mates that there was only about 10 per cent of an apple crop in Idaho 
in 1901, and his estimate is probably not far from correct. 
On account of this short crop the price of apples was high and those 
who could save a large part of what crop they had made good profits. 
INJURY DUE TO CODLING MOTH IN 1901. 
On account of the small crop it is impossible to give an estimate that 
is of any value in regard to the damage by the insect in 1901. It was 
certainly much greater than in 1900. 
In orchards with but little fruit the apples were all wormy, many 
of them containing from 5 to 10 holes. The writer counted the 
remains of 23 eggs on one apple and 17 on another. 
The number of the insects was decreased but little by the freeze, 
while the number of fruits they had to work upon was greatly les- 
sened. Consequently, in the orchards that were well cared for a large 
percentage of the fruits was wormy in spite of spraying and banding. 
The following are estimates of injury by the codling moth in individ- 
ual orchards and in localities: 
M. A. Kurtz, at Nampa, had over half a crop of apples. Many of them were under- 
sized. Spraying and banding were well done. The loss for the whole orchard was 
about 20 per cent. 
Mr. C. Hinze, Payette, had about halfa crop of Jonathans. About 50 per cent 
was saved from this insect. Spraying alone was used. 
Hon. Edgar Wilson had a small crop of Ben Davis and Jonathans. Early spray- 
ings were made and bands were used. Less than 40 per cent of these were saved. 
Mr. John McGlinchey had nearly a full crop at Payette. Early sprays were made 
but banding was neglected. Not over 20 per cent was saved. 
Mr. Seth Heath, 9 miles from Mountainhome, thinks he saved 80 per cent of his 
apples and pears. Spraying and banding and other measures were used. 
Mr. W. 8S. Whitehead, of Boise, saved only about 20 per cent by spraying and no 
banding. 
Many orchards were noted in various localities where all the fruit was wormy. 
Professor-Aldrich has found that the damage in and about Moscow was about 5 
per cent. 
It was reported that about Walla Walla, Wash., and in the valley of the upper 
Columbia River the conditions were about as they were in the Boise Valley. 
In the Willamette Valley the writer has been told that the injuries where no meas- 
ures were used yaried from 30 to 80 per cent. 
In southern Oregon the writer found orchards near Central Point in which the 
injury did not exceed 5 per cent. Inan untreated orchard 20 per cent of the apples 
were estimated to be damaged. Growers said that this orchard showed much less 
injury than many others in that locality. 
FRUITS INFESTED BY THE CODLING MOTH. 
The apple is by far the most subject to the attacks of this pest, and 
practically all of the work has been directed against the insect in this 
fruit. 
In 1900 it was noted that some varieties of apples were more subject
