Bees force plants to flower early by cutting holes in their leaves
Hungry bumblebees can coax plants into flowering and making pollen up to a month earlier than usual by punching holes in their leaves.
Bees normally come out of hibernation in early spring to feast on the pollen of newly blooming flowers. However, they sometimes emerge too early and find that plants are still flowerless and devoid of pollen, which means the bees starve.

Turkish beekeepers risk life and limb to harvest ‘mad’ honey
Mad honey, known to the Greeks and Romans, is still produced in small quantities by beekeepers in parts of Turkey where indigenous rhododendron species make a potent neurotoxin which ends up in local honey.Read the article.
Pesticide made from spider venom kills pests without harming bees
Funnel-web spiders have neurotoxins in their bite that can kill an adult human yet they might turn out to be our allies if the small hive beetle ever reaches the UK.
Scientists at the University of Durham and Fera Science think the spiders may provide the weapon we need to stop the beetles.
The spider venom contains a cocktail of ingredients and one of them – Hv1a – is toxic to most insects, including the small hive beetle, but does not seem to affect bees or humans.
Hv1a needs to be injected to be effective. Just swallowing the toxin is ineffective as it is degraded in their gut. To get round this the team have bound Hv1a to a molecule from the common snowdrop which effectively carries it through the gut barrier.
In the laboratory the team fed the “fusion protein” in a sugar solution to beetles and their larvae. Within a week, all the beetles and larvae were dead.
Next step was to put beetle eggs on bee comb with brood, and spray with the compound. The honeycomb and bees survived virtually untouched, but most of the new beetle larvae died.

World’s largest bumblebee under threat.
The Patagonian bumblebee, the worlds largest bumblebee, is under threat from the import of species native to Europe.The growth of the bumblebee trade for agricultural pollination since the 1980s has been identified as one of the top emerging environmental issues likely to affect global diversity.Follow this link to read the article.
