654 EXPERIMKNT STATIOA' RECORD. 



Catskills and extensive injuries were reported from the Adirondacks. Seventy- 

 tive species of gall midges were reared during the year. 



An account is given of the life history and hal)lts, with descrii»tions of the 

 several stages, of the poi)lar sawlly {Tyichiociuiipus viminaliH) which has 

 become rather abundant upon Carolina poplars in the vicinity of Albany, also 

 of the grape blossom midge {Contarinia joJinsoni) which was reared for the 

 first time. An aphid, which has for 2 or 3 years caused more or less injury to 

 gladioli bulbs by weakening them, has been found to represent a new species 

 and is here described as Ap]iis gladioli. The pest is apparently unable to breed 

 at the ordinary temperature of the warehouses, but as spring advances and the 

 houses begin to warm up in March the aphids appear in large numbers. 

 Fumigation with sulphur has been found inefficient in controlling this species. 

 Two si)ecimens of a Central American cockroach (Panchlora hyulina) are 

 reported to have been taken in different sections of Albany. A somewhat 

 extended account is given of the typhoid or housefly, and its biology and 

 relation to disease transmission, to which an annotated bibliography of 80 

 titles is appended. 



Under notes for the year the author considers some of the more important out- 

 breaks. Of fruit tree insects, the occurrence of the gipsy and brown-tail moths 

 in Massachusetts, cankerworms, cigar case bearer, and blister mite (Erioplnjcs 

 pyri) are noted. The grape rootworm (Fidia viticida) is said to have caused 

 less injury than during the previous year. The shade-tree insects reported upon 

 are the elm-leaf miner {Kaliosysphinga iilmi), elm-leaf beetle {Galenicella lute- 

 ola), bagworm, fall webworm, white-marked tussock moth, snow-white linden 

 moth (Ennomos siibsigiiarius), and spruce gall aphid (Chermes abietis). White 

 ants are reported to have caused heavy losses in the storage vaults of a New 

 York City printing company, where they riddled blocks upon which the electro- 

 types were mounted and ran galleries through files of back publications. Men- 

 tion is also made of the occurrence of the corn worm (Heliothis armiger) and 

 of the work conducted in the State against mosquitoes. 



A list of the publications of the entomologist and of additions to the collec- 

 tions from October 16, 1907, to October 15, 190S, are also given. In Appendix 

 A (pp. 71-75), J. G. Needham describes two May flies as Siphlonisca cerodromia, 

 n. g. and n. sp., and Potamanthus iiicqiialis u. sp. Appendix B (pp. 76-1.59) 

 consists of a catalogue of the described Scolytidje of America, north of Mexico, 

 by J. M. Swaine. 



Some new fruit pests and other bug notions, M. V. Slingerland (West. N. Y. 

 Hort. .Sor. I'loc, o', (1909), pp. 89-96, pgs. 3).— Attention is called to the fact 

 that more than one-half of the more destructive insect pests of the United 

 States are of foreign origin and that the increasing international commerce in 

 plants and fruits is yearly adding to the list of injurious insects in this 

 country. 



Mention is made of the occurrence of a plum leaf miner {Nrpticula slinger- 

 Uindclla), which recently appeared in destructive numbers in a large plum and 

 prune orchard near Rochester, X. Y. The insect attacks only plum and prune 

 foliage, pears and apples nearby showing no mines. A red bug {Hetcrocordyliifi 

 malinus) appeared during 1908 and destroyed at least 25 per cent of the 

 Greenings, Pound Sweets, and Ben Davis apples in an orchard near Syracuse, 

 and practically the whole crop of Greenings in an orchai'd near Ithaca was 

 punctured to death by the bugs and dropped soon after the fruit set. Its 

 destructive work is said to have been pi'actically all accomplished in May. 

 Other species briefly considered are an apple seed pest, brown-tail moth, Sau 

 Jose scale, codling moth, and lesser apple worm,
