employed to catch the females of the Winter Moth. If 

 this is continued and kept fresh during the egg laying 

 season (which lasts about two or three weeks), the flowers 

 will escape injury, and the weevils must be severely 

 thinned out against next season, both by the catching of 

 the perfect insect, and the prevention of progeny. 

 Another method that might be adopted, is to spread a 

 cloth on the ground beneath infested trees, and tap the 

 branches rather smartly, when the weevils become alarmed 

 and fall to the ground, when they may be collected and 

 destroyed. Collect fallen flower buds and burn them. 

 Everything in the nature of rubbish in gardens and 

 orchards that would offer suitable hiding places for the 

 weevils during winter should be cleared away.

 growth of their apple trees, and it is frequently attributed 

 to and considered to be one of the effects of canker. 



The accompanying illustration (Fig. 48) shows its first 

 appearance on the young current year's growth, and the 

 effect, if unchecked, in two or three years' time.
