OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES EOH OCTOBER, 1929. 
Unusual numbers of grasshoppers appeared late in the season in the 
western Great Plains States and the northern Rocky Mountain region, and 
considerable apprehension is felt as to the outlook for next year. 
The Hessian fly seems to be decidedly more numerous in southern Iowa 
and Nebraska, Illinois, and Missouri than for the past few years. Nebraska 
reports that a new outbreak is starting in the southeastern part of that 
State, and a general outbreak is reported from Missouri. 
The fall armyworm continues to be reported as destructive in the 
Southern States. It destroyed many acres of winter spinach in the Norfolk 
district of Virginia and it completely destroyed newly-seeded alfalfa at 
one locality in Mississippi. 
The clover seed midge has been seriously reducing seed yields in 
many districts in southern Idaho, and the clover head caterpillar is doing 
considerable damage to the seed crop in parts of Nebraska. 
The pear psylla has been reported foa? the first time as a serious pest 
in southwestern Illinois. 
Very considerable injury by the oriental fruit moth is reported from 
the Middle Atlantic, Southeastern, and East Central States from New Jersey 
to Georgia, and from Michigan to Tennessee. 
The plum curculio is going into hibernation in phenomenally large num- 
bers in Georgia and Tennessee. 
The numbers of the walnut husk fly have been very materially reduced in 
the Chino-Pomona district in California by the practise of control measures. 
No field infestation of the Mediterranean fruit fly was found in Florida 
or elsewhere in the United States during the past month, nor were any adults 
of this insect collected in traps. 
The citrus whitefly seams to be quite generally troublesome in the 
gulf section from Florida to Mississippi.
