THE PEAR BIISTEE-MITE. 



{Eriophijcx piiri (Pjist. ) Nal.) 

 By P. J. Pakkott. Got era, X. Y. 



This mite was undoubtedly introduced at an early period into the 

 United States in foreign importations of nursery stock and w^:s 

 probably well distributed in many fruit-growing areas long before 

 its presence was recognized. The first writer to direct attention to 

 its appearance as an orchard pest in this country was Mr. Townend 

 Glover," Entomologist of U. S. Department of Agriculture, who 

 in May, 1872, received specimens of its work from a correspondent. 

 Under his direction Mr. Thomas Taylor, microscopist, examined some 

 of the pear leaves covered with dark-brown blotches, which were 

 said to be inhabited by myriads of small mites. The species was 

 thought to be somewhat similar to the mite mentioned by Packard '' 

 as •' 7'{/phIodrom>'s pyri of Scheuten," known to infest pear trees 

 in Europe. 



Before the meeting of the American Association for the Advance- 

 ment of Science, held at Saratoga, X. Y., August, 1870, Dr. W. S. 

 Barnard " presented a paper on " bud-l)light insects," in which he 

 attributed the brown and black l)lotches of pear leaves to the activ- 

 ities of mites. In 18S0, Prof. T. J. Burrill " called attenticm to a 

 widespread disease of jjear leaves in Illinois and in the country at 

 large, Avhich was ascribed to the work of the mite J^liyfoptus pyri 

 Scheuten. He mentioned the fact of the hibernation of the mites 

 under the bud scales and the probable dissemination of these crea- 

 tures in cions and buds. In succeeding years the work of this species 

 was recognized in many States and Avas given widespread mention. 

 In 188?) <■ the mite was observed in large numbers upon im])orted 

 Russian pear trees in experimental nurseries in Iowa, and by 1894
