There were the usual complaints of sheep ticks, poultry mites, and other an- 

 noying pests of live stock, but by far the most important problem under this head- 

 ing is the mosquito situation in the northeastern part of the State. 



Centering around Chinook and Malta, mosquitoes present a tremendous economic 

 problem during the summer. They become so abundant that labor can not be 

 secured to work in the hay fields; the milk production of dairy cattle drops to a 

 minimum; and little chickens are even killed by them. If an appropriation is 

 secured from the present legislature, this is one of the problems that, will receive 

 attention.

Judging from the small number of complaints (16) of damage to apples, no 

 outstanding injury was done to this crop during the last two years. Of course 

 there were about the normal number of reports of codling moth, blister mite, vari- 

 ous scale insects, and aphids, as shown in the table. A very satisfactory crop was 

 harvested this season (1926).
