The insect 1 remain in symbiotic associations with a tremendous
number of microorganisms, and some of them could be classified as
parasitic/pathogenic. Without question, insect pathogens act as
natural mortality agents and represent the third leg of the triad
of biological control which is an environmentally sound alternative
to chemical control. The virulence and pathogenicity of an insect
parasite i. e. disease agent are determined by the microbial genome
as a result of the coordinated expression of a concert of genes.
These genes may be organized as cassettes and be associated with
transmissible DNA. The acquisition of these domains or
pathogenicity islands, may be sufficient to develop a transgenic
virulent pathogen. The insect pathogens are very specific and this
property can be exploited in making insects sick. However, rarely
have field applications of highly virulent strains of viruses,
fungi, bacteria, protozoa resulted in massive insect population
reductions or induced widespread, persistent epizootics as the same
is also governed by host susceptibility regulated by genetics, age,
sex and physiological state of the host. Insect pathogens causing
acute or chronic diseases must be able to persist in the
environment, to multiply in the host, and to spread to other
susceptible hosts. In this book, I have attempted to bring together
all recent studies regarding both fundamental and more applied
research aspects related to entomopathogens, bacteria, viruses,
fungi and nematodes in order to facilitate their development and
commercial exploitation.
