Abstract

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 'Variegata' were consistently resistant to both species of lace bugs, whereas P. japonica 'Cavatine' was consistently susceptible to both. Pieris japonica 'Temple Bells' was highly susceptible to S. takeyai, but resistant to S. pyrioides. Nymph emergence was noted only with S. takeyai, on 46 Pieris taxa, whereas S. pyrioides nymphs were not observed on any of the Pieris taxa. Choice assays (with 10 Pieris taxa) and whole plant assays (with five Pieris taxa) using S. takeyai alone also were conducted, confirming the resistance of P. phillyreifolia and susceptibility of P. japonica Temple Bells to lace bug feeding.
