MONTHLY LETTER OF THE EUREAU OF ENTOMOLOGY 



Number 85 May, 1921 



TRUGX CROP INSECT INVESTIGATIONS 



F. H. Chittenden, Entomologist in Charge 



J. E. Graf, in charge of field work in Mexican bean beetle control at 

 Birmingham, Ala., has recently advised the bureau that the Mexican bean beetle 

 has been found in Georgia along the line of the Alabama Great Southern Rail- 

 way between Rising Fawn and the Alabama line. 



Only small suma are at present available for quarantine and control 

 measures by the States of Alabama and Georgia. The quarantined areas now 

 in force will, however, be extended to include the small infestations i n 

 Tennessee and Georgia and every effort will be made to restrict the further 

 dissemination of the beetle from these outlying points of infestation. 

 It is probable that a branch research station will be established in the 

 vicinity of Chattanooga for a comparison of the conditions there with those 

 encountered at Birmingham. 



R. W. Allen has been appointed to assist Neale F. Howard in the Birming- 

 ham research laboratory with regard to the chemistry of new insecticides 

 which it is proposed to apply to the Mexican bean beetle. 



The following have been appointed to act as district inspectors in connec- 

 tion with the enforcement of Quarantine No. 50 against the Mexican bean bee- 

 tle: J, D. Waugh, F. I. Jeffrey, E. G. Small, G. B. Warren, and H. L. Weatherby. 



B. L. Boyden, in charge of field work in sweet-potato weevil investiga- 

 tions, reports that in spite of conditions incident to the unusual season in 

 northern Florida, such as the drought which has materially delayed draw dis- 

 tribution, sweet-potato planting from certified weevil-free draws is now almost 

 completed. Only about 150,000 more draws will ba required. All of the growers 

 on infested properties have signed contracts and the outlook is exceptionally 

 good for a successful season. 



C. H. Batchelder of the Maine Agricultural Experiment Station has been re- 

 appointed to conduct cooperative experiments in the control of insects which 

 transmit the potato mosaic disease and to make observations on other potato 

 insects in the Aroostook County potato region. He will be stationed at 

 Presque Isle, Maine. 



E. S. Roberts has been appointed to assist M. M. High, in charge of the 

 laboratory at Kingsville, Tex., in experimental work on truck-crop insects. 



William D. Mecum has been reappointed to assist J. E. Dudley, Jr., in 

 spraying experiments against truck-crcp insects at Madison, Wis. 



G. Fletcher h^s b9en appointed to assist Chas. E. Smith, Baton Rouge, 

 La., in connection with rearing experiments.
