Report of the economic zoologist on cotton insects, L. Ichks (HoI. Min. 

 A(jr. [liticno.t Ai/rcs]. .1 {liXIH). Ao. .1 pp. ,i7.}-.?20).— The author made a study 

 of the insect pests of cotton in Chaco. particular attention bein,:,' 1,'iven to 

 J'nxlciiid ornithoiHtUi and Ahlhi .ri/liiKi. In combating the lepidopterous 

 jiests of cotton good success was had from the use of Paris green or arsenic 

 in the proportion of 1 part to 50 parts of flour. Paris green as well as white 

 arsenic was also used in a fluid foi'iii. 



The boll weevil. Information concerning its life history and habits, 

 \V. Newell (Crop /'r.s7 Com. I.ii. ('in: '.K pp. „'.''. //(/\. 1.',). — .\ summary is 

 presented of the life history and habits of the boll weevil in its dilfereiit 

 stages and the means by which it is disseminated, its migration, hibernation, 

 and other matters connected with an understanding of its history. 



Report of the executive committee upon the Paris green experiments con- 

 ducted against the boll weevil during 1905, P>. \V. Marston. L. S. Frier- 

 .sox, and \Y. Newell [Crop I'c.'<t Com. I. a. Circ. .S, pp. 31, fifis. '/). — A test 

 was made of I'aris green as a means of controlling the cotton-boll weevil. This 

 remed.v was apidied to cotton kept under large wire-screen cages and under Held 

 couditions. 



The season was unfavorable to the work on account of the late development 

 of cotton and other difficulties met with in appl.ying Paris green at the most 

 effective period. \Vhen I'aris green was applied at the rate of lOJ lbs. per 

 acre in 4 applications nearly all of the boll weevils were destroyed, and the 

 insects were greatly reduced in number by the use of 2§ lbs. of Paris green jier 

 acre. The use of the large quantity of Paris green resulted in considerable 

 injury to the cotton and a diminished yield. 



The general conclusion reached from this series of e.xperiments is that Paris 

 green may lie applied to cotton that is blooming and squaring in such a way 

 as to reduce the number of boll weevils, but the injur.v to cotton is quite serious. 

 It is suggested that during average seasons better results may be obtained 

 since Paris green could be applied earlier. 



The tobacco splitworm, an enemy of tomato, eggplant, and poha in Hawaii, 

 .7. KoTiNSKY [lldirnn. Forcatcr and Afjr., 3 {191)6), Xo. 7. pp. 200, 201). — 

 I'litlioriiiKni opcrciilclhi is reported as causing considerable injury to tomatoes, 

 eggplants, and the cape gooseberry in Hawaii. A number of parasites are 

 known to prey npoii this jiest. The artificial remedies suggested by the author 

 include clean cultivation, the removal of all rubbish from cultivated fields, 

 and careful attention to the fertility of the soil. 



An outbreak of locusts, A. ('. Tonnelier {BoI. MUi. Agr. [Bucno.'i .Aijrcs], 

 .') (I'.uH)). \(). 3. pp. 32S--3.')i;. pus. 33). — The injuries caused by large swarms 

 of locusts are described and notes are given on jiractical remedies for combating 

 them. These include the use of barriers and driving by means of brooms and 

 branches.

 especially on the r(>d-legged locust. A brief account is given of the ai)p(>arance 

 and habits of this iiarasite.
