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

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

The present research work was carried out to study the antioxidant effect of Ocimum sanctum in broilers exposed to high doses of gentamicin, which is common in poultry practice of Tamilnadu. Two hundred and seventy day old broiler chicks of either sex were randomly divided into nine treatment groups of 10 each with three replicates. Different doses of gentamicin (30 mg/kg&50 mg/kg) single intramuscular injection, different inclusion level of Ocimum sanctum crude extract (1%&2 %) in feed and their combinations were tested. The results of the study revealed that gentamicin treatment produced significant increase in the lipid peroxidation level, and significant decrease in the antioxidant enzymes viz. superoxide dismutase and glutathione peroxidase. Ocimum sanctum inclusion showed significant reversal in all the above parameters, which clearly supports its free radical scavenging property when co-administered with high doses of gentamicin.Keywords

The purpose of the study is to evaluate the immunomodulatory effect of Ocimum sanctum in broilers exposed to high dose of gentamicin which is common in poultry practice of Tamil Nadu. Two hundred and seventy day old broiler chicks of either sex were randomly divided into nine groups of 10 each with three replicates. Different doses of gentamicin (30mg/kg &50mg/kg) single intramuscular injection, different inclusion level of Ocimum sanctum crude extract (1 and 2 %) in feed and their combinations were tested. The results of the study revealed that gentamicin treatment produced significant reduction in serum total protein, albumin and globulin and numerical decrease in HI titre against Newcastle vaccine. The groups treated with Ocimum sanctum alone showed significant increase in all the above parameters. Dose dependent increase in all the parameters were noticed in the combination groups which clearly supports the immunoprotective effect of Ocimum sanctum.Keywords

The effect of supplementation of Withania somnifera extract on immunomodulatory response in broilers treated with high doses of enrofloxacin in poultry was investigated. Ninety day old broiler chicks of either sex were randomly divided into nine groups of 10 each. Enrofloxacin was administered at 30 and 40 mg/kg orally for seven days during the third week and W. somnifera crude extract was added in the feed at 1 and 2 % from second week onwards and the effect of their combinations was evaluated. The results of the study revealed that enrofloxacin treatment produced highly significant reduction in serum total protein, albumin and globulin and numerical decrease in HI titre against Newcastle vaccine. The groups treated with W. somnifera alone did not differ significantly from the control in all above parameters. Dose dependent increase in all the parameters were noticed in the combination groups which clearly supports the immunoprotective effect of W. somnifera.Keywords

Prickly acacia (Vachellia nilotica subsp. indica), a native multipurpose tree in India, is a weed of National significance, and a target for biological control in Australia. Based on plant genetic and climatic similarities, native range surveys for identifying potential biological control agents for prickly acacia were conducted in India during 2008-2011. In the survey leaf-feeding geometrid, Isturgia disputaria Guenee (syn. Tephrina pulinda), widespread in Tamil Nadu and Karnataka States, was prioritized as a potential biological control agent based on field host range, damage potential and no choice test on non target plant species. Though the field host range study exhibited that V. nilotica ssp. indica and V. nilotica ssp. tomentosa were the primary hosts for successful development of the insect, I. disputaria, replicated no - choice larval feeding and development tests conducted on cut foliage and live plants of nine non-target acacia test plant species in India revealed the larval feeding and development on three of the nine non-target acacia species, V. tortilis, V. planiferons and V. leucophloea in addition to the V. nilotica ssp. indica and V. nilotica ssp. tomentosa. However, the proportion of larvae developing into adults was higher on V. nilotica subsp. indica and V. nilotica subsp. tomentosa, with 90% and 80% of the larvae completing development, respectively. In contrast, the larval mortality was higher on V. tortilis (70%), V. leucophloea (90%) and V. planiferons (70%). The no-choice test results support the earlier host specificity test results of I. disputaria from Pakistan, Kenya and under quarantine in Australia. Contrasting results between field host range and host use pattern under no-choice conditions are discussed.Keywords

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
