15 صفحه اولThe Producer-Pollinator Dilemma: Neonicotinoids and Honeybee Colony Collapse
Neonicotinoid insecticides are the most important new insecticide class introduced in the past 40 years. They are the number one selling insecticide in the world, and are used on over 90% of the corn produced in the U.S. However, neonicotinoids could very likely be causing widespread and severe impairment to bee colonies, and possibly contributing to Colony Collapse Disorder (CCD). This is prob...
متن کاملDeformed wing virus implicated in overwintering honeybee colony losses.
The worldwide decline in honeybee colonies during the past 50 years has often been linked to the spread of the parasitic mite Varroa destructor and its interaction with certain honeybee viruses. Recently in the United States, dramatic honeybee losses (colony collapse disorder) have been reported; however, there remains no clear explanation for these colony losses, with parasitic mites, viruses,...
متن کاملPredicting Honeybee Colony Failure: Using the BEEHAVE Model to Simulate Colony Responses to Pesticides
To simulate effects of pesticides on different honeybee (Apis mellifera L.) life stages, we used the BEEHAVE model to explore how increased mortalities of larvae, in-hive workers, and foragers, as well as reduced egg-laying rate, could impact colony dynamics over multiple years. Stresses were applied for 30 days, both as multiples of the modeled control mortality and as set percentage daily mor...
متن کاملBEEHAVE: a systems model of honeybee colony dynamics and foraging to explore multifactorial causes of colony failure
A notable increase in failure of managed European honeybee Apis mellifera L. colonies has been reported in various regions in recent years. Although the underlying causes remain unclear, it is likely that a combination of stressors act together, particularly varroa mites and other pathogens, forage availability and potentially pesticides. It is experimentally challenging to address causality at...
