How to do a clinical trial? Recommendations from the aerobiological point of view
World Allergy Organization Journal, 2019 Background: Allergy immunotherapy is still the only treatment of pollen allergy, providing a long-term effect. Clinical trials with pollen allergic patients are in need of validated, high quality pollen data and forecasts in order to grant comparability ...

Abundance of Insects Inhabiting the Male Strobili of Red Pine [PDF]
, 2017 (excerpt) Southwood (1973) concluded that pollen feeding was probably the first step in the development of the phytophagous habit in insects, because pollen, compared with plant foliage, is rich in nutrients and low in sewndary defense substances ...

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]
, 2011 Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

Pollenkitt is associated with the collectability of Malvoideae pollen for corbiculate bees
Journal of Pollination Ecology, 2023 Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble bees and honey bees from exploiting pollen resources.

Multifunctional Bracts in the Dove Tree Davidia involucrata (Nyssaceae:Cornales) [PDF]
, 2008 Although there has been much experimental work on floral traits that are under selection from mutualists and antagonists, selection by abiotic environmental factors on flowers has been largely ignored.
