Prof. Troop: It will. 



Mr. Swaim: How about the Rose beetle? 



Prof. Troop: I thought you referred to those affecting the apple. 

 This is very difiicult to reach with anything. They are the worst enemy 

 we have. We have been trying all kinds of methods for this, but we 

 haven't found anything very effective as yet. 



Mr. Van Deman: There is nothing that will kill it. 



Mr. Baxter: I have had some experience along this line, and lessened 

 the number quite perceptibly. I used Paris green and sulphate of copper, 

 and lime and sulphur. I thought perhaps they might get it into their 

 beaks. I have found quite a number of them dead under the trees that I 

 treateci. It seems to me thoy are the worst insect enemy we have. 



Prof. Troop: They could be destroyed, but the thing is to destroy 

 the insect without destroying the tree. Some things will kill the foliage 

 as well as the insect. A great many of thesf- insects hibernate. When they 

 go into the ground it is very difficult to do anything with them. Many 

 hibernate in the rubbish and dry grass and leaves. This is one reason 

 why clean cultivation is so good. If they are hibernating in the leaves 

 and the leaves are cleaned up and destroyed they are destroyed in them. 

 They are hard to destroy. 



Mr. Baxter: I thought I killed some of them on account of their 

 being under the trees, but they might have been ready to die. 



Prof. Troop: The probabilities are they were ready to die. 



Mr. Baxter: Have you any cut that shows the Rose beetle? 



Prof. Troop: No, I haven't a cut of that. 



Mr. Baxter: You will remember I sent you some of these insects. 

 They were entirely new to me. 



Prof. Troop: They are of a yellow brown color with long legs and 

 a long snout. 



Mr. Baxter: Why is it that we can not kill them? 



Prof. Troop: I can not answer that. These beetles are very difficult 

 to destroy. 



: About how large is it? 



Prof. Troop: About one-half incli to three-eighths of an inch. It is of 

 a brownish yellow color, with long legs.
