AgamOBP1‐Directed Discovery of Repellents to Control the Spread of Mosquito‐Borne Diseases
ChemMedChem, EarlyView.Toward the discovery of novel mosquito repellents, a library of potential binders of AgamOBP1 (secondary amines) generated from two amines and seven aldehydes was designed aiming to enable interactions with critical amino acids at the DEET‐site and to bridge the DEET‐ and Icaridin sIC‐binding pockets. 1H STD NMR spectroscopy in the presence of AgamOBP1

Nature, 1877 ME. FRANCIS DARWIN has made an interesting addition to his important discovery of nectar-bearing glands on the young fronds of Pteris aquilina, supplied from the ever-welcome experience of Mr. Fritz Muller. The latter gentleman finds that in Brazil the Pteris aquilina is protected from the leaf-cutting ants by those attracted to the nectar, and Mr ...

Draft genome of Rosenbergiella nectarea strain 8N4T provides insights into the potential role of this species in its plant host. [PDF]
, 2020 Background:Rosenbergiella nectarea strain 8N4T, the type species of the genus Rosenbergiella, was isolated from Amygdalus communis (almond) floral nectar. Other strains of this species were isolated from the floral nectar of Citrus paradisi (grapefruit),

Combined nutritional stress and a new systemic pesticide (flupyradifurone, Sivanto®) reduce bee survival, food consumption, flight success, and thermoregulation. [PDF]
, 2019 Flupyradifurone (FPF, Sivanto®) is a new butenolide insecticide that, like the neonicotinoids, is a systemic nicotinic acetylcholine receptor (nAChR) agonist.

Ecography, EarlyView.Boreal and tundra plant communities are expected to change in biodiversity due to increasing global change pressures such as climate warming. One long‐term scenario is increasing compositional similarity, i.e. biotic homogenization, which has been relatively little studied in high‐latitude plant communities.

Bumblebees gain fitness through learning [PDF]
, 2007 Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitness remain virtually unknown. Here we evaluate the learning

Nectar traits differ between pollination syndromes in Balsaminaceae
Annals of Botany, 2019 Background and Aims The attractiveness of nectar rewards depends both on the quantity of nectar produced and on its chemical composition. It is known that nectar quantity and chemical composition can differ in plant species depending on the main ...
