Abstract

The present investigations were undertaken on laboratory studies of Trichogramma chilonis (Ishii) and Trichogramma japonicum (Ashmead) during the year 2013-2014 in the bio-control laboratory, Department of Agricultural Entomology, College of Agriculture, Dapoli (Maharashtra). Effect of low temperature storage at 15°C temperature for varying period on egg cards parasitised by T. chilonis and T. japonicum, 4 day after parasitisation revealed that parasitised trichocards after 4 days of parasitisation can effectively stored up to 15 days without much effect on adult emergence.

Keywords

Adult Emergence, Parasitisation, Trichogramma chilonis, Trichogramma japonicum.

Abstract

Automobile sector is very fast growing in recent times, as many want more sophistication and comfort. The automotive industry in India is one of the largest automotive markets in the world. It was previously one of the fastest growing markets globally, but it is currently experiencing flat or negative growth rates. In 2009, India emerged as Asia's fourth largest exporter of passenger cars, behind Japan, South Korea, and Thailand, overtaking Thailand to become third in 2010. As of 2010, India was home to 40 million passenger vehicles. More than 3.7 million automotive vehicles were produced in India in 2010 (an increase of 33.9%), making India the second fastest growing automobile market in the world (after China). India's passenger car and commercial vehicle manufacturing industry recently overtook Brazil to become the sixth largest in the world, with an annual production of more than 3.9 million units in 2011. From 2011 to 2012, the industry grew 16-18%, selling around three million units. Annual vehicle sales are projected to increase to 4 million by 2015, not 5 million as previously projected [Source: Society of Indian Automobile Manufacturers (SIAM)].

Abstract

The present investigations were undertaken on laboratory studies of Trichogramma chilonis (Ishii) during the year 2013-2014 in the Bio-control laboratory, Department of Agricultural Entomology, College of Agriculture, Dapoli (Maharashtra).The results of effect of different insecticides on adult emergence of T. chilonis revealed that insecticides viz., oxydemeton methyl can be safely used in the field after release of T. chilonis. However, insecticides viz., cypermethrin, dimethoate, indoxacarb and emamectin benzoate can be wisely used in the field 4-5 days after release of T. chilonis, while malathion and dichlorvos should strictly be retrained from their use as they reduce the per cent adult emergence.

Abstract

Magnesium (Mg) and its alloys are gaining wide popularity as promising candidates for automobile, aerospace and structural applications. On the other hand, friction stir processing (FSP) is a solid state technique used to alter the microstructural characteristics of a metal. In the present study, AZ91 Mg alloy was processed by FSP at optimized process parameters. The microstructural changes were analyzed and found that the presence of secondary phase (Mg₁₇Al₁₂) was reduced. The network like structure of secondary phase that was appeared at the grain boundary before FSP has disappeared after the processing. Grain size was also found to be reduced from (66.5 ° 8.7 μm) to (4.1° 1.6 μm). The corrosion behavior was assessed by immersion test in 3.5%NaCl solution and found that the processed AZ91 has lower corrosion rated during the early hours of corrosion attack. However, after 72 h of immersion the corrosion resistance of the processed AZ91 was found to be reduced. Hence from the present study it can be understood that the presence of secondary phase has a great influence on the corrosion behavior of AZ91 mg alloy and that can be altered by grain refinement.

Keywords

FSP, AZ91 Mg Alloy, Secondary Phase, Corrosion, Grain Refinement.
