Strip to the guts
Zigmunds Orlovskis, John Innes Centre
Sap-feeding hemipteran insects acquire plant pathogens during feeding on infected plants. Their gut, as shown in this image, acts as the principal gateway for entry of the pathogen into the body cavity of the insect. From there, the acquired pathogen can move to the insect salivary glands and be ready to be injected into healthy plants during recurrent insect feeding. Understanding pathogen movement within the insect is key to developing measures to control vector-borne plant diseases and so this is an important research topic for scientists at the John Innes Centre on the Norwich Research Park.
