. After samples werewaitedin shaking incubator during 24 h, streaking was made to agar medium. In addition, RNA of control and sample groups were extracted forusing kits for molecular studying.

A total of 50 intestines of domestic chicken were collected in and around Cheyyar, Thiruvannamalai district from April 2014 to September 2014. The overall prevalence of parasitic infection was 91.54%. of this overall prevalence of 91.54%, 80.67% was infected with cestodes and 19.33% with nematodes. The collected tape worms (cetodes) were identified as Raillietina tetragona, R.echinobothridia, R.cesticillus, Cotugnia dionophora and Hymenolepis carioca) and nematodes were identified as Ascaridia galli and Heterakis gallinarum.

To understand the effect of Naphthalene balls on Brain and Muscle of coconut pest Rhinoceros beetle was selected. The biochemical parameters like Protein, Glucose and Glycogen on Brain and Muscle of both control and Naphthalene balls exposed Rhinoceros beetle have been carried out. The beetles were divided into two groups, one is control group (N=6). Another one is Experimental groups (N=6). The experimental group beetles were exposed with Naphthalene balls (l ball/beetle). After 96 hours of exposure the beetles in experimental group were totally dead.

This study was aimed to determine the prevalence of malaria infection among children aged 6 months-15 years and considered only Out-Patient children at EPU, Federal Medical Centre, Yola from the months of June to November 2015. Ethical Clearance and Informed Consent was obtained. Questionnaires were used to gather information on age, gender of children and parents/guardians sociodemographic characteristics. Malaria was screened using Thick and Thin blood film. The prevalence of malaria infection was 29.2%. The malaria species found was P.

The present study was undertaken to determine the glycemic index (GI) of ragi rotis incorporated with curry leaf powder. Two ragi varieties viz. SRICHAITHANYA (brown ragi) and HIMAJA (white ragi) were selected. Ragi rotis were evaluated for glycemic response. The glycemic index of rotis ranged from 56.2 to 67.3. White ragi roti had the highest GI with 67.3 followed by White ragi roti incorporated with curry leaf powder with 62.5. Brown ragi roti had GI Value of 61.0 and the least was for Brown ragi roti incorporated with curry leaf powder with 56.2.

Biomass of mangrove seedlings serves as proxy to environmental health. Accurate assessment of mangrove seedling biomass at the site- scale is lacking, especially in the World Heritage Site of Indian Sundarbans. Sonneratia apetala (locally known as keora) is a common fresh water loving mangrove species. This study assessed the biomass of the vegetative parts (leaf, stem and root) of S. apetala seedlings from 18 sampling stations distributed in the western, central and eastern sectors of Indian Sundarbans with contrasting salinity profile.

Tomato (Solanum lycopersicum) is known to be associated with a reduced risk of developing a certain chronic diseases and cancers due to the presence of lycopene, a bioactive carotenoid. The objective of this study was to determine the antioxidant activity in tomato powder and TP extrudate (Tomato powder incorporated extrudate). The results of present study showed that flavonoid content in tomato powder incorporated extrudate of IC50 value in control extrudate (22.28±0.01) was more when compare to the TP extrudates (15.51±0.01).

The composition of minerals and vitamin A of Ziziphus mauritiana Lam. ; Detarium microcarpum (Guill. & Perr.); Balanites aegyptiaca (L.) Del.; Vitellaria paradoxa Gaertn. F.; Tamarindus indica L. ; Hyphaene thebaïca Mart. ; Borassus aethiopum Mart. ; Adansonia digitata L. ; Vitex donania Sweet. ; Parkia biglobosa (Jacq.) Benth. was studied and quantified in tree Departments of Chad. The minerals were determined by spectrometry and photometry and vitamin A was determined by HPLC.
