Effectiveness of infrared sensor camera monitoring for detecting pollinator visits to Cremastra appendiculata var. variabilis in a temperate forest in Central Japan

Plant Species Biology, Volume 41, Issue 2, March 2026.
A 4‐year survey of Cremastra appendiculata var. variabilis pollinators was conducted using a commercially available sensor camera throughout the flowering period. Additionally, sensor cameras and interval photography were used simultaneously to compare the number of videos capturing bumblebees.

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany

Insect Conservation and Diversity, Volume 19, Issue 2, Page 268-279, March 2026.
Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.

Is Nocturnal Pollination Important for Crop Production? Experimental Evidence From Small Fruit Crops

Journal of Applied Entomology, Volume 150, Issue 2, Page 147-157, March 2026.
ABSTRACT Insect‐mediated pollination is essential for crop production but is mainly studied considering diurnal pollinators only. Here, we use pollinator exclusion techniques to prevent either diurnal or nocturnal insect visits in small fruit crops: raspberry (Rubus idaeus), over 1 year, and red currant (Ribes rubrum) and black currant (Ribes nigrum ...

Safety evaluation of the food enzyme trypsin from the genetically modified Fusarium venenatum strain NZYM‐FG

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract The food enzyme trypsin (EC 3.4.21.4) is produced with the genetically modified Fusarium venenatum strain NZYM‐FG by Novozymes A/S. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and its DNA. The food enzyme is intended to be used in the processing

Flight control and landing precision in the nocturnal bee Megalopta is robust to large changes in light intensity

Frontiers in Physiology, 2015
Like its diurnal relatives, Megalopta genalis use visual information to control flight. Unlike their diurnal relatives, however, they do this at extremely low light intensities.

Wild Bumblebee (Bombus) Diversity and Nosema (Microsporidia: Nosematidae) Infection Levels Associated with Lowbush Blueberry (Vaccinium angustifolium) Production and Commercial Bumblebee Pollinators

Psyche: A Journal of Entomology, 2012
The primary objective was to determine if the prevalence of Nosema bombi infection is higher for wild bumblebees (Bombus spp.) caught in lowbush blueberry growing areas with a history of commercial bumblebee use than for bumblebees caught in areas ...

Niche analyses and the potential distribution of four invasive bumblebees worldwide

Ecology and Evolution
The introduction of bees for agricultural production in distinct parts of the world and poor management have led to invasion processes that affect biodiversity, significantly impacting native species. Different Bombus species with invasive potential have

Bombus ruderatus

, 1971
9. B. ruderatus (Fabricius, 1775) In Deutschland allgemein verbreitet und überall häufig. Alfken (1913) fing ihn bei Ahrensch. A. C. W Wagner nennt 1937 57 Fundorte. Diese Angaben mögen die Vermutung zulassen, dass. ruderatus zu jenen Zei­ ten hier heimisch war. 1959—6 und 1968—69 konnte er jedoch nicht mehr nachgewiesen werden.
