378 EXPERIMENT STATION RECORD. 



Egypt differed from thai known in this country. The author in the course of his 

 paper shows them to be identical, hut calls attention to the fact that the fungus 

 known in the United States as <>:<>niinu auricomum is not the same as that species 

 found in Europe. In discussing treatment the general possihilities of securing 

 immune strains through selection are pointed out and a variety of bananas immune 

 to root knot is described. The banana is not subject to root rot. 



ECONOMIC ZOOLOGY ENTOMOLOGY. 



The international code of zoological nomenclature as applied to medicine, 

 C. W. Stiles {Pub. Health and Mir. Hosp. Sen: U. S., Hyg. Lab. Bid. 24, pp. 50).— The 

 international code is taken up seriatim, and each article is discussed and recommen- 

 dations given. A detailed synonymy is presented for Taenia solium, T. saginata, 

 Dipylidium caninum, THbothriocephalus lotus, and Ed unococcus granulosus. 



Report of the entomologist, J. B. Smith {New Jersey Stas. Rpt. 1904, pp. 557-652, 

 pis. io, figs. 4). — San Jose scale was unusually abundant during the season and caused 

 great damage. Notes are given on the prevalence of Pseudococcus aceris, elm-leaf 

 beetle, cabbage worms, onion maggot, potato beetle, bollworm, strawberry weevil, 

 etc. Insecticide treatment of cottony maple scale is rather unsatisfactory. Summer 

 applications of soap and kerosene and winter washes are partly effective. 



The second brood of codling moth should be combated with bands, but the band- 

 ing method should be combined with spraying, destruction of infested fruit, and all 

 other known precautions. Cranberry insects are also briefly noted. 



A detailed account is given of attempts to introduce the Asiatic ladybird into Xew 

 Jersey and other localities. Only a portion of the beetles survive the winter even in 

 Georgia. The beetle is apparently unable to keep the San Jose scale in check. 

 Notes are presented on Tenodera sinensis as a predaceous insect. 



A test was made of potassium sulphid, sulphite of soda, and Con-Sol for 

 destroying San Jose scale on peach trees. Potassium sulphid and lime proved most 

 effective 1 . This remedy seems not to injure peach foliage when applied in summer 

 and kills the scale insects. Sulphite of soda was of no avail, and Con-Sol was com- 

 paratively ineffective. 



Lime-sulphur wash was almost a complete failure in New Jersey during the winter 

 of 1903-4 as used by fruit growers. A study was made to determine the causes of 

 failure, and various recommendations are made regarding the composition and prepa- 

 ration of the wash. Caustic soda was thoroughly tested as an insecticide and the 

 results were not encouraging. Salimene and Universal insecticide and scale killer 

 also proved to be of little or no value. Crude oil and kerosene continue to give good 

 results. Kill-O-Scale is quite effective but too expensive. Pyrol tree and plant 

 spray neither killed the scale nor injured the foliage. Horticultural Compound 

 proved effective against plant lice but not against San Jose scale. Rose-leaf tobacco 

 extract gave fairly good results as a remedy for grape-leaf hoppers and scale insects. 



Third annual report of the chief inspector {Ohio Dept. Ayr., Div. Nursery and 

 Orchard Inspection Rpt. 1904, pp. 34). — During the year 1904 the inspector carried 

 on the usual work of his office in the control of harmful pests in nurseries and 

 orchards. Nurseries were inspected, fumigation was carried out on a large scale in 

 houses built for that purpose, and orchard inspection was undertaken wherever it 

 appeared to be necessary. During the year serious injuries were suffered from 

 cankerworin, San Jose scale, elm-leaf beetle, grape-blossom bud-gnat, and other 

 insects. A copy is given of the nursery and orchard inspection law of the State. 



The arrowroot worm {Agr. News [Barbados], 4 {1905), No. 76, p. 74).—Calpodes 

 ethlius is said to cause serious damage to arrowroot, cannas, and related plants. The 

 use of Paris green and London purple appears to give the best results. Certain 

 birds, including the common blackbirds of the Barbados, feed upon these pests.
