“…A set of different molecules from Streptomyces spp. that act against insect pests have been found and characterized; these are, for instance, flavensomycin [ 194 ], antimycin A [ 195 ], piericidins [ 196 ], macrotetralides [ 197 ] and prasinons [ 198 ]. Streptomyces avermitilis , a common soil inhabitant, was shown to produce avermectins, molecules with potent activity against arthropods and nematodes [ 199 ].…”

There has been many recent studies on the use of microbial antagonists to control diseases incited by soilborne and airborne plant pathogenic bacteria and fungi, in an attempt to replace existing methods of chemical control and avoid extensive use of fungicides, which often lead to resistance in plant pathogens. In agriculture, plant growth-promoting and biocontrol microorganisms have emerged as safe alternatives to chemical pesticides. Streptomyces spp. and their metabolites may have great potential as excellent agents for controlling various fungal and bacterial phytopathogens. Streptomycetes belong to the rhizosoil microbial communities and are efficient colonizers of plant tissues, from roots to the aerial parts. They are active producers of antibiotics and volatile organic compounds, both in soil and in planta, and this feature is helpful for identifying active antagonists of plant pathogens and can be used in several cropping systems as biocontrol agents. Additionally, their ability to promote plant growth has been demonstrated in a number of crops, thus inspiring the wide application of streptomycetes as biofertilizers to increase plant productivity. The present review highlights Streptomyces spp.-mediated functional traits, such as enhancement of plant growth and biocontrol of phytopathogens.

“…Other species and strains in this genus produce a variety of metabolites acting as potent toxins against either phytopathogenic microbials or insect pests [ 60 ]. Among the first discovered insecticidal substances produced by Streptomyces species are flavensomycin [ 61 ], antimycin A [ 62 ], piericidins [ 63 ], macrotetralides [ 64 ] and prasinons [ 65 ]. Later on, the insecticidal and anthelmintic activities of avermectins produced by the soil Actinomycete Streptomyces avermitilis MS & Dwas, were discovered [ 66 ].…”

The scientific community working in the field of insect pathology is experiencing an increasing academic and industrial interest in the discovery and development of new bioinsecticides as environmentally friendly pest control tools to be integrated, in combination or rotation, with chemicals in pest management programs. In this scientific context, market data report a significant growth of the biopesticide segment. Acquisition of new technologies by multinational Ag-tech companies is the center of the present industrial environment. This trend is in line with the requirements of new regulations on Integrated Pest Management. After a few decades of research on microbial pest management dominated by Bacillus thuringiensis (Bt), novel bacterial species with innovative modes of action are being discovered and developed into new products. Significant cases include the entomopathogenic nematode symbionts Photorhabdus spp. and Xenorhabdus spp., Serratia species, Yersinia entomophaga, Pseudomonas entomophila, and the recently discovered Betaproteobacteria species Burkholderia spp. and Chromobacterium spp. Lastly, Actinobacteria species like Streptomyces spp. and Saccharopolyspora spp. have gained high commercial interest for the production of a variety of metabolites acting as potent insecticides. With the aim to give a timely picture of the cutting-edge advancements in this renewed research field, different representative cases are reported and discussed.

AII rights, especially that of tnmslation into foreign languages, reserved. It is also forbidden to reproduce this book, either whole DedicationFor most areas of scientific pursuit, there is usually that rare investigator who has the imagination to conceive ideas, who has faith in his visions, and who has the ability to critically test his concepts in the laboratory. Almost invariably, this scientist also inspires younger men to enthusiastically enter into his research program. To him should go the accolades and the recognitions of the esteem in which he is held. As only a small part of this esteem, we wish to dedicate these books to Professor SELMAN A. W AKSMAN in appreciation of his leadership and contributions in all facets of antibiotic research. PrefaceThe idea for publishing these books on the mechanism of action and on the biosynthesis of antibiotics was born of frustration in our attempts to keep abreast of the literature. Gone were the years when we were able to keep a bibliography on antibiotics and feel confident that we could find everything that was being published on this subject. These fields of investigation were moving forward so rapidly and were encompassing so wide a range of specialized areas in microbiology and chemistry that it was almost impossible to keep abreast of developments. In our naivete and enthusiasm, however, we were unaware that we were toying with an idea that might enmesh us, that we were creating an entity with a life of its own, that we were letting loose a Golom who instead of being our servant would be our master.That we set up ideals for these books is obvious; they would be current guides to developments and information in the areas of mechanism of action and biosynthesis of antibiotics. For almost every subject, we wished to enlist the aid of an investigator who himself had played a part in determining the nature of the phenomena that were being discussed. One concept for the books was that they include only antibiotics for which a definitive, well-documented mechanism of action or biosynthetic pathway was known. Yet, such an approach would not entirely serve the purpose we projected, for it would not encompass all of the information available in these fields of antibiotic investigations and blind searches for the original literature would still have to be made. We therefore chose to include any and all antibiotics about which some pertinent information had been published. It was obvious even at the start that such a compilation, integration, and analysis of information could never be complete unless scientific investigations ceased at the moment the last manuscript was submitted-an end that was neither desirable nor possible. An addendum was therefore included at the end of the volume and left open for the addition of new information until the last pages of the regular articles had been printed.The original concept has also been further expanded as the authors of several papers found it advisable to elaborate on their subject. Some of the articles included discussions...
