“So, caffeine in nectar is likely to improve the bee’s foraging prowess while providing the plant with a more faithful pollinator.” In the study, researchers found that the nectar of citrus and coffea species often contained low doses of caffeine.

“In turn, bees that have fed on caffeine-laced nectar are laden with coffee pollen and these bees search for other coffee plants to find more nectar, leading to better pollination. “Remembering floral traits is difficult for bees to perform at a fast pace as they fly from flower to flower and we have found that caffeine helps the bee remember where the flowers are. Study leader Geraldine Wright, reader in neuroethology at Newcastle University, U.K., said the effect of caffeine benefits both the honeybee and the plant. Publishing in Science the researchers show that in tests, honeybees feeding on a sugar solution containing caffeine, which occurs naturally in the nectar of coffee and citrus flowers, were three times more likely to remember a flower’s scent than those feeding on just sugar. The benefits are synergistic to both bees and plantsĬientists have shown that caffeine improves a honeybee’s memory and that helps the plant recruit more bees to spread its pollen.

Gary Smart, a MAFRI farm management adviser, presents his analysis of the most profitable crops this season. In a list of the top eight best-performing crops based on net returns per acre, Smart pegged soybeans as the next best, followed by sunflowers and canSee MONEY-MAKER on page 6 » On Smart’s cost-of-production spreadsheets, winter wheat should net $76.25 an acre (total returns of $393.96 per acre minus $317.71 in costs). “Winter wheat - it’s pretty tough to plant that now - but whoever’s got it in the ground is looking pretty good,” Smart said during a presentation at the recent Young and Beginning Farmers Conference. But farmers who seeded winter wheat last fall will be pleased to hear that their dart is likely to land dead centre, says Gary Smart, a farm management specialist with Manitoba Agriculture, Food and Rural Initiatives in Somerset. Ith highly variable costs and prices, choosing the most profitable crop to grow each spring is a bit like throwing darts at a moving target.
