with flaming torches. I know by experience that this insect is attracted 

 by light. This fact might be utilized to destroy the migrating winged 

 forms, by exposing flares— at night — in the affected areas. 



As previously reported, I have identified the insect as Nilaparvata 

 greeni (Homoptera). It is a common species in the Kandy district, but 

 has not been recorded as a pest there. The species is known only from 

 Ceylon. 



In the event of continuous recurrences of the pest, it may be advis- 

 able to abandon — for a time — the cultivation of 5-months paddy, in favour 

 of those varieties that ripen more rapidly. 



I have requested the Mudliyar to collect further information and to 

 report the exact area involved. A careful estimate of extent of the 

 damage, with a valuation of the crop lost, would be useful.
