Report on the Condition of Montana Orchards as Regards Insects. 



By R. A. Cooley, Inspector-at-Large to the Board. 



The following report on the condition of Montana orchards as regards in- 

 jurious insects embodies the writer's personal observations in the state and 

 contains facts contributed by the various inspectors of the board. A 

 list of twenty-one species of injurious fruit insects is reported and while 

 it is more than probable that others of importance are here undetected it is 

 fair to assume that as a rule those causing the most (damage are the ones 

 discovered. On fruit trees, as on all vegetation, insects of no economic 

 significance are always to be found. Numerous species of this class have 

 been brought to my attention in various parts of the state, but no mention 

 of them is made in this report. 



The various insects that occur on our fruit trees as well as on our 

 small fruits, are discussed separately, as follows: 



THE CODLING MOTH — The codling moth has been found in this state 

 in four localities, viz: Missoula, Thompson Falls, Kalispell and Helena. In 

 Missoula it is prevalent in the home orchards of the city and has been 

 found by Mr. Bandmann in orchards a few miles outside the city limits. 

 An orchard of about twenty trees in Thompson Falls has been reported by 

 Mr. Colville as containing the moth. During August, 1900, I received speci- 

 men apples from the orchard owned by Mr. Whiteside in Kalispell, which, 

 on examination, were found to contain larvae of this pest. Mr. Parsons, the 

 inspector in Kalispell, was asked to determine the extent of the infestation 

 and report to me. On visiting the orchard he learned that Mr. Whiteside 

 had removed all the fruit from the infested trees and burned it. Mr. Par- 

 sons was unable to find any more of the pest. Mr. Brandegee has reported 

 the codling moth as very abundant in crab apple trees in the city of Helena. 



We may consider the condition as serious as regards this insect, only 

 in Thompson Falls and Missoula. In Missoula particularly the greatest 

 vigilance is to be urged upon the orchardists. No pains should be spared in 

 fighting the pest. 



It is noticeable that the infested localities above mentioned are all in 

 or near large towns. This may be accounted for by the fact that the chances 

 are very much greater for the moth to gain access to orchards in the imme-
