importance, since it makes possible the destruction of many borers 

 with practically no additional cost. 



The appointment of the Entomologist as collaborator of the Bureau 

 of Entomology, United States Department of Agriculture, specifically 

 authorized to investigate corn borer control in the states of New 

 York and Massachusetts, has been continued for the year beginning 

 July i, 1920. This has facilitated studies immensely and has enabled 

 the Entomologist to keep in close touch with developments in the 

 various infested areas and has also made possible closer cooperation 

 between the various federal and state agencies. 



The Entomologist has participated in a number of conferences 

 in Albany, Buffalo, St Thomas and Guelph, Ont., Boston, Mass., 

 and Washington, D. C, for the purpose of assisting in working out 

 methods of dealing with existing complications and the varying 

 conditions in different sections of the country. 



Late in the fall of 1920 the federal authorities started clean-up 

 operations upon an extensive scale in the more badly infested area 

 about Silver Creek, Chautauqua county, with the understanding 

 that the state authorities would cooperate in an educational campaign 

 to bring about better conditions in the more sparsely infested out- 

 lying sections. A brief statement of the situation with a series of 

 recommendations, which were indorsed at a conference of federal 

 and state officials at Buffalo, was prepared by the Entomologist and 

 has been widely distributed in the infested areas as Circular 199 of 

 the Bureau of Plant Industry, Department of Farms and Markets, 

 through the cooperation of farm bureau managers. The distribution 

 of literature was followed with public meetings and the utilization 

 of all available agencies in promoting the general adoption of 

 a modified type of agriculture unfavorable to the successful develop- 

 ment of the European corn borer. 



Quarantine regulations practically identical with those of 

 Massachusetts have been enforced in the New York areas by both 

 federal and state authorities despite the fact that although the insect 

 has been carefully studied for two seasons in New York State, it 

 has been impossible to find it habitually breeding in anything but 

 corn and very rarely has the borer been found in the stems of other 

 plants and then only when they were in the immediate vicinity of 

 corn. The marked difference in this respect between eastern 

 Massachusetts and the New York territory has led the Entomologist 

 repeatedly to question the advisability of maintaining such a strict 

 quarantine in sections where the borer produces but one generation 

 as compared with those where at least a partial second brood is the
