A1FALFA 
ALFALFA WEEVIL ( Hyp era -postica Gyll.) 
Nevada. C-. G. Schweis (April 20): The alfalfa weevil is moderately abundant 
Reno and Fallon. Oviposition has started although the temperature is below 
normal. 
California. A. E. Michelbacher (April 20): Throughout the infested area there 
ha-s. teen an increase in the number of larvae collected. The heaviest infes- 
tations are apparently around Pleasanton. Rather large numbers of the larvae 
have also been collected in the Niles and Tracy a r eas. In the fields which 
have received but little care some damage has been done but for the most part 
it has been very slight. At the present time larvae of all stages of al- 
opment can be collected. Egg laying is still going on, and adults of the i 
generation have been emerging for some little time. 
ALFALFA WEB WORM ( Loxostege commixtalis Walk.) 
Colorado. G. M. List (April 25): Moths of the alfalfa webworm began to appear in 
limited numbers in the more southern part of the state early in April. Some 
have been noted flying in the Fort Collins section during the last few days. 
The height of the flight will probably occur about the middle of May. I 
overwintering forms are very numerous in the soil in many sections' of the 
eastern half of the state. In some fields the population averages from 2 to 
4 per square foot. 
CLOVER LEAF WEEVIL ( Hyp era punctata Fab.) 
Utah. G. F. Knowlton (March 25): An adult clover leaf weevil was found in 
hibernation under a rock in the foothills east of Logan, about 1 mile it or: 
nearest alfalfa field. 
PEA APHID ( Illinois pisi Kalt.) 
Virginia. H. G. Walker (April 26): The pea aphid is becoming very abundant and 
injurious on alfalfa and is beginning to migrate to peas. 
Mississippi. C. Lyle and assistants (April): 'The pea aphid was first observed 
April 16 at Pascagoula on peas. It is also reported as very abundant on 
English peas at Ocean Springs. (Abstract, J.A.K.) 
Kansas. H. R. Bryson (April 23): The cold, dry weather in Kansas -apparently was 
conducive to the development of the pea aphid. Reports of injury to alfali 
have come from Newton, Kerington, Cottonwood Falls, and Manhattan. 
California. A. E. Michelbacher (April 20): The pea aphid on alfalfa increased 
to cutting of the first crop. This pest was very abundant around Ver .1 
and quite numerous in some fields about Tracy. 
A PLANT BUG ( Thyanta puctiventris Van T.) 
Utah. G. F. Knowlton (April 4): This pentatomid is .Abundant on an alfalfa s« I 
farm at Deseret, causing the farmers some concern.
