Are the causes of bee losses now well- classified?
According to the European Food and Safety Authority (EFSA) no single cause of disapprove bee numbers has been classified. In spite of this, several advisable subsidize factors have been recommended:
• Accelerated agriculture and pesticide use;
• Deprivation and poor bee nutrition;
• viruses, attacks by pathogens and protruding species – This includes the Varroa mite (Varroa destructor), the Asian hornet (Vespa velutina), the small hive beetle Aethina tumida and the bee mite Tropilaelaps;
• congenitally modified plants;
• Environmental changes (e.g. habitat fragmentation and loss)
Equivalently, for the National Stakeholders Conference on Honey Bee Health in the US (2013) also reiterates that a convoluted set factor is concord with Colony catastrophe Disorder.
The United Nations Environmental Programme (UNEP) consummate in a recent report in which is applicable knowledge on the decline of pollinates is not acceptable to validate that there is a worldwide pollinator crisis.
Which action are taken by the European Food Safety Authority (EFSA) related to bee losses?
A number of the EFSA’s Scientific Panels and Units contribute to this work. Among this dynamism, according to a report which was published by EFSA on honey bee mortality and the ways that colony losses are monitored in Europe. It indicates the general vulnerability of the examination systems under the investigation of 24 countries. In 2012, EFSA also announced a report from a task force which made suggestions on how this work should be ventured, and a major instructed document on the risk determination of defoliant in relation bees.
In the same year, an EFSA Scientific symposium on holistic accession to the risk assessment of multiple aggravation in bees congregate in response to the growing unanimity among scientists about the multifactorial ancestry of bee colony losses. In 2013 EFSA published risk assessments of the potential effects on bees of the pesticides thiamethoxam, imidacloprid, clothianidin and fipronil, showing that a risk for bees from exposure to these substances could not be ruled out.
A recent qualitative assessment of the continuing projects (March 2014) showed that there were still some extensive gaps in research in Europe, primarily on the joint effect of numerous factors, and on other species of bees than the honeybee. The determination also noted that projects on the prescriptions and on the vulnerability of bees to chemicals were also sporadic, as were those concentrate on protection goals, bee diversification and pollination services. This report presents a new set of suggestions for future scientific work.
