described. The remedies already mentioned Cor other root maggots may be applied 

 in controlling this species. 



Injurious bugs and cicadas on cotton, T. K I m.<. \ r/. Mitt. Zool. Mus. Berlin, ■■' 

 [1905), No. /,/>/<■ 23-114, pis. /). A. considerable number of species of these insects 

 are discussed from the standpoint of their distribution, biology, and systematic posi- 

 tion in the order of insects. Particular attention is given to Wbicen dahli, Tectocoris 

 lunula cyanipes, Dysdercus sidse, />. dngulatus, Ik superstUU . D. cardinalis, D. sutu- 

 nil us, p. andrea , etc. The habits and life history of each species are briefly described 

 and detailed notesare given on the distribution of the species. A bibliography of 

 the subject is appended to the article. 



The boll weevil and cotton crop of Texas, E. I >. Sanderson I Austin: Dept. 

 A i/r., 1905, pp. £8, pis. ? ).— The author reviews previous estimates which have been 

 made since L894 of the amounl of damage done by the boll weevil. 



Statistics were collected on the cotton acreage of Texas from 1899 to 1904 and on 

 tlic variations in the acreage and in the yields which may be attributed to the work 

 of the boll weevil. In connection with tins discussion map- are presented showing 

 the distribution of the weevil. It is believed that since its introduction into Texas 

 the boll weevil has destroyed 2,000,000 bales of cotton with an estimated value of 

 one I mi ulrcd million dollars. The weevil is seldom extremely injurious in the south- 

 ern part of Texas if stubble cotton is not allowed to remain over winter. Apparently 

 the weevil does not promise to become very dangerous in the western cotton counties. 



The remedy for the boll weevil, \Y. Newell | Crop Pest Com. La. Cure. 3, pp. 20, 

 figs. 5).— Maps are given showing the gradual advance of the boll weevil into Louisi- 

 ana with reference to the effects of cold rainy winters upon the pest. It is believed, 

 however, that the boll weevil will be able to winter successfully in the cotton regions 

 of Louisiana. The cultural method is considered the only emcienl remedy for con- 

 trolling the boll weevil. This consists in early planting, the use ol varieties which 

 mature quickly, the application of fertilizers, thorough cultivation, and destruction 

 of cotton plants in the fall as well as other material in which the beetle- may 

 hibernate. 



The control of the codling- moth and apple scab, C. L. Maim. .ut and \Y. A. 

 Obton ( U. S. Dept. Agr., Farmers' Bui. 247, pp. SI, figs. 9).— The codling moth and 

 apple scab are considered the chief insect enemy and fungus disease of the apple. 

 They may be controlled by the application of a combined insecticide and fungicide 

 and are, therefore, treated together in this bulletin. 



Notesare given on the habits and life history of the codling moth and upon the 

 biology of the apple-scab fungus. Directions are given for banding tree- to catch 

 codling-moth larva- and for the preparation of Paris green and other arsemcals as 

 well as of Bordeaux mixture. It is recommended that in controlling these two pests 

 the first application be made jusl alter the leaf buds have unfolded, the second jnst 

 after the petals fall, and the third and fourth at intervals of about 1"> days. The 

 first application need not contain Paris green, but the other three should be made 

 with a combination of Paris green and Bordeaux mixture. 



Practical suggestions for codling 1 moth control in the Pajaro Valley, W. 

 11. Volck (California Sta. Cvrc. 14, pp. tl,fig.l). — In the Pajaro Valley considerable 

 difficulty has been experienced in fighting the codling moth on accounl ol the un- 

 usual prevalence of dews, which dissolve away the insecticides sprayed upon the 

 trees. 



Paris green was found to cause considerable injury to the trees, even alter it had 

 previously been washed bo as to remove the soluble arsenic! In order to prevent 

 the action of the dew upon Paris green it was coated with heavy oils and other 

 waterproof materials. These coatings, however, were ultimately destroyed. Lead 

 arsenate was found to possess a high weather-resisting property and is, therefore,
