Entomopathogenic fungi vary considerably in their mode of action and
virulence. Successful infection depends primarily on the adherence and
penetration ability of a fungus to the host integuments. A variety of
extracellular enzymes is produced during the degradation of insect
integument. The attempts to control insects have changed over time from
chemicals to natural control methods. This is why the development of natural
methods of insect control or biopesticides, is preferred. By the use of
fungal entomopathogens, insect pests can be controlled. There is no doubt
that insects have been used for many years, but their effective use in the
field remains elusive. However, their additional role in nature has also been
discovered. Comparison of entomopathogens with conventional chemical
pesticides depends on their efficiency and cost. In addition to efficiency,
there are advantages in using microbial control agents, such as human safety
and other non-target organisms; pesticide residues are minimized in food and
biodiversity increased in managed ecosystems. In the present review the
pathogenicity and virulence of entomopathogenic fungi and their role as
biological control agents using biotechnology will be discussed.
