Respiratory activity during embryonic development in a diapausing and a selected non-diapausing strain of the gypsy moth, Lymantria dispar L

Correlation between metabolic depression and ecdysteroid peak during embryogenesis of the desert locust, Schistocerca gregaria (Orthoptera: Acrididae)

“…3) are similar to the temporary depressions of O2 consumption found in the eggs of other insect species, i.e. Periplaneta ameri cana (Kubistová, 1955) (Blattaria); Leptinotarsa decemlineata (Fink, 1925), Popillia japónica (Fink, 1925;Ludwig & Wugmeister, 1955) (Coleoptera); Lymantria dispar (Bell, 1989), Bombyx mori (Gharib & De Reggi, 1983), Manduca sexta (Warren et al, 1986) (Lepidoptera), and; Hylemyia cilicrura (Fink, 1925) (Diptera).…”

“…This course of metabolic changes may also be common for diapausing eggs of Lepidoptera, e.g. Bombyx mori (Luciani & Piutti, 1888) and Lymantria dispar (Bell, 1989).…”

Activity of gut alkaline phosphatase, proteases and esterase in relation to diapause of pharate first instar larvae of the gypsy moth,Lymantria dispar

“…ters diapause 15-20 days after oviposition, just after it consumes a small portion of extra-embryonic yolk (Bell, 1996;Lee and Denlinger, 1996). At this time the rate of oxygen consumption is greatly suppressed (Bell, 1989), the alimentary tract reduces the rate of protein synthesis, and a diapause-specific 55 kDa protein begins to be expressed in the gut (Lee and Denlinger, 1996). In this study we find that the activity patterns of several gut enzymes also reflect changes inherent to the diapause program.…”

“…2. At this time the rate of oxygen consumption is greatly suppressed (Bell, 1989), the alimentary tract reduces the rate of protein synthesis, and a diapause-specific 55 kDa protein begins to be expressed in the gut (Lee and Denlinger, 1996). Eggs developed at 25°C for 30 days, were chilled at 5°C for 150 days and then returned to 25°C for postdiapause development.…”
