PEA APHID (Illinois pisi Ko.lt.) 
New York.. ..IT. Y. State. Coll. Agr. News Letter (July): The pea aphid was 
wry ■• abundant /throughout the State. In some areas as high as 95 per- 
cent of : the" late peas were plowed under. In the lake region this 
insect is more serious than it has been in any past year. (Abstract 
J.A.H.) 
Idaho. C. Wake land (July 2k) : There is a rather serious outbreak in the 
pea fields of northern Idaho. It is especially severe on the late 
varieties, and yields are being definitely reduced. This unusual in- 
festation is doubtless due to the preceding mild fall and winter, which 
allowed volunteer peas to live in the field throughout the winter and 
early spring, and aphid s probably reproduced on them during the period 
'vhen they are usually dormant in this area. Pa.rasites have been of 
minor importance in control and have not bred up as they have done 
frequently in former years when the aphid has been abundant. 
CABBAGE 
HARLEQUIN BUG ( Murgantia histrionica Hahn) 
Virginia. H. C-. Walker (July 26): The harlequin bug is only moderately 
abundant at Norfolk. We have had very few requests for information, 
as compared with last year. 
Florida. F. S. Chamberlin (June 20 to July 15): The harlequin cabbage bug 
is very abundant at this time in Gadsden County, attacking cabbage e.nd 
collards. 
Ohio. N. F. Howard (July): The harlequin bug is present in southern Ohio 
but is not very injurious. A number apparently survived the rather 
severe winter. 
3. J. Laniis (July 23): An adult was taken from broccoli at the 
State University. This is the first record this year for Columbus. 
Indiana. J. J. Davis (Jul;/ - 23): The harlequin bug was reported as destruc- 
tive to cabbage and cauliflower from July 2 to 12 in the southern part 
of the State. 
Tennessee. G. M. Bentley (July 21): The harlequin bug is very abundant 
throughout the Sta/te, except in 8 counties in the extreme western part. 
CABBAGE APHID ( Brevicoryne brassicae L.) 
Ohio. T. H. Paries (July 10): The cabbage aphid has caused serious injury 
to some commercial cabbage plantings. Damage is most serious on cabbage 
grown from plants produced in the South. 
Indiana. J. J. Davis (July 28): The cabbage aphid was reported as heavily 
infesting cabbage at Howe and Indianapolis the last of June.
