INJURIOUS INSECTS OF 1904. 47 



fleshy, whitish larva with a brown head. (See Fig. 25.) Both 

 beetle and larva attack and eat other grain or flour insects which 

 are met with. They are, therefore, not an unmixed evil. 



ACKNOWLEDGMENTS. 



The two successful methods of combating the Mediterranean 

 Flour Moth in mills, freezing and spraying zvith C. S.-^, were told 

 me in detail by practical millers who had resorted to these pro- 

 cesses with happy results. To these parties my thanks are due 

 and cheerfully given. I have not hesitated to use information con- 

 tained in W. G. Johnson's article on "The Mediterranean Flour 

 Moth (Ephestia kiichniclla, Zeller) in Europe and America," pub- 

 lished as an appendix to the 19th report of the State Entomologist 

 of Illinois. From Farmers' Bulletin No. 45, United States Depart- 

 ment of Agriculture, "Some Insects Injurious to Stored Grain," 

 by F. H. Chittenden, statements were obtained bearing upon the 

 habits and life histories of insects other than the Flour Moth found 

 in flour mills and elevators. A number of Chittenden's illustra- 

 tions have also been used. 



The Booth Packing Company of Minneapolis very courteously 

 allowed the use of their cold storage rooms in connection with 

 experiments on the effects of dififerent temperatures on the pest 

 under discussion. 



KEY TO INSECTS AFFECTING RASPBERRIES, BLACK- 

 BERRIES, CURRANTS, GOOSEBERRIES, STRAWBER- 

 RIES, GRAPES, MELONS, SQUASHES AND CUCUM- 

 BERS. 



In our last report, a "Key for Orchardists and Nurserymen" is 

 to be found, dealing with insects affecting the orchard and nursery. 

 It has seemed desirable, in order to meet the many inquiries re- 

 garding pests from raisers of small fruits, to conclude the work 

 begun last year by presenting the following key for the identifi- 

 cation of insects attacking the plants given at the head of the 

 paragraph. It is hoped that this key will be of value to market 

 gardeners and others, and to further this, illustrations have been 

 freely used and remedies given in each case, except where noted. 

 As the method of controlling insect attack varies with varying
