9. Meiktila. 
Presumed to be absent, except from tbe Popa forests [D. F. 0., 
Dec. 1919]. 
10. Ruby Mines. 
The borer occurs in the division but is usually not a serious pest. 
[D. F. 0., 1913 and 1919] Timber in the Nanme Working Circle (in 
an isolated hill-tract forming the Irrawaddy-lower Shweli watershed) is 
badly beeholed, particularly in the drainage of the Pawaing stream 
a tributary of the Nanme creek that flows into the Shweli [D. F. 0., 
Dec. 1913.] The teak-bearing forest is of the very moist mixed type 
with dense bamboo and ever-green under-growth. 
In the Hintha, Ondok and Kyauktaung Reserves “ the borer is not 
reported to be very prevalent ” [Working-Plan for the Hintha Working, 
Circle 1908-09 to 1937-38.] The forests are drier than those previously 
mentioned and situated in less steep and less elevated hills. Mr. W. G. 
Moore, of the Bombay-Burma Trading Corporation, states (1919) “ the 
Hintha Reserve in the Shweli is very dry, is regularly burnt very badly 
in parts, and is more subject to the beehole borer than any other forest 
in the Ruby Mines.” The borer has not been recorded from the Hmaing- 
daing and Tauktakugyi Reserves in the drainage of the Tagaung stream, 
a tributary of the Irrawaddy ; the forests are considerably drier and 
annually burnt (rainfall 45 inches) with teak on flat land along the 
streams. 
In the Working Plan, 1911-12 to 1930-31 for the Wapyudaung 
forests, which lie in a narrow belt on the west slope of the watershed 
between the Irrawaddy and the south-west branch of the Shweli river, 
and are of the dry mixed deciduous type (rainfall 30-45 inches) it is 
stated that “ insects do damage,” but no reference is made to the 
occurrence of the beehole borer. 
A log from the Shweli Forests, 27' by 6J' girth, examined by the 
writer in the Rangoon Mills of the B. B. T. C. showed 421 beeholes 
exposed on the faces of planks and beams [vide, p. 100.] 
11. Mandalay. 
The presence of the borer in the Madaya Range was noticed by the 
D. F. 0., in 1912 and again in 1919, “ in all fire-protected teak planta¬ 
tions. I did not notice any in the natural teak in the unprotected parts.” 
The Madaya valley is elevated and hilly with a rainfall of 60-95 inches ; 
the teak forest is of the moist mixed type.
