Gillette! suggested the use of strong soap suds, kerosene emulsion 
or sulphur during the dormant season as means of control likely to 
give efficient results. Profs. Bailey and Dudley” in 1890 recorded 
an abundant infestation by this pest in the pear orchards of New 
York. In the same year, Profs. Comstock and Slingerland*® pub- 
lished the details of some interesting tests with kerosene emulsion 
to determine if applications to affected leaves would control inites. 
In this work only negative results were obtained. In the following 
year the presence of the pest was noted in Canada*, Delaware’, 
and Pennsylvania®. At the annual meeting of the Association of 
Economic Entomologists in 1892, Prof. Slingerland’ reported that 
thorough spraying of dormant buds had proven an efficient remedy 
for the protection of pear trees. At this same meeting the pest was 
recorded in excessive abundance in the pear orchards of Eastern 
New York, Ohio, and New Jersey. In 1894 the mite was regarded 
as being generally distributed in the pear growing belts of Iraho,® 
California? and Oregon. 
THE MITE AS AN APPLE PEST. 
The mite has long been known to infest apple trees on the Con- 
tinent but its work in this capacity in the United States is only of 
recent recognition. The pest has quite likely been present upon 
apple trees in New York for many years but important injuries by 
it were not brought to the Station’s attention till 1902, when it was 
found to be very abundant in W. P. Rogers’ orchard at William- 
son. In 1903 the infestation of these trees was more conspicuous 
and attracted considerable attention from the fruit-growers in 
attendance at the summer meeting of the State Fruit-Growers’
