104 ORCHARD CATERPILLARS. 



Where aiiiouiit of ground is limited it is very desirable to trench 

 wherever Onion beds have been much infested, in order to put the 

 chrysalids of the autumn brood down to a depth from which the flies 

 cannot come up in the following spring to infest the new crop.

 encouragement for application of the same methods elsewhere. 



Mr. Wise wrote : — "You will be interested to hear that we have

 caterpillars on our trees. I do not expect that we shall give up 

 grease-banding altogether, but I look forward to doing it, say, once in 

 three years, I should not for a moment recommend people who have 

 only grease-banded their trees for the past two or three years to give
