Raven is filming a three-part BBC documentary series, Operation Pollination, examining biodiversity in gardens, parks, towns, cities and the countryside, to be shown in autumn 2011.
As part of the programme she is leading a panel of experts in an attempt to design a new pollinator-friendly label for plants.
The team unveiled their plans during a seminar at the National Plant Show, where Raven appealed to the industry to contribute.
She said: "We made a programme called River of Flowers three years ago but you can't just talk about flowers without all the things that go with them. So I'm making a documentary about the role of insects - the aim is to drum up more interest and to get people to realise that we are at quite a critical point.
"People who aren't considered to be gardeners can pick up a plant but don't know if it's good for insects so one of the things that came out of it was the idea of devising a symbol that says it's an insect-friendly plant - it's a question of making sure that people outside the industry know what it means."
Raven is working with Northampton University's pollination ecologist Jeff Ollerton, RHS Wisley horticultural adviser Helen Bostock and horticultural consultant Doug Stewart to develop a list of plants that could be eligible to use the new symbol.
Raven appealed to delegates to get in touch with Stewart should they wish to be involved.
