46 DESTRUCTIVE INSECTS OF VICTORIA : 



Prevention and Remedies. 



In dealing with matters of this kind, one cannot but 

 recommend a constant vigilance, particularly if the plants 

 are situated in or near Murray Pine country. Should the 

 upper branches, especially, show traces of turning yellow, 

 the trees should be at once examined ; if carefully looked 

 :at, tiny holes may be seen, and probably the beetles may 

 be emerging, as shown on the plate (Fig. I.). In such a 

 <ease, the holes should be probed with wire dipped in 

 bi-sulphide of carbon, leaving the wire in the holes. This 

 could be done by a boy, and would be effective.
