west bank) no more than a yery slight occurrence can be traced, but 
the forests are almost unexplored (D. F. 0., Dec. 1919). 
Pegu Circle. 
15. Thayetmyo. 
Present in the East Yoma Reserve [D. F. 0., Sept., 1913] in teak 
forest of the upper mixed type at about 1,500 feet; rainfall possibly 45 
inches. The proportion of beeholed logs from this division recorded 
at the Rangoon depot is 8 per cent. 
16. Prome. 
Recorded from various reserves, but not abundantly. The output 
of beeholed logs is considered to be higher than from Thayetmyo division. 
17. Zigon. 
The beehole borer was noted in plantations in Zigon Division, where 
fortunately the pest is rare. [R. F. A., 1908-09 p. 8., para 41]. In 
1919 the D. F. O. noticed beeholed trees to a greater or less degree in all 
plantations, but considered that none of the natural teak suffers appre¬ 
ciably. 
18. Tharrawaddy. 
Present in all reserves on the west slopes of the Pegu Yoma, Minhla, 
Mokka, Kadinbilin, Konbilin, Thonze, but is not so abundant as in 
some of the Upper Burma forests [D. F. 0., Nov., 1913.] None of the 
working-plans for these reserves mentions the occurrence of the borer. 
Stebbing [1905] notes that “ Bee-holes in teak in the Tharrawaddy 
Division are said to be by no means common ” and records finding 
examples in plantations in Kadinbilin Reserve. 
Present in plantations of the Thonze Reserve [F. R. 0., Jan., 1915]. 
Present in Konbilin Reserve in natural forests and plantations [F. Z., 
1917] (for details of the incidence in plantations near Hmyachaung, 
Konbilin, see pp. 95—97). 
The forests in the above-mentioned reserves on the west slopes of 
the Yomas are of the upper mixed type both moist and dry with a rainfall 
of about 80 inches. 
19. Rangoon. 
With regard to Okkan Reserve it is stated [D. F. 0., Nov., 1913 and 
F. C. Oct., 1913] that the borer is very abundant. “ Only 10 per cent,
