ENTOMOLOGY. 891 



The entomological section, ( '. I',. Simpson I Transvaal Agr. Jour., S {1904), No. 9, 

 pp. 146-151, pi. l,fig. 1). — Notes are given on the habits and injurious effects of the 

 cottony-cushion si-ale, locusts, cockchafers, Bagrada hilaria,etc. A brief account is 

 also given of orchard fumigation. 



Injurious insects, F. Corboz {Chron. Agr. Canlon Vaud, 11 {1904), No. IS, pp. 

 393-396). — prief biological and economic notes are given <>n codling moth, cabbage 

 worm, Cheimatobia brumala, etc. 



Methods of combating 1 animals injurious to cultivated plants and domes- 

 ticated animals, Lecaillon {Bui. Mens. Off. Renseignementa Agr., 3 {1904), June, 

 />/>. 1163-677). — Attention is called to the opportunities offered by present agricultural 

 methods for the multiplication of injurious insects and other animals. An account 

 is presented of the method- which have proved most effective in destroying insect 

 pests. The chief insecticides are described and recommendations are made regard- 

 ing their application. 



Insects and pyrethrum powder, K. Andre {Rev. Hort., 76 ( 1904), No. 19, pp. 

 457,458). — Brief notes are given on the value of pyrethrum in combating cabbage 

 worms, plant lice, red spider, mole crickets, ants, etc. 



The cotton bollworm, A. L. Quaintance and F. ('. Bishopp ( U. S. Dept. Agr., 

 Farmers' Bui. 212, pp. 32, figs. 2). — The losses from this pest have been greater in 

 recent years than ever before. This is partly due to the lack of interest on the part 

 of the planters in the application of remedies. It has been found that the bollworm 

 and boll weevil may best he controlled by the same methods of improved farm 

 practice. The bollworm is most injurious in the western portion of the cotton belt. 

 In this region too little attention has been given to the selection of the seed for early 

 fruiting. The principal crops grown there are cotton and corn, which are the pre- 

 ferred food plants of the bollworm. 



The investigations reported in this bulletin are undertaken to determine the possi- 

 bility of securing an earlier crop of cotton by determining the value of arsenical 

 poisons and of corn as a trap crop. The production of an earlier crop of cotton may 

 be brought about by the use of early fruiting varieties, early planting, early and 

 thorough cultivation, and the use of fertilizers. These methods were tested on a 

 number of farms in Texas. As a rule, fertilizers appear to have a beneficial effect in 

 hastening the fruiting of the cotton crop. The use of early varieties, however, is of 

 equal importance and thorough cultivation is also a large factor. 



On account of the preference of the bollworm for corn, it appears that this plant 

 may he used as a trap crop. For this purpose, however, it should not be planted in 

 belts through the cotton field at the usual time in the spring, but so as to be in silk 

 about August 1. From a study of the egg-laying habits of the moth it is believed 

 that the application of arsenicals will be beneficial if made at the time when the eggs 

 of the August generation begin to hatch. 



The Mexican cotton boll weevil, (i. W. Herrkk {Mississippi Sta. Circ. 17, pp. 

 7, figs. 2). — Brief notes on the origin, appearance, life history, and injurious attacks 

 of this species are presented. 



Insects mistaken for the Mexican cotton boll weevil, E. D. Sanderson ( Texas 

 Sta. Bui. 74, pp. 13, pis. 5, figs. 7). — The cotton boll weevil is described for the pur- 

 pose of showing the differences between the appearance of this insect and that of 

 various other insects which have been mistaken for it. Among the latter mention is 

 made of Lixus Sylvius, Trichobaris texana, white-pine weevil, Hylobius pales, snowy- 

 tree cricket, plum curculio, plum gouger, Chalcodermus seneus, Notoxus calcaralus, 

 Drasterias elegans, and a considerable number of other insects which were found on 

 cotton and other cultivated plants. 



The sugar-cane borer, II. Maxwell-Lefroy (Com. I'm-. Agr. [Mexico], Girc. 9, 

 pp. 39, figs. 10). — An account is presented of the habits, life history, distribution, 

 natural enemies, and means of combating Dialnva saccharalis.
