GREEH PSACH APHID ( Myzu s persicae Sulz.) 
California. E. 0. Essig (February 26): Because of the mild winter, aphids 
have survived in considerable numbers in the San Francisco Bay area. 
The green peach aphid has been abundant at Berkeley. Adults of the 
black peach aphid (Aphis persicae-ni/^er Smith) have been noted on 
peach trees that have held their leaves all winter* 
RASPBERRY 
RASPBERRY CAME BORER ( Oberea bimaculata Oliv. ) 
Utah. G. P. Xnowlton (January 10): The following letter was recently re- 
ceived: "While pruning raspberries I noticed some of the new canes 
fell over. On examination, I found in various canes, but principally 
in the weaker ones, larvae ranging from about 3/l6 to 2 inch long. 
The smaller ones were white, whereas the larger ones were dull white 
with dark heads. The larvae entered and worked in the canes from 1 
to S inches above the ground." 
GRAPE 
GRAPE LSAFHOPPER ( Erythroneura comes Say) 
California. S. Lockwood (February 25): The grape leafhopper was over- 
wintering in considerable numbers in sections of the San Joaquin 
Valley. Reports state that the excessive rainfall of the last 2 weeks 
has apparently reduced the numbers markedly. 
PSCAIJ , 
OBSCURE SCALE '( Chrysomphalu s obscurus Comst.) 
California. M. L. Jones (February 25): The foci of known infestations in 
C a lifornia are limited to Pacoima, Los Angeles County, and the vicinity 
of Flinn Springs, San Diego County. The infestation is found only on pecan 
trees. 
WALNUT 
FROSTED SCALE ( Lecanium pruinosum Coq.) 
California. H. J. Ryan (February 21): Infestations on English walnut trees 
in the Pomona district became so severe during the winter that about 
250 acres of walnut orchards were sprayed with oil in January. This 
scale has been well established for many years in southern California, 
but this is the first record of any build-up to population requiring 
treatment.
