Arizona. T. P. Cassidy (April 27): Reports Were received during the t)ast 
week from Sacaton and the Salt River Valley that plant lice were 
causing serious damage to alfalfa. Inspections made in several alfalfa 
fields in the. Salt River Valley showed the infestation to be very 
heavy as literally thousands of plant lice could be collected in a net 
by sweeping the plants a few times. 
Nevada. R. A. Blanche rd (March): Periodic observations in western Nevada 
indicate the possibility of an outbreak of the pea aphid. The relative- 
ly mild and ep.rlv ■ spring weather has allowed viviparous forms to sur- 
vive in small numbers. During normal years winter temperatures are 
low enough to destroy green growth, preventing the anhids from passing 
the winter in any but the egg stage. The fields in the vicinity of 
Reno had green growth from 1/2 inch to 2 inches tall on March 22, and 
examination in six fields showed populations ranging from U to approx- 
imately 300 aPhids per five-clump sample. 
Oregon. L. P. P.ockwood (April 10); This species averaged 59 snhids per 
100 sweeps in a field of 'alfalfa' on high ground, showing good soring 
growth at New Era. Many were quite small and there were no alates. 
(April 13): In the Willamette Valley early fall-sown vetch, seeded in 
August or September, as cover crops, showed moderate infestations, as 
many as 350 enhids per 100 sweeps in some cases. Vetch fields, for 
hay or seed, seeded in October showed ver^ r few or no aphids. Two 
alates were swept from August-sown vetch, but none from October vetch. 
Coccinellid beetles, particularly Hipooc'gtnia convergens Guer. , are be- 
coming abundant in vetch 'fields. H. q ui nq u e s i gna t a oblioua Csy. and 
H. sinuata spuria Lee. began leaving their hibernation cache on April 
11 and are increasing in vetch fields. 
California. R. A. Blanchard (March): An outbreak on alfalfa appears 
probable in the Antelope Valle^ of southern California. The severity 
of this will depend upon weather conditions during the early p^rt of 
April. The populations are building up later than usual. There seems 
to be some correlation between this condition and the fact that very 
few severe frosts occurred during the early spring to prune back the 
alfalfa growth. The average temperature, however, has been sufficiently 
low to allow only slow growth of the plants. Such slow steady growth 
has been observed previously to result in slow accumulation of aohids, 
whereas periods of higher temperatures interspersed with frosts have 
resulted in earl^ infestations. The late infe static s la^e been ob- 
sc/vou Lo affect the alfalfa more adversely and cause a larger total 
loss of bay tha.n did infestations that occurred before the alfalfa had 
began to make sustained growth,

Louisiana. W. E. Hinds (April 27): Moths began emerging from overwintered 
larvae, in some numbers, following the rising of mean temperatures to
