 is to the interest of every grower to bring about some 

 permanent protection to themselves against inroads of 

 this kind. 



Prevention and Remedies. 



As this scale is fortunately not as yet common in 

 Victoria we should pay great attention, as remarked above, 

 to a systematic inspection of all imported lemons, oranges, 

 limes, and other members of the citrus family, both trees 

 and fruit. As the wrappers may not always be specially 

 prepared, and the fruit finds its way into many places 

 in the colony, it behoves us to be on the alert to meet 

 the danger of spreading this, to us, comparatively new 

 pest broadcast throughout the colony. 



When a tree or its fruit or both are found to be 

 attacked, thin out as much wood as is consistent with the 

 proper development of the plant. Having burnt the 

 prunings set to work with the sprayer, using the resin 

 compound, instructions about which are mentioned in 

 various parts of this number of the book, also in Part I. 

 As the use of the arsenical preparation of Paris green is 

 comparatively new to us here, and as bee-keepers have 

 complained that bees have been poisoned through sipping 

 the nectar from the flowers of trees which have been 

 poisoned by spraying, I thought it might be of interest to 

 persons engaged in that important industry — agriculture 

 — to furnish them with some information sent to me by 

 my friend Mr. J. Fletcher, the clever chief of the Ento- 

 mological Department of Canada, so that we may be able 

 to avail ourselves of the experiences of a gentleman who 

 has done a vast amount of good work in economic ento- 

 mology throughout the British North American posses-

 should such really exist. 



Mr. Fletcher says — " Apiarists claim that fruit-growers 

 have been spraying their trees whilst in blossom, and their 

 bees have been poisoned by gathering the poisoned nectar.
