DISCUSSION. 



Mr. J. M. Smith. I would like to ask the professor about an 

 insect that has been destructive in Wisconsin. He spoke about 

 insects destructive to cabbage. I noticed this last season an in- 

 sect the size of a small fly, in the neighborhood of half an inch 

 in length, as large around as a small darning needle, that 

 attacked the cabbage, laying its eggs on the leaves of the plant. 

 They came in countless numbers in the dry weather and 

 destroyed the plants by the thousands. 



Prof. Oestlund. What was the nature of the injury! 



Mr. Smith. They ate into the leaves and destroyed them so 

 the plant would not head at all. 



Prof. Oestlund. With reference to insects injurious to cab- 

 bage, I would say that I studied those two years ago on the ex- 

 perimental farm. I found there nine species that were injurious, 

 four of which were worms, and all of them quite injurious. 



Mr. Smith. The insect referred to when on the plant is 

 green. 



Prof. Oestlund. From the description given it might per- 

 haps be the cabbage Plutella. I have a sam^^le of those here 

 among my collection of insects. 



The meeting then adjourned till 9:30 o'clock, Friday morning.
