sometimes stores its cells with them to serve as deUcious 

 morsels for its baby grubs when they hatch. 



Remedial treatments. 



This bud-moth is a difficult insect to control. In nurseries or 

 young orchards it is often practicable to go over the trees in 

 May, when the " nests " are rendered quite conspicuous by 

 one or two brown, dead leaves, and either pick off and destroy 

 the nests, or crush them on the trees with the fingers so as to kill 

 the inclosed caterpillars or pupae. Skillful and thorough work 

 with a poison spray will also control the bud -moth. Make two 

 applications of arsenate of lead, 4 pounds in 100 gallons of water ; 

 the first when the flower clusters first appear, and the second just 

 before the blossoms open. Many growers add the poison to the 

 lime-sulfur used against the scale and blister-mite, making the 

 application just as the tips of the buds begin to show green, and 

 thus avoid a separate spraying for the bud-moth. Recent ex- 

 periments, however, have shown that this early application of 

 the poison has little effect. If these applications are thoroughly 

 made and followed by the spraying usually given for the codlin- 

 moth just after the blossoms drop, this pest can be effectually 



controlled.

Since about 1895 the light, greenish-yellow caterpillars, 

 a})out \ of an inch long with a black head and thoracic shield, 

 of this satiny, brownish-buff Tineid moth have been more or 

 less injurious in apple orchards in western Missouri and adjoin- 

 ing states. The moths, which measure across expanded wings 

 about I of an inch, emerge from the ground early in April, lay
