fruit at this point. In case of very wet weather 

 it is advisable to give a second spraying about 

 two weeks later and again early in July. The

 appears about that time. The first spraying 

 may be of Paris green or other arensic poison, 

 the subsequent ones with poisoned Bordeaux, 



Cottonwood-leaf Beetle — Striped beetle at- 

 tacking poplars and willows and feeding on 

 leaves -and shoots. Apply arsenites. 



Cutworm — Devours flowers and foliage. Use 

 arsenite spray. 



Curculio — This is a small beetle that atfects 

 cherries, apples and plums — notably the last. 

 The adult beetles have a habit of feeding on 

 the fruit and some of them may be poisoned 

 with a Paris green spray applied just after the 

 blossoms fall. It is also possible to gather the 

 small beetles by jarring them down from the 

 tree and catching them on sheets spread on the 

 ground. Especially constructed "Curculio 

 catchers" are sometimes employed for this pur- 

 pose and are made so that they may be moved 

 from tree to tree. The insects are collected 

 from the sheet and destroyed. 



Earthworms — Troublesome only in potted 

 soil. Water with brine water.
