454 EXPERIMENT STATION KECOED. 



Twenty- fifth report of the state entomologist, 1909, E. P. Felt {N. Y. 

 State 2Ius. Bui. IJfl, 1910, pp. 178, i)ls. 22).— The author briefly summarizes the 

 worii of the year and deals at length with the more important investigations. 



An experiment with the house fly has been previously noted (E. S. R., 23, p. 

 359). Experiments with the brown-tail moth (E. S. R., 22, p. 461) reported in 

 detail " show in a striking manner the futility of depending upon any method 

 of fumigation with hydrocyanic acid gas for the purpose of destroying active 

 caterpillars, not to mention the more resistant dormant larvfe." Tests made 

 with scalecide diluted 1 part to 20 resulted in the death of all the caterpillars 

 even when the period of immersion was limited to half a minute. A summarized 

 account of the codling moth and details of spraying experiments conducted, a 

 summary of which has been previously noted (E, S. R., 23, p. 658) follow, a 

 bibliography supplementary to that given by Slingerland in 1S98 (B. S. R., 10, 

 p. 460) accompanying the account. 



Notes are given on the life history of the hickory leaf stem borer {Acrohasis 

 feltella), which was abundant upon young hickories at Warner; on the rhodo- 

 dendron lace bug (Leptohyrsa explanata) , which was the source of considerable 

 complaint; and on the various plant lice that were abundant during the year, 

 their natural enemies, remedial measures, etc. The fruit tree pests noted 

 include the fruit tree bark beetle {Eccoptogaster rugiilosus), cankerworms, 

 tarnished plant bug, rose leaf hopper {Typhlocijba rosce), San Jose scale. West 

 Indian peach scale (Aulacaspts pentagons) , oyster-shell scale, and blister mite. 

 The small fruit insects noted include the grape blossom midge {Coiitarinia 

 jolinsoni) and tree crickets ((Ecanthus sp.). Mention is made of several shade 

 tree and forest insect pests, namely, elm leaf beetle {GaleruceUa luteola), 

 bronze birch borer (Agrilus aiixius), sugar maple borer {Plagionotus speciosus), 

 European elm case bearer {ColeopJiora limosipcnnella) , false cottony maple 

 scale (Phenacoccus acericola), elm spauworm, spruce bud moth (Tortrix fumi- 

 ferana), and hickory bark borer {Eccoptogaster quadrispinosus) . Other insects 

 noted are Say's blister beetle {Pompliopaa sayi), the army-worm, luminous 

 larvae {Phengodcs plumosa), and a museum pest {Anthrenus verhasci). 



Lists are given of the principal publications of the entomologist during the 

 year, additions to the collection, and insect types in the New York State Museum. 

 An Additional List of Adirondack Insects, prepared by D. B. Young (pp. 123- 

 125), is appended to the report. 



Notes of the season in Connecticut, W. E. Britton {Jour. Econ. Ent., 3 

 {1910), No. 5, pp. 434-^36). — Among other important insects of the year the 

 author mentions the appearance of the brown-tail moth at Thompson and 

 Putnam, thought to be due to the natural spread of the pest, and an outbreak 

 of Bucculatrix canadensisella on birch. 



Report of entomological work, A. E. Stene {Ann. Rpt. Bd. Agr. R. I., 25 

 {1909), pp. 39-91, pis. 12, fig. 1). — Reports are here presented of nursery inspec- 

 tion, and the San Jose scale, elm-leaf beetle, and tussock, gipsy, and brown-tail 

 moth work of the year. 



Report of the entomologist, C. G. Hewitt {Caimda Expt. Farms Rpts. 

 1910, pp. 223-250, t)ls. 3). — A somewhat detailed account is given of the occur- 

 rence of the insect pests of the year with the remedial measures applicable. 



During this period the white grub was one of the most injurious insects, 

 potatoes being severely attacked in many counties in Ontario, and also in 

 Quebec and Prince Edward Island ; in some cases from 12 to 15 grubs were 

 found in a single hill, the potatoes not being worth digging. Numerous com- 

 plaints of injury to potatoes by wireworms were also received from different 

 provinces from Nova Scotia to British Columbia ; in Ontario they were the
