Mr. Alvah Peterson: I would like to ask Mr. Fluke if he had any 

 idea why he cannot control this pest by arsenical sprays. He probably 

 knows that in the case of the Oriental peach moth, the young larva 

 when it enters the fruit or the twig, refuses to eat the outer portion. 

 Have you noticed the entrance of these larvae and did they have the 

 same habit ? If they have the same habit, I would say that this accounts 

 for the fact that you cannot control this pest with arsenical sprays. 



Mr. Charles L. Fluke, Jr.: In Wisconsin pea fields, the seed is 

 sown in no particular drilling method. About the time the pods begin 

 to form, the vines mat together, and it is almost impossible to cover the 

 pods entirely with spray. The infestation is not sufficient sometimes 

 to detect whether it comes from the lack of eating spray, or some other 

 cause. I do not believe I can answer your question positively.
