One means of check-

measure is to keep the 
trunks of the trees clean, 
so that there will be no 
harbour for the pupae 
during winter. A piece 
of any old material may 
be tied round the trunk. 
The pupae will collect in 
this, when the wrapping 
may be removed and the 
insects destroyed. The 
trees may be sprayed over

rate of i oz. to 12 gall, of
