Damage to individual cotton plants 'Deltapine 16', by uniform and continuous infestations of 1 late-stage nymph or adult male Lygus hesperus Knight per cage during 4 infestation periods was studied at Tucson, Arizona, in 1969. Nymph-infested plants grew taller and showed altered patterns of squaring, flowering, and bolling, as compared with noninfested controls, but no significant reductions in seed cotton yield or lint quality were detected. Nymph-infested plants yielded lower percentage weights of lint and higher percentage weights of seed. Plants infested with nymphs from the time of 1st square until Aug. 16 had significantly increased numbers of main stem vegetative branches. Plants infested with adults from the time of 1st square until 1st bloom showed altered patterns of squaring and flowering but no significant yield reductions. Lint quality and monetary value were lower on plants exposed to adults during the late infestation period from July 26 to Aug. 16.
