-1*8- 
Oklahoma. F. A. Fenton (March 20) : On March 11 a trip was made to the wheat 
sections of north-central Oklahoma, in Garfield and Kingfisher Counties, 
and on March 18 to sections of Noble and Payne Counties. The green hug 
is present in only a few fields and is apparently in about the same 
condition as it was last January. No further killing of plants has been 
noticed, and the infestation is very spotted. Parasites are also present 
in a few pla.ces. We do not anticipate serious trouble from this pest 
this year. 
ALFALFA 
ALFALFA WEEVIL (Hyper a postica Gy 11.) 
California. A. E. Michelbacher (March 22): On March 15 the weevil was 
abundant in a single field in the San Joaquin Valley near Patterson, 
where an average of 197 larvae and 35 adults were collected in 100 
sweeps of an insect net. In other fields examined the larval count was 
generally less than 30 P er 100 sweeps. In the San Francisco Bay dis- 
trict on March 18 the highest average larval count per 100 sweeps was 
158. In other fields examined it was below 25. At Pleasanton on 
March 18 only 3 larvae and 1 adult were collected in 600 sweeps. Adults 
of Bathyp lectes- curculioni s Thorns, were found throughout the infested 
region. In the San Francisco Bay district a high percentage of the 
alfalfa weevil larvae were parasitized, while in the most heavily in- 
fested field in the San Joaquin Valley a smaller percentage appeared to 
be parasitized. The weevil population is much lower than a year ago, 
when counts of 1,000 or more were not uncommon; however, the alfalfa was 
more advanced than it is this year. 
LEAF BEETLES ( Biabrotic a spp. ) 
Oregon. B. G. Thompson (March 3) : 5> soror Lee. is numerous and damaging 
. young clover in the Willamette Valley. 
California. J. Wilcox and M. W. Stone (February 3): The following chrysome- 
lid beetles were taken on alfalfa near Alhambra, Los Angeles County, in 
their order of importance: B. soror , B. bait eat a Lee. , Gastroides 
cyanea Melsh. , and B. trivittata Mann. 
S. Lockwood (March 27): The 12-spotted cucumber beetle (B. duo - 
dec impure bat a F.).is numerous in alfalfa fields in Imperial County, in 
the southern part of i;he State. 
PEA APHIB ( Illinoia plsi Kalt. ) 
California. S. Lockwood (March 27): The pea aphid is more than ordinarily 
numerous in alfalfa at Bard, Imperial County, in the extreme south- 
eastern corner of the State,
