CrowdScience - Can I save the insects?

Buzzing insects that sting and fall into your food can be annoying. But perhaps we should think twice before taking aim with the fly swatter because bug populations around the world are in rapid decline. This worries CrowdScience listener Daria; she wants to know what will happen to our food production without the help from our tiny friends – the pollinators? And what can she do, as a city-dweller, to help the bugs?

The dollar value of agricultural services that insects supply – for free – is estimated to be 350 billion dollars worldwide. For scientists, a major challenge is the lack of long-term studies of insects on a global scale – in fact – entomologists worry that species are dying out faster than we can document their existence. The culprits, they believe, are climate change, invasive species, land-use and pesticides.

CrowdScience speaks to the scientists who want to save the bugs; one project capitalises on the chemical signals that attract certain species of pollinators while others are building ‘bee hotels’ to encourage native bees back into our cities.
