Tiny technology creates a buzz [Environment]
posted January 17 2014 11:05.33 by spic0m




"What if I told you that insects in the environment may be able to tell us about the world they live in? Imagine it; they could reveal changes in climate, the presence of dangerous gases or even the arrival of pests. Now you might think this a flight of fancy and tell me to buzz off, but this may not be so far from reality.

Our new research project is using tiny sensors that act like your car's e-tag and attaching them to the backs of honey bees.

What the?

You heard right - bees with a chip on their shoulder, or on their back at least.

These tiny 2.5mm x 2.5mm chips relay data to recorders placed around hives and known food sources. We're not talking about one or two wired up insects here, 5,000 tags are currently being attached to honey bees in Hobart and released into the natural environment.

And why would our researchers do that?

Collecting bee movement information at this scale is a world first and will allow researchers to generate a four dimensional model (three dimensions over time) of bee behavior and the way these insects move through the landscape. This information is needed on a global scale as wild honey bee populations are dropping drastically or vanishing all together. In some instances this is because of the parasitic Varroa mite. In others it's a case of Colony Collapse Disorder, which is believed to be caused by diseases and agricultural pesticides.

CSIRO's Dr Paulo de Souza leads the project and talks about why it is so important to protect these often feared insects."
