This, though, the jungle was originally felled and burnt, yet 

 only the lines of trees, which are 15 feet apirt are kept clean for 

 about 3 feet in width. The " Bluker " in between is allowed to 

 grow up and is felled twice a year. Thus the mengkirai, which is 

 ordinarily the first stage of bluker, was growing up together with 

 the Para. Three methods were adopted in dealing with the pest, 

 (a) spraying with Paris green, {b) Hand picking, (c) felling all the 

 bluker. The first which was quite successful preserved all the 

 trees sprayed. It was only applied to a belt of trees cutting off 

 the affected area from the rest of the plantation and effected this 

 also. 



The second was abandoned after a couple of days, as it seemde 

 to effect no diminution in the numbers. 



The third was tried after the second had failed as it was found 

 that the caterpillars hid themselves as soon as the sun was up. 



The felling of the bluker took away what little shade there was 

 and in 3 days all the caterpillar had disappeared. 



It might be argued that in adopting the latter course Govern- 

 ment no doubt preserved their own trees, but at the same time let 

 loose millions of caterpillar to breed and attack Para trees in some 

 other district. 



The caterpillar, however, appears to be quite a common one. It 

 always attacks " Mengkirai " during drought and I saw about 20 

 acres of bluker stripped by it about 3 miles away from Pondok 

 Tanjong ; whence these caterpillars probably came ; and it is also 

 known in Kuala Kangsar District. 



Unfortunately the specimens which were sent to the Curator of 

 the Museum died and so it has not been possible to identify the 

 insect. In appearance it is black with a yellow band at the head 

 and yellow underneath, slightly hairy, the largest about 2 J to 3 

 inches long. It is a most voracious feeder eating almost anything, 

 even the sulphur on a match. From the above it will be seen that 

 at present Para rubber planters have not much to fear from this 

 pest, but at the same time, the occurrence destroys a rather preva- 

 lent illusion to the effect that there are no pests other than white 

 ants which destroy Para. 



It is also possible that the insect may develop a taste for rub- 

 ber in the future, a possibility which our experience at Pondok 

 Tanjong distinctly points to. 



When they appeared in 1898 a smaller area was affected and 

 the insects did not appear in such numbers and only about 20% 

 of the trees attacked failed to recover.
