The Sugar-cane Beetle {Ligyrus rugiceps 

 Lee.) 



The stubble and stalks of sugar cane, 

 and the stalks of corn, are burrowed 

 into below the ground by a chunky, black 

 beetle, about half an inch long, with 

 stout, coarsely spined legs. Corn is 

 usually killed, while cane may partly re- 

 cover and make some growth, though 

 the yield will be short. The injury takes 

 place for the most part early in the 

 growing sea- 

 son. 



Eggs are 

 laid in the 

 ground on the 

 weakened or 

 decaying 

 Fig. 96. — The Sugar-cane roots. The 



Carrots planted 

 late escape serious 

 injury. Direct 

 measures of con- 

 trol are the same 

 as for the onion 

 maggot. Freshly 

 manured fields 

 should be avoided.
