A study of the population dynamics of cereal aphids. Preliminary data on organisms that attack aphids in three different localities



A study of the population dynamics of cereal aphids. Preliminary data on organisms that attack aphids in three different localities



Parasitica 29(3): 134-151



Notes are given on the fungi, Hymenopterous parasites and predators observed attacking aphids during surveys carried out on winter wheat in Belgium in 1971-73. The principal aphids found were Acyrthosiphon (Metopolophium) dirhodum (Wlk.) and Macrosiphum (Sitobion) avenae (F.); the other species were A. (Metopolophium) festucae (Theo.) and Rhopalosiphum padi (L.), which were generally present in very small numbers.
