t of ore found in Nebraska by us, has been reported furing the same 
period. This infestation and injury seem most severe in Hitchcock 
and Red Willow Counties, but extend nort to Dawes County. 
A WIREWORM (l lcnocremflius vespertinus Fab. ) 
North J. N. Tenhet (August IS): A month ago this click beetle was present 
Carolina in large numbers in leaf sheaths of corn, and could be readily taken 
at trap lights. At this date, however, they are becoming very scarce 
and are difficult to find in any numbers. Evidently the period of 
adult activity is about at an end for this season. 
Nebraska M. H. Swenk (July 25-August 2S) : Curing the first week in August an 
abundance of beetles of the southern corn -ireworm Konocreoidius 
vesnertinus './as reported from a cornfield in Cloy County. 
MHZ';; OR I '.S (El at er i dae ) 
Missouri K. C. Sullivan (July 23): It seems that '.-ireworms are causing mere 
than ordinary injury to corn, especially in southern Missouri. 
SEED CORN BEETLE ( Agonoderus pallipes Fab. ) 
Nebraska H. H. Swenk (July 25-August 25): There has been an abundance of the 
seed corn ground beetle in certain cornfields in eastern Nebraska 
during the present season. 
AT,? ALFA 
PEA APHID ( Illinois pi si Kalt. ) 
Idaho C. VJakeland (July 2 9): Daring the past seasons the pea aphid has 
been of greater or less abundance in nearly all alfalfa fields. In 
a few fields in the past it has been observed in countless numbers 
but the alfalfa had made good growth before the infestations became 
Large and no special injury could be attributed to it. This season 
alfalfa plants became heavily infested while they were still small, 
growth of alfalfa was slow, owing to the cool weather, and the aphids 
killed back the first crop completely in many fields and retarded 
second growth. In two instances growers applied granular calcium 
cyanide and report that they are well satisfied with results, for 
they obtained a first cutting of alfalfa which more than paid for the 
expense of the treatment. Parasites were c iuite numerous in the in- 
fested fields from the start and before the first crop was ready to 
cut they had almost completely destroyed the aphids. Lady beetles, 
an undetermined species of syrphus fly, and Wo undetermined soecies 
of hymenopterous parasites were of greatest importance. It was inter- 
esting that control would be established in one field by lady beetles, 
in another by syrphus flies, etc. , but that all species of parasites 
did not occur abandantly in the some field.
