 of such insects as mosquitoes, fleas, lice, and other vectors of disease. 

 A general idea of the equipment of individual British territories 

 for insect work is provided by the following list: 



The difficulty which individual territories have in providing an 

 adequate staff of technical research officers has been emphasized 

 in earlier chapters. In connection with forestry it was suggested 

 that great advantage would be derived from the attachment of 

 research officers to the Imperial Institute of Forestry ready to 

 undertake short-term research in Africa. A similar scheme in 

 regard to the Imperial Institute of Entomology might w ell receive

LOCUSTS 



One branch of the Imperial Institute of Entomology, developed 

 since the recent overwhelming locust invasions in Africa, is con-
