cations, the S-^^-labeled 8ulfox<de of UC-2H49 I2-methyl-2-(inethylsulf inyl) 

 propionaldebyde O-(methylcarbamoyl) oxinie] was the major toxic component of 

 squares. Af .er stem applications 8.6-24.2% of the radiolabeled compound was 

 recovered in the plant above the point of treatment.

 control with a systemic insecticide and a boll weevil feeding stimulant. 

 J. Econ. Entomol. 59: 149-153. 



The use of a systemic insecticide, American Cyanamid CL-47031 (cyclic 

 ethylene (Diethoxyphosphinyl) dithioimidocarbonate) , with a feeding stimu- 

 lant to control the boll weevil, Anthonomus grandis Boheman, was explored. 

 Laboratory ter.ts indicated that the treatment of leaves with a feeding 

 stimulant formulated with sucrose and agar altered b-^th the feeding be- 

 havior and movement of boll weevils. CL-47031 applied in a granular for- 

 mulation as a soil treatment and in a lanolin paste as a stem treatment 

 to cotton just beginning to fruit gave substantial mortalities of adult 

 boll weevils. When CL-47031 was applied as a stem treatment to fruiting 

 cotton and a boll weevil feeding stimulant, a water extract of squares 

 (3g/10 ml water) , formulated with sucrose and agar was applied as a foliar 

 spray, weevil mortality was more than twice that obtained when the same 

 insecticide was used alone.

 in cotton plants. J. Econ. Entomol. 59: 961-964. 



The systemic activity of Shell SD-9129 (dimethyl phosphate ester with 3- 

 hydroxy-N-mathyl- cis- crotonamide) in cotton plants was studied by bioassay 

 and radioassay. The Insects and a mite used for bioassay were the cotton 

 aphid, Aphis gossypil Glover; the boll weevil, Anthonomus grandis Boheman; 

 and the carmine spider mite, Tetranychus telarius (L.). After application
