Abstract
Greenhouse and laboratory studies were conducted to determine if chlordimeform affected percent egg hatch of Lygus lineolaris (Palisot de Beauvois). Pole bean (Phaseolus vulgaris L.) pods and cotton (Gossypium hirsutum L.) plants in which L. lineolaris adults had deposited eggs were treated with chlordimeform; nymphs were counted 7 days after adults were removed. When pole bean pods were sprayed with or immersed in a 0.09% solution of chlordimeform, nymphal emergence was not significantly reduced. When cotton was sprayed with chlordimeform, emergence of nymphs was significantly reduced in two of three tests.
