Abstract

Is electromagnetism one of the causes of Colony Collapse Disorder? A work plan for testing this hypothesis Marie-Claire Cammaerts. Is electromagnetism one of the causes of the CCD? A work plan for testing this hypothesis. Journal of Behavior. 2(1): 1006. Published Mar 28, 2017. Abstract The decline of domestic bees all over the world is an important problem still not well understood by scientists and beekeepers, and far from being solved. Its reasons are numerous: among others, the use of pesticides and insecticides, the decrease of plant diversity, and bee's parasites. Besides these threats, there is a potential adverse factor little considered: manmade electromagnetism. The production of electromagnetic waves by human settlements, cellphones relay and power lines largely increases nowadays. Bees are very sensitive to this electromagnetism. The present paper suggests two simple experimental protocols for bringing to the fore the potential adverse effect of electromagnetism on bees and to act consequently. The first one is the observation of bees' avoidance of a wireless apparatus; the second one is the assessment of colonies' strength and of the intensity of the electromagnetism field (EMF) surrounding them. If bees avoid a wireless apparatus, if hives in bad health are located in EMF of a rather high intensity, it can be presumed that bees are affected by manmade electromagnetism. This should enable searching for palliative measures. jscimedcentral.com

Main findings

The paper proposes two experimental protocols to test whether manmade electromagnetism could adversely affect bees: (1) observing bees’ avoidance of a wireless apparatus and (2) assessing colony strength alongside measurement of EMF intensity around hives. It suggests that if bees avoid the apparatus and if weaker hives are located in higher-intensity EMF, this could support the presumption that bees are affected by manmade electromagnetism.
