APPLE PESTS. 61 



in spring, after which the tiny larvcie emigrate to the 

 nearest fruit buds, and at once begin to suck out the sap. 

 In. a short time each infested bud becomes charged with 

 " honey dew " and excreta, the growth of the blossom is 

 arrested, and the latter shrivels and falls off. The flat 

 yellow-and-brown-spotted larvae go through three moults. 

 After the first moult globules with hairs attached form 

 on its body. After the second one the skin becomes green 

 and clothed with white hairs. At the third moult rudi- 

 mentary wings are formed. Finally, the larva pupates in 

 a few hours, and comes forth as a perfect insect. It is 

 the larvae which does the injury. So far as is known the 

 perfect insect is harmless. 



Eemedies. — (1) Spray the trees thoroughly with the 

 Lime-salt Wash (No. 9) in February or early March. (2) 

 Spray again in September with a Kerosene Emulsion 

 (No. 16). 



Apple Tree Mite (Oribata lapidaria). — This has been 

 found to do considerable damage to apple trees by con- 

 gregating at the base of fruit buds and sucking out the 

 sap. As a consequence, the young fruit withers and re- 

 fuses to develop. The mites are exceedingly small. The 

 adults lay their eggs in crevices of the bark, and from 

 these are hatched tiny larv;;©, which go through a succes- 

 sion of three moults before attaining maturity. 



Remedies. — Spray in summer with a Soft Soap and Kero- 

 sene Emulsion (No. 16), or with No. 1 Formula in Feb- 

 ruary. 



Brown-tail Moth (Euproctis chrysorrhaea). — The 

 larvse of this moth dwell in communities under a web, or 

 " tent " on the foliage of trees, and do considerable injui'y 

 to the young leaves. The parent measures an inch and 

 a-quarter to one-and-three-quarters in the spread of its 

 wings. The forewings are white spotted with black; the 

 hind ones pure white. The male has a golden-brown tail. 

 The moths fly during the night only. The female lays her
