]36 MONTANA EXPEEIMENT STATION 



Further attention was given to the little known grain aphis which 

 continues to cause injury in the Judith Basin and an assistant made 

 one trip to the region where it is present and secured some notes. 



Two new insect pests of currant and gooseberries which have 

 been previously mentioned in our reports were further studied and 

 we now possess fairly complete knowledge of the life-histories of 

 both. The insects referred to are the currant fruit weevil and the 

 currant thrips. It has been found that both of these insects are very 

 injurious and it is desirable that m©ans be devised for controlling 

 them. Experiments in spraying for the currant thrips were con- 

 ducted and- a feasible remedy has been indicated. 



Incidentally material additions from all parts of the State have 

 been made to the insect collections. One new cabinet was purchased 

 and immediately filled with systematically arranged insects. All 

 the spare time that can be secured is being devoted to the insect 

 collections, and an abundance of material, the accumulation of years 

 of collecting in Montana, still awaits study. This collection is 

 indispensable in our work for we are constantly called upon to give 

 the names and important facts regarding a wide variety of insects 

 from all parts of the State. Such work as this is of a miscellaneous 

 nature and does not receive much attention in our reports, yet it 

 consumes much time and is quite necessar3^ 



The above lines of work and many others of a miscellaneous 

 nature have been conducted during the year and are in addition 

 to the main lines- of research conducted by the Station entomologist 

 under research funds furnished by the Federal government.
