In the July number of the Monthly, page 208, is an extract from the Canadian Horticulturist, referring to the codling moth, which says : " I set two traps on the 20th of last August, and caught over one thousand moths in one night. The trap is a glass lantern set in a tin pan of water, an inch or more deep."

It would be interesting to know if the moths caught were Carpocapsa pomonella. In my experience of several seasons' collecting, mostly in large orchards with both light and sugar, I have never seen C. pomonella at either. Nor have I ever seen one about my lamp at an open window, where apples and codling moths abounded in the near vicinity. The only instances in which C. pomonella appeared to be attracted by light, were on the inside of cellar windows, where they tried to make their escape to the open air.

In placing a lamp on one side of a breeding cage, in which a number of C. pomonella were confined, they invariably sought refuge on the opposite side, and often concealed themselves, while other species of moths would approach the light.

Many different forms of the trap (which, according to Downing, was first discovered by Victor Adouin, of France), are recommended by horticultural writers for the destruction of the codling moth, which, if my observations are correct, cannot be captured in this way. The use of these traps may be recommended for the destruction of many other species of moths, and also for the Lach-nostera (white grub beetles.)

The only practical methods of preventing or destroying C. pomonella are by the use of Paris green or paper bands.
