The red-headed funjius ( Spliarostilhc coccoitliila ) is snid to be parasitic on 

 the gloomy scale (Af^pidinitis oh-wura) in many sections of Georgia, but in only 

 a few instances has it been found occurring on the San Jose scale. From the 

 experiments here reiiorted. in which attempts were made to transfer it to the 

 San Jose scale, the author concludes that it does not increase fast enough in 

 (ieorgia to be of much value. 



Report of the investigation of the red scale and its injury to oranges in 

 Spain, P. Aymes and L. Trabut (Bui. Agr. Algcric ct Tunisic, 1 't (190S), No. 9. 

 PI). 215-225, figs. 6). — This is the report of a commission appointed to investi- 

 gate the red scale {Chrysompliciliis minor), with a view to perfecting measures 

 for preventing its introduction into Algiers. 



This species is said to be a native of tropical Asia and also found in the 

 Antilles, but only in countries bordering on the Mediterranean has it become a 

 source of serious injury. The pest is said to have first been observed in Europe 

 by Berlese at Florence, Italy, in 1895. Since 1899 it has become the source of 

 great injury in sections of Spain, particularly to the orange, which when badly 

 attacked has ceased to be grown at a profit. At Barcelona the red scale was 

 found on all green plants offered for sale in the markets, particularly upon 

 palms, and it is concluded that this point is the center of its distribution in 

 Spain and to the Balearic Isles. At Valence it was found in nearly all the 

 orange groves, associated with Lepidosaplics {Mytilaspis) gJovcri and L. citri- 

 cola, two species known in Spain as " serpeta." L. gloveri is said to have 

 destroyed the collection of oranges at the Valence Botanical Gardens. 



The passage of regulations requiring the inspection of imported plants and 

 fruits, particularly nondeciduous plants and oranges, is recommended. 



In combating fruit-tree bark beetles, H. F. Wilson {Ohio Sta. Circ. 89, 

 pp. 4~6). — Phlcetrihns liminaris and Scolyttis rugulosiis are said to be the worst 

 of these pests. The author briefly considers the nature and extent of their 

 injury and methods of treatment. A more extended account by the author of 

 P. liminaris has been previously noted (E. S. R., 20, p. 955). 



The olive fly in Calabria, G. del Guercio (Atti R. Accad. Ecoii. Agr. Georg. 

 Firenze, 5. ser., 5 (1908), No. 1, pp. 18-63). — This is an account of Dacus olece, 

 its injury, and methods of combating it in the province of Calabria, Italy. 



[A tea pest], T. Fetch {Trop. Agr. and Mag. Ceylon Agr. Soc, 32 {1909), 

 Xo. 1. p. 82). — An examination of specimens has shown the so-called green 

 bug (Lvcanitim viridc) and not the Lautana bug {Orlhczia insignis) to be the 

 source of injury to tea plants in Ceylon. 



The raspberry byturus (Byturus unicolor), W. H. Goodwin {Ohio Sta. Bui. 

 202, pp. 173-186, figs. 8). — During the last two years this pest has been the 

 source of almost a total loss of the red raspberry crop of a number of Ohio 

 growers. 



The adults feed upon the young leaves and buds of the raspberry. The 

 larvje develop in the head ui)on \^hich the berry is borne causing the affected 

 berries to ripen earlier and tending to make them small and unfit for niiirket. 

 While the injuries ai'e severe, these are usually confined to small and some- 

 what local areas. It is considered probable that the pest has some insect 

 enemies which in most cases hold it in check as it seems to disappear after a 

 few years of severe injury. It has been previously reported as injurious in 

 Canada, Minnesota, Michigan, New York. Massachusetts, and Ohio. 



Experiments have demonstrated the efficiency of an arsenate of lead spray 

 applied k few days before the beetles emerged from their pupal cells. This 

 time varies in different seasons, but is usually about May 10 in northern Ohio. 

 The spray may be applied most readily with a machine of the grape-sprayer 

 type, but with 1 or 2 nozzles so attached that the spray is thrown directly
