PUPATION RECORD 

 To Determine Date to Spray for Codling-Moth in Third Campaign. 



Name of observer 



Address , 



Location of orchard 



Number of bands . 



Put bands around a number of trees and examine them each week. 

 Provide a tight tin box to contain specimens. As soon as you find 

 worms beneath the bands put them in the tin box, noting thereon the 

 date and number of worms found. Keep the box in the cupboard pro- 

 vided for observation of the second campaign. The next week before 

 going around to examine the bands, see if any of the worms in the 

 tin box have transformed into brown pupae; kill them by puncturing 

 with a pin and place in envelope A, the next week in envelope B, etc.
