Summary

Without honey bees the world would be a different place. There would be no honey, no beeswax for candles, and, worst of all, barely a fruit, nut, or vegetable to eat. So imagine beekeeper Dave Hackenburg's horror when he discovered twenty million of his charges had vanished. Those missing bees became the first casualties of a mysterious scourge that continues to plague honey bee populations today. In The Hive Detectives, Loree Griffin Burns profiles bee wranglers and bee scientists who have been working to understand colony collapse disorder, or CCD. In this dramatic and enlightening story, readers explore the lives of the fuzzy, buzzy insects and learn what might happen to us if they were gone.

The Hive Detectives: Chronicle of a Honey Bee Catastrophe by Loree Griffin Burns, illustrated by Ellen Harasimowicz Text copyright © 2010 by Loree Griffin Burns. All rights reserved. Put on your veil, grab your hive tool, and light up your smoker . . . . . . we're going into a beehive. Before we begin, remember this: Honey bees are gentle insects. Gentle? you ask. But don't they have giant stingers on their rear ends? Well, yes, most bees do have a stinger at the tip of the abdomen. But they only use it in emergencies. If you move slowly and deliberately (no jerks in the bee yard!) and remember not to block the hive entrance (bees hate to find a strange body between them and the entrance to their hive), you can spend an enjoyable afternoon with thousands of honey bees and walk away without a single sting. Mary Duane does it all the time. Mary is a hobbyist beekeeper. She keeps a small number of honey bee hives in her backyard for the pleasure of working with the bees and, of course, for the honey. Every week or two, from early spring until fall, Mary opens and inspects each of her hives to be sure the family of bees inside is healthy and safe. If anything is wrong with the colony--and, unfortunately, there are many things that can go wrong--Mary will see signs during the inspection. Her goal as beekeeper is to recognize these signs and take the steps needed to correct them. It's not an easy hobby, but the rewards, according to Mary, are many. "When you work with bees you have to pay close attention to what you are doing," says Mary. "Everything else in your life drops away. The bees are fascinating, they help the environment, and the honey is great, but mostly I love that keeping bees forces me to be mindful." In nearly ten years of beekeeping, Mary has been stung about twenty times--not bad when you consider she's handled millions of bees. Most of those stings happened early on, when Mary was new to working with honey bees. Now that she is used to the sights and sounds of an apiary, or bee yard, Mary is more relaxed and stings are rare. She wears a veil, of course, to protect her face, and she keeps sting remedies in her bee box, but she works her bees barehanded. "I started off wearing gloves, but I find that I'm more gentle without them," Mary says. She pats the top of her bee box and adds, "If I come across an ornery hive, then I put my gloves on like anybody else." Mary also keeps a smoker handy. Any worries the bees have about Mary poking through their home--worries they communicate with each other by releasing a smelly chemical called alarm pheromone--will be masked by the smell of smoke. Unable to smell alarm pheromone, the majority of bees in the hive don't realize anything is amiss and, as a result, remain calm during the inspection. To prepare the smoker, Mary fills it with dry pine needles, drops in a lit match, and fans the flames with air from an attached bellows. Once the needles are burning well she closes the top and a thin line of smoke issues from the metal spout. Like most modern beehives, Mary's consist of several boxes, called supers, stacked one atop the other in a towerlike structure. The supers come in different depths--and depending on the beekeeper, in different colors, too--but inside, all supers are the same: ten rectangular frames hang side by side. Each frame provides a foundation on which the bees can build their wax honeycomb. They fashion rows and rows of hexagonal cells that will eventually be used to store food and raise young bees. Supers and frames are designed so that the honeycomb is arranged just as it would be in a wild hive. Of course, the removable frames and stackable supers make handling a man-made hive much easier than handling a wild hive in a hollow tree. Mary begins her inspection at the top of a hive and works her way down. Because her hive tower is fitted with a queen excluder--a metal screen with openings large enough for worker bees but too small for a queen bee to squeeze through--the contents of each super is predictable. Above the queen excluder, in the part of the hive the queen can't reach, are the