Whole-plant CO2 exchange measurements on azaleas injured by azalea lace bug (Heteroptea: Tingidae) feeding.
Whole-plant gas exchange was measured continuously for 24 h on rooted cuttings of Girard's 'Pleasant White' azaleas. Azalea treatments were azalea lace bug, Stephanitis pyrioides (Scott), feeding injury levels that averaged 6, 13, or 31% leaf-area injury throughout the plant canopies. Gas exchange parameters, including net photosynthesis, dark respiration, carbon use efficiency, and growth, wer...
متن کاملAzalea growth in response to azalea lace bug (Heteroptera: Tingidae) feeding.
The effects of azalea lace bug, Stephanitis pyrioides (Scott), feeding injury on azalea growth and development were investigated using 'Girard's Rose' azaleas during a 2-yr field study in Georgia Low, medium, and high injury treatments, which corresponded to 6, 8, and 14% maximum canopy area injury, were compared with control azaleas that received no lace bug infestation. Flower number, whole-s...
متن کاملRelative differences in susceptibility of Pieris taxa (Ericaceae) to Stephanitis spp. lace bugs (Hemiptera: Tingidae).
Over 60 Pieris taxa (Ericaceae) were measured for their susceptibility to the Andromeda lace bug, Stephanitis takeyai Drake and Maa, and the azalea lace bug, Stephanitis pyrioides (Scott) (Hemiptera: Tingidae) based on leaf damage, adult survival on leaves, and emergence of nymphs in no-choice petri dish assays. Pieris phillyreifolia (Hook.) DC. and P. japonica (Thunb.) D.Don ex G.Don 'Variega...
متن کاملA Scientifi c Review on the Ecology and Management of the Azalea Lace
The azalea lace bug, Stephanitis pyrioides (Scott) (Tingidae: Hempitera), is a major pest of azaleas (Rhododendron L. spp.). Since its introduction from Asia in the 1940s, the pest has spread considerably within and outside the US. It causes severe economic damage to azaleas and also attacks other ericaceous hosts. The widespread acceptance and cultivation of its preferred host plants, azaleas,...
متن کاملEvaluating grower, landscape manager, and consumer perceptions of azalea lace bug (Heteroptera: Tingidae) feeding injury.
A survey using modified azalea stems was used to establish a "tally threshold value" for assessing azalea lace bug, Stephanitis pyrioides (Scott), feeding injury to azalea shrubs. Consumers and green-industry professionals, represented by ornamental growers, landscape architects, and landscape managers, recognized azalea lace bug injury when injured leaf area exceeded 2%. Purchase and treatment...
