February, '19] GOSSARD AND PARKS: OHIO WHEAT SURVEY 63 



counties, expended $80.41. A third man who had the longest and 

 roughest route of any spent twenty-seven or twenty-eight days in 

 the work, looked over twenty-five counties, and spent $175. Six other 

 men participated in the work, in some cases spending only a day or two 

 in their home counties, in other cases surveying five or six counties; 

 but in these cases each county was a separate undertaking and dis- 

 connected with any other trip. 



The total cost of the survey of 1918, exclusive of salaries, was 

 $578.45. With the salaries and wages of all the workers included 

 the cost was approximately $1200. These expenses were born coop- 

 eratively by the Experiment Station, State University and the State 

 Department of Agriculture. 



Results of the Survey of 1918 



It is yet too early to fairly appraise the value of the past season's 

 work. Near the conclusion of the survey, potato aphis was encoun- 

 tered in damaging numbers in northern Ohio and spraying demon- 

 strations conducted as in the previous year. Investigations later made 

 by the Extension Entomologist over ten widely separated counties 

 revealed the presence of 65 to 80 per cent parasitism among Isosoma 

 tritici. The location of areas inhabited by chinch bugs has enabled 

 the Extension Entomologist to concentrate attention upon this insect, 

 while information about other insects collected by these trained en- 

 tomologists has been of much value in forcasting extension problems 

 which can be better dealt with in their incipiency. That we were 

 again able to allay the fears of our wheat growers regarding any dis- 

 astrous menace to the 1919 crop is part of the explanation for the in- 

 creased acreage put out the past fall, notwithstanding the shortest 

 labor supply we have experienced in many years. We were able to 

 definitely encourage increased plantings in northeastern Ohio and 

 hold out the hope of a reduced infestation from jointworm everywhere 

 in 1919. The location of the areas inhabited by chinch bugs has en- 

 abled our Extension Entomologist to concentrate attention on these 

 districts. We were again able to shoo away the Hessian fly bugaboo 

 sufficiently from more than half of the state to enable the farmers to 

 take advantage of all their available time. We will doubtless find 

 some neigh] )orhoods and sizable districts outside the territory where 

 we counseled caution that will produce too much fly because farmers 

 hurried their seeding a little too much, but we cannot now see any 

 state-wide threat to our next crop and believe the total harvest in 

 bushels next summer will be much greater than if we had held all our 

 growers back because of lack of definite knowledge.
