Herdman (W. A). Final Report to the Council of the Royal Society 

 and the Ministry of Agriculture and Fisheries, on the Work of 

 the Grain Pests (War) Committee.— i?e^^s. Grain Pests (War) 

 Committee, Royal Society, London, no. 10, February 1921, 16 pp 



In this, the final report of the Grain Pests (War) Committee, a 

 brief summary is given of the earlier reports, all of which have been 

 previously noticed, except no. 9, in which a complete list of the grain 

 pests identified during the work of the Committee is given, with 

 information regarding their abundance, economic importance, 

 geographical distribution, and descriptions of new or unrecognised 

 Hymenopterous parasites. Among parasites, the commonest are 

 the Chalcids, Chaetopsila elegans and Lariophagus calandrae, which 

 kill the larvae of Rhizopertha dominica, Calandra oryzae and C. granaria. 

 They cannot, however, exterminate the weevils ; both parasites and 

 pests survive for an indefinite time in infested wheat, the balance being 

 maintained by an Acarid that attacks the parasites. 



The work of the Committee has demonstrated that the whole 

 subject of grain pests is of serious importance to the Empire, and that 

 it is advisable that a permanent organisation should be created to 

 deal, not only with insect pests, but with all living organisms causing 

 destruction to vegetable food-stuffs. The Committee has therefore 

 drawn up and submitted to the Council of the Royal Society a report 

 suggesting the future organisation of grain-pest work in the British 

 Isles. It is recommended that the State should assume general" 

 responsibility for the continuance of the work, and that it should 

 be divided into the sections dealing with intelligence, research and 

 education. A scheme is suggested as indicating a possible nucleus 

 organisation to deal with the work.
