Phycitinae) with suggestions for its control

Zoologist, Forest Research Institute, Dehra Dun, 
Introduction. 
A N enquiry into the life-history and control of the shoot borer of 
Toon was included in the programme of the Forest Zoologist, 
passed by the Board of Forestry at its Triennial Meeting in 1913. The 
subject was investigated during the years 1914-16, but, as it was not 
considered a major project, progress was frequently interrupted in 
favour of more important investigations. The enquiry was finally 
brought to a close in 1916 by the absence of the writer on military duty. 
The publication of this record has been delayed for a season in order 
to include descriptions and an account of the life-histories of the para¬ 
sites of the borer, but it is now* evident that the war has indefinitely 
postponed this part of the investigation. An account of the parasites 
will be published in a subsequent record. 
The insectary work was carried out under the direction of the writer 
by the first Assistant to the Forest Zoologist, Mr. N. C. Chatterjee, 
B.Sc., who was also in charge of the sack-band collections and who 
subsequently collated the data. The writer wishes to express his 
appreciation of the care and discrimination displayed by Mr. Chatterjee 
in carrying out the experiments entrusted to him.
