 on survival and movement of the boll weevil. J. Econ. Entomol. 59: 277-279. 



Boll weevils, Anthonomus grandis (Boheman) , collected from woods trash in the 

 fall, were reinstalled in woods trash of different depth? and moisture content. 

 Treatments consisted of woods trash of 1, 3, 5, and 7 inches receiving normal 

 rainfall of 14.6 inches, 3 inches of woods trash receiving no moisture, and 3 

 inches of woods trash receiving 14.6 inches of normal rainfall plus 12.5 Inches 

 additional moisture. Survival was greater in woods trash 3 inches deep with no 

 moisture than in other environments provided. Only 1.2% of the weevils involved 

 in the experiment moved from one environment to another.

 insecticides applied with a low-volume mist sprayer. J. Econ. Entomol. 

 60: 608-610. 



Several insecticides were evaluated with ultra-low-volume (1-16 fl oz/acre), low 

 volume (16 fl oz/acre), and conventional (1 gal/acre) ground spray equipment 

 against the boll weevil, Anthonomus grandis Boheman; the bollworm, Heliothis zea 

 (Boddie) ; the cotton aphid. Aphis gossypli Glover; and the carmine spider mite, 

 Tetranychus telarius (L.). Malathion, methyl trithlon, and carbaryl applied as 

 technical mater Tals, solutions, and suspensions showed promise of controlling 

 cotton pests.

 by sterlizing emerging overwintered females with a TH-5040 sprayable bait. 

 J. Econ. Entomol. 68: 551-554. 



A sprayable invert sugar bait containing Thompson-Hayward TH-6040 (N-(4-chioro- 

 phenyl)-N'-(2, 6-dif luorobenzoyl)urea) was applied in the field (as a coarse 

 spray with maximum droplet size in the 3- to 4-mm-diara range) to sterilize fe- 

 male Anthonomus grandis Boheman. Weevil infestations were determined 3 times
