During the epidemic of Spanish Influenza last fall, a very interesting 

 and efTective campaign against house-flies was carried on by the depart- 

 ment under the direction of Doctor Chandler. During this campaign the 

 attempt was made to kill by formaldehyde, as many flies as possible in 

 the mess-halls, in the hospital wards, in isolation hospitals; and, by 

 poisons and sprays, in their breeding places — the most notable being 

 the piggery. It was comforting to note that the number of new cases 

 dropped in a very gratifying manner immediately (that is the day after) 

 operations were instituted, and so great a proportion of our supply of 

 flies was destroyed that up to the middle of the following June (1919) 

 the comparative absence of flies was noticeable. 



Mr. Don B. Whelen, Extension Specialist in Insect Control, has re- 

 signed to take up work in the commercial field, his resignation taking 

 effect on June 30th. Mr. Whelen was, at the time of leaving, engaged in 

 directing a general campaign against grasshoppers in Antrim, Benzie, 

 Charlevoix, Cheboygan, Crawford, Emmet, Grand Traverse, Kalkaska, 

 Manistee, Missaukee and Roscommon counties, where grasshoppers have 

 destroyed a great deal of wealth in the form of crops for two or three 

 years past. 



Mr. Edwin Ewell, Extension Specialist in Apiculture, has carried in- 

 formation of great value to the apiculturists and has, during the yesir, or- 

 ganized the beekeepers into country clubs, in 14 counties. 



Our practice of answering queries by correspondence seems to be ap- 

 preciated by the people of the State. During the month of June besides 

 a large mass of routine mail to companies and individuals, the writer 

 replied to 72 letters from county agents in reply to requests for expert 

 advice. 



The last legislature increased the appropriation for State Apiary In- 

 spection from $3,000 to $10,000, thus making it possible to increase the 

 quantity of work done. Further information will be supplied in the 

 report of the State Inspector of Apiaries. 



Respectfully submitted, 



R. H. PETTIT, 

 Professor of Entomology. 

 East Lansing, Mich., June 30, 1919.
