Brown Mite 137 



Bark Louse. 



This is a minute insect which is more active in the 

 spring, feeding on the tender shoots. Later in the season 

 it secretes a scale under which it lives. It can be controll- 

 ed with -sprays of kerosene emulsion or lime-sulphur ap- 

 plied while the trees are dormant. 



Bud Moth. 



This is a small insect, the larvae of which destroy the 

 flower buds of apples, pears, plums, etc. It can be con- 

 trolled with arsenical sprays applied when the buds are be- 

 ginning to open and again ten days later. 



Apple Magot or Railroad Worm 



Troublesome in some places where it spoils or destroys 

 apples by tunneling through the apples, causing the fruit 

 to fall. Destruction of the infested fruit, together with 

 keeping the orchard in thoroughly sanitary condition are 

 the best means of eliminating this pest. 



Brown Mite 



In some sections of the West this insect has caused 

 considerable trouble to the foliage of all kinds of fruit 

 trees, causing the trees to take on the appearance of being 

 in neecl of water. The mites feed on the leaves, but de- 

 posit their eggs on the branches and limbs. When very 

 abundant they give a reddish color to the bark, quite no- 

 ticeable in the winter. The eggs are deposited in late sum- 

 mer and do not hatch until after growth has begun in the 

 spring. Weldon of the Colorado Experiment Station re- 

 ports that this insect can be most effectively controlled 

 with sulphur used in water as a spray. Flowers of sulphur, 

 one pound to three gallons of water and enough soap so 

 that the sulphur will mix freely with the water, is perfectly 

 effective as a summer spray. Tobacco preparations will kill 

 the mites, but not the eggs, and are effective only when 

 repeated applications are made. Oil sprays seem to pene-
