February, '21] gossard and parks: hessian fly prevention 53 



Within the state systematic pest reporting from all sections offers 

 additional advantages in enabling immediate action to be taken by the 

 entomological staff' in the case of insect injury about which the}^ have no 

 pre^'ious information. It also enables them to send outlines of the life 

 histories and control measures of the common insects to representative 

 growers in every county, a feature which will result in as extensive and 

 desirable a form of entomological education as could be worked out. 



President Wilmon Newell: Is there any discussion"- 



Mr. E. p. Felt: I believe a volunteer pest reporting service is of 

 material value in assisting in the detection of recently introduced 

 insects, though I cannot support this by facts. About 20 years ago, the 

 speaker had a similar service and two of these voluntary observers, as 

 we called them at that time, are now active, energetic entomologists. 

 I do not know whether they started with the voluntary pest service or 

 not, but one of the things that we need to develop throughout the coun- 

 try is a more general appreciation of scientific work and more general 

 cooperation, not only on the part of entomologists, but agriculturists, 

 foresters, and laymen in general. We must secure the s>Tnpathy and 

 cooperation of the latter, and in doing that, we will immensely increase 

 our efficienc}-. I believe this is an activity that has not been given 

 sufficient attention in many places. 



AIr. W. E. Hinds : I would call attention to the Mexican Bean Beetle 

 situation in i\.labama as an instance where a voluntary pest reporting 

 service failed. This insect came to the attention of a county agent in 

 Alabama a year before it was reported to the Experiment Station, 

 because he failed to appreciate its importance. He recognized the insect 

 and had some printed information concerning it, but failed to report. 



Mr. W. R. Walton : I have had considerable experience with volun- 

 tary crop pest reporting service. A great many of the Federal reports 

 are received in the Bureau of Crop Statistics and are referred to our 

 office. They are usually 30 days late and do not give information quick 

 enough to be of material use. 



President Wilmon Newell: The next is a joint paper by H. A. 

 Gossard and T. H. Parks, on the "Value of Entomological Service to the 

 Ohio Farm Bureaus in Their Efforts to Control the Hessian Fly." 



HESSIAN FLY PREVENTION 



B\' H. A. Gossard and T. H. Parks 



For many years, the standard recommendation of entomologists to 

 prevent Hessian fly injury has been to seed late. All have assumed the 

 advice to be good and Hessian fly has been cited perhaps, more frequently
