This pest is being reported from several 
W« P. Flint (May 16): An unusually high percentage of scale have 
survived the winter in southern Illinois. Examinations of unsprayed 
apple and peach trees made from May 1 to the 5th, shows from 10 to 
76 per cent of the scale alive. Results of spraying with the lubricat- 
ing oil emulsion have been excellent. This material has been generally 
used by orchardists in the southern and western fruit districts. 
Leonard Has em an (May 22): Good results on control have been secured 
with iubricating-oil emulsion. Experiments with different strengths 
make:: it f-se em: likely that this emulsion has a great future. Male 
scales in central Missouri began emerging between May 10 and May 15. 
OYSTER-SHELL SCALE (Lepidosaphes ulrni L.) 
New York C. R. Crosby and assistants: This insect has been reported as being 
quite generally abundant over the fruit growing sections o'-f the State, 
becoming very abundant in many apple orchards. 
Indiana H. F. Dietz (May 19): Hatching of eggs of the light-brown form of 
this insect began on May 15, which is 18 days later than last year. 
This is a two-brooded form. No hatching of the gray-brown form, 
which is single- ore oded, has been observed about Indianapolis. 
Nebraska M. H. Swenk (May 15): Several reports of injury by the oyster-shell 
scale have oeen received during the period covered by this report. 
EUROPE/ M RED SPIDER (P aratetranychus nilosus C. & F.) 
Massachusetts A. I. Bourne (May 22): European red mites were found about the first 
week in May at Amherst and are now quite prevalent throughout all of 
the blocks of apples, particularly on Baldwins, although they a.re not 
as abundant as has been the case during the last two or three seasons 
One report has been received from outside the Connecticut Valley. 
This is from Harvard in Worcester County, where they are reported as 
quite numerous and quite generally spread throughout the orchard, 
where they were found on tender opening leaves. 
New York C. R. Crosby and assistants: This insect has been reported as more 
or less numerous in Rockland, Orange, Orleans, Ulster and Dutchess 
Counties . 
Ohio H. A. Gossard (May ll) : Eggs of the European red spider were re- 
ceived on May 1C from a suburb of Cleveland. 
PEAR 
PEAR PSYLLA ( Psvlla pyricola Eoerst.) 
Massachusetts A. I. Bourne (May 22): During the first -week in May pears at Amherst 
•were found to be infested and egg laying was under way. Eggs were 
so numerous that in many cases on a single fruit spur 50 to 60 eggs 
could be counted. This is the most serious infestation that we have 
had for several years. Very few inquiries have been received from 
other parts of the State, so the outbreak is probably local.
