ARTICLE: Honeybees as plant ‘bodyguards’ -

“Honeybees are important to plants for reasons that go beyond pollination, according to a new study published in the December 23rd issue of Current Biology, a Cell Press publication. The insects’ buzz also defends plants against the caterpillars that would otherwise munch on them undisturbed.

The researchers, led by Jürgen Tautz of Biozentrum Universität Würzburg, Germany, earlier found that many caterpillars possess fine sensory hairs on the front portions of their bodies that enable them to detect air vibrations, such as the sound of an approaching predatory wasp or honeybee.

“These sensory hairs are not fine-tuned,” Tautz said. “Therefore, caterpillars cannot distinguish between hunting wasps and harmless bees.” If an “unidentified flying object” approaches, generating air vibrations in the proper range, caterpillars stop moving or drop from the plant…

“Our findings indicate for the first time that visiting honeybees provide plants with a totally unexpected advantage,” the researchers said. “They not only transport pollen from flower to flower, but in addition also reduce plant destruction by herbivores.”

…If crops are combined with attractive flowers in such a way that honeybees from nearby beehives constantly buzz around them, it may lead to significantly higher yields in areas with lots of leaf-eating pests—a notion Tautz’s team intends to test. “Our finding may be the start of a totally new biological control method,” he said.”

Honeybees, the new urban dwellers

“Honeybees play a vital role in many areas of our lives – they pollinate our crops and medicinal plants – but their population has decreased by 30% since 2008. Could our towns and cities now provide them with a safe haven?


Major cities around the world such as London, New York, Hong Kong and Paris are encouraging bees to set up home in the city. Rooftops, small urban gardens and even balconies are providing potential safe-havens for honeybees, our newest and, in many ways, most-important urban dwellers.

The future of mankind is dependent on the survival of the bee.

Honeybees are responsible for pollinating 80% of our food crops worldwide, therefore risks to their health threaten our own food security. Many medicines, an enormous part of our textile industry and, of course, perfumes and cosmetics also rely on flowers and plants that are pollinated by bees.

In short we have the honeybee to thank for the basic components of our daily lives, from the food we eat and the drugs we need, to the clothes we wear – and that’s without beginning to consider items of luxury.

However, the honeybee population has decreased by 30% since 2008 and the reasons for their poor health are multifaceted. Today the rural environment poses severe health risks to bees through intensive farming methods and the use of pesticides.

“Mono crop” farming means that many bees now have a “mono pollen diet”. This could be detrimental to their health as pollen provides bees with protein; as each pollen variety contains different nutrients that are needed to maintain good health, missing out on certain nutrients leaves bees vulnerable to diseases.

Bees that miss out on a balanced diet can also become more susceptible to parasites, such as the varroa mite, or colony collapse disorder, which is believed to be caused by a combination of fungal and viral infections.

Such threats mean the honeybee could potentially have a better chance of survival in urban environments.

City living potentially provides a rich and varied source of pollen that gives bees all the nutrients and enzymes they require for their good health.

Bees that live in the city may also benefit from new kinds of beehive designs that have been created specifically for urban bees.

This growth in the urban honeybee population, and the need for it to be encouraged, calls for not only new type of homes which are suitable for beekeeping, but also a complete re-examination of our relationship with honeybees where they live beside us and we welcome their presence.”

“If the bees disappeared, then man would only have four years left to live. No more bees, no more pollination, no more plants, no more man.”

“Colony collapse disorder is the subject of this environmental documentary. As bee colonies around the United States disappear, scientists and beekeepers struggle to find the reason why and ascertain the impact on humans and the planet. Longtime beekeepers and newcomers alike are faced with economic ruin as they try to keep their hives healthy and prevent this crisis from wreaking havoc on a world that depends on pollination to sustain agriculture.”

Breakfast without Bees?

“Without honeybees, many foods included in the breakfast [on top] would become too rare for most people to afford. Shortages would affect an array of fruits, as well as jams and jellies, almonds and even milk, because dairies use alfalfa (which needs pollinators) as a protein-rich feed for dairy cows.” – ScientificAmerican.com
