2 REPORT ON INJURIOUS INSECTS FOR 1907. 



Applications for information were dealt with from the Board of 

 Agriculture and Fisheries, the Bureau of Entomology of the U.S. 

 Department of Agriculture ; the Land Agents' Society ; the Midland 

 Re-afforesting Association ; the Warwickshire Agricultural Society ; and 

 the Agricultural and Educational Committees of various County 

 Councils. 



In all two thousand and thirty-five written replies have been 

 sent out. 



As compared with former years, for which details were kept, the 

 figures are as follows : 



1903 ... ... ... 189 inquiries. 



1904 ......... 325 



1905 ...... 479 



i97 ......... 1875 



My hearty thanks are due to Messrs. H. Willoughby Ellis, F.E.S., 

 A. H. Martineau, F.E.S., and Claude Morley, F.E.S., for various services 

 rendered. 



The year 1907, proved, so far as animal pests were concerned, a 

 great improvement upon its predecessor. This is partly accounted 

 for by two facts, viz., the year was a very wet one, and also a 

 considerable amount of careful winter spraying had been done in the 

 winter of 1906-07. 



No particular pest has stood out conspicuously. In Worcestershire 

 the larvae of the Wood Leopard Moth have done much harm to young 

 fruit trees. A new pest to Gooseberries has been discovered, but 

 fortunately, so far as I know, it is confined to one plantation. The 

 Apple Sucker, the Winter Moth, and the Lackey Moth are still all 

 too plentiful in all the Midland Counties. 



Eelvvorms, Wireworms, the May Bug, and the larvae of the 

 Turnip Dart Moth have proved very injurious to root crops. 



The Felted Beech Coccus was found in Staffordshire. As I have 

 pointed out in previous Reports, this pest is slowly but surely spreading 

 throughout the country, and is likely ere long to prove very serious 

 on landed estates where beech trees are in any number. 



The Yellow Wood Wasp has been sent in from numerous 

 correspondents and seems to have been unusually plentiful during 

 1907. 



There is a decided increase of the Woolly Aphis. Some of the 

 worst infestations I have ever seen have been noted during the past 

 year. 



INVESTIGATIONS. 



During the past year the work on Insecticides has been continued, 

 as also the experiments upon the Lime and Sulphur treatment for
