 of the season. .Mr. A. L. Strand, wlio graduated from the entomolog^y 

 course of the collej^e in 1917. was also emplo}'ed and sent out to 

 direct the farmers in pest control. Two senior students, Mr. lorkins 

 and ]\Ir. King^. were also em])l(i\ed in this work at times. As a 

 result, the State was (juite well covered and all uf the nidst important 

 Outbreaks were \isited and ilie farmers in each instance were helped. 

 During the year the State entomologist prepared and delixered 

 at the annual meeting of the Amci"ican Association of I'xonomic 

 Entomologists, at Pittsburgh, I'a., an address entitled "Economic 

 Entomology in the Service of the Nation." This appeared in the 

 journal of Economic Entomologv. \*olume 11. pages ](i to <?T. 



COOPERATION WITH THE EXTENSION SERVICE 



The extension service of the college does not employ an ento- 

 mologist and it has not contribttted to the control of insect pests. 

 It has been the policy of the State entomologist's office to cooperate 

 heartily with the extension service and to keep in close touch with 

 the county agricultural agents and with their State leader. Accord- 

 ingly, we have received many telegrams, letters, and telephone 

 messages from county agents, asking for ad\ice or calling for assist- 

 ants to be sent to their counties to aid the farmers. 



THE GRASSHOPPER OUTBREAK OF 1917 



During the fall of I'-'Ki reports reached this office indicating that 

 grasshoppers had been abundant during the summer in the kdathead 

 Indian Reservation in the northern part of Missoula C'ounty. I'otmty 

 agents of the surrounding counties were warned and ste]xs ^\•ere 

 taken to do everything possible during the s])ring to i>re\ent or 

 reduce the damage that might reasonably be expected in \'M1. Assist- 

 ant .State Entomologist H. L. Seamans made a thor<iugh sur\ey of 

 the situation in the early s]iring. 



On the occasion of the hrst trij). in the middle of Aj^ril. eggs 

 had been found in abundance and on this early date dead grasshop- 

 pers ui the pre\ious year could l)e found, as well as evidence of the 

 damage that had l)een done to winter ^\•heat. l\ggs were f(nmd in 

 ditch banks, fence rows, especially around alfalfa and clover fields. 

 With manv of these eggs were found an abundance of ground beetle 

 larvae and adults { //a /-/xi / us sp.). The first grasshopper eggs 

 hatclied. so far as our records sliow, alxmt Ma\" I'lth.
