-447- 
cnntral Missouri have consistently shown a rather heavy nut. weevil in- 
festation. Nuts being get he red" at this time show approximately a 5- 
percent infestation and it, seems to be a little lighter on most trees 
than during the last few years. The hickory nut crop, however, is very 
heavy, which may account for the apparent reduction in percentage of 
nuts infested, 
WALNUT 
WALNUT HUSK FLY (Rhagoletis complete Cress. ) 
California. D. W. Tubbs (October 19): At the suggestion of D. B. Mackie, 
I report the finding of the walnut husk fly in Orange County. This 
is the first year this insect has been reported on the coastal side of 
the foothills lying between Orange' County and the former area of infesta- 
tion in Los Angeles and San Bernardino Counties. Specimens have been 
found across the north and northeasterly section of the county, particu- 
larly in the eastern and native black walnuts', and also in several com- 
mercial plantings of the Persian walnut. 
H. J. Ryan (October 21): All of the Eureka variety of walnuts 
known to be infested in Los Angeles County, and most of the Placentia 
variety were sprayed. Control was satisfactory and, as compared with 
last year, was excellent. 
WALNUT CATERPILLAR ( Datana integerrima G. & R. ) 
Virginia. H. G. Walker and L. D. Anderson (October 26): The walnut datana 
was abundant on many walnut and hickory trees at Norfolk during the 
summer. 
Minnesota. A. G. Ruggles (October 18): Reports' numerous in September. Not 
quite as abundant , however, as in 1936. 
Oklahoma. F. A. Fenton (October 19): The second brood of the walnut datana 
completed defoliation of pecan and walnut trees several weeks ago and 
some trees are beginning to put out a late crop of leaves. 
CITRU S 
CALIFORNIA RED SCALE ( Chrysomphalus aur^.ntii Mask. ) 
Texas. S. W. Clark (September 20): Causing serious damage to citrus in the 
Mission-Edinburg section in western Hidalgo County. 
California. H. J. Ryan (October 21): Considerable control work was done in 
August and September and by the first of October a great many groves in 
Los Angeles County that were thought to be in excellent CDnditi^n 
following spring and early summer treatmjnt were carrying an extremely 
heavy population, which means that a. great deal of late fall and early 
spring control work will be necessary.
