That is the question posed in the first episode of a new series of science show 10 Things To Know About... on RTÉ1 on Monday at 8.30pm.
Cork presenter and Echo columnist Kathriona Devereux and co-host Jonathan McCrea start off by asking if insects could hold the solution to feeding the world in a more sustainable way.
Insects have a high protein content and carbon-friendly breeding methods, and with three types of insects already in use in the EU, the team check out the latest Irish research into edible insects.
Unfortunately, not all insects are helpful to the food chain. Grain aphids carrying Barley Yellow Dwarf Virus (BYDV) can devastate cereal crops, reduce the yield by on average 30%, but can be as high as 80% in optimalconditions.

Also in the series, Fergus McAuliffe, of Farran, returns to host his ‘Curious Chronicles’ segment, starting by championing that war-time medical marvel: the humble maggot...
This is the eighth series of 10 Things To Know About... which showcases and celebrates the Irish science behind aspects of modern life.
