The Mexican cotton-boll weevil, W. C. Stubbs (Louisiana Stos. Circ. 1, pp. 10, 

 Jigs, o, iiKjp 1). — Tlie boll weevil ret-ently appeared on the experiment station grounds 

 at Audubon Park, New Orleans, and drastic measures were taken for eradicating it. 

 The crop of infested cotton was pulled up, dipped in kerosene, and burned; the soil 

 was then saturated with kerosene and tired, after which it was Hooded for several 

 days. Cotton planters are urged to give close attention to their crop in order to 

 detect the presence of the weevil at once. A brief account is given of the life his- 

 tory, hal)its, and a])pearance of the insect. 



The Colorado potato beetle, G. W. Herrick {Mimfntippl Sta. Bui. 81, pp. 8, Jigs. 

 5). — It is reported that this insect now occurs over all parts of the State, even to the 

 gulf shore. Notes are given on the habits and life history of the beetle. A species 

 of ladybug was observed feeding upon the eggs and larvse of this pest. Arsenate of 

 lead was used in spraying experiments, at the rate of 4 lbs. to 50 gal. of water. One 

 application was quite effective in destroying the insects. Similar results were 

 obtained from the use of Disparene. Brief notes are given on the methods of pre- 

 paring and applying these insecticides. 



The principal insect enemies of the sugar beet, F. II. Chittenden ( U. S. Dept. 

 Agr. Bpf. 74, pp. l'>7-2^1, Jigs. (;'>). — An elaborate account is presented of the most 

 important insect enemies of the sugar beet. These include species of flea-beetles, 

 rootwonns, carrion beetles, blister beetles, cutworms, army worm, webworms, zebra 

 caterpillar, locusts, spinach-leaf miner, tarnished plant bug, leaf hoppers, plant lice, 

 white grubs, wireworms, red spider ( Tetranychus hirnacuiatus) , etc. The various reme- 

 dies which have proved effective and practical in the control of these insects are men- 

 tioned in connection with the discussion of each species. 



Fungi parasitic upon Cleonus punctiventris, J. Danysz and K. Wize {Ann. 

 Inst. Pasteur, 17 {1903), No. 6, pp. 4~ 1-446, figs. 2). — Notes are given on the habits 

 and life history of this enemy of sugar beets, with special reference to the requirements 

 for the successful remedy to control the insect. A number of parasitic fungi are known 

 to attack this pest, and special mention is made of Oospora de.^tructri.r, Sorosporellu uvella, 

 Isaria farinosa, and Sporotriclmm glohulifenun. 



A number of experiments were made in distributing cultures of Oospora in sugar- 

 beet fields infested with Cleonus. While the results were not all that could have been 

 desired, the authors believe that they will be more apparent later and that the method 

 is to l)e recommended on the ground that the soil will gradually become infected with 

 the parasitic fungus and will thus have a tendency to destroy the beetles. 



The root borer of sugar cane, N. B. AVatson ( West Indian Bui., 4 {1903), No. 1, 

 pp. 37-47,. figs. 3). — Notes are given on the appearance, habits, and life history of Dia- 

 prepes abbreriatus. The insect is described in its various stages, and the different stages 

 in its life history are presented in a tabular form. A number of natural enemies are 

 known to attack this pest. The artificial remedies recommended by the author include 

 the })lanting of sweet potatoes near the sugar-cane field as a trap for the beetles, and 

 the direct use of lime as an insecticide. 



The codling moth in Australia, A. Despeissis {Jour. Dept. Agr. West Au.'ttralia, 

 7 (1903), No. 2, pp. 87-98, fig. 1). — Until recently Western Australia has l:)een com- 

 paratively free from the codling moth. This was due to special efforts which were 

 made by the provincial government in preventing its introduction. Notes are given 

 on the distribution of the codling moth in various parts of Australia, the insect is 

 described in its various stages, and a brief account is presented of the extent of dam- 

 age done by the insect. The life history of the codling moth in Australia and the 

 external evidences of infestation are also discussed. 



• In combating this pest the author recommends that all rubbish in orchards, espe- 

 cially windfall apples, should be destroyed, that bandages be applied to the trees and 

 regularly inspected for the detection of the larva?, and that arsenical sprays be applied 

 at the proper seasons. The author recommends the use of Paris green, London
