Abstract
The aphid Sitobion avenae (F.), parasitized by Aphelinus abdominalis (Dalman), tends to leave either the feeding sites gathering in particular parts of its host-plant or even the host-plant. This behavior partially explains the phenomenon of reduced parasitism contribution to the overall mortality in several aphid population studies as interpreted by Hughes’ method.
