(Buomitus ceramicus) ” and t-liis is continued in 1915-16 thus :—The 
damage done by the “ Bee-hole borer” Buomitus ceramicus, is especially 
serious as the timber attacked is always depreciated and sometimes 
ruined. Observation Stations for the study of its life history have 
now been established in North Toungoo (Pyonchaung Reserve), South 
Toungoo (Bondaung Reserve), Bhamo (Okkyi) and Pyinmana 
(Yanaungmyin Reserve). Observations have been made and recorded ; 
but further progress is somewhat at a standstill owing to the deputa¬ 
tion of the Forest Entomologist to Mesopotamia. 
Mr. Beeson has been in charge of the investigation since 1914. 
[The investigations carried out by the Forest Research Institute 
have been limited entirely to field-work. A tour was made in April- 
May, 1914 in which the life-history of the borer was worked up and 
a scheme outlined for future field-work involving the establishment 
of permanent sample plots and observation areas. This information 
(Forest Zoologist’s Report No. 708—106-13, dated 15th November, 1914) 
was printed for distribution to divisional officers in Burma, and the 
proposals relative to extended field surveys were approved by the Chief 
Conservator. Three officers Messrs A. R. Villar, Deputy Conservator, 
R. Unwin, Assistant Conservator, and W. C. Rooke, Extra Assistant 
Conservator, were deputed in 1916 to carry out special investigations 
on the ecology of the borer, in Shwegu, Pyinmana and North Toungoo. 
Observation areas were also started by Mr. N. Y. Holberton, Deputy 
Conservator in South Toungoo, and by Mr. A. Rodger, Forest Research 
Officer in Zigon. The information collected by these officers is incor¬ 
porated in the present note. In 1917, owing to the claims of war work 
no further progress was made. 
In May-June 1918, the Forest Zoologist collected statistical data 
on the incidence of the borer, and inspected the observation areas in 
the Pegu Yomas. The Report oil the Bee-hole Borer Investigations 
of 1918 was printed and circulated in the province. The data on the 
incidence of the borer in plantations proved somewhat alarming, in 
view of the policy relating to the production of teak in pure crops, and 
an extension of the investigation was ordered. A further tour in 
April-—June, 1919 was devoted to sample plot analyses in seven 
localities. The year was also productive of much valuable informa¬ 
tion on the distribution and abundance of the borer, contributed by 
timber lessees and divisional officers. 
At the request of the Forest Research Institute, Buitenzorg, Java, 
for information on the bee-hole borer, the Forest Zoologist placed his 
unpublished notes at the disposal of that institute. These were exten¬ 
sively reproduced, with courteous acknowledgments by Mr. H. Beekman,
