insects can endure any amount of frost, but the young aphides quickly 

 perish when the temperature falls below the freezing. 



The predaceous insects that attack this and other plant lice are 

 shown in Figs. 3 to 8 and also Figs. 11 and 12. All of these are our 

 friends and should become familiar to us so that we can protect and 

 assist them in their good work.

CODLING MOTH NOTES. 



Every year the Codling moth or Apple-worm appears to be a little 

 more injurious than it was the previous one ; and unless some decided 

 steps are taken here in the west towards its destruction, our apple crop 

 will be more and more affected year after year by its ravages. True, 

 it has been ascertained by the entomologists and other observers of 

 bugs and such like vermin, that there are a number of friendly insects 

 that destroy the pest in one or the other of its stages of growth. But 

 let us not stop here even if we do know that a dozen or more friends 

 are at work trying to rid the orchard of this destructive insect. Let 

 us lend a hand by doing our " share of destruction." At one time, and 

 that, too, within the past few years, the only remedies known against 

 this pest were hand picking, the use of bandages, lights, etc., together 

 with the gathering and feeding of wind-falls. Now, that we have learned 

 that the arsenites applied in water with a force pump have a very bene- 

 ficial effect in the reduction of the insect, it is within our power to have 

 apples without worms or worm holes. 



If our trees are carefully sprayed after the apples have fairly "set" 

 and before they "droop" on the stems it has been pretty well proven 

 that most every worm will be destroyed before it enters the apple. 

 This is accounted for in this wise ; the eggs are laid in the flowers 

 among the calices or green leaf parts of the blossoms. These eggs are 

 hatched and the young worms feed about for some little time prior to 

 entering the fruit, and in so doing are poisoned when poison is present
