Twenty two conventional insecticides were tested as direct spray against adult beetles of Calopepla leayana. This is a serious pest of Gmelina arborea plantations and occurs all along the tract of its host plant. The relative effectiveness of these insecticides was in order of Formothion> Monocrotophos> Quinalphos> Chlordimeform> gamma-BHC> Malathion + Fenitrothion > Toxaphene> Malathion> Dichlorvos (Nuvan) > Pyrethrum> Klofos > Endosulfan > Bromophos-ethyl > Fenitrothion > Dieldrin> D.D.T. > Aldrin> Chlordane> Dichlorvos (DDVP)> Methyl parathion.- Laboratory Bioassay of some Insecticides as Contact Poison against Third Instar Larvae of Glyphodes pyloalis Walker (Lepidoptera : Pyralidae)

The nineteen conventional insecticides were tested as contact poison against third instar larvae of Glyphodes pyloalis in laboratory. The descending order of toxicity of the insecticides was : chlordimeform> formotbion > quinalphos >monocrotophos> toxaphene> carbaryl> fenitrothion> malathion (premium grade) :> methyl parathion > endosulfan > malathion + fenitrotbion > leptophos :> klofos :>dichlorvos > endosulfan > DDT > dimethoate> pyretbrum>chlordane>gamma-BHC. Monocrotophos, formothion and chlordimeform are 27 to 32 times more toxic than DDT. Relative resistance to these insecticides of Glyphodes pyloalis than Selepa celtis is also discussed.- Aristobia horridula Hope (Coleoptera: Lamidae) a new pest of Shisham (Dalbergia sissoo Roxb.) in West Bengal

>>Twenty-one insecticides were tested as contact poisons against the 3rd instar larvae of Selepa celtis infesting Morus alba. Monocrotophos, chlordimeform, quinalphos and anthio were more toxic than DDT, while ambithion. Dimetheate and endrin were less toxic than DDT. The rest of the 14 insecticides were in the follwing order of effectiveness : carbaryl > endosulfan > pyrethrum > gamma-BHC > dichlorvos > toxaphene > leptophos > malathion > klofos > fenitrothion > dieldrin > aldrin > eythion > DDT.- Repellency Effect of Essentials Oils Using K and D Module against Aedes aegypti, Vector of Dengue and Chikungunya

Essential oils are natural volatile substances from plants and they are used as protective measure against blood-sucking insects. The objective of the study was to determine the effective repellency of 23 essential oils at various doses against female mosquitoes Aedes aegypti under laboratory conditions using K&D module and to identify chemical constituents of the oils by Gas Chromatography/Mass Spectrometry (GC/MS). The results showed that litsea oil exhibited effective mean percentage repellency of 43%, 86%, 93% and 100% at 0.01%, 0.1%, 1.0% and 10% concentration, respectively with the median effective dose (ED50 ) of 0.012 (95% CI= 0.003-0.028). At 20% concentration, litsea oil showed 83% repellency upto 2 hr and the dominant component of litsea oil was identified as Zcitral by GC/MS. The studies indicate that these oils could be used in the preparation of herbal mosquito repellents which are safe to human beings.Keywords

Ixora coccinea L. (Rubiaceae) is a traditional herbal medicine for various ailments like cutaneous wounds, infection, hypertension, menstrual irregularities, sprain, chronic ulcer and other skin diseases. The present study investigated the anti-inflammatory effects of I. coccinea leaves methanol extract (IxME) on RAW 246.7 macrophage and its effect on Prostagladins E2 (PGE2), Nitric Oxide (NO) and pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β) production. The experimental findings revealed that IxME treatment inhibited the Cyclooxygenase 2 (COX-2) mediated PGE2 and Nitric Oxide Synthsae (NOS) catalyzed NO production in LPS-treated RAW 246.7 macrophages in a dose dependent manner. On the other hand, production of pro-inflammatory cytokines including TNF-α, IL-6 and IL-1β was significantly decreased as compared to negative control LPS-treated RAW 246.7 macrophages. The findings data coincides and correlated the in vitro anti-inflammatory activity of I. coccinea with previous reports of in vivo anti-inflammatory property.Keywords

The present study is an evaluation of ground and surface water quality at Balipara, North Brahmaputra river basin, Sonitpur district, Assam, India using multivariate statistical methods. The results show high concentration of Fe, Mn, Pb and Cr in groundwater. Arsenic was observed in both ground and surface water. In the surface water, nitrate content was also found to be high. Ward's method was used for hierarchical agglomerative cluster analysis. A close relationship between electrical conductivity (EC) and total dissolved solids (TDS) was established by the smallest proximity distance between these parameters. Group 1 comprised of TDS, EC, total alkalinity (TA), F, Ca, Pb, Cr and Cl based on proximity distances. Group 2 consisted of Fe, Mn, As and Group 3 of TH, Mg, pH, Zn, SO4 and NO3 in groundwater. In surface water, Group 1 comprised of TDS, EC, SO4, NO3, Cl, Zn, pH and Ca. Group 2 accounted for Mg and F and Group 3 for Fe, Mn, TA, Pb, As and Cr. The interrelationships between the contaminants depicted by cluster analysis, categorize the contamination levels. Factor analyses were applied for understanding the interrelationships between the variables and for identifying probable source components. Six factors justifying 83.64% of the total variance in groundwater and five factors describing 81.92% of the total variance in surface water were found responsible for variation in the data structure. The relative contribution of all the water- quality parameters was best explained by discriminant analysis.Keywords
