For the pest management of insect pests the biological control methods are suggested to reduce the toxicity danger of insecticides to
man, animals and environment.  
  The biological pest control has a lot of advantages most important of which are the safety of its application to man and
environment, the permanent results and the maintenance of balance in the
ecosystem.

  In many applications of biological pest control for insect pests in urban and suburban green
places, as well as in extensive agricultural practice, there have been occasionally mass applications of beneficial and other organisms
(such as entomopathogenic fungi) with much effectiveness.  
  These beneficial organisms can be produced after reproduction in the
insectary, or been supplied from the trade.

  The usual entomological pests that we see today in green
places, where the application of biological pest control is possible, are mainly insect pests from aphids
(Hemiptera: Aphidoidea), scale insects (Hemiptera: Coccoidea), whiteflies (Hemiptera:
Aleyrodidae), larvae (Lepidoptera) etc.  
  Examples of such applications that have been applied successfully are the
