3, The Bud Moth. 



Brownish caterpillars with black heads, feeding in the opening-' 

 buds of apple, pear, blackberry, raspberry, and other plants in the 

 spring of the year. Sometimes very injurious to apple, destroying 

 the fruit buds, and by eating out the terminal-growing shoots, caus- 

 ing a bushy appearance of the side buds and giving the tree an un- 

 natural appearance. 



Remedv. — Keep the buds coated with an arsenical poison in 

 the spring of the year. 



4, Canker Worms. * 



Not yet found in Montana. Appearing soon after the foliage is 

 expanded in the spring. Rapidly devouring the foliage or turning 

 it brown. Whole orchards may be seen to be of a brown color at 

 a distance, as a result of the attacks of this insect. When an in- 

 fested limb is jarred the slender caterpillars, about three-fourths of 

 an inch long let themselves down by silken threads, 



Remedy, — Spray promptly and thoroughly with an arsenical 

 poison as soon as their presence is first detected. In regions where 

 they are suspected to be present it is well to keep the trees banded 

 with building paper and smeared with an adhersive substance which 

 may be watched in the spring of the year for the purpose of learning 

 whether or not the wingless moths are ascending the trees to lay 

 their eggs. A large proportion of the damage may be averted by 

 the use of such bands. "Bodlime," sold by the Bowker Insecticide 

 Co., Boston and Cincinnati, is a good adhesive substance to use for 

 this purpose. Tar or printer's ink may be used but are less sat- 

 isfactory. 



5, The Codling Moth. 



The larva is Known as the apple worm and infests a number of 

 fruits, but is most injurious to apple and pear. It is probably the 

 most important pest with which the Montana fruit-grower has to 

 deal. 



Remedy.— Spray with Paris green, arsenate of lead or arsenite 

 of lime after the petals have fallen, again two weeks later, again 

 the first week in August. If it is not yet in your orchard, watch for 

 its appearance by searching for wormy fruit among the wind-falls
