La crisis mundial de polinización no solo es producida por la pérdida de polinizadores, sino también por su homogeneización, ambos procesos causados por el ser humano. En este documento analizamos los impactos ecológicos que justifican la prohibición de

BumbleBEEP: A Sensor System for Bumblebee Colony Monitoring
We present a bumblebee colony monitoring system, BumbleBEEP. The system is fitted with thermometers and a custom weight sensor. These record data up to every 15 min, recording bumblebee brood nest temperature, environmental ambient temperature, and colony growth.

In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

In colonies of Bombus hypnorum reared in captivity all intermediate body sizes between worker and queen are produced, the body size being determined by the amount of food for the larvae. Queens are produced, if the larvae are fed sufficiently. In captivity queens are produced at every time of the colony development, if one worker has to feed only two ...

Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Status and monitoring of the buff-tailed bumblebee Bombus terrestris Linnaeus (Hymenoptera: Apidae) in Southern Finland [PDF]
Bombus terrestris can cause pollination disturbance in native plants and compete with native bumblebees and other pollinators. The accompanying non-native parasites may also threaten native bees. We report new observations of the commercially used Bombus

Niche analyses and the potential distribution of four invasive bumblebees worldwide
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

Using an opto-cardiograph combined with an infrared gas analyzer regular bouts of abdominal contractions were recorded from last instar larva of Bombus terrestris. The rate of CO2 release was about 0.7 ml g-1 h-1.

SUMMARY To investigate whether root‐sourced ethylene‐precursor 1‐aminocyclopropane‐1‐carboxylic acid (ACC) modulates long‐term salinity responses in tomato, a commercial variety (Solanum lycopersicum L. Mill) was grafted onto three rootstocks differing in ACC/ethylene production: an ethylene‐overproducing mutant (epinastic, epi), a root‐specific ACC ...
