INFESTATION WORK IV WESTERN TEXAH. 



Doctor Marlatt. There arc four points or districts of infestation 

 in west Texas and New Mexico, namely, the important cotton pro- 

 ducing area in the Pecos Valley in western Texas; a similar area much 

 farther north in the same valley in New Mexico in the vicinity of 

 Curlshud; th(> unimportant Greut-Bend district, the growth of cotton 

 in which is conhncti to a few trivial fields at the hases of the hills; 

 and the much more important and recent cotton development in tho 

 Kio Grande N'alley southeast of El Paso in Texas and northwest of 

 it in Now Mexico. 



The invasion of the Pecos district in west Texas was due to cotton 

 smuggled across the horder from Mexico in the Great Dcnd area. 

 The invasion of the Carlsbad district was apparently from seed from 

 the Pecos \'allev in Textus, and the invasion of the Kl Paso region 

 in Texas and New Mexico is traceable directlyto infested cotton seed 

 brought to the immediate horder at Juarez in freight cars and in 

 connection with traflic, and probably chieily by flight t)f insects 

 across the river. These sources of invasion, particularly for the 

 Great Bend district and the El Paso region, will continue as long as 

 the insect is abui'dant in Mexico, and no permanent control can be 

 certainly cflfected until cooperation with Mexico leads to joint action 

 by that country with the I'nited States. The establishment of 

 noncotton zones, therefore, as to the districts along the Kio (irande 

 immediately bordering Mexico is a rather useless proceeding under 

 present conditions. The establishment of noncotton zones and 

 attempted thoroughgoing cleanup areas in the Pecos N'alley in Texas 

 and >few Mexico would be possif)le but the planters of these areas 

 have not been willing to forego the one crop which is their main 

 staple and the State has not been willing to enforce a nonctdton 

 zone as to these areas. As long as the whole project of the eratlica- 

 tion of the pest in eastern Texas was somewhat on trial there was 

 perhaps some justification for this point of view. 



As a result of conferences held in Texas, on which are based the 

 present control operations in eastern Texas in full coooeration with 

 the State and under adequate State law, it was decided that for the
