Strategies of Sexual Reproduction in Aphids
Die durchschnittliche Dauer der zweiten Kopulation von Uroleucon cirsii (L.) ist sowohl für Männchen als auch für Weibchen kürzer als die der ersten. Dies legt die Vermutung nahe, dass die männlichen Blattläusen zur Verfügung stehende Menge Sperma limitiert ist. Des weiteren wird Ejakulat von …

Reproduction And Survivorship Of Two Species Of Daphnidae
The reproduction and survivorship of Scapholeberis kingi and Simocephalus serrulatus were studied at 10°, 15°, 20°, and 25°C. Life tables were calculated at all temperatures from survivorship data for each species. Replacement rates of S. kingi and S. serrulatus, respectively, were 0.715 and 2.789 …
