eradication might be accomplished. Economic entomologies are 

 weak in agressive organisation to meet the conditions of the present 

 time. A permanent executive committee should decide upon the 

 problems to be attacked, the method of operation and the organisation 

 of public support and co-operation essential to success. 



In the discussion following the reading of this paper, the suggestion 

 regarding the estabhshment of an executive committee was strongly 

 supported and it was finally resolved that a committee on pohcy 

 should be appointed having as its functions the directing of all policies 

 of the American Association of Economic Entomologists, and its various 

 undertakings, the formulation and fostering of great entomological 

 policies for the profession and the working out of a more perfect 

 co-ordination of scientific effort among entomologists and between 

 entomologists and other professions. 



A correction was made in the statement that the cotton boll-weevil 

 has only one food-plant, a native wild plant found in the mountains 

 from Guatemala to Arizona also serving as a host, while some of the 

 native plants of the South also serve to a limited extent as food- 

 plants. It is possible therefore that this pest might survive in spite 

 of a suspension of cotton growing. 



GossARD (H. A.) & Parks (T. H.). The Ohio Wheat Survey.— JZ. 

 Econ. Entom., Concord, N.H., xii, no. 1, February 1919, pp. 58-66. 



For the last two seasons a State-wide survey of wheat infestation 

 has been made in Ohio, with the object of guiding growers to decide 

 whether wheat growing would be advantageous and when sowing 

 could most profitably be done. Some of the results of this survey 

 have already been noticed [see this Review, Ser. A, vi, p. 455]. The 

 present paper gives a general account of the plan^of these surveys, the 

 cost in each season and the results obtained. In consequence the 

 hopeful outlook of the surveyors regarding the 1919 crop, increased 

 acreage was sown with wheat in the autumn of 1918, in spite of the 

 unusual shortage of labour. As a result of the two surveys, definite 

 knowledge was obtained regarding the distribution of wheat pests, 

 and instructions were issued with regard to minimising the probable 

 damage. The date for wheat sowing and cultural and fertiliser 

 practices were recommended on the basis of the surveyors' reports, 

 and the information was widely disseminated. It is thought possible 

 that a series of annual surveys might result in the solution of many 

 far-reaching problems, some of w^hich are enumerated, and it is 

 questioned how far these points might be elucidated by the survey 

 methods, or what other data are required to obtain the desired solution.

 Flour Substitutes. — Jl. Econ. Entom., Concord, N.H., xii, no. 1, 

 February 1919, pp. 66-70. 



When wheat flour substitutes began to be used with wheat flour, 

 wholesale grocers and bakers very soon began to ask for help in pro- 

 tecting their stocks from insects. An enquiry was then undertaken 

 to devise methods of protection and also to study the ecological 

 relations of insects and the various flours and cereals. The consumers
