162 EXPERIMENT STATION RECORD. 



[Report of scientific work in the field of entomolog'y during 1907], G. 



Seidlitz {Arch. Naturgesch., 77/ (1908), II, No. 2, pt. 1, pp. 392).— In this first 

 fascicle, tlie literature on general entomology and Coleoptera is listed and 

 classified. 



Insects and entomologists: Their relations to the community at large, 

 J. B. Smith (Pop. Sci. Mo., 76 (1910), No. 3, pp. 209-226, figs. 11; 11 {1910), No. 

 5, pp. 461-411, figs. 26). — A popular lecture delivered before the Entomological 

 Society of America at Boston December 30, 1909. In the second part the earlier 

 American entomologists are briefly considered, photographs of 26 being repro- 

 duced. 



Destructive insects and their control, O. E. Bremneb {Sacramento: Cal. 

 State Com. Hort., 1910, pp. 39, figs. 2S). — A popular account of the more im- 

 portant insect pests which occur in California, with methods of control. 



Report of injurious insects, P. J. Pakrott {West. N. Y. Hort. Soc. Proc, 

 55 (1910), pp. 114-119, figs. 6).— During 1909, it was determined that gnarly 

 pears — fruit stunted, irregular in shape, pitted, and more or less marked with 

 hard, corky spots — are the result of attacks by the false tarnished bug (Lygus 

 invitus). Seventy-five per cent of the fruit in one orchard examined was dam- 

 aged by this insect and 50 per cent of the crop rendered practically valueless. 

 Heterocordylus malinus, previously noted by Slingerland as a source of injury 

 in 1908 (E. S. R., 22, p. 654) attracted considerable attention in the Onondaga 

 Valley and about Waterloo and Geneva. The cherry ermine moth (Hyponomeuta 

 padella) was discovered in a plantation of foreign cherry seedlings (E. S. R., 

 23, p. 657). 



Report of the entomologist, "W. V. Tower (Porto Rico Sta. Rpt. 1909, pp. 

 24-28). — In reporting upon the control of orange pests, mention is made of the 

 injury by and methods used in combating the purple scale and rust mite. 



The larva of one of the Lachnosterna beetles is causing a great deal of damage 

 to the roots of sugar cane. In pot experiments and fieldwork with the pest, 

 lime has given the best results of any of the I'epellents used, while kainit gave 

 equally good results as a killing agent for the grub in the soil. 



Satisfactory results are reported to have been obtained from the use of hydro- 

 cyanic-acid gas in fumigating for a beetle that is a source of injury to stored 

 tobacco. It is stated that as yet no bee diseases have been found on the island 

 and attention is called to the importance of special precaution in purchasing 

 bees from countries where such diseases occur. 



Studies were made of a small beetle (Xylehorus sp.) which destroys the 

 guava and guama, 2 leguminous trees that are used as shade for coffee, and of 

 the coffee leaf-weevil (Lachnopus sp.). The eggs of the last-mentioned species 

 are laid in clusters upon coffee leaves and the larvae upon hatching out pass to 

 the ground. 



Fifth annual report of the state entomologist and plant pathologist for 

 1909, G. M. Bentley (Ann. Rpt. State Ent. and Plant Path. [Tenn.^, 5 (1909), 

 pp. 40, figs. 5). — This report, which is largely devoted to an account of the 

 nursery inspection work, includes frost charts by J. F. Voorhees, which show the 

 latest killing frosts in the spring and the earliest killing frost in the fall, 

 formulas and directions for the application of several lime-sulphur solutions, 

 etc. The laws and amended rules and regulations relating to nursery inspection 

 and the rules and regulations of the state board of entomology are appended. 



Insect notes (Ayr. News [Barbados], 9 (1910), No. 208, p. 122).— The occur- 

 rence of the flower bud maggot of cotton (E. S. R., 22, p. 360) in Antigua during 

 the cotton season of 1909-10 is briefly noted by H. A. Tempany. Earlier plant- 

 ing appears to have been of the greatest value in preventing the attacks of the 

 maggot.
