crops. Often several species of grasshoppers attack a crop 

 all at once. The main difference between a cricket (gryllidae) 

 and a grasshopper is, the cricket is furnished with a long 

 ovipositor, while the grasshopper has only a rudimentary 

 ovipositor. A cricket which spoils indigo plants by biting 

 through the roots, is locally called Bherwa in Bihar. It has 

 been identified as Schizodactylus monstruosus. There are 

 other crickets injurious to potato crops, to young juar plants, 

 to tea bushes, to cotton, cabbage and other seedlings. In 

 1893 serious damage to jute and rice crops was reported 

 from Comilla as caused by a criket, which was identified in 

 the Indian Museum as Brachytrypes achatinus. 



1,230. The only suggestion that can be offered regarding 

 remedial measures when crickets and grasshoppers are found 

 very destructive to an ordinary agricultural crop, is "Try 

 Hopperdozers." They are likely to prove efficacious, as they 

 have proved efficacious in similar cases in America. A 

 Hopperdozer is a long and shallow trough mounted on 

 wheels, and containing water and kerosine oil, or a quantity 

 of tar only, and dragged or driven along, an infested field. 

 The grasshoppers jump up and get drowned of themselves'in 

 the kerosine and water, or get entangled and killed in the tar. 

 The least touch of kerosine oil kills insects. To avoid spilling, 

 the trough should have partitions of tin. The trough itself 

 may be made of tin, say, 9 ft. long, i ft. wide, 2 inches 

 deep in front end i ft. behind. This trough may be 

 mounted on a wooden frame having two wheels at the two 

 ends. Two men may drag it along with ropes attached to 

 the two ends of the wooden tra: e. A canvas screen or 

 apron may be added to the hinder part of the trough, which 

 will further help in bringing the grasshoppers into the trough 

 or kill them by contact with the kerosine with which the 

 canvas is saturated.
