Thermal tolerance of the rosy apple aphid Dysaphis plantaginea and its parasitoids: Effect of low temperatures on some fitness activities of Aphidius matricariae

This study aimed at evaluating the critical thermal minimum of the rosy apple aphid Dysaphis plantaginea and of two parasitoid species: Aphidius matricariae and Ephedrus cerasicola. In addition, we evaluated some fitness traits of the parasitoid at four temperatures: 20, 15, 10 and 8°C.

本研究旨在测定苹果瘤蚜（Dysaphis plantaginea）以及两种寄生蜂物种——草蚜茧蜂（Aphidius matricariae）和樱蚜茧蜂（Ephedrus cerasicola）的临界热下限（critical thermal minimum）。此外，本研究还在20、15、10与8℃四个温度条件下，测定了这两种寄生蜂的若干适合度性状（fitness traits）。
