Among injuries most likely to be confused with those due to Cylas 

 formicarius, F. (sweet potato weevil) are those caused by termites. 

 The chief differences between these injuries are : — (1) Absence of 

 larvae and pupae in the tunnels made by termites, though their 

 presence is apparent when the tuber is weevil-infested ; (2) absence 

 of excreta when the injury is due to termites, but an abundance of 

 this in the tunnels produced by the weevil ; (3) the exit and entrance 

 holes very apparent in the case of termites, though weevil-infested 

 tubers may show little or no outward evidence of their internal condi- 

 tion ; (4) tunnels made by termites have clean-cut outlines in marked 

 contrast with those made by the weevil ; (5) in growing plants, tunnel- 

 ling larvae of the weevil may be found in the stems near the ground.

Cutworms that have done considerable damage to lucerne in Nevada 

 are Euxoa ridingsiana (desert cutworm) and Lycophotia (Peridroma) 

 margaritosa (variegated cutworm). The former has been found feeding 

 on the young shoots in spring, while the latter causes similar damage 

 to the second crop, eating the buds and the green rind from the stems. 



Though the destruction of cutworms by drowning is not easy, it 

 has been effected where the check system of irrigation was used, and 

 also where the land was sloping and it was possible to wash them from 

 the furrows into a ditch by means of a heavy head of water. Cutworms 

 may also be destroyed in immense numbers by pigs, ground squirrels, 

 turkeys, chickens and blackbirds, and they are also attacked by 

 several parasitic and predaceous insects. 



From time to time, grasshoppers have done serious damage to second 

 crops of lucerne, and recently an Aphid, Macrosiphum creeli, has been 

 numerous enough at times to be destructive to this crop.

 are the Ichneumonids that have been known for many years under
