Colorado C. P. Gillette (May 27) . "While we have noted the overwintering of this 
aphid for many years on alfalfa plants in protected places on college 
campus at Fort Collins vfe have never Imown it to be atundant enough to 
attract the attention of farmers until this spring. On May 4 a portion 
of an alfalfa plant having upon it a considerable number of coccinellid 
larvae was received trom a stoci: farm near Westminster just north of 
Denver. The statement was made that many acres of alfalfa on this farm 
were turning brown and dying from the attaclcs of these "Worms", Mr. C. L 
Corlans, of this office, was sent to investigate the trouble and found 
the damage due to the pea aphis. A few other fields, where some damage 
has been done, have been foxmd, but the damage has not been extensive. 
On the college campus there are small patches of alfalfa on the south 
side of buildings that have been 3d.lled down by this louse. The im~ 
usual presence of this insect this spring is probably due to the mild 
winter which has permitted an abnormal number of the lice to stirvive 
the cold weather. '■■ 
Oregon L. P. Bociwood (June 11) . "Only one field in the vicinity of Forest Grove 
has been seen which was seriously injured. This was in vetch and the 
damage estimated at about 50 per cent of the crop. This was a field con- 
sisting of 5 acres of early fall sowing. Several coccinellids and 3 
species of syrphus flies have eaten about 75 to 80 per cent of the 
aphids. This field is bordered throughout its entire length by an early 
spring sown field of the same variety of vetch which was not at all in- 
jured; patches of purple vetch stood out prominently in the injured 
field and these plants were not injured by the aphids." 
A. L. Lovett (June 17). "This insect is generally reduced in numbers, or 
has disappeared from the fields at this time. Natural enemies are re- 
sponsible for 80 per cent of the decrease. Five species of coccinellids 
and three species of syrphids are the main parasitic forms. Serious in- 
jury on vetch in Western Oregon is confined to an occasional early sown 
field, or volunteer field. Injury is more severe on peas and alfalfa 
in Umatilla County (Dean) but decreased abundance of aphids and injury 
is evident since the middle of May. ' 
ALFALFA WSER^OEM ( Loxostege similalis Guen. ) 
Colorado C, P. Gillette (May 22) . "Moths have been received from different local- 
ities beginning early in May and indicating that this insect will be 
common and pcjssibly very abundant over much of the alfalfa growing terri- 
tory from Roclsy Ford in the lower Arkansas Valleytto Port Collins.' 
SUGAR BEST VTSB^ORM ( Loxostege sticticalis L. ) 
Colorado C. P. Gillette (May 22). "Moths were flying in moderate numbers to lights 
in northern Colorado on May 20. Complaints of injury to new seedings of 
alfalfa in the Port Collins district are also being made."
