and the possibilities of control or repressive measures. The work 

 has been placed in charge of D. B. Young, who was temporarily 

 detailed from the Entomologist's office. Hall B. Carpenter of 

 Somerville, Mass., was also engaged as a special assistant for thi;- 

 work. Data in regard to a large number of fields have already been 

 secured and much material collected which will be duly classified at 

 the close of the active season. Results so far obtained clearly indi- 

 cate a considerable difference in habits in New York State as com- 

 pared with the infested areas of Massachusetts. These variations 

 are of much practical importance because of their bearing upon 

 quarantine restrictions or other methods designed to prevent further 

 spread, A detailed report upon this work can not be completed for 

 some months. 



Early in July 1919, the Entomologist was appointed collaborator 

 of the Bureau of Entomology, United States Department of Agri- 

 culture, and specifically authorized to investigate corn borer control 

 in the states of New York and Massachusetts, He was also 

 appointed chairman of a subcommittee on the European corn bore-, 

 subsequently changed to a subcommittee on insect control, of the 

 committee on policy of the American Association of Economic 

 Entomologists and a member of a special committee appointed at 

 the Albany-Boston conference on the European corn borer. He has 

 in these various activities been able to exercise a marked influence 

 upon both state and national phases of the situation. He has felt 

 compelled to do this because the insect is one of national importance 

 and measures adopted in one commonwealth must be contingent to a 

 greater or less extent on those enforced in other states or pressed 

 to a successful conclusion by the representatives of the federal 

 Bureau of Entomology. A detailed account of the investigations 

 and activities in relation to this recently introduced pest may be 

 found in the Entomologist's report. 



Other corn insects. The great interest in the European corn 

 borer caused most careful and repeated examinations of corn 

 throughout the State and one outcome was the finding and reporting 

 of a number of injurious species. The lined corn borer, hitherto 

 supposed to be rare in New York State, was found to be rather 

 widely distributed and frequently injuring a considerable proportion 

 of the com on recently turned sod. 



The well-known stalk borer, a generally recognized pest in a 

 variety of thick-stemmed plants, caused numerous complaints, 

 though in most cases the injttry was by the corn ear worm. This 

 last was in not a few cases thought to be the European corn borer.
