Nevada. G. G. Schweis (April 24): Alfalfa aphid reported as damaging alfalfa 
fields in Washoe and Douglas Counties* 
Washington. R. D. Eichnann (April l4): Pirst damage in 10 years reported from 
Gardena, Walla Walla County. Two large alfaifa fields affected. Heavy 
populations in most fields in the vicinity. Pirst cutting ruined* Winged 
forms migrating from this vicinity, and found in all alfalfa around Walla 
Walla. Many apparently immigrants. Erosion-control alfalfa near future pea- 
fields yields winged immigrants. (April 2l): Survey of 72 fields in 8 
southeastern counties revealed only 1 concentrated hay— producing district of 
about 12 sections in Walla Walla County as suffering damage. Two other 
small isolated fields in Grant and Richland Counties showed damage. 
Oregon. M. M. Reeher and L. P. Rockwood (April 15) i Very few on alfalfa in .the 
Willamette Valley in October 1938, and November 1938 was colder than normal. 
Scarce in early spring, indicating few eggs laid on this host in the fall of 
1938. Pirst mature stem mother observed on March 22. Despite favorable 
weather conditions since March lo, populations on alfalfa still low in most 
fields seen. Most fall populations seen on vetches and Austrian winter 
field peas in the - Willamette Valley moderate at the beginning of the winter, 
continuing low through the winter. Rapid increase since March 15 on all 
early fall-sown annual legumes. Alates very scarce now and no signs of 
movement into late fall-sown vetches or peas yet observed. Coccinollids 
and syrphids more abundant than last year but dry weather has kept dawn

Arizona. L. L. Stitt (April ~j)t Newly emerged adults of L. elisus hesperus Knight 
and L. pr at ens is obi: ) aoatus found on alfalfa in nearly every .field examined 
in Yuma County. Nymphs present are mostly in the fifth instar. Observations 
indicate the first generation for 1939 as nearly completed. Eggs well de- 
veloped in a few adults. A number of blasted buds, typical damage, found in 
one field where the population was over one bug per sweep. 
W. A, Stevenson (April 22): Sweeping records showed some increase in 
populations in Pima County, L. pratensis oblineatus predominating to date.
