- Domesticated Bees Shortage (NationalGeographic.com)
"Decades of disease and overuse of pesticides have put the squeeze on populations of the domesticated honeybee. As a result, farmers are increasingly left with fields of flowering crops that fail to bear fruit."
"Since some 15 to 30 percent of the food we humans eat directly or indirectly depend on the pollination services of bees, scientists say the problem threatens to take some excitement—and potentially abundance—from our diets." 10-04
- Bees - Males Have Half the Chromosomes (NationalGeographic.com)
"Bees, wasps, and ants from the group of insects known as the hymenopteran order and other invertebrates have males with only half the usual complement of chromosomes. These insects and invertebrates comprise 20 percent of all animals." 10-04
- Bees Endangered by Mites and Pesticides (NationalGeographic.com)
"Bees, via pollination, are responsible for 15 to 30 percent of the food U.S. consumers eat. But in the last 50 years the domesticated honeybee population—which most farmers depend on for pollination—has declined by about 50 percent, scientists say."
"Unless actions are taken to slow the decline of domesticated honeybees and augment their populations with wild bees, many fruits and vegetables may disappear from the food supply, said Claire Kremen, a conservation biologist at Princeton University in New Jersey." 10-04
- -05-07-07 Bees Disappearing at an Alarming Rate (CBS News)
"According to the Apiary Inspectors of America, a hive-tracking group, more than a quarter of the country's bee colonies have been lost — more than half-a million bee colonies that have simply vanished. What is actually happening — and what repercussions could it have on your dinner table?" 05-07
- Virus May Be Causing Bees to Disappear (PBS.org)
"A virus from Australia may be the culprit in the mysterious deaths of tens of millions of honeybees in the past year, according to a study published Thursday in the journal Science."
"Colony Collapse Disorder affected 23 percent of U.S. beekeepers last year. Affected beekeepers lost an average 45 percent of their bees to the phenomenon -- the bees simply disappeared, leaving empty or nearly empty hives." 05-07
- New Clues in Mass Death of Bees (Time.com)
"In late 2006, something strange began to happen to America's honeybees. Colonies that were once thriving suddenly went still, almost overnight. The worker bees that make hives run simply disappeared, their bodies never to be found. Over the past couple of years, nearly one-third of all honeybee colonies have collapsed this way, which led to a straightforward name for the phenomenon: colony collapse disorder (CCD)."
- -09-10-09 Saving Bees: What We Know (New York Times)
"The first alarms about the sudden widespread disappearance of honeybees came in late 2006, and the phenomenon soon had a name: colony collapse disorder. In the two years that followed, about one-third of bee colonies vanished, while researchers toiled to figure out what was causing the collapse."
"Honeybees are just one of the many species we depend on that are struggling mightily to withstand a steady stream of novel parasites and pathogens they have never encountered before, and have no tools to defend against." 09-09
- -What Is Killing Bees (CBS News)
"CBS News correspondent John Blackstone reports in each of the past four years about one-third of America's 2.5 million honeybee colonies have been wiped out. University of Montana researcher Jerry Bromenshenk has been searching for the killer. After screening bees for 30,000 disease markers a group of scientists led by Bromenshenk say they have found a probable cause."
"The kind of virus they discovered is common in other insects but very rarely seen in bees. The virus seems to kill only when the bees are also infected with a parasite, a type of fungus."
"Bromenshenk said, 'It looks like is that the bees can tolerate either one alone.' But, 'When you combine the two - that tends to become lethal in a hurry.' "
"That combination may help beekeepers. While there is no way to treat the unusual, new virus, the parasite can be killed by a fungicide. Bromenshenk said beekeepers can 'buy those treatments and apply them.' "
"As the main pollinator for most fruits and vegetables, honeybees play a vital role in producing about 30 percent of our food. So it's important to all of us that scientists are now closing in on both the cause and the cure of the honeybee die-off." 10-10
- Bees Disappearing Tied to Pesticides (MSNBC News)
"A widely used farm pesticide first introduced in the 1990s has caused significant changes to bee colonies and removing it could be the key factor in restoring nature's army of pollinators, according to two studies released Thursday."

