122 BASPBERRY. [1899 



This begins with the swelhng of the Raspberry buds, or even earlier, 

 and continues till the caterpillars spin up ; the moths from the 

 chrvsalids coming out at the season of the opening of the Easpberry 

 flowers. 



This life-history, as we know it now, and for which in its early 

 part we are mainly indebted to Dr. Chapman, gives us the key for 

 practical operations on the pest, for want of knowledge of which, as 

 will be seen by some of the following observations, both loss of crop 

 and disappointment from unsuccessful attempts at remedial measures, 

 were incurred even in the past season. 



In the past season the report of attack at Loughborough merely 

 referred to the specimens sent accompanying, and which proved to be 

 of the Lanipronia nihiella, as a kind of infestation with which the 

 sender was previously unacquainted, and which was injurious to 

 Raspberry canes by boring into the young shoots, and thus slowly 

 killing them. The date of comuiunication was May 12th. 



In the following observations, sent me rather later in the month 

 than the above, on May 23rd, by Mr. W. T. Fisher, from Clifton Road, 

 Rugby, it will be seen that he especially draws attention to having 

 found many of the scarlet caterpillars of L. nihiella, not only on the 

 Raspberry canes themselves, but also on the "young shoots coming 

 up from the ground." I do not remember that this circumstance has 

 ever been recorded previously, and if on investigation it should prove 

 to be a common habit of the caterpillar to work in the young shoots 

 from the ground, as well as in the young shoots from the canes, it 

 would be a point well worth attention. Mr. Fisher remarked as 

 follows : — 



" Lampronut nibit'lla. — I have found a great quantity of these 

 scarlet pests on my Raspberry canes this spring. Every withered 

 shoot has been most religiously removed and burnt at ouce, but on 

 looking over them myself, I noticed that it is not sufficient to look 

 over the mn^s themselves merely, but the young shoots coming up from 

 the ground also require the keenest scrutiny if the greatest benefit 

 possible is desired from the labour expended. I estimate that from 

 ten to eighteen per cent, of the total destroyed came from this source, 

 so that, if these had been neglected, a relatively large number would 

 have been left to propagate the mischief next year." — (W. T. F.) 



On April 26th information was requested from me by Mr. Robert 

 Scott, of the firm of Messrs. R. and W. Scott, of the Clydesdale 

 Preserve Works, Carluke, Co. Lanark, regarding presence of the same 

 infestation (namely, Lampronia nthielhi, of which specimens were sent) 

 to a serious extent in the Raspberry plantations in the district ; and 

 amongst other points it will be seen that available information was 

 still so much needed that w'hat may be called double loss was being
