REPORT OF STATE ENTOMOLOGIST. 21/ 



to follow such a method of procedure. Instead of being theo- 

 rists we must become systematists by using our appHed science 

 and eHminate all of the errors of theory and practice and place 

 our profession, as does the merchant or manufacturer, on a 

 standard scientific system. 



One of the most important factors in the successful prosecu- 

 tion of the orchard industry is the proper control of our insect 

 enemies. There are hundreds of these insects that prey upon the 

 apple tree, either in the root, trunk, bark, twig, leaf, blossom or 

 fruit. Some of the more important ones are the round head 

 horer,Saperda Candida; the flat headed borer, Chryobothris fe- 

 moral a; the bud moth, Tuietoccra occUana; oyster-shell bark- 

 louse, Lepidosaplies ulnii; Red-humped apple worm, Schisura 

 concinna ; Apple maggot. Carpocapsa pomonella ; Railroad worm, 

 Rhagoletis pomonella. 



We also have the fungus diseases, the apple scab and dry rot 

 to contend with. The most of these can be easily controlled by 

 spraying at the proper time. The others can be handled after 

 learning their habits, by a study of their life histories. 



Farming Special. 



A "Farming Special" was run over the Bangor and Aroos- 

 took Railroad in April and another over the Maine Central in 

 June. They were under the supervision of President Fellows 

 of the University of Maine. One of the features of the exhibit 

 was a collection of specimens illustrating the difterent orders of 

 insect life. It represented many of our common injurious forms 

 as well as some beneficial ones. Among others the life histories 

 of the gipsy and brown-tail moths were given. 



This collection attracted a great deal of attention and was the 

 means of disseminating much valuable information and arousing 

 an interest in our insect pests that will ultimately lead to greater 

 success in the control of them by our farmers and orchardists. 



Exhibitions at Fairs. 

 Several requests were made for a collection of injurious in- 

 sects to be placed on exhibition at the State Fairs. Two dozen 

 Riker mounts were prepared showing the life histories of many 

 ^of our most injurious insects including the brown-tail and gipsy
