uGO Report op the Entomologists op the 



From this time up to the present day, this troublesome insect 

 has been repeatedly discussed in the reports of the yarious state 

 and government entomologists, as well as in the agricultural 

 press. Prominent among the earlier writers on this subject may 

 be mentioned Dr. C. V. Riley, who published a comparatively 

 long article on the Peach-tree Borer in 1868, in his First Missouri 

 Report, as well as many of a similar nature at later dates; also 

 Dr. Thomas and Dr. Forbes, in whose reports as State Entomolo- 

 gist for Illinois this insect is frequently mentioned. In 1870 

 Prof. Comstock referred at some length to this insect in his report 

 as Entomologist of the United States Department of Agriculture. 

 The reports of the State Entomologist of New York, by Dr. Lint- 

 uer, and those of the Entomologist of the Dominion of Canada, 

 Dr. James Fletcher, furnish a number of references to this insect, 

 and accounts of its life-history and destructive habits. All of 

 these writers speak of the serious injury to fruit trees caused by 

 the borer, and in most, if not all, cases mention the need of great 

 care by fruit-growers to prevent the increase of this pest. 



Distribution. 



As previously stated, this insect is well known in every section 

 of the United States where peaches are grown to any extent. In 

 Circular No. 17, United States Department of Agriculture, 

 Division of Entomology, Mr. Marlatt stated that the records of 

 the division show that this insect is found from " Maine south- 

 ward to the Gulf and westward to the Pacific slope." 



Means of distribution. — The distribution within an orchard or 

 from one orchard to another is easily effected by means of the 

 female, as she can fly for some distance with comparative ease, 

 even when heavy with eggs. But the carrying of the insect from 

 one state to another or from one section of a state to another is 

 undoubtedly most frequently effected by means of nursery stock. 

 It is a too common occurrence in our own state to find many 

 young peach trees in the packing shed, waiting to be shipped, 

 which are infested with borers. Within the past few months 

 luindn-ds of such trees have been found which were about to be
