The farmers generally prefer chemical control against to insect pest for their easy application and
high impact in a short time. However, constant and intensive use of chemical pesticides carries
many problems such as residue problem, environmental pollution, deterioration of natural
balance and resistance problems in pest population. İnsect resistance to insecticides become one
of the most important problems caused by the intensive use of chemical pesticides. Because of
these problems, alternative methods and / or products have been searched for pest control,
development of new pesticides was required and the use of microorganism-based biopesticides in
pest control has gained importance. Among the microorganism based biopreparates,
entomopathogenic fungi are characterized by adherence to the insect cuticle, penetration and
reproduction in the hemocoel. There are many registered entomopathogenic fungi based
biopreparates in the world and their usage is increasing day by day. However, there is not yet
much research on whether the problem of resistance to chemical pesticides in pests is valid for
these biopreparates. Therefore, in this study, the mode of action of entomopathogenic fungi and
the potential of pests to develop resistance to these biopreparates have been surveyed.
