Abstract
Abstract The development, survivorship, longevity, reproduction, and life table parameters of the spirea aphid, Aphis spiraecola Patch, were evaluated at 25°C on seven commonly grown plants (Polyscias crispata (Bull) Merrill cultivar chicken-gizzard aralia, P. scutellaria (Burman) Fosberg, Vibernum suspensum Lindley, grapefruit (Citrus paradisi Macfadyen), rough lemon (C. jambhiri Lushington), pineapple orange [C. sinensis (L.) Osbeck variety pineapple orange], orange jessamine [Murraya paniculata (L.) Jack]) in the laboratory. Spirea aphid failed to survive on orange jessamine. The developmental times for the immature stages ranged from 7.9 d on P. scutellaria to 9.9 d on grapefruit or pineapple orange. The immature survival varied from 92.7% on P. scutellaria to 78.8% on pineapple orange. The average number of nymphs reproduced per female were 42.7, 35.7, 28.7, 22.3, 18.0, and 11.7 on P. crispata, P. scutellaria, V. suspensum, grapefruit, rough lemon, and pineapple orange, respectively. Female adults li...
