It has been observed during the Apis mellifera L. honey analysis that the electric conductivity and fructose percentage of tree-origin honey was high compared to herb- and shrub-origin honey. One possible reason may be that the trees have deep roots and can absorb more nutrients as compared to herbs and shrubs.
Aphids secrete honeydew to extract protein/ amino acids from sap, but in tree roots there should be plenty of nutrients. So on these observations what do you think about root-aphids - do they secrete honeydew or not?
No, Root-aphids doesn't secrete honey-dew. However, terrestrial aphids secretes honey-dew which invites saprophytic fungus to grow on their secretions to form sooty moulds which interfere with photosynthesis of the plant and the growth and finally the yield.
Dear Tukaram Sathe,
Do you have some reference articles/ research papers mentioning that root aphids do not secrete honey dew? or any website reference
Yes, some subterranean aphids are even attracting ants that collect their honeydew:
