have free access from one cane to another, no isolation of individual 

 canes being possible, as would be the case where canes are spread out 

 fan-shape on wires." 



On May 14th Mr. E. Scott communicated further regarding the 

 date of the first observation of presence : — 



" This moth, until about six years ago, was unknown in the dis- 

 trict around here ; but about that time one or two growers purchased 

 Raspberry canes (rooted) for planting purposes from England, and it 

 would appear that the infestation was introduced from that quarter, 

 the more so as the grower most badly attacked at the beginning was 

 one of the purchasers referred to." — (R. S.) 



On July 6th Mr. Scott noted as follows : — 



" The Raspberry Moth, about which I wrote you previously, has 

 been pretty generally destructive all over the district, but from my 

 own experience and the experience of others, I should say that the 

 damage is not nearly so great as was once feared. The secondary buds 

 that started from the base of the buds destroyed have come away 

 nicely since the rain fell, and, though the fruit will be a little later, it 

 is not likely to show the sad shortage of crop that so many had 

 anticipated." — (R. S.) 



Prevention and Remedies. — One of the most effectual methods of 

 checking recurrence of attack must certainly be that mentioned above, 

 of breaking off the infested buds, or little shoots, and destroying them. 

 On an occasion of a visit of the Evesham Fruit Experimental Com- 

 mittee to the Toddington Fruit Grounds on May 12th, a large basket 

 was shown filled with Raspberry shoots infested by caterpillars of 

 L. ruhielhi, as a sample of several other basketfuls which had been 

 collected in the previous part of the day, and sweeping clearances of 

 this kind cannot fail to make much difference in the amount of recur- 

 rence of the infestation. 



This method of clearing the pest, however (as previously mentioned 

 in my ' Handbook of Orchard and Bush Fruit Insects,' p. 210), requires 

 some care in carrying out, for, as has been shown, the caterpillar by 

 no means necessarily remains in its own bud. To prevent escape, the 

 buds, or embryo shoots, might be cut into pails with a mixture of 

 soft-soap or of any sticky fluid in them which would prevent the cater- 

 pillar crawling away, or a rough lining of canvas to the collecting 

 baskets which would allow of a good sprinkling of paraffin oil (or of 

 anything that the grubs would not cross at the edges), would probably 

 be a good plan. 



In any case the broken -oft" buds and shoots should be burnt or 

 destroyed in some way as soon as possible, or otherwise, in case the 

 caterpillars are so nearly full-grown as for the time of their change to
