Mr. McMillan: Against borers. 



Professor Webster: No; that is- entirely foreign to anything included 

 in our duties. 



Mr. Bradley: I would like to know if you have had any experience 

 with the Hazeltine Moth Catcher, advertised? 



Professor Webster: I have not had anything to do with it at all. It 

 is good for nothing. I have received letters from them and never answered 

 them. They have written me again and again, but I have never replied, 

 A few days ago I received a letter from them asking why I had never 



answered their communications. Mr. had one sent to him 



for trial, and he put it out in the orchard to catch the insects. He brought 

 it in in the morning. He had caught a lot of insects; some injurious in- 

 sects, and a good many beneficial insects; some destructive to some things, 

 but not at all to the orchard; but if there was a codling moth caught with 

 those this summer, it succeeded in getting itself so badly used up that 

 we could not recognize it. 



Professor Troop: I would like to give a moment to this, because this 

 moth catcher has been so extensively advertised over the country the past 

 summer that it deserves some attention. People do not know what it is, 

 they do not know the value of it. I have used this moth catcher. I used 

 it last summer, putting it in the orchard about the time the codling moth 

 makes its appearance, and my experience has been the same as Professor 

 Webster's. I have not succeeded in finding a single codling moth in the 

 pan this summer. We got May beetles, and several other kinds, a good 

 many beneficial, but not a single codling moth. 



Professor Goff: We have had about the same experience in Ohio 

 as you have had in Indiana. We caught a good many insects, but not a 

 codling moth, so far as I am able to state. 



Professor Latta: As to the first and second broods of codling moth, 

 I would like to ask Professor Webster what per cent, of the codling moth 

 has come from the first and what from the second hatching? 



Professor Webster: Do you mean in any particular orchard? 



Professor Latta: Any particular orchard that has been sprayed? 



Professor Webster: It is pretty difficult to state, only in a general 

 way. We have had just this ti-ouble: We spray carefully, and there 

 would be scarcely any apples drop until about this time or later. ^ Now 

 the best we can make out of this is this, that we had destroyed all of 

 those worms before they had got into the apple; we could not make any- 

 thing else out of it. Then in September comes another regular shower,, 

 and ten, twenty, thirty, fifty per cent, or perhaps more, of the apples
