Landing lights for bumblebees
Date:10/11/2010

Zealand also analysed how the stripy patterns are formed along the veins of the common snapdragon. They showed that two signals interact to create the stripes.

"Complex colour patterns such as spots and stripes are common in nature but the way they are formed is poorly understood," said author Dr Kathy Schwinn from the New Zealand Institute for Plant & Food Research.

"We found that one signal comes from the veins of the petals and one from the skin of the petals, the epidermis. Where these signals intersect, the production of red anthocyanin pigments is induced."

Professor Douglas Kell, Chief Executive of BBSRC, which part-funded this research through strategic funding to JIC, said: "Pollinator insects, such as honeybees, have a highly significant role in agriculture and any reduction in numbers is economically damaging and risks our food security. Much of the food on our plates is reliant on insect pollination. BBSRC is investing in research to understand how we can arrest pollinator decline and this study shows how horticulturalists and gardeners can encourage bumblebee populations."
