In laboratory tests, diflubenzuron (N-[[(4-chlorophenyl)amino] carbonyl]-2,6-difluorobenzamide) (AB-29054), EL-494 (N-[[(5-( 4-bromophenyl)-6-methyl-2-pyrazinyl]amino]carbonyl]-2 ,6- dichlorobenzamide), EL-588 (2,6-dichloro-N-[[[5-( 4-chlorophenyl)-2-pyrazinyl]amino]carbonyl-]benzamide), A13-63220 (N- [[(4-bromophenyl)amino]carbonyl]-2,6-difluorobenzamide), and A13-63223 (2,6-difluoro-N-[[(4-(trifluoromethyl)phenyl]amino]carbonyl]benzamide) prevented development of adult pink bollworms, Pectinophora gossypiella (Saunders) when they were fed in larval diet at 1–10 ppm. Contact experiments with adult moths indicated little activity at up to 18 mg/cm2 except for AI3-3220 and AI3-63223 which caused significant mortality after a 1-wk exposure to treated cage surfaces. Diflubenzuron and EL-494 were tested for systemic activity by treating foliage of cotton plants at rates up to 15.2 mg/plant without effect on subsequent development of the pink bollworm. A further test in field cages using the 2 compounds at a rate of 0.11 kg/ha indicated that diflubenzuron was superior to EL-494 for control of the cotton leafperforator, Bucculatrix thurberiella Busck, but neither compound had any activity against the pink bollworm.
