meeting recommended the organisation of one-year courses on ento- 

 mology and the provision of special training for the students of the 

 last two years of the Agricultural High-Schools and Universities, 

 which should include practical work at a local bureau. 



The meeting also discussed the urgent question of the infestation 

 by insects of stored grain, about 10 papers being read on this subject. 



A paper by I. V. Emelianov dealt with the existing entomological 

 organisations, of which there are 220 in the whole world, 74 being in 

 Great Britain and its Colonies, 68 in the United States and 51. in Russia, 

 Germany having only 7, while China, Turkey, Portugal and Brazil 

 have none.

 this point having been arrived at) ; the economic advantages of spraying,

Observations show that the attacks of pear thrips [Taeniothrips 

 inconsequens] can be prevented on apples better than on pears. Italian 

 prunes and plums are also liable to be severely attacked. It has been 

 found that absolute control on apples can be achieved, but the results 

 on pears and prunes are not satisfactory. The following mixture was 

 used extensively : — Whale-oil soap, 5 lb. ; Black Leaf 40, f pint ; 

 water, 85 gals.