- -07-20-13 Editorial: Ban the Pesticide That Is Killing Bees? (CBS News)
"Last month, 50,000 bumble bees died after trees in Wilsonville, Oregon were sprayed with dinotefuran, the neonicotinoid ingredient in Safari pesticide. This was the largest bee die-off ever recorded."
"With bee populations declining across the around the country at an alarming rate, I urge you to support the "Save America's Pollinators Act" to restrict the use of these chemicals until we can be assured that they are safe and being used properly."
"From flowers to chocolate, berries to tequila, pollinators are integral to the planet, economy, and many aspects of our lives. In fact, the USDA estimates that about one in every three bites of food is either directly or indirectly made possible because of bee pollination. Both our environment and food supply are inextricably tied to the welfare of bees, making the decrease in bee population a cause for great alarm." 07-13

Provides sources of information on Antlions, Beetles, Dragonflies, Mites, Termites, Ants, Butterflies, Fleas, Mosquitoes, Ticks, Arachnids, Cicadas, Flies, Moths, Wasps, Bees, Cockroaches, Mayflies, and Praying Mantids. Includes a search engine. 2-01
- -Ants (Wikipedia.org)
"Ants are social insects that belong to the same order as the wasps and bees. They are of particular interest because of their highly organized colonies or nests which sometimes consist of millions of individuals."
"Up to a third (33%) of the terrestrial animal biomass has been estimated to be made up of ants and termites."
"Termites, sometimes called white ants, though similar in social structure are not even closely related to ants." 01-07
- -Has the Majority of the "Missing" Mass of the Universe Been Found? (Time.com)
"As you might have heard if you pay attention to these things (and will be distressed to learn if you don’t) up to 80% of the matter in the universe is simply missing. The Milky Way spins so fast it would fly apart if the gravity of some invisible matter weren’t holding it together. Clusters of galaxies, buzzing around one another like angry bees, would similarly fragment and disperse. And when you run the gravitational numbers, the mysterious matter that keeps all that cosmic disintegration from happening should outweigh the familiar stuff by about four-to-one."
"Just as researchers working at Europe‘s Large Hadron Collider last year announced that they had bagged the Higgs Boson, so did investigators this week reveal that they’ve found compelling evidence for a type of theorized particle known as a WIMP—for weakly interacting massive particle—and that at least one form of it may be the dark quarry they’ve been hunting for 80 years." 04-13
- -The Death of the Bee (Swampland.Time.com)
"The beepocalypse is on the cover of TIME, but it looks like managed honeybees will still pull through. Wild bees—and wild species in general—won't be so lucky in a human-dominated planet."
"More recently, beekeepers have been seeing fewer cases of CCD proper [Colony Collapse Disorder], but honeybees keep dying and bees keep collapsing. That’s bad for our food system—bees add at least $15 billion in crop value through pollination in the U.S. alone, and if colony losses keep up, those pollination demands may not be met and valuable crops like almonds could wither."
"More than the bottom line for grocery stores, though, the honeybee’s plight alarms us because a species that we have tended and depended on for thousands of years is dying—and we don’t really know why. Tom Theobald, a beekeeper and blogger who has raised the alarm about CCD, put that fear this way: 'The bees are just the beginning.' ” 08-13
- Termites (Wikipedia.org)
"Like ants, and some bees and wasps—which are all placed in the separate order Hymenoptera—termites divide labor among castes, produce overlapping generations and take care of young collectively. Termites mostly feed on dead plant material, generally in the form of wood, leaf litter, soil, or animal dung, and about 10% of the estimated 4,000 species (about 3,106 taxonomically known) are economically significant as pests that can cause serious structural damage to buildings, crops or plantation forests. Termites are major detritivores, particularly in the subtropical and tropical regions, and their recycling of wood and other plant matter is of considerable ecological importance."
