LEAFHOPPSRS ( Erythroneura spp. ) 
Missouri. L. Haseman (March 24): The two comnon st)ecies of a^-ole leaf- 
hoT>pers, the red-spotted (E. maculata Gill.) and the red-striped 
(E. obligua Say) have survived the severe winter, though recent counts 
indicate between 40 and 50 percent mortality in leaf and grass cover- 
age in the orchards at Columbia. These leafhorroers for the oast two 
seasons have been very serious and we are hoping that the winter 
mortality may somewhat lighten uo their numbers for the coming summer. 
SAN JOSE SCALE ( Astddiotus -oerniciosus Coras t".) 
New Yorlr. P. J. Parrott (March 19): San Jose scale is common in many 
poorly sprayed and neglected orchards in western New Yorlc. 
Virginia. 17. J. Schoene (March 25): Examinations at various points in 
the State indicate that more San Jose scale is present than for several 
years. 
Georgia. 0. I. Snapp (March 3): Thirty- three thousand scales from 
unsorayed peach trees at Fort Valley were counted at intervals during 
the winter to determine the percentage of live scale in an orchard 
being used for experiments. The results are given in the following 
table.

Live scale on unsnrayed -oeach trees at Port Valley decreased 15 -oercent 
between January 13 and March 3. This is believed to be due chiefly 
to the twice- stabbed ladybeetle ( Chilocorus bivulnerus Muls.). rather 
than to cold weather, as we have shown heretofore that a minimum tem- 
perature of 16° E. will not kill the San Jose scale on oeach trees in 
Georgia. The minimum temperature recorded at Port Valley during the 
winter was 15°; however, this has been one of the coldest winters on 
record, not because of the unusually low temperatures but owing to a 
number of long periods with daily mini mums below 32 . 
C. H. Alden (March 23): There is good control of the scale in 
well-sprayed peach and apple orchards at Cornelia, but from moderate 
to severe infestations have been observed in unsprayed or poorly 
sprayed orchards. 
Ohio. T. H. Farks (March 25): An examination made March 25 showed a high 
mortality at Columbus. ' 7 inter temperature reached -17° F, , and only a 
very few of the insects survived.
