654 EXPERIMENT STATION RECORD. 



injurious to staple crops, and fruit insects. Directions are given for the prepa- 

 ration and application of insecticides witli estimates of the probable costs of the 

 materials. A brief account of the spring grain aphis or green bug, by F. M. 

 Webster, and the New Mexico law on orchard inspection are appended. 



Entomological notes, W. B. Gurney {Agr. Gaz. N. 8. Wales, 19 (1908), No. 6, 

 pp. 503-507, figs. 3). — These notes include an account of beetles attacking furni- 

 ture and woodwork, of pea and bean weevils, and of an aphis causing scab on 

 white-skinned sheep, cattle, and horses. The clover aphis appears to be the 

 cause of the affection here reported. An account is also included of beetles of 

 the species Xylotrupcs gideon attacking cocoanut palm in the Solomon Islands. 



Imported insect pests, H. M. Lefroy (Agr. Jour. India, 3 (1908), No. 3, 

 pp. 231-2JtJi). — With a view to the adoption of measures for preventing the 

 introduction of insec-t pests into India, the author here considers the probable 

 origin of those common to that country. He concludes that the evidence derived 

 from tills examination is reassuring, that with the few prominent exceptions it 

 points to a natural immunity from undesirable introductions, partly because of 

 the natural isolation of India, but largely on account of its climate. It is stated 

 that the only measures at present taken against such introduction is the fumiga- 

 tion of all American cotton-seed at ports of entry to insure the destruction of 

 the boll weevil. 



Report of the entomologist, C. B. Simpson {Transvaal Dept. Agr. Ann. Rpt. 

 J904-5, pp. 332-35.'i). — An account is given of the extensive work carried on 

 against the brown locust (Pacliytylus sulcicolUs), and the purple locust (Acrid- 

 ium purpuriferuin) . Other work is reported under the headings of bee keeping, 

 insects injurious to man, insects injurious to domesticated animals, insects 

 l)oisonous to animals, forest insects, insects injurious to orchards, insects in- 

 jurious to field crops, and insects affecting garden crops. 



Effects of spraying with arsenical solutions for locust destruction, H. 

 Ingle {Transvaal Dept. Agr. Ann. Rpt. 1905-6, pp. 190-192). — In order to deter- 

 mine the danger to cattle, birds, and poultry from eating the grass, or locusts 

 poisoned with arsenate of soda and sugar solution as used by the division of 

 entomology, analyses were made. The results show that it is necessary to pre- 

 vent stock from entering the fields of grass recently sprayed, although the danger 

 of poisoning stock diminishes rapidly after rain has fallen. In regard to the 

 danger to poultry from eating the locusts the author states, "it is evident from 

 the determinations that the amount of arsenic in locusts which have died from 

 arsenical poisoning is not very great, and that unless fowls eat an inordinate 

 number of the insects, the danger of poisoning the poultry is not excessive. At 

 the same time, since fowls are very greedy for locusts, care should be taken to 

 prevent them from gorging themselves with the poisoned insects, or harmful 

 effects may follow." 



The codling moth, C. W. Howard {Transvaal Agr. Jonr., 6 {1908), No. 2-J, 

 pp. 523-526, pi. 1). — A brief description is given of the pest and its introduction 

 from Cape Colony, which is now overrun. At present, with the exception of 

 one locality in which extermination is being attempted, there is practically no 

 codling moth in the Transvaal. Imported apples and pears which bear evidence 

 of its presence to the extent of 1 per cent are destroyed. 



Woolly aphis and tobacco extract, C. P. Lounsbury {Agr. Jour. Cape Good 

 Hope, 33 {1908), No. 2, pp. 188-193, fig. /).— This aphis is stated to be the most 

 troublesome apple-tree pest in Cape Colony. The value of tobacco extract is 

 discussed, and notes are given on other remedies and on the life cycle of the 

 insect. 



The apple sawfly (Hoplocampa (Tenthredo) testudinea) {Bd. Agr. and 

 Fisheries [London], Leaflet 205, pp. 2, fig. i).— This leaflet gives a description 

 of the pest, the nature of its injury, its life history, and methods of treatment.
