Soybean {Glycine sot/a) suffers from surface grasshoppers when eiuitc 

 young', from leaf-eating- caterpillars of several kinds as it grows larger. 

 Except in places where the conditions are suitable, the crop is likely to 

 suffer much from these pests. 



Indigo is attacked by a variety of insects, none of which appear to 

 be of very great importance. An aphis ' and a small scale-hke insect,^ 

 which gather in abundance on the shoots, are pests which weaken the 

 plant and, should the latter not be healthy, will seriously damage it. The 

 hJierwa of Behar is a pest of indigo as of other crops grown where these 

 insects thrive (page 227). Caterpillars of many kinds attack indigo as 

 they do most luxuriant crops, and the indigo plant naturally suffers more 

 as it is grown at a time when other vegetation is not available. It is 

 worth noting that the Java-Natal variety of indigo suffers less than the 

 other varieties of indigo generally grown in Behar. Little is known of 

 these caterpillars and none appear to be specific pests of indigo.
