Ormerod, who acted as consulting entomologist to the Evesham 

 Fruit Growers' Association, has given a detailed account of the 

 various remedies then tried I 1 )- Since that date, spraying with

LIFE-HISTORY. 



The moths make their appearance about the middle or tow r ards 

 the end of October," and the wingless females commence to creep 

 up the trees to lay their eggs. These are small and cylindrical

little groups between the wood and the bark, on cut shoots and 

 in crevices in the bark, where they are fastened with a sticky 

 secretion. 



Early in the spring (on March 25th the first larvae were 

 received from near Evesham this year) the larvae appear, small 

 greyish or greenish-grey caterpillars with dark heads. Later 

 they change to a yellowish-green with white longitudinal stripes. 

 When full-fed, which they usually become from about the middle 

 to the end of May, they are about three-quarters of an inch 

 in length, and they now let themselves down from the trees by 

 silken threads and pupate in the ground beneath. Most of the 

 moths come up in the autumn, but some remain in the pupal 

 stage until the following spring.
