The use of natural plants products that reduce mosquito population can provide many associated benefits that limit pesticides environmental impact due to shorter latency and may be useful in preventing development of resistance. The larval mortality was observed at 24hrs and 48hrs of time exposure. LC50 value was calculated. Microscopic slides were prepared from live larvae and microscopic photography were done for the prepared slides and studied for visible changes. Dose mortality test observation showed the intensity of activity in a descending order as Moringa oleifera Lam. > Catharanthus roseus Linn. > Lantana camara L.> Thyme vulgaris L. From this result we can conclude that more effective plant extracts results in more clumped/fused chromosomes. Effects of plant extract induced on polytene chromosome most frequently were structural in nature.

Birds contribute indirectly to human welfare as majority of them feed on insects and rodents and some are efficient scavengers. Poultry forming is a leading profession which provides nutritive food products for human consumption. However, these valuable resources can be infected with a wide range of blood parasites which may affect their survival and existence. In this study, the impact of Haemoproteus, an intracellular sporozoan parasite of the common pigeon. Columba livia on some heamatological parameters (Hb% and TEC) was examined. The investigations were conducted in two groups of Columba livia. Group A: Control, Group B, Heamoproteus infected. The Hb values (13.410.17gm/100ml) in Group A decline to (10.8±0.37 gm/100ml) in Group B. TEC in Group B also declined to 1.620.05x106/Cmm from the normal values of 2.19±0.02x10/Cmm in Group A. The fall in Hb% was 18.97%. and that in TEC was 24.2%. The values of TEC are more affected (24.2 %) as compared to Hb (18.97%). Being an intracellu...

The resistance of pesticide by the pest is an important matter of concern .The pesticide of plant origin having nontoxic biodegradable and environmental friendly qualities. The frequent spraying of toxic chemicals developing resistance to the pesticide. Leaf powder of the plants like Argimone Mexicana and Calotropis procera is prepared, Different doses of these plant extracts is given to the Fourth instar stages of Helicoverpa armigera through feeding methods, To find their efficacy the experimental findings will be put under analysis using various perameters. The effect on paritrophic membrane is also studied.

World’s 40% population is at risk of dengue which is transmitted by Aedes aegypti and Aedes albopictus. Many measures for Aedes control are taken but still mosquitoes find their way to breed and transmit diseases. Insecticide use is been considered effective for emergency mosquito control and many more insecticides are under trials but mosquitoes usually develop resistance against these chemical formulations. In recent years green synthesized nanoparticles are proved to be potential targets against larvae, pupa and adult form of mosquito. This paper reviews the various developed nanoparticles during and their potentiality in Aedes control. Larvicidal activity of nanoparticles is given for I instars, II instars, III instars, IV instars and pupa differently. Nanoparticles are fabricated from many medicinal plants extract and some are very much effective against mosquito control. This is an eco friendly approach for mosquito control with low risk of resistance development.

Microbiological analysis is the useful way to assess the safety and quality of food .Substantial number of micro-organisms suggest a general lack of cleanliness in handling and improper storage practices Although it is generally agreed that bakery products are microbiologically safe food but post baking processes, packaging and wrong handling cannot be denied. Bakery products have been an important part of diet. Due to substandard handling operations, mould spoilage has become a serious threat for bakery industries. Further large mass of people like students, children, daily workers, tourists, all prefer bread preparations. Local bread preparations from road side vendors form a major part of their food. Improper handling and storage facilities lead to microbial contaminations as the higher water activity can lead to certain pathogenic anaerobic microbial growth at ambient temperature causing serious unnoticed health hazards. Hence, an attempt was made to collect the local bread samp...
