386 EXPERIMENT STATION RECORD. 



the group Ophionini ( pp. 97-125 |. A considerable number of species of these para- 

 sites are described with bibliographical reference notes on their habits, life history,. 

 and hosts. 



Corythuca marmorata is reported as causing considerable damage to chrysanthe- 

 mums during 1903. The insect is described in its various stages and notes are given 

 on its life history. For controlling the pest clean culture and spraying: with whale 

 oil soap are recommended. During the year the author's attention was called to tin- 

 damage caused by various species of plant lice, plum curculio, codling moth, pear 

 psylla, San Jose scale, and other insects affecting fruits, garden vegetables, and shade 

 trees. The author reports sonic success in the introduction of Chinese lady beetles. 



In the control of San Jose scale a number of insecticides were tested. As a result 

 of these experiments it is concluded that a mechanical mixture of crude petroleum 

 containing 20 per cent of the oil is very effective. In early spring whale-oil soap i- 

 recommended. Kerosene emulsion was also found to be a valuable remedy. In 

 experiments with lime-sulphur wash, during which 25 lbs. of lime and 20 lbs. of 

 sulphur for each 240 gal. of water were used after boiling 15 minutes, the results 

 were not as satisfactory as was hoped for. An investigation was also made of diseased 

 and dying trees as affected by forest insects with especial reference to the relation 

 between forest fires and injurious insects. 



Report of the entomologist, C. French (Jour. ]>rj,t. Agr. Victoria, 2 (1904), 

 No. 9, in). 854-859). — During the year under report a number of experiments were 

 carried out in treating various harmful insects such as San Jose scale, plant lice, etc. 

 Brief notes are given on this work, and also on the inspection of orchards, nurseries, 

 and gardens, the fumigation and treatment of old fruit cases, the inspection of 

 imports and exports of fruit plants and grain, and miscellaneous injurious insects 

 and birds. 



Report of the State entomologist for 1903, S. Lampa (Meddel. K. Landtbr. 

 Styr. [Sweden], 1904, No. 97, j>}>. 64, figs. 5). — During the year under report insect 

 injuries were perhaps more extensive than in ordinary years. This is especially true 

 of Melolontha vulgaris and Cheimaiobia boreata. The latter species was exceedingly 

 injurious to birch trees in various parts of Sweden, and notes are given on the habits, 

 life history, and distribution of the pest. A number of remedies were used with 

 considerable success. These included spraying with Paris green, the use of sticky 

 bands, Raupenleim, etc. Good results were obtained from a combination of these 

 methods. Brief notes are also given on Psylla mail, Diloba cceruleocephala, etc. 



Report of the State entomologist, J. B. Smith (Ann. Rpt. New Jersey State Bd. 

 Agr., 31 (1903), pp. 333-344)- — A copy is presented of the law of New Jersey regard- 

 ing the introduction and spread of injurious insects. The author discusses the 

 application and effects of this law, and gives a short account of the work of the ento- 

 mologist during the year. 



Report of the State entomologist, W. M. Schoyex (Aarsber. Offent. ForanstaU. 

 Landbr. Fremme, 1903, pt. 1, pp. 107-140, figs. 27). — One of the most serious pests 

 investigated during 1903 was Aphelenchus fragarue, which caused great damage to 

 strawberries in various parts of Norway. The attacks of these nematode worms 

 caused abnormal growths in the leaf stalks of strawberries, with destruction of the 

 roots and ultimate death of the plants. Notes are also presented, as in previous 

 reports, on the more important insects observed during the year on cereals, grasses, 

 legumes, potatoes, other garden vegetables, fruits, ornamental shrubs, and forest trees. 



Report of the entomologist for the year ending August 31, 1903, C. S. 

 Banks (Ann. Rpt. Philippine. Comi, 1903, II, pp. 594-020, pis. 46). — A brief account 

 is given of the work of the entomologist during the year, with mention of the prob- 

 lems which present themselves for solution. The major portion of the report is 

 occupied with an account of the insects of cacao already noted (E. S. R., 15, p. 1090).
