Killer Hornets v. Lovable Honeybees

     Giant Asian "murder hornets" seem poised to attack hives just as World Bee Day approaches on May 20, the birthday of Anton James, teacher in the world's first beekeeping school, founded by 18th century empress, Maria Theresa. Modern day beekeepers already struggle with the impact of collapsing honeybee colonies on the world's food supply.   

     With spring planting in progress in the Northern Hemisphere, a review of recent findings regarding bee health is important.

• Honeybee-killing pesticides containing neonicotinoids have been banned throughout the world,
• Global warming that makes hives too hot, strong winds and cold winter temperatures require protective hive designs,
• To compensate for the loss of pollen from fewer natural wildflowers, gardeners need to plant bee-friendly blooms such as zinnias, cosmos and lavender,
• Every effort should be made to leave clusters of woody debris and leaf litter undisturbed in breeding areas where bees forage and nest.

Local bees deserve nurturing care, since the introduction of foreign bees rarely compensates for hive collapse elsewhere. Not only can a different species be unable to adapt to a new area, it may introduce a foreign disease harmful to local bees.

     What can be done to protect honeybees from the exceptionally long stingers of attacking hornets? Maybe the research that shows some success in eliminating malaria-carrying mosquitoes might help.

Tour Sites Beyond A Country's Capital

News coverage rightly focuses on the capitals of countries. In governing centers, elections, coups. terrorist attacks, and earthquakes deserve attention, because they affect the political directions and needs of a country. Nonetheless, capital-centered news draws attention away from much that a country has to offer. This realization came home to me this morning, when I heard news warning U.S. citizens to avoid travel to China during this period of trade and spying tensions.

     Consider some of the sights and activities visitors to China have discovered  in cities beyond Beijing. Find a map or globe and locate:

Yanqing - North of Beijing, visitors will see flower exhibits from over 100 countries at the International Flower Festival with the theme, "Live Green, Live Better," which begins April 29, 2019. From a nearby 4-story tower, tourists also will be able to see the Great Wall of China when smog does not obstruct the view. In 2022, this city will be the site of some Winter Olympic events.

Chongli - North of Yanqing, this city also will be the site of some Winter Olympic events in 2022.

Moving southeast from Beijing toward China's coast, locate:

Qingdao - This deep water port was annexed by Germany and used by the German navy in 1887, captured by Japan in 1914, and returned to China in 1922. Germany's lingering influence is evident in the city's famous brewery, Tsingtao; a German Protestant church; and the Governor's House Museum. Prior to September, 2019, you may have been able to see movie stars coming and going from what was expected to be this new center of Chinese filmmaking before authoritarian control caused investors to leave.

Suzhou - Farther down the eastern coast, west of Shanghai, is China's traditional cultural center for intellectuals known as "the Venice of the East" because of its picturesque canals and stone bridges. A museum here traces silk production, and the UNESCO heritage Humble Administration's Garden and the Garden of Cultivation attract millions of tourists.

Xiamen - Still farther south, west of Taiwan, the deep water harbor, also known as Amoy, was once a pirate hideaway and tea exporting port. Now, it is known for its beaches and earthen Hakka roundhouses. A ferry takes visitors to Gulangyu Island to see the former mansions of European and Japanese traders.

Haikou - At the base of China, east of Vietnam, this city on Hainan Island is a tropical beach with water sports and arcades.

In western China, there are at least two notable cities, one in the south and one in the north.

Chengdu - If you've seen a Giant Panda at a zoo, it probably came from the research and breeding center, established in 1987, that you're welcome to visit at Chengdu, far west of Shanghai.

Lanzhou - This stop on China's ancient Silk Road map is the gateway to western China. It is a multicultural city, with Chinese Han, Muslim, and Tibetan influences, at the Zhongshan Bridge over the Yellow River. Lanzhou beef noodles and barbecued meats are local specialties.

     Beyond the capital of any country, what are the other significant cities you would like to visit?

Plant Flowers, Help Bees

To bees, a sweeping lawn, parks, and golf courses look like deserts, writes Thor Hanson in Buzz: The Nature and Necessity of Bees. Without pollen from flowers, bees cannot survive and neither can people without the pollination bees provide for many food crops. Of the 20,000 different species of wild bees, some 40% are in decline or threatened with extinction. Domestic bees suffer from lost habitat, parasites, pesticides, and diseases picked up when transferred from farm to farm.

