THE PEAR BLISTER-MITE. 

 (Eriophyes pyri (Pgst) Nal.) 



By P. J. Farrott. Gem va, Y. Y. 



This mite was undoubtedly introduced at an early period into the 

 United State- in foreign importation- of nursery stock and was 

 probably well distributed in many fruit-growing areas long before 

 it- presence was recognized. The first writer to direct attention to 

 it- appearance as an orchard pe>t in this country was Mr. Townend 

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

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

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

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

 said to be inhabited by myriad- of -mall mite-. The species was 

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

 as " Typhlodromw 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. V.. August, 1879, Dr. W. S. 

 Barnard' presented a paper on "bud-blight insects," in which he 

 attributed the brown and black blotches of pear leave- to the activ- 

 ities of mite-. In 1880, Prof. T. J. Burrill '■ called attention to a 

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

 large, which was ascribed to the work of the mite Phytoptus pyri 

 Scheuten. lie 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 year- the work of tin- species 

 was recognized in many State- and was given widespread mention. 

 In 1883 • the mite was observed in large numbers upon imported 

 Russian pear trees in experimental nurseries in Iowa, and by L894
