The BEVS continues to evolve as a powerful, flexible tool for molecular biology, protein function, and biomedical research. Future developments offer the promise of replacement of hazardous chemical insecticides with environmentally safe biopesticides, construction of baculovirus vectors which encode genes for specific post-translational modifications, and establishment of efficient, stably tra...

Normal insect development requires a precisely timed, precipitous drop in hemolymph juvenile hormone (JH) titer. This drop occurs through a coordinated halt in JH biosynthesis and increase in JH metabolism. In many species, JH esterase (JHE) is critical for metabolism of the resonance-stabilized methyl ester of JH. JHE metabolizes JH with a high kcat/KM ratio that results primarily from an exce...

In today's world, food security is an important issue. Food shortages push prices up, impacting upon the health and well-being of hundreds of millions of rural poor across the globe. One way to increase food security is to decrease the amount of yield lost to pests. This encyclopedia provides a comprehensive overview of the fight against pests, covering chemical pesticides, biocontrol agents an...

Plants are attacked by various phytopathogenic fungi. For many years, synthetic fungicides have been used to control plant diseases. Although synthetic fungicides are highly effective, their repeated use has led to problems such as environmental pollution, development of resistance, and residual toxicity. This has prompted intensive research on the development of biopesticides, including botani...

Use of synthetic pesticides causes some unfortunate consequences such as environmental pollution, pests/ vector resistance and toxicity to other non-target organisms including human beings, biological pesticides from plant, microbial origin are environmentally safe pesticides. Microbial insecticides are especially valuable because their non-toxicity to non-target animals and human beings. Labor...

Soil amendments are a broad class of materials that enhance physical, chemical or biological characteristics in croplands, pastures, rangelands. While organic soil such as manure, mulch and seaweed have well established agronomic benefits, there has been renewed private governmental interest quantifying incentivizing their role mitigating climate change. Likewise, biostimulants biopesticides, w...

Microbes are good sources of biologically active compounds that can be used as pharmaceuticals and agrochemicals. As part of our continuous efforts in search for biopesticides from natural sources, a fungus is isolated from leaves of Pandanus amaryllifolius that shows severe necrosis. This fungus is cultured in potato dextrose agar and identified as Curvularia intermedia. The ethyl acetate extr...
