Ultrastructure of the stylet pathway of Brevicoryne brassicae in host plant tissue, Brassica oleracea
1986
Kimmins, F.M.
Stylets and salivary sheaths of the cabbage aphid, B. brassicae (L.) were studied in leaf tissue of B. oleracea (L.) with Transmission Electron Microscopy. Examples of inter cellular penetration are described by sections of stylets and saliva in air spaces or between adjacent cell walls. Intracellular penetrations are represented by stylets and saliva within damaged cells. High resolution microscopy reveals a third route, where stylets and saliva lie between cell walls and plasmalemmas. This route is called intramural. The results are discussed with particular reference to signals of Electrical Penetration Graphs and at wider level to aphid-host plant selection and phloem location.
