Characteristics of diapause in the bean leaf beetle, Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae)
Environmental Entomology 12 (2), 475-477
Abstract: Adult diapause in the bean leaf beetle, Cerotoma trifurcata (Forster), was quantitatively characterized and monitored in North Carolina. In addition, respiration and feeding rates were lower in diapausing than nondiapausing beetles at two temperatures (25 and 30°C). Moreover, these two rates were relatively insensitive to temperature in diapausing beetles, whereas nondiapausing beetles showed significant increases in both respiration and feeding at the higher temperature. Thus, feeding or respiration sensitivity to temperature would appear to be an excellent quantitative measure of diapause in C. trifurcata.
