TWENTY-SEVENTH REPORT OF STATE ENTOMOLOGIST 19 



came from a direct appropriation administered through the 

 medium of the Bureau of Entomology and Plant Quarantine. 

 This allowed a change in the method of obtaining labor. The 

 most costly item in cricket control is the labor involved, and 

 stress was placed on increasing the use of barriers and power 

 dusters. Hand dusters in use decreased from 1,298 in 1937 to 984 

 in 1938, power dusters increased from 11 to 100, and metal 

 barrier from 54.8 miles to 156. Savings during the 1938 cam- 

 paign were estimated at $979,345. and losses at $96,304. 



It is much more difficult to anticipate possible cricket dam- 

 age for the next year than is the case with grasshoppers. We 

 are, however, better prepared for a campaign next year than in 

 the past. The following equipment is being carried over for 

 next year's campaign: 40 tons sodium arsenite, 88 tons diatoma- 

 ceous earth, 4 tons hydrated lime, 110 tons mixed dust, 48,407.5 

 gallons crude oil, 1,296 usable hand guns, 103 power dusters, 

 and 159 miles of metal barrier. The Federally owned part of 

 this material has been concentrated in a warehouse in Billings 

 and will be reissued to the counties in the spring according to 

 their needs.
