50 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 15 



It must be made clear to every student in economic entomology that 

 our studies in the sciences have been too restricted and that there is 

 such an interrelation and interdependence of our problems with those 

 of other fields that the development and solution of them cannot be 

 considered separately without loss. 



The entomologist of the future will be required more than ever . 

 before to deal with problems involving interrelationships between many 

 fields of science. Unless he has a comprehensive knowledge of chemistry, 

 physics, plant pathology, plant genetics, agronomy, horticulture, 

 geology, bacteriology, sanitation, and other subjects likely to enter into 

 his problem, he cannot expect to get basic results which will contribute 

 to the development of a nation. It is not meant that the entomologist 

 must be a specialist in all the biological sciences. This is impossible. 

 But it is meant that if an entomologist is to develop successfully a problem 

 and overcome its difficulties, he must be equipped with sufficient funda- 

 mental training in the different lines to be able to recognize the ob- 

 stacles encountered, and interpret the factors involved in his experi- 

 ment. And when he has done this, he should be big, broad and generous 

 enough to invite to his assistance the scientists who can materially 

 contribute to the solution of his problem. In fact, his training should 

 be such that, in planning and developing his problem he will be able to 

 foresee the different interrelationships and the possible and probable 

 difficulties, and sense the desirability of calling into consultation, and 

 even active participation, investigators in other lines. The effective 

 method of Hessian fly control in Kansas is not the product of an ento- 

 mologist, but the product of a long series of cooperative experiments of 

 entomologists and agronomists. 



Kanred wheat, a hard winter variety that is outyielding any other 

 hard wheat by several bushels per acre, that is rust-resistant, that 

 stands at the top in milling and baking qualities, is not the product of a 

 single individual, but is the product of the Kansas Agricultural Ex- 

 periment Station. It was bred and selected by a plant geneticist. 

 Its yielding qualities were determined by agronomists in cooperative 

 work with farmers; its rust-resistant characters were asceitained by a 

 plant pathologist, and its milHng and baking qualities were the work of 

 flour milling engineers, baking experts and flour chemists. 



If any Experiment Station produces a wheat that is Hessian fly 

 resistant and has the other necessary- important characters, it will not 

 be the work of an entomologist alone, but will be the result of a coopera- 

 tive project between entomologists, plant geneticists, plant physi- 

 ologists, plant pathologists, and agronomists.
