Hello Mr. Radchenko,

It seems to be pollen of Geranium-type. Geraniums are valuable sources of nectar and pollen for honey bees.

Please contact Dr Elisabeth Pierson ([email protected]) or Dr Jan Derksen from Nijmegen Radboud University. They are experts in the field of pollen biology:

I am palynologist and is very difficult to identify pollen grains in electronic microscopy, I need photographs in optical microscopy, it is much easier

It is not easy to identify pollen grains from the SEM even for me as I'm used to see them at the light micrscope The pollen seems to be tricolporate with long colpi, doesn't it? I suppose it could be a pollen of Cistus - type. Cistus is very frequent in the mediterranean area and bees use it as pollen source.

Salut

Il ne s’agit pas de Geranium car les sillons sont assez longs et la maille du réticule est très petite. Il peut appartenir au genre Cistus bien que les pores ne sont pas nets. Comme le signale les collègues plus haut, si vous le photographiez au microscope optique il sera plus facile de l’identifier.

I agree, we need photonic light images, mainly to observe colpi and endoapertures, secondly the exine statification and also around the endoapertures.

Perhaps the pollen belong to Spartium or antoher Papilionoideae cloesr to the genus.

I am of the same opinion with Angela Maria please

It is good to adresse you photo in the good Pollenotheque (photographic base of pollen morphologie),

for exemple, in Botanical Institute of Saint Petersbourg, Russia

Cordialement,

MTT

Dear Marpha,

I additionally prepared the photos of this pollen using a high level light microscope (Olympus BX51 with a DIC-contrast) and have determined that this is pollen of Cistus .

With very best wishes,

Vladimir

Dear George,

Yes, on the body of this bee (Dasypoda michezi Radchenko, 2017) there was only this type of pollen and it was on different parts of the bee body.

Kind regards,

Vladimir
