11.— LIST OF THE PESTS OF VEGETi^BLES IN BURMA— cowcW. 



In this list of vegetables also I think that some of the names require 

 check. It would, for example, be interesting to confirm the existence of 

 Agrotis ypsilon in Burma. I also feel rather doubtful about Pieris 

 brassiccB as, when I looked over Mr. ShroS's collection at Mandalay in 

 1914, the Maymyo examples labelled as P. hrassicce were all P. canidia. 



12.— NOTES ON MISCELLANEOUS PESTS IN BUEMA. 



By K. D. Shroff, B. A. Entomological Assistant, Burma. 



The Paddy Case-worms {Nymphula). This pest is more prevalent in 

 Lower Burma than in Upper Burma. The following notes on his obser- 

 vations and experiments were submitted by Mr. R. A. Beale, Assistant 

 Botanist, Southern Circle, Burma : — 



" Only tender leaves of young rice plants are attacked. Except in 

 very rare cases (where the pest is present in large numbers) the attack 

 is usually not fatal to the plants. When the plants reach a certain 

 stage of development, their leaves become too tough for the pest which 

 then seeks more tender food either among the crop of neighbouring 

 fields or in the grasses on the bnnds." 



" Keeping the bunds clean should be a fairly effective way of checking 

 the spread of the pest, but it is hardly possible to do so on a large scale. 

 Besides, the moths, which are numerous, may fly from field to field and 

 deposit their eggs on healthy tender plants. The caterpillars in their 

 cases may be carried by irrigation or draiaage water ; so it is advisable, 

 when draining an infested area, to place a net or trap across the opening 

 m the bund through which the water passes. The case-worms collect 

 here in large numbers and may be removed and destroyed. Light traps 

 may be used to catch the moths at night."
