 several rows of eggs laid within the cover of a Leaf-sheath ; the 

 egg is rounded, pale yellow-green. The larva on hatching bores 

 into the stem and is a borer all its life ; its length when full grown 

 is 20 25 mm., its shape cylindrical, rather slender, its general 

 colour usually greyish white, tinged more or less with red or pink, 

 head red-brown. It pupates in the stem itself, the pupa being 

 about 15 mm. long, moderately stout, brownish-yellow. The moth 

 .liter about 10 days. 



Foodplants. Maize, cholam, ragi, paddy, wheat, sugarcane. 



Status. A bad pest of ragi in Madras. 



Control.— The plants attacked usually reveal the presence of 

 the borer by development of "deadhearts " and destruction of these 

 is indicated to prevent extension of the attack.
