PE/S 
PEA APHID ( Illinois pisi Kalt • ) 
California Roy E. Campbell (April 15): Practically the entire 2,150 acres 
of cannery peas in Stanislaus County are seriously infested with 
the pea aphid. For two weeks there has been a heavy flight of 
winged adults. Mild infestations are found on most of the peas ^ 
in the Santa Clara Valley, and sore late plantings are now becoming 
badly infested. 
Kansas J. W, LcColloch (April 24): The pea aphid has made its appearance 
again in this State, and is causing damage to alfalfa in the vicinity 
of Topeka, Kans . A survey of conditions made yesterday showed that 
in one field approximately 20 acres are severely injured, and that 
the aphids are spreading to adjoining fields. Pea aphids were 
also noticed on garden peas near these alfalfa fields, and it is 
possible that there is sore association between their presence on 
garden peas and the alfalfa. This is a rather large trucking^ 
district, and peas are grown quite extensively. Dr. R. C. Smith, 
who made the survey, was inclined to think that the damage tc 
alfalfa might be associated with this, since we have had no other 
reports of pea aphid injury to alfalfa in the State this year. 
SPINACH 
APHIDIDAE 
California Roy E. Campbell (April 15): All seven canneries in the Santa Clara 
Valley stopped canning spinach yesterday because there were so many 
syrphid larvae in the spinach which it was impossible to remove in 
the washing process, and have got into the canned product.
