Rapid molecular identification and typing of micro-organisms is extremely important in efforts to monitor the geographical spread of virulent, epidemic or antibiotic-resistant pathogens. It has become a mainstay of integrated hospital infection control service. In addition, numerous industrial and biotechnological applications require the study of the diversity of organisms. Conventional phenotypic identification and typing methods have long been the mainstay of microbial population and epidemiological studies, but such methods often lack adequate discrimination and their use is normally confined to the group of organisms for which they were originally devised. Molecular fingerprinting methods have flourished in recent years and many of these new methods can be applied to numerous different organisms for a variety of purposes. Standardisation of these methods is vitally important. In addition, the generation of large numbers of complex fingerprint profiles requires that a computer-assisted strategy is used for the formation and analysis of databases. The purpose of this book is to describe the best fingerprinting methods that are currently available and the computer-assisted strategies that can be used for analysis and exchange of data between laboratories. This book is dedicated to the memory of Jan Ursing (1926 - 2000), Swedish microbiologist, taxonomist and philosopher. "...taxonomy is on the borders of philosophy because we do not know the natural continuities and discontinuities..."

Bio-control is a major tactic in the integrated pest management system. Entomopathogenic nematodes have been recognized as one of the potential and most effective biocontrol agent for the control of major insect pest which cause serious damage to food and fiber crops of agricultural importance for the control of insect pest in agricultural crops like cotton and fruit trees, a wide range of chemical pesticides have been indiscriminately used since many decades. The long lasting impact of the chemical on the non target organism, development of insect resistance to chemical pesticides and its hazardous effects on the human and the environment, stimulated the interest of the scientist for an alternate control measure through the biocontrol means for destroying the insect pests as to increase the agricultural productivity. Among the insect pathogens entomopathogenic nematodes have been considered as exceptionally effective biocontrol agents having non polluting properties.

The definition "biological control" has been used in different fields of biology, most notably entomology and plant pathology. It has been used to describe the use of live predatory insects, entomopathogenic nematodes (EPNs) or microbial pathogens to repress populations of various pest insects in entomology. EPNs are among one of the best biocontrol agents to control numerous economically important insect pests, successfully. Many surveys have been conducted all over the world to get EPNs that may have potential in management of economically important insect pests. The term "entomopathogenic" comes from the Greek word entomon means insect and pathogenic means causing disease and first occurred in the nematology terminology in reference to the bacterial symbionts of Steinernema and Heterorhabditis. EPNs differ from other parasitic or necromenic nematodes as their hosts are killed within a relatively short period of time due to their mutualistic association with bacteria. They have many advantages over chemical pesticides are in operator and end-user safety, absence of withholding periods, minimising the treated area by monitoring insect populations, minimal damage to natural enemies and lack of environmental pollution. Improvements in mass-production and formulation technology of EPNs, the discovery of numerous efficient isolates and the desirability of increasing pesticide usage have resulted in a surge of scientific and commercial interest in these biological control agents.

This book describes entomopathogenic and slug parasitic nematodes as potential biocontrol agents in crop insect and slug pest management. Addressing research on these two nematodes from tropical, subtropical and temperate countries, it covers the new techniques and major developments regarding mass production, formulation, application, commercialization and safety measures. Plans for future strategies to make these beneficial nematodes cost-effective and expand their use by including them in integrated pest management programmes in different agro-ecosystems are also discussed. Biocontrol Agents: Entomopathogenic and Slug Parasitic Nematodes provides a comprehensive review of the topic and is an essential resource for researchers, industry practitioners and advanced students in the fields of biological control and integrated pest management.

Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.
