454 E SOI Til INDIAN INSECTS, 



Foodplants. — Casuarina, Rain-Tree (Pithecolobium samanj, and 

 various soft-wooded trees. 



Status. Has been noted as doing serious damage to Casuarina, 

 especially in dry seasons. 



Control.— The larval galleries and freshly-eaten hark around 

 them are evidence of the presence of the caterpillar which is 

 readily destroyed by syringing into its burrow a mixture of 2 parts 

 chloroform and one part creosote. 



NOTE. The generic name Arbela, being pre-occuped in Rhyn- 

 chota, is not available lor tins genus of Lepidoptera. It seems, 

 however, unnecessary to introduce a new term here.

Distribution. Throughout the Plains of Southern India. 



Lifehistory. The eggs are laid singly on Cotton-bolls, into which 

 the caterpillar bores, feeding on the oily seeds. The young eater- 

 pillar is whitish, but when older it assumes a pink tinge until, when 

 full-grown, it is almost of a salmon-red colour. It is then about [5 

 mm. long, moderately stout, smooth except for a few short scattered 

 bristly hairs, with a brown head and prothoracic shield. Pupa 

 brownish, in a slight eoeoon formed on the stem of the foodplant, 

 111 or on the soil, or in the expanded boll itself. 



Foodplants. Cotton. 



Sttitus. A serious pest of cotton, sometimes doing great damage. 

 1 ially to exotic varieties. 



Control. (1) Picking and destruction of first-attacked bolls. 

 •2) Careful removal from the field Ol all open but damaged 

 bolls. Leaving these on the bushes, as not worth plucking, invites 

 attack of this and other cotton pests.
