118 STATE BOARD OF AGRICULTURE 



A trip was made, in company with Professor Wheeler, to the sub- 

 station at Cliatliani, in Alger county, upper peninsula. Collections of 

 insects were made at the station grounds and in that vicinity, and, 

 so far as possible, the insects collected were determined and listed, 

 nuiny records of importance being thus obtained. The more serious 

 pests were selected and accounts of each given with measures for 

 their destruction. These lists and accounts were published in Bulletin 

 No. 180, Besides the work on insects, over thirty photographs were 

 made of the growing crops, showing their condition in the tield. On 

 the way back, a stop was made at Beaver Island in Lake Michigan, 

 where a brief survey of the same character was made. 



The work on sugar-beet insects of the State has always been kept 

 in mind, and all cases of injury to this crop have been given special 

 attention, in order to gain as intimate an acquaintance as possible 

 with the enemies of this new staple. 



Several new scale-insects have been recorded from the State, all of 

 considerable importance, and one old species, which was found some 

 time ago, and which has become quite prominent in limited districts. 

 Work on these pests is steadily going forward, in hopes of finding some 

 new points that may be turned to account. 



Many articles on insects and their control have been written for the 

 agricultural periodicals and newspapers, where it seemed desirable to 

 get information quickly before the public. 



It is hoped that in the near future, a place may be provided for the 

 study of noxious insects, such insects as scales, where they may be stud- 

 ied and experimented with in safety. It is not considered advisable to 

 introduce such insects as San Jose scale or the European fruit-scale on 

 our trees here for fear that they may become general. A small green- 

 house would enable us to grow small trees in gauze cages in safety. 



Such "insectaries'' have been found very efficient in other states, and 

 one could be used to great advantage here.
