528 SOME SOUTH INDIAN INSECTS. ETC. 



Distribution. -Mysore, Bellary, Kurnul. Gradually spreading 

 eastwards and southwards. 



Lifehistory. Eggs are laid in masses in the ground in October — 

 December, the young nymphs (.-merging about June — July, after 

 the South-West Monsoon Rains have set in. They feed on any 

 low-growing vegetation and are full-grown about September- 

 October, when they pair and lay eggs. The young arc similar to 

 the adult but smaller and both stages are wingless. 



Foodplants. — Cholam, Tenai, Cumbu, Green Gram, Red Gram, 

 Cow-pea. Most low-growing crops are attacked but cotton seems 

 fairly immune. 



Control. — (i) Catching young hoppers (before they have had 

 time to damage crops) by means of small bag-nets. 



(ii) Killing adult hoppers when coupling and laying eggs. 

 (iii) Deep-ploughing of infested fields in December — January 

 to destroy egg-masses.
