The solvent extracted vegetable seed oils of Cucurbitaceae family viz. Bitter gourd (Momordica charentia), Small bitter gourd (Momordica dioica), Bottle gourd (Lagenaria siscraria) and Ridge gourd (Luffa acutangula) were evaluated as grain protectant against callosobruchus chinensis on the stored legume-pulse grains. All the vegetable seed oils were found effective as legume-pulse grain protect...

According to the research and observations, pest damage of peanut varieties planted in experimental field institute was different. Peanut oil is used all areas national economy for preparation food, canning, varnish, soap, linoleum, perfumery, printing ink, medicine, vegetable or animal fat. Oilseeds are not limited obtaining oil, their pulp a nutritious feed livestock raw material processing i...

Different non-specific immune parameters and their seasonal changes in spotted Catfish Arius maculates from Vellar estuary was investigated. It was undertaken for a year which included four main seasons of a year such as summer (April-June), Pre Monsoon (July-september), Monsoon (October-December) and Post Monsoon (JanuaryMarch). The Physico-chemical parameters (Temperature, pH, Salinity and Ra...

Nanotechnology has become one of the most promising new approaches for pest control in recent years. In our screening program, laboratory trials were conducted to determine the effectiveness of silica nanoparticles (SNP) and silver nanoparticles (AgNP) on larval stage and adults of Callosobruchus maculatus on cowpea seed. Nanoparticles of silica and silver were synthesized through a solvotherma...

Sexual conflict over reproductive investment can lead to sexually antagonistic coevolution and reproductive isolation. It has been suggested that, unlike most models of allopatric speciation, the evolution of reproductive isolation through sexually antagonistic coevolution will occur faster in large populations as these harbour greater levels of standing genetic variation, receive larger number...

Seeds of various wild and cultivated pulses express varied degrees of resistance to damage by Callosobruchus maculatus, a major pest of stored pulses. Seeds were analysed for trypsin/chymotrypsin inhibitors (qualitatively and quantitatively) and protein pro®les (SDS-polyacrylamide gel electrophoresis) to study the chemical basis of resistance to bruchid infestation. Seeds of the wild pulses Dun...

Development and reproductive success of the solitary egg parasitoid Uscana lariophaga Steffan were examined after development in eggs of the bruchid storage pest Callosobruchus maculatus Fabricius reared at either low or high densities on cowpea seeds and laid at day 1 and 4 of maternal life. Both bruchid larval competition and maternal age negatively affected egg size, but the latter more than...

Over 90% of the insect damage to cowpea seeds is caused by Callosobruchus maculatus. Although, many chemicals have proven their efficacy against C. maculatus, they adversely affect natural environment. Death non-targeted species which are enemies other pests and development resistance possible. Therefore, current study was conducted determine effect plant leaves Murraya koenigii (“Karapincha”),...
