MISCELLANEOUS REPORTS. 



REPORT OF THE ENTOMOLOGIST. 



The accompanying report on the insects that were more especially 

 Injurious to horticultural and forestry interests in Nebraska during the 

 past year has been prepared by Professor Myron H. Swenk, my assistant. 



In addition to the report I am including as an apendix the greater 

 portion of an important special bulletin on the "House Fly," recently 

 published by the fly-fighting committee of the American Civic Asso- 

 ciation of Washington, D. C. This bulletin will explain itself.

THE PEINCIPAL INSECTS INJURIOUS TO HORTICULTURE 



DURING 1908-09. 



By Myron H. Swenk, Assistant State Entomologist. 



Two years ago the writer presented to the Nebraska State Horti- 

 cuit.iir.'il Society a report on the injurious insects of the biennium 1906-07, 

 viewed from the standpoint of the horticulturist, and this paper was 

 published as Bulletin 19 of the Society and later reprinted in the Annual 

 report cf the Society for 1908, pages 141-158. In the present paper 

 the intG::tion is to deal similarly with the insect pests of fruits, shade 

 trees and ornamentals which have come to the notice of the Entomologist 

 and his assistant during the two years extending from April 1, 1908, 

 to April 1, 1910. On^y the species not considered in detail in the former 

 report will be amplified upon in this one, since the reader can secure 

 Information upon those pests pireviously discussed by simply refering 

 back to the preceding volumes, thus avoiding useless repetition. 



General Summ<iry of lusect Injuries. 



The codling moth (Carpocapsji pomonella), which was quite fully 

 discussed in the last report, continued to be a great pest in the apple 

 orchards during the two seasons here under discussion. In some orch- 

 ards where the crop was an almost complete failure in 1907-08, the 1909 

 crop was said to be somewhat less severely injured than normally, this 

 being possibly due to a partial starving out of the pest in limited areas. 

 On the whole, however, the 1909 crop was about as severely attacked as 

 ever in orchards where scientific spraying was not practiced. Some small 

 unsprayed orchards which came under the observation of the writer 

 contained scarcely a perfectly sound apple in the entire orchard, owing 

 to the attack of the apple worms and scab. 



The plum cruculio (Conotrachelus nenuphar) forms a close second
