1901 - Mally, F. W. Colonizing the boll weevil. Farm & Ranch 20:3-4. Oct. 26. 



Urges close grazing of cotton stalks in fall. When all stalks cannot be grazed 

 down, the author recommends mowing all but a few rows which are left as a trap, 

 those rows to be poisoned frequently or grazed down. Plans are given for a home- 

 made stalk cutter.

 grandis I. C. Cu). Comn. Parasit. Agr. B. 1 (7) :245-26l. Mexico. 



Various experiments in weevil control. The report contains remarks on the 

 necessity for growing a variety of cotton which will shed the infested squares, if 

 the picking up of squares is to be of importance as a method of control. Experi- 

 ments with gases are reported.

Remarks on the collection of adult weevils from the plants, with description 

 of an apparatus which was used with success in several experiments. The re- 

 sults of several experiments with the picking up of fallen infested squares. The 

 habit of retaining infested fruit was noted on certain varieties and mentioned as a 

 difficulty in destroying the weevil by picking up fallen squares. The deleterious 

 effect of heat upon the weevil is mentioned, and observations upon the effect of 

 sunlight on fallen infested squares. Recommends the use of varieties with sparse 

 foliage and the wide spacing of plants; also laying of rows so as to admit the sun 

 as much as possible.

 Believes the burning of cotton stalks late in winter useless. Remarks on soil 

 preparation and mentions various insects mistaken for the boll weevil.

 fall. Tex. Sta. C. 4, 4 p. 



The remedies for this insect, as mentioned by the author, consist in growing 

 early maturing cotton and in destroying the beetles by grazing the cotton with 

 cattle and pulling and burning the stalks which are unused. It is also recom- 

 mended that the land be plowed deeply late in fall or early in winter.

The boll weevil recently appeared on the experiment station grounds at 

 Aududon 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 fired, after which it was flooded 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 history, habits, and appearance of the insect. Infected squares can be recog- 

 nized readily by what is called "flaring," an opening out and spreading down from 

 the bud of the involucre or shuck.

The article reports the destruction of all varieties of cotton grown on the 

 Louisiana Station during the summer of 1903. Some miscreant placed the Mexican 

 boll weevil in one field and, to successfully exterminate it when found in August, 

 it was deemed necessary to destroy every stalk of cotton on the Station. The 

 cotton was pulled up by the roots, immersed in petroleum and burned; fallen 

 bolls and squares were carefully picked up, saturated with petroleum, and also
