Utilization of induced defence in forest pest management has the potential to increase total forest productivity provided the factors which influence the induced resistance response in forest trees are understood. Of the many possible mechanisms that could be responsible for protecting trees from herbivores is induced plant chemical defences. Induced response vary spatially that they can remain localized or can spread from a damaged plant to an undamaged plant. Manipulation of induced plant defence by mechanical defoliation and in the regulation and stimulation of natural enemies influenced by chemical signals emitted from infested plants are also discussed.- Antifeedant and Antifungal Compounds from Dirca palustris

Wide range of insect pests and fungal pathogens attack seedlings, saplings and trees of economic important viz., Teak, Neem, Bamboo, Eucalyptus and Casuarina. The study highlights those solvent extracts of D. palustris (leather plant) responsible for antifeedant activity against Teak defoliator Hyblaea puera and skeletonizer Eutectona machaeralis. It was tested for fungal toxicity against some forest tree pathogens also.- New Record of Blister Beetle on Neem-chameli : its Interaction with Flavonoid Pigments

The activity of biological control agents like predators, parasitoids etc. attacking pests can depend upon the properties of the host on which it is developed. Therefore, the reproductive behavioural strategy of host eggs, Corcyra cephalonica were tried with different nutritive medium in order to produce the active and viable parasitoids like trichogrammatids, chrysopids etc against pest resurgence especially forest insect groups.- Record of Thosea bipartita (Limacodidae: Lepidoptera) on Azadirachta indica (neem) from Jodhpur, India

An experiment was conducted to study the efficacy of neem seed oil and some conventional against the babul whitefly Acadaleyrodes rachipora on Acacia senegal. The results revealed that neem seed oil at 0.5, 0.3 and even at 0.1 % concentrations were very active and suppressed the development of the whitefly significantly while monocrotophos and endosulfan were not effective to suppress this whitefly.- Identification and Characterization of whey Protein, Casein Micelles and Fat Globules in Cow Milk

Pasteurized cow milk (whole milk) was used in the present study and also fat was removed from the whole milk to obtain skimmed milk. Whey is the liquid remaining after milk has been curded and strained during the manufacture of cheese. The sample was filtered using a Whatman filter paper to separate the precipitate. The filtrate thus obtained is called whey (devoid of casein and fat). The micrographs of whole milk, skimmed milk and whey were obtained using an inverted phase contrast microscopy. The hydrodynamic size and zeta potential of the samples were obtained using Dynamic light scattering technique. Atomic force microscopy was also performed to understand the surface morphology of whole milk, skimmed milk and whey on mica substrate.Keywords

In recent years, synthesis and characterization of Ag-based materials has become an active area of research due to its application in medical area for having antimicrobial properties useful for prosthetic replacement. Pure HydroxyAPatite (HAP) and 1.5wt% Ag-doped HydroxyAPatite (AgHAP) were prepared by sol-gel process and characterized. Ca(NO3)2.4H2O was used as source of Ca precursor, P2O5 was used as a source of P precursor, and AgNO3 has been used as a source of Ag precursor. Pellets of HAP and AgHAP were made after precipitates were consolidated, dried in oven, grounded and sintered in a muffle furnace. Functional groups were determined using FTIR, and compound formations were investigated using XRD. Microstructural analysis was done using SEM and AFM. Wettability was studied using OCA in distilled water, and corrosion resistance and impedance analyses were carried out using ECA in Ringer solution. It was observed from AFM and XRD that grain size decreased from 7.05 μm to 1.25 μm. Improvement in corrosion resistance was observed in AgHAP. Wettability studies showed that AgHAP is more hydrophilic in comparison with pure HAP. A correlation between microstructures and properties of hydroxyapetites are discussed in this paper.Keywords
