Scientific opinion on modelling practice risk assessment
|
The Panel has interpreted the Terms of Reference as a stepwise analysis of issues relevant to both the development and the evaluation of models to assess ecological effects of pesticides. The regulatory model should be selected or developed to address the relevant specific protection goal. |

Searching for nests of the invasive Asian hornet (Vespa velutina) using radio-telemetry
|
Asian hornets (Vespa velutina) are voracious predators of bees, and are the latest emerging threat to managed and wild pollinator populations in Europe. To prevent establishment or reduce the rate of spread of V. velutina, early detection and destruction of nests is considered the only option. |

Selecting honeybees for worker brood that reduces the reproduction of Varroa destructor
|
We investigated an effect of Apis mellifera worker brood on the reproduction of Varroa destructor as a resistance trait by conducting seven generations of bidirectional selection. Initial tests showed twofold differences in mite fecundity (progeny per foundress mites) between colonies of different origins. |

Sex-specific differences in pathogen susceptibility in honey bees Apis mellifera
|
Sex-related differences in susceptibility to pathogens are a common phenomenon in animals. In the eusocial Hymenoptera the two female castes, workers and queens, are diploid and males are haploid |

Sexual transmission of Nosema in polyandrous honeybees
|
Multiple mating (and insemination) by females with different males, polyandry, is widespread across animals, due to material and/or genetic benefits for females. |

Solar Heating of Honey Bee Colonies
|
We studied the impact of solar heating of bee colonies by placing beehives inside Infrared- Polyethylene (PE) covered enclosures, on: hive temperature, bee population, and spring honey production, during the subtropical winter. |

Specific cues associated with honey bee social defence against Varroa destructor infested brood
|
Social immunity forms an essential part of the defence repertoire of social insects. In response to infestation by the parasitic mite Varroa destructor and its associated viruses, honey bees (Apis mellifera L.) have developed a specific behaviour (varroa-sensitive hygiene, or VSH) that helps protect the colony from this parasite |

Sperm parameters of honeybee drones exposed to imidacloprid
|
The objective of this study was to evaluate the effects of chronical exposure of honeybee drones to environmental (5 ppb) and non-environmental concentration (200 ppb) of imidacloprid (IMD) on sperm concentration, motility, viability, and mitochondrial membrane potential measured in semen obtained from 180 drones originating from 18 colonies. |
