AIM, CONTENT, AND POINT OF VIEW 21 



In this paper Forbes defines (pp. 16-18) ecology and 

 points out, I believe for the first time, that economic 

 entomology is simply applied ecology. He says, 

 "The study of oecology is thus to the economic en- 

 tomologist what the study of physiology is to the 

 physician."
