EUROPEAN WHEAT MIDGE 
A survey of the European wheat nidge ( Thecodiplosis mo se liana 
G-ehin) in western Washington was made in July.' The survey extended 
the known infested area to Puyallup, in Pierce County, nearly 50 miles 
south of any previously known infestation. A number of heavily in- 
fested fields were found in the older infested district near Burling- 
ton, in Skagit County. In one field of spring- sown wheat it was esti- 
mated that over 5Q .percent of 'the wheat kernels had been destroyed. 
The infestation in Snohomish, King, and Pierce Counties was very light. 
The insect has spread through Snohomish and King Counties into Pierce 
County, notwithstanding the scarcity of wheat. In some places the 
small wheat fields, are 18 miles apart. South of Puyallup conditions 
are more suitable for .rapid spread of infestation. (M. M. Refiner,

MORMON CRICKET 
The mormon cricket outbreak in 193& was .as severe as, or v/crse 
than, in 193 5» Snne reductions in size and intensity of infestations 
were noted in Montana, Idaho, and Washington, but these were more than 
offset by increases in the other States, In addition to the eight 
States infested in 1935. small infestations were reported in California, 
North Dakota, and South Dakota. Considerable damage to crops was 
recorded in most of the States affected, although the losses were small- 
er in States where control work was carried on. Montana, where little 
or no control work v/as done, showed an estimated loss in grain for the 
Crow Indian Reservation alone of $200,000. Utah reported losses to cattle 
range and crops of $6U,000 and Nevada, where a thorough control 
program was carried out, reported only $1,000 loss to crnps > with a 
saving of $250,000, although damage to the range in some sections was 
quite severe. The crop losses reported in Washington and Idaho were 
also very low, compared to what they might have been had no control 
work been carried on. No estimates were made for Wyoming, Oregon, 
or Colorado. Only three States — Idaho, Nevada, and Washington — 
put on control campaigns in 193°* These were financed, for the most 
part, by W. P. A., E. C. W. , and State funds. A total of 103,600 
acres of cricket- infested land was treated in the three States, as 
follows: Idaho, Uo.OOO; ' Nevada, Sl.OOO; and Washington, 2,600. 
In addition, 11 miles of barrier were used in Idaho and 2H miles in 
Nevada. It was estimated that 300,000 bushels of crickets wore trapp- 
ed and destroyed in the latter State. From estimates submitted by the 
entomologists of the various States affected the following acreages 
were found to be infested in 1936: California, Uo,000 (?.); Colorado, 
4U0.000; Idaho, 1,295,580; Montana, 1,029,000; Nevada, l,lU2,7o8; 
Oregon, 16^,700; Utah, 50U,500; Washington, 135,000; Wyoming, 856,196; 
total 5,607,7Uh. (f. T. Cowan, Bureau of Entomology and Plant Quar-
