158 First Report on Economic Zoology. 



Report on Termites or White Ants, and methods 

 of checking the ravages of the same, prepared 

 at the request of the Sudan Government. 



Without having specimens of the White Ants or Termites that arc 

 causing havoc in the Sudan not only to wood-work, telegraph poles, etc., 

 hut also to green crops in the vicinity of Khartoum, it is not possible to 

 give a satisfactory account of any methods for combating the pests, 

 investigation to be of any practical use must be made on the spot. 

 Information has been, however, collected from all sources concerning any 

 measures that have been taken in various parts of the world with a view 

 of checking the serious damage these insects do. This information is 

 embodied in this report. The various African Termites are also einime- 

 rated — their various ways of working pointed out and detailed methods of 

 destroying them given. A number of suggestions for preserving articles 

 from their attack and possible new remedies are also given.
