Applied or practical entomology is so obviously that phase of ento- 

 mology which is useful or of immediate value that further definition 

 appears unnecessary. Numerous efforts being made to conserve and 

 increase the food supply and natural resources of the nation lead us to 

 question seriously whether our entomology is sufficientlj^ practical to 

 measure up to the present needs of the day. There have been during 

 the last few months various efforts to bring the practical applications 

 of entomology more closely home to the fruit grower and the farmer. 

 The letter, the circular, and the printed sheet have been used freely, 

 and yet it is probable that some of the most effective work has been 

 accomplished through county or other local agents with more or less 

 of an official standing. The county agent has served as both the eye 

 and the interpreter for the entomologist, reporting upon develop- 

 ments in the field, and personalh' explaining and supervising preventive 

 and control measures. The right man in the field can undoubtedly 

 accomplish much in bringing about a better handling of the insect 

 problem, since most farmers are much more favorably inclined toward 

 a tactful discussion and demonstration than a more or less lengthy 

 letter or bulletin giving directions for procedure. 



The value of this work must depend in large measure upon the 

 possibility of anticipating insect injury. The first year under such a 

 system cannot begin to be as successful as later ones l^ecause it is very 

 difficult, in fact almost impossible, to anticipate local developments 

 without some previous experience. Moreover, the significant features,
