EEMEDIES. 



The Plusia larvae are the most deHcate of any larvae that I have 

 ever bred ; out of a hundred or so that I have had in my breeding 

 cages, not more than one in ten ever lived to produce moths. 



In a former part of this article I gave an account of the disas- 

 trous effect that wet food had upon a brood of Celery Worms which 

 I had reared from the eggs. From this it would appear that if the 

 plants which are infested with these worms were sprinkled occasion- 

 ally — say two or three times a day — with cold water, that this of 

 itself would be sufficient to destroy the worms.
