Insect defence: its impact on microbial control of insect pests
Insects are the earliest and most diverse taxon of animals accounting for more species than all other animals put together because of their high reproductive potential and varied niche. Though cellular reactions like phagocytosis, nodulation and encapsulation and humoral reaction through secretion of antibacterial proteins are known for fungus and bacterial invaders, little is known about insec...
متن کاملInsect pathology and fungal endophytes.
Fungi that occur inside asymptomatic plant tissues are known as fungal endophytes. Different genera of fungal entomopathogens have been reported as naturally occurring fungal endophytes, and it has been shown that it is possible to inoculate plants with fungal entomopathogens, making them endophytic. Their mode of action against insects appears to be due to antibiosis or feeding deterrence. Res...
متن کاملUnusual microbial xylanases from insect guts.
Recombinant DNA technologies enable the direct isolation and expression of novel genes from biotopes containing complex consortia of uncultured microorganisms. In this study, genomic libraries were constructed from microbial DNA isolated from insect intestinal tracts from the orders Isoptera (termites) and Lepidoptera (moths). Using a targeted functional assay, these environmental DNA libraries...
متن کاملInsect Growth Regulators for Insect Pest Control*
Insecticides with growth regulating properties (IGR) may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Some insects exposed to such compounds may die due to abnormal regulation of hormone-mediated cell or organ development. Other insects may die either from a prolonged exposure at the developmental st...
متن کاملMicrobial Weed Control and Microbial Herbicides
Microbial weed control represents an innovative means to manage troublesome weeds and utilize the naturally occurring biological herbicides produced by soil microorganisms. These compounds kill or hinder the growth of weeds so that beneficial plant species can gain a competitive advantage. The vast diversity of microorganisms in our environment is largely untapped, and the potential discovery a...
