Viral Systemic Movement Is Enhanced by Alteration of a Structural Phloem Protein by the Insect Vector

Advanced Science
The ability to access and exploit the vascular system is essential for viral systemic spread within plant hosts. Insect‐borne viruses can be released from the vector's stylets into plant phloem together with saliva components that facilitate viral ...

The effect of sewage sludge application to an agricultural soil on the fecundity of the Rose Grain aphid (Metopolophium dirhodum).

A pot trial was used to assess the effect of amending soil with sewage sludge on the number of offspring produced by individual Rose Grain Aphids. Results demonstrated that the highest application rate (100 t.d.s.
