The search for new strategies of pest control with safer molecules is currently of great importance and interest. Microbe-mediated biological crop protection is an attractive and promising technology with no concern for a negative impact on the environment and biodiversity. Microbial hydrolytic enzymes such as proteases, chitinases, lipases, etc. are attractive for this purpose. They present toxic properties and act synergistically to control pest attacks. Also, some metabolites, that microorganisms produce for their survival or defense, can be explored and exploited for plant protection. The focus of this Volume is on the potential of microbial hydrolytic enzymes and their metabolites in agroecosystem functioning. Subsequent chapters review topics such as microbial hydrolytic enzymes as powerful management tools, chitinases in IPM of agro-horticultural crops, metabolites as pesticides and the importance of the metabolites of entomopathogenic fungi, metabolites and virulence factors. Other topicas include: microbial-based nanoparticles, recombinant DNA technologies to improve the efficacy of microbial insecticides, the effects of entomopathogens on insect predators and parasitoids, and the management of major vegetable insect pests. This Volume provides detailed accounts on the safe use of microbial products for sustainable management of insect pests. Its aim is to build solid foundations for the students, teachers, and researchers interested in eco-friendly management of important insect crop pests.

This book describes nitric oxide (NO) and hydrogen peroxide (H2O2) functions in higher plants. Much progress has been made in the field of NO and H2O2 research regarding the various mechanisms and functions of these two molecules, particularly regarding stress tolerance and signaling processes, but there are still gaps to be filled. NO and H2O2 are both crucial regulators of development, and act as signaling molecules at each step of the plant lifecycle, while also playing important roles in biotic and abiotic responses to environmental cues. The book summarizes key advances in the field of NO and H2O2 research, focusing on a range of processes including: signaling, metabolism, seed germination, development, sexual reproduction, fruit ripening, and defense.

Comparison is a powerful cognitive research tool in science since it does "across studies" to evaluate similarities and differences, e.g. across taxa or diseases. This book deals with comparative research on plant disease epidemics. Comparisons are done in specifically designed experiments or with posterior analyses. From the apparently unlimited diversity of epidemics of hundreds of diseases, comparative epidemiology may eventually extract a number of basic types. These findings are very important to crop protection. Plant disease epidemiology, being the ecological branch of plant pathology, may also be of value to ecologists, but also epidemiologists in the areas of animal or human diseases may find interesting results, applicable to their areas of research.

Plant diseases, extreme weather caused by climate change, drought and an increase in metals in soil are amongst the major limiting factors of crop production worldwide. They devastate not only food supply but also the economy of a nation. Keeping in view of the global food scarcity, there is, an urgent need to develop crop plants with increased stress tolerance so as to meet the global food demands and to preserve the quality of our planet. In order to do this, it is necessary to understand how plants react and adapt to stress from the genomic and proteomic perspective. Plants adapt to stress conditions by activation of cascades of molecular mechanisms, which result in alterations in gene expression and synthesis of protective proteins/compounds. From the perception of the stimulus to transduction of the signal, followed by an appropriate response, the plants employ a complex network of primary and secondary messenger molecules. Cell signaling is the component of a complex system of communication that directs basic cellular activities and synchronizes cell actions. Cells exercise a large number of noticeably distinct signaling pathways to regulate their activity. In order to contend with different environmental adversities plants have developed a series of mechanisms at the physiological, cellular and molecular level. This two volume set takes an in-depth look at the Stress Signaling in Plants from a uniquely genomic and proteomics perspective. Stress Signaling in Plants offers a comprehensive treatise on the Chapter, covering all of the signaling pathways and mechanisms that have been researched so far. Each chapter provides in-depth explanation of what we currently know of a particular aspect of stress signaling and where we are headed. All authors have currently agreed and abstracts have been complied for the first volume, due out midway through 2012. We aim to have the second volume out at the beginning of 2013. "

This open access book in the field of plant pest detection shows a constant demand in development and improvement of fast and reliable detection tools, especially for high-priority pests. This open access book describes and summarizes the whole process of the organization of test performance study (TPS) for these tools. The outcome of TPS, obtained through the evaluation of the performance of one or more diagnostic tests by several laboratories on defined samples, is the finding of the best performing test/s for particular pest and for specific uses. Nowadays the intensification of worldwide trade and associated controls increases the need for quality assurance accreditation and harmonization of laboratories practices. Therefore, such studies are very important, but, non-existent. Considering those facts, our goal was to develop guidelines, by using the data and experiences of involved partners, for further TPS in the field of plant health. Developed guidelines could be easily transferable to other microbiology fields.

Insects and fungi have a shared history of association in common habitats where together they endure similar environmental conditions, but only recently have mycologists and entomologists recognized and had the techniques to study the intricacies of some of the associations. This new volume covers "seven wonders of the insect-fungus world" for which exciting new results have become available, often due to the use of new methods that include phylogenetic analysis and development of molecular markers.
Eleven chapters of the volume are presented in two sections, "Fungi that act against insects" and "Fungi mutualistic with insects" that cover a number of major themes. Examples of necrotrophic parasites of insects are discussed, not only for biological control potential, but also as organisms with population structure and complex multipartite interactions; a beneficial role for symptomless endophytes in broad-leafed plants is proposed; biotrophic fungal parasites with reduced morphologies are placed among relatives using phylogenetic methods; complex methods of fungal spore dispersal include interactions with one or more arthropods; the farming behavior of New World attine ants is compared with that of humans and the Old World fungus-growing termites; certain mycophagous insects use fungi as a sole nutritional resource; and other insects obtain nutritional supplements from yeasts.
Insects involved in fungal associations include--but are not limited to--members of the Coleoptera, Diptera, Homoptera, Hymenoptera, and Isoptera. The fungi involved in interactions with insects may be clustered taxonomically, as is the case for Ascomycetes in the Hypocreales (e.g., Beauveria, Metarhizium, Fusarium), ambrosia fungi in the genera ophiostoma and ceratocystis and their asexual relatives, Laboulbeniomycetes, Saccharomycetes, and the more basal Microsporidia. Other groups, however, have only occasional members (e.g., mushrooms cultivated by attine ants and termites) in such associations. The chapters included in this volume constitute a modern crash course in the study of insect-fungus associations.
