A Member: How about these flat headed apple borers? 



Mr. Flint: That is an insect I meant to mention. There are 

 two species that look alike and work alike. That insect lays its eggs 

 on the trunks of trees during the late spring and early summer. It 

 is flat, grayish, — it looks gray, but it is really a beautiful bronze 

 beetle. It lays its eggs in the trunk. It will lay its eggs in a place 

 where the bark has been injured. 75% of the eggs will be laid on 

 the south or southwest sides of the tree. We have a great deal of 

 trouble with that beetle on shade trees. You would have the same 

 trouble with it on nut trees. Trees that are newly set and exposed to 

 the bright sun; there will be little areas that will be sun scalds and 

 this insect likes those sun scald spots. It will lay its eggs there. This 

 insect does not go into the wood. It bores the first year into the bark 

 and this keeps enlarging as the insect grows and by fall that burrow 

 may be three or four inches long and about two inches square on a 

 small tree. It then goes into the trunk and makes a cell there, changes 

 in tliat cell to the adult beetle and comes out the next year. It takes 

 two years to complete its growth. That insect is common on nut 

 trees, shade trees and forest trees. The best remedy for it is to go 

 over the newly set trees or injured trees, the latter part of August or 

 first of September and wherever you see any little dead areas in the 

 bark, especially if there are little brown castings coming out, you will 

 find there are borers working in the bark. You can usually cut them 

 out that time of the year. You can get them sometimes with carbon 

 disulphide. 



Pres. Weber: What are some of the natural enemies of the 

 beetle? 



Mr. Flint: They have several insect enemies of the same family 

 as the ant, bees and wasps and some bird enemies; the wood peckers. 



Pres. Weber: The Flicker? 



Mr. Flint: Not much; his food is usually ants. 



A ]\Iember: Does the common June beetle do much damage to 

 nut trees ? 



Mr. Flint: I have known them to completely defoliate a tree 

 and of course there would be damage. There is nothing one can do 

 except spray in that case. You can keep track of the years that the 

 June beetles are coming. They come in three year cycles. 1918, 

 1921, 1924-, and they will be here in 1927.
