Sustainable Hypoglycemic Action of Neem Oil on Male Rabbits and Its Impact on Some Glucose Regulating Hormones

A field study was conducted to evaluate the efficiency of four microbial insecticides viz. Beauveria bassiana; HaNPV (Helicoverpa armigera Nuclear Polyhedrosis virus); (Bacillus thuringiensisvar.kurstaki 2 gm/L); HaNPV+Bt; neem oil; neem cake and D.D.V.P EC 76% @0.05% at Research Farm SHIATS,Allahabad during rabi season of 2011-2012. The experiment was laid out in randomized block design with seven treatment and replicated thrice. The observation larval populations of H. armigera were recorded one day before treatment was recorded at 3,7, and 10 days after treatments. The larva population of H. armigera appeared in the third week of February (8 the Standard week) and reached its peak of 14.65 larvae in first week of April and decline rapidly with maturation of crop. There was only one peak in the larval population observation in the 1st week. Bacillus thuringiensis was the most effective chemical by D.D.V.P.76%@0.05% . Among the microbial insecticides. HaNPV ,was the most effective followed by HaNPV+Bt and neem cake . The combination treatments were less effective than the individual treatment neem oil and B. bassiana were the least effective treatment in reducing the larval population of Heliverpa armigera.

Aesthetic Appearance

Background: Mould growth on coated wood products during shipment is the foremost apprehension for most of the wood industries in India. Well finished wood products tend to get deposited by staining moulds superficially in high humidity conditions during shipment. Though wood disfiguring fungi (stain moulds) normally have no significant effect on the mechanical properties of timber, they only affect the aesthetic appearance of the material without destructing the wood cell wall. This causes a huge economic loss to the manufacturer due to disfigurement of the appearance of wood products. Methods: The aim of this work is to test and enhance antimicrobial property of Nitrocellulose lacquer wood finish to prevent mould deposition on coated wood products. The work was carried out to screen and evaluate the antimicrobial activity of commercial Nitrocellulose lacquer. Several patents regarding antimicrobial activity of nano metal oxides have been visited. In order to enhance the mould resistance of this coating, its combinations with neem oil and ZnO nanoparticles were prepared and tested against the growth of staining moulds: Aspergillus niger and Penicillium sp. on the wood substrate of Melia dubia. The study was carried out for 500 hours under favorable conditions (Temperature and Relative Humidity (RH)) for the mould growth. The growth was analysed on the basis of surface area affected by stain moulds on coated wood samples. Results: The growth analysis data inferred that the ZnO nanoparticles had significant effect against the growth of stain moulds. The presence of ZnO nanoparticles increased the mould growth resistance of Nitrocellulose lacquer coating to a great extent compared to the ability of neem oil for the same. This finding demonstrates the potential use of nano ZnO for increasing the effectiveness of NC lacquer against mould growth without hampering its other properties. Conclusion: 1 % nano ZnO concentration in Nitrocellulose lacquer wood coating increased its efficacy against staining mould growth by 95 %.

Mycelia Growth

The enormous use of metallic wood preservatives has caused destructive impact on environment as well as human health. Therefore realizing the urgency of switching to Environment friendly options such as natural oils are being tested for their antimicrobial properties. The present study aimed at investigating potential of Neem oil against the growth ofdecaying fungi. The ability of Neem oil to inhibit mycelia growth of Schizophyllum commune, Fusarium oxysporum, Fusarium proliferatum, Coniophora puteana and Alternaria alternata was tested at different concentrations of 0.25, 0.50, 0.75, 1.0, 2.0, 4.0, 6.0, 8.0 and 10%. Results of the study revealed Neem oil concentrations above 2% were significantly inhibitory to all the tested fungi.
