In all. of these infested fields' the ladybird beetle 
Hippodamia convergens Guer. has developed an enormous 
abundance and is doing wonderful work in the natural 
control of the aphid. 
M. H. Swenk (July 1-15): As stated In my special report, 
dated July 3 S the Nebraska outbreak was on the wane over 
most of the infested areas by July 1. The last reports 
were sent in on July 7. These related mostly to infestation 
in oats, and to a less extent in spring wheat, spelt, and barley, 
in the block of counties including Madison, Antelope, Holt, 
Wheeler, Greeley, Valley, Garfield, Loup, Rock, and Brown. 
In the western area the last complaints were received from 
Lincoln County on July.l, from Scotts Bluff County on July 2, 
and from Keith County on July 7. 
C. P. Gillette (July 21): The green bug is very abundant 
in eastern Colorado. From Cheyenne County north on late- 
sown grains, More serious than for many years. 
ENGLISH GRAIN APHID ( Macro s iphum gr anarium Kby. ) 
G. G. Schvcis (July 16): Very abundant on fields of spring 
wheat in Lyon and Washoe Counties, apparently causing some 
dwarfing of heads. Ladybird beetles are very abundant and 
apparently will clean them up. 
SMUT BEETLE ( Phalacrus politus Melsh. ) 
M. H. Swenk (June 15-30): The smut beetle (P halacrus 
poli tus) was reported as abundant in fields of smutted

PALL ARMYWORM (Laphjvgma frugioerda S. & A. ) 
"The News & Ol.-ervor" (July 7): County Agent N. M. Smith 
has discovered heavy infestation of the armyworm on more 
than 50 farms in Onslow County. 
J. R. Watson (July 18): The last days of June and the 
first days of July v/itnessed the heaviest infestation which 
Florida has experienced since 1912. The worms were trouble- 
some in areas ranging from the Everglades to extreme western 
Florida, although not present in all communities between. 
They attacked mostly grasses. Damage was extensive to late- 
planted corn, cotton, and peanuts. By the 12th of the month 
they had pupated in central and southern Florida, and a few 
days latex* in western Florida, Moths began to emerge on 
July 19 and therO' are prospects for a second brood soon.
