SPAIN- ONE QUARTER OF THE COLONY IN  GALICIA ARE AFFECTED BY VESPA VELUTINA

The Galician Beekeepers Association estimates that between 20,000 and 25,000 hives in Galicia have been attacked in recent weeks by the Asian hornet, especially in the municipalities of Vivero, Burela and Foz. "There are 109,000 registered hives of bees and one in four is damaged by the Asian hornet, between 20,000 and 25,000" calculated the technical secretary of the organization, Xesús Asorey

PORTUGAL- FOREST LANDSCAPES AND GLOBAL CHANGE

Book written by  João C. Azevedo, Ajith H. Perera and  M. Alice Pinto

 

 

 

 

  • A global analysis of drivers of change in forest landscapes and their ecological consequences
  • Emphasizes the challenges faced by forest researchers and managers who must cope with rapid change
  • Chapter authors provide a wide range of experience and perspectives to this volume

 

 

Climate change, land use change, and many other drivers of landscape modification are occurring at increasing rates globally. They affect ecological patterns and processes in forest landscapes, and modify ecosystem services derived from those ecosystems. All of this presents many new challenges to scientists and managers. Although it is not uncommon to encounter the terms “global change” and “landscape” together in the ecological literature, there has been no adequate global analysis of drivers of change in forest landscapes and their ecological consequences. Providing such an analysis is the goal of this volume: an exploration of the state of knowledge of global changes in forested landscapes, with an emphasis on their causes and effects, and the challenges faced by researchers and land managers who must cope with these changes.

CSECH REPUBLIC- INTERACTION OF A NOVEL ANTIMICROBIAL PEPTIDE ISOLATED FROM THE VENOM OF SOLITARY BEE COLLETES DAVIESANUS WITH PHOSPHOLIPID VESICLES AND ESCHERICHIA COLI CELLS

CSECH REPUBLIC- INTERACTION OF A NOVEL ANTIMICROBIAL PEPTIDE ISOLATED FROM THE VENOM OF SOLITARY BEE COLLETES DAVIESANUS WITH PHOSPHOLIPID VESICLES AND ESCHERICHIA COLI CELLS

Paper prepared by Sabína Čujová, Lucie Bednárová, Jiřina Slaninová, Jakub Straka and Václav Čeřovský

 

 

 

Abstract

The peptide named codesane (COD), consisting of 18 amino acid residues and isolated from the venom of wild bee Colletes daviesanus (Hymenoptera : Colletidae), falls into the category of cationic α-helical amphipathic antimicrobial peptides. In our investigations, synthetic COD exhibited antimicrobial activity against Gram-positive and Gram-negative bacteria and Candida albicans but also noticeable hemolytic activity. COD and its analogs (collectively referred to as CODs) were studied for the mechanism of their action. The interaction of CODs with liposomes led to significant leakage of calcein entrapped in bacterial membrane-mimicking large unilamellar vesicles made preferentially from anionic phospholipids while no calcein leakage was observed from zwitterionic liposomes mimicking membranes of erythrocytes. The preference of CODs for anionic phospholipids was also established by the blue shift in the tryptophan emission spectra maxima when the interactions of tryptophan-containing COD analogs with liposomes were examined. Those results were in agreement with the antimicrobial and hemolytic activities of CODs. Moreover, we found that the studied peptides permeated both the outer and inner cytoplasmic membranes of Escherichia coli. This was determined by measuring changes in the fluorescence of probe N-phenyl-1-naphthylamine and detecting cytoplasmic β-galactosidase released during the interaction of peptides with E. coli cells. Transmission electron microscopy revealed that treatment of E. coli with one of the COD analogs caused leakage of bacterial content mainly from the septal areas of the cells.

Highlights

 

  • The cDNA of bee (Apis cerana) inhibitor cysteine knot (ICK) peptide (AcICK) was cloned.
  • AcICK binds directly to fungi, but not to Gram-negative or Gram-positive bacteria.
  • AcICK exhibits antifungal activity.
  • AcICK is a bee venom component that exhibits insecticidal activity.
  • AcICK acts as an antifungal peptide and insecticidal venom toxin.

 

 

Abstract

Inhibitor cysteine knot (ICK) peptides exhibit ion channel blocking, insecticidal, and antimicrobial activities, but currently, no functional roles for bee-derived ICK peptides have been identified. In this study, a bee (Apis cerana) ICK peptide (AcICK) that acts as an antifungal peptide and as an insecticidal venom toxin was identified. AcICK contains an ICK fold that is expressed in the epidermis, fat body, or venom gland and is present as a 6.6-kDa peptide in bee venom. Recombinant AcICK peptide (expressed in baculovirus-infected insect cells) bound directly to Beauveria bassiana and Fusarium graminearum, but not to Escherichia coli or Bacillus thuringiensis. Consistent with these findings, AcICK showed antifungal activity, indicating that AcICK acts as an antifungal peptide. Furthermore, AcICK expression is induced in the fat body and epidermis after injection with B. bassiana. These results provide insight into the role of AcICK during the innate immune response following fungal infection. Additionally, we show that AcICK has insecticidal activity. Our results demonstrate a functional role for AcICK in bees: AcICK acts as an antifungal peptide in innate immune reactions in the body and as an insecticidal toxin in venom. The finding that the AcICK peptide functions with different mechanisms of action in the body and in venom highlights the two-pronged strategy that is possible with the bee ICK peptide.

POLAND- QUALITY OF HONEYBEE DRONES REARED IN COLONIES WITH LIMITED AND UNLIMITED ACCESS TO POLLEN

POLAND- QUALITY OF HONEYBEE DRONES REARED IN COLONIES WITH LIMITED AND UNLIMITED ACCESS TO POLLEN

Paper prepared by Krystyna Czekońska, Bożena Chuda-Mickiewicz and  Jerzy Samborski

 

 

 

Abstract

Older larvae of honeybee drones are fed with a diet containing pollen. It is not known how pollen deprivation during the larval development of drones might affect their reproductive quality. This study investigated ejaculation ability and semen quality in drones reared in colonies with limited (LP) and unlimited (ULP) access to pollen. Access to pollen was limited by pollen traps. Drone brood rearing was not instantly abandoned in colonies with limited access to pollen. Colonies from the LP group reared drones with smaller mass, which ejaculated in fewer numbers and released smaller amounts of semen. The LP and ULP groups did not differ in semen quality as judged by the concentration, number, and viability of spermatozoa in ejaculate. It was found that access to pollen during larval development directly affects the reproductive quality of drones.

This measurement is taken after the regional government has exhausted administrative remedies and consider this quality figure does not include the enclaves of Castilla y León and the regions of the border Community Cantabria complying with the provisions on the requirements of designation.

CHILE- LAUNCHED A NATIONAL CAMPAIG TO PROTECT THE HONEYBEES

The NGO Plan Bee launched an initiative to help with food. Some of the recommended plants are lavender, rosemary, oregano, mint, chamomile, basil, marigold, roses, pennyroyal, strawberry, lemon and tomato. It is also advised to keep a bowl of fresh water near the plants for the bees to hydrate. Antonio Bogdan, director of the organization invited all Chileans to create an unforgettable spring for bees and for all. "We can create life and food sources for pollinators, thus avoiding long trips to our beloved bees, and with this we create an awareness at country level. Everyone can bring something to life and thereby help ourselves. The time is now, "he said.
