(May l) : Larvae of this species are doing the normal amount of 
damage to the wheat in the Big Eend Region this spring . Damage by 
the larvae to spring wheat is normal in all fields, owing to cool damp 
weather the last two weeks . Loss from wireworais of this species 
averages at this time 10 to 20 per cent of thes total plants that 
sprouted, and the damage is continuing. There is no difference in 
damage between fields with wet formaldehyde smut treatment and fields 
treated with dry copper carbonate, though there is more stand and 
thriftier wheat in the latter fields dry treated. Damage will continue 
till the weather warms up and the ground dries out down to the wheat 
crowns , 
Adults cf this species have appeared the first week in May for the 
last three seasons and this year is no exception, a few being found 
today. The males are the only sex found in flight and these only for 
a week or two . 
Tb,is report applies to Lincoln, Adams, and Franklin Counties. 
IRRIGATION WIREWORM ( Pheletes sp.) 
Washington M. C. Lane (April 24 and 25): In atrip through the irrigated valleys 
adjacent to Ellensburg and Yakima, wireworms of this genus were found 
doing a little damage to spring grain. Damage was similar in every 
way to that done by wireworms of the genus Ludius under dry-land con- 
ditions. However, this wireworm seems to be more of a truck crop wire- 
worm and fieeds the whole season on several crops of this class. It is 
only found under irrigated conditions and thrives best in wet sour 
places in this section. Damage to growing tubers of potatoes by the 
feeding tunnels of this wireworm mounts into the millions of dollars 
every year in Yakima Valley. So far this is the worst insect enemy 
the farmers of this fast-gtowing truck crop section have to deal with. 
INFLATED WIREWORM ( Ludius inflatus Say) 
Washington M. C. Lane (April 24 and 25): In a trip to Kittitas and Yakima Counties 
this wireworm was found to be doing considerable damage to winter wheat 
on the high prairies near the timber. Wireworms of this species were 
collected at both Thorp and Tieton that had been killing the wheat for 
10 days past and were still at work, although the ground was becoming 
warm and dry. Good examples of damage done by spring harrowing of 
winter wheat were seen in thesd places. Places skipped in fields by 
the harrow showed fine stands of wheat, while the most part that was 
harrowed is thin, and the wireworms are fast finishing what was not 
hurt by the harrow teeth. Loosening up the ground in the spring gives 
the wireworms a much better chance of moving from plant to plant in 
drill rows and keeps them also nearer the surface longer. Some seed 
injury from the use of f ormald^yde for smut was also noted, and this 
in the past has been blamed wrongly in many cases to wireworms. 
FALSE WIREWORMS ( Eleode s spp.) 
Nebraska M. H. Swenk (April 15 - May 15): During the period covered by this 
report the Great Plains false wireworm continued to be the most seriously 
injurious enemy of field crops actively present in the State. The 
Cheyenne County infestation referred to in my last report continued to 
be the cause of complaints up to the latter part of April. This in- 
festation extended from around Sidney north to around Curley in that
