Thus, recommendations and conclusions would be built on scientist and researcher visions added regarding to their research findings. In addition, this chapter includes information on a set of conclusions and recommendations to direct future research toward industry of biological control, which is one of the main tactical strategies of the Egyptian economy and environment.
