TENTH ANNUAL REPORT OF- STATE ENTOMOLOGIST 55 



Codling Moth iCydia pomonella L.). The fight against the 

 codling moth carried on by the horticultural inspectors is showing 

 results, especially in the small orchards adjacent to our larger cities 

 where conditions are now much better than they were several years 

 ago. Nevertheless this insect is gradually widening its range and, 

 judging from its behavior in other states, it is only natural to suppose 

 that it will eventually be found wherever apples are grown. 



Bud Moth {Tmetocera ocellana Schif.). The work of the 

 bud moth was observed in a few orchards, but it was not as abundant 

 as in 1911. 



Green Fruit Worm {Xylinasp.). This increasingly abundant 

 apple pest worked more injury in 1912 than in any previous year. 

 It was especially numerous in the Bitter Root Valley where in 

 some instances ten per cent of the fruit was reduced from "fancy" 

 to "culls" by the disfiguring scars caused by green fruit worm attacks. 



Cherry-Tree Ugly Nest {Archips cerasivorana Fitch). The 

 disfiguring nests of this caterpillar were unusually abundant during 

 the past year upon wild cherry and allied shrubbery. 



The Oblique-Banded Leaf-Roller (Archips rosaceana Harris). 

 This insect was noticed for the first time in Montana in the State 

 Nursery greenhouse at Helena last summer where it worked con- 

 siderable injury by defoliating roses. It occurs throughout the 

 United States, causing sporadic injury in rose houses and occasion- 

 ally attacking fruit trees. 



The Corn Ear Worm {.Heliothis armiger Hub.). As corn- 

 growing increases the corn ear worm will prove increasingly trouble- 

 some. This year it was reported from Huntley and Great Falls. 

 In the south this pest is highly injurious to cotton and in the corn 

 belt it injures both the foliage and the kernels of corn. 



Cabbage Worms (Pieris rapae L. and Plutella maculipennis 

 Curt.). Like cabbage lice these are the subject of many letters 

 every summer. They will be discussed in a circular on cabbage 

 pests which is about to be issued. 



Meal Moth {Pyralis farinalis L.). Flour infested with lepidop- 

 terous larvae has been sent in and reports of a meal moth infesting 

 boxed cereals in stores have been received. It is probable that the 

 above named insect is responsible for some of the trouble. A study