After "colony collapse" began to cause hive losses, dangers to bees and ways to help them often have been covered in previous posts:

Bumble Bees Have Special Needs

Like honey bees, fruit farmers depend on bumble bees to pollinate their crops. Unlike honey bees, that shy away from working in cool climates, bumble bees even will be out pollinating in wind and rain. They need flowers constantly available to supply nectar and pollen, because they don't store food in hives the way honey bees do.  Cranberry blossoms feed bumble bees that pollinate cranberry crops in the middle of summer, for example, but the queen also needs food in spring, when she lays eggs, and in late summer to get her through the winter. Backyard gardeners can help farmers by planting wildflowers that grow in as many seasons as possible.

     To avoid using seeds and plants treated with bee-killing insecticides, gardeners are urged to shop at nurseries or to find plants from organic sources, since efforts to require pesticide and insecticide labeling have been unsuccessful. Seeing an endangered rusty patched bumble bee on a flower is cause to take a photo and report your sighting to bumblebeewatch.org. The site provides much more information about bumble bees and where rare ones have been photographed.

   

   

Meet the Farmer Behind the Produce Label

A label on your banana tells its country of origin, but the UK's Fairtrade Foundation (fairtrade.org) site tells you about the farmers who grow and harvest your bananas, what benefits they receive, and where you can buy Fairtrade certified bananas.

The Fairtrade site also provides the background of other produce: cocoa, coffee, cotton, flowers, sugar, and tea. Something to read while enjoying your banana.

World's Food Supply Needs Bees & Bees Need Help

One study found 40% of bee and butterfly pollinators are in decline around the world. As if bees didn't have enough problems with the neonicotinoid type of insecticide that has been causing their colonies to collapse since 2006, now they have to deal with the effects of climate change. When spring-like warming occurs too early, flowers can bloom before bees are ready to make their rounds. Crops of at least 140 nuts, fruits, and vegetables can suffer from a lack of pollination.

     In the US, clocks are about to be moved an hour ahead this weekend to signal the beginning of daylight saving time and the time to get seeds for planting flowers and food crops on commercial farms and in backyards, rain gardens at the curb, and community plots. The Sierra Club has been sending members packets of what the organization calls a "Bee Feed Flower Mix." These packets contain seeds for bee-tasty nectar and pollen from forget-me-nots, poppies, asters, blue flax, white sweet alyssum, lavender, fleabane daisies, and purple coneflowers. What is important is the seeds in these packets are Untreated.

     Untreated seeds are important because treated seeds, such as corn and soybean seeds, are coated with neonicotinoid insecticide to kill pests as soon as the seeds sprout. Frequent exposure to neuro-toxic pesticides that spread through a plant's leaves, pollen, and even nectar damage a bee's nervous and immune systems. While insects destroy plants, so too are strawberries, avocados, peaches, almonds, and other crops lost due to a lack of pollination by bees.

     Presented with a decade of evidence about simultaneous bee colony collapse and neonicotinoid use, the European Union suspended the use of neonicotinoid in 2013. In the US, the Department of Agriculture continues to study the problem, and the Saving America's Pollinators Act of 2015 failed to get out of a House of Representatives subcommittee.

     US consumers and farmers began to take matters into their own hands. There have been consumer campaigns against stores that sell neonicotinoid-treated plants. Gardeners started to grow bee-friendly flowers and to leave woody debris, leaf litter, and bare soil where bees can breed. You can find more on this subject in the earlier post, "Be Kind to Bees."

     Some farms also began to meet the bee health challenge. Besides planting vegetables, an organic farm couple in Minnesota planted flowering dogwood and elderberry hedgerows to attract bees, butterflies, and other insects that pollinate their crops. General Mills, a company that uses honey, fruit, and vegetable ingredients requiring pollination, is working with the Xerces Society and the Department of Agriculture to preserve pollinator habitat on 100,000 acres of US farmland. A plan to grow flowers and shrubs in narrow strips around crop fields is designed to restore seven million acres of land for pollinators in the next five years. But for farmers who usually grow single crops, a shift to diversify with flowers that attract pollinators is not easy. It requires analysis of farm land, how wet and dry it is, for example, and which plants will not attract the insects that could destroy their farm's crops.

     The battle to save bees, and the world's food supply, continues.