so-called honey supers. These will be full of worker bees storing nectar and turning it into honey. Below the queen excluder, toward the bottom of the hive, are the brood boxes. These are the only supers the queen has access to, and so they contain the result of her hard work: the colony's young and developing bees. Since developing bees are called brood, this part of the hive is often called the brood nest. To get started, Mary grabs what looks like a small metal crowbar--beekeepers call it a hive tool--and pries open the first honey super. "We beekeepers like to say that whoever invented the hive tool should get a Nobel Prize," Mary jokes as she works the hive tool into position. "It's that useful." Hive tools are necessary because bees seal every crack and crevice in the hive with propolis, a gummy substance they make from the sap of plants and trees. Propolis protects the bees by keeping wind, water, and pests (such as ants and spiders) out of the hive, but it is a hassle for beekeepers. "It's sticky!" says Mary. "There has never been a hive I couldn't open, but sometimes it takes a bit of muscle." When she finally opens the top honey super and pulls out a frame, the news is good. "Look at all that honey," she exclaims, pointing at the rippled wax surface the bees are crawling over. The bees made the wax and used it to cover, or cap, honey-filled comb cells. Though most cells on this first frame are capped, others are open, and sunlight bounces off the liquid nectar inside them. The bees collected this nectar from flowers in and around Mary's yard. When it is fully ripened into honey--a process that involves a little bee spit and a lot of evaporation--the bees will cap it, too. Eventually they will fill every cell on every frame of this super with honey. Only then will Mary collect and bottle it. When she is satisfied with her inspection of the first honey super, Mary removes the entire box from the top of the hive tower and sets it gently on the ground. Then she begins to inspect the honey super below it. When this box also passes inspection, Mary is ready to move deeper into the hive. She pries off the queen excluder and takes her first look inside the brood nest. "This one is just boiling with bees!" she exclaims. She blows smoke gently across the top of the box and then, just as she did in the honey supers, removes a single frame. Thousands of honey bees come with it, but Mary hardly notices them. Believe it or not, the bees hardly notice her either. "This is beautiful," she says, gazing at the frame through her veil. "Perfect. I couldn't be happier. There's a great brood pattern." She points beneath the crawling bees to an area of honeycomb covered with what looks like a graham cracker crust. The crust is actually more wax. Unlike the fresh wax that covers cells in the honey supers, the wax in the brood nest is recycled. It is darker in color and drier in appearance. In the brood nest, the wax-capped cells contain young bees in the final stages of their development. When the bee in each cell is fully developed, it will chew through the wax and join the hive. "And here are some larvae," Mary adds, pointing out a few open cells, each housing a curled white grub. Eventually, when these larvae grow big enough, their cells will be capped and they, too, will begin the process of transforming into adult bees. Mary lifts another frame from the brood nest, holds it up to the sunlight, and squints at it. She is hoping to see signs of the first stage of bee development: eggs. Honey bee eggs look remarkably like grains of white rice, although they are smaller and hard to see with the naked eye. Eggs, larvae, and capped brood are all signs that this colony's queen is healthy. Although Mary doesn't see the queen herself--she is lost among the thousands and thousands of bees in the brood nest--the presence of young larvae prove she is here, somewhere. "She's doing a nice job," Mary says thoughtfully as she continues to study the brood nest. In addition to developing bees, Mary finds capped honey, nectar, and pollen in the brood nest. Worker bees use these stores to feed themselves and the growing larvae. Mary examines each frame for signs of disease (thankfully, there are none) and for signs that the colony might soon swarm, or split into two separate colonies. Although swarming is a normal and healthy activity in the beehive, it limits honey production. Most beekeepers work hard to prevent it, and Mary is pleased to find no signs of swarming today. When the inspection is finished, Mary rebuilds the hive frame by frame and super by super, carefully putting each component exactly where it was when she began. She records everything she has observed in her notebook and then takes a few minutes to contemplate the hive she has just visited. At the base of the hive tower is the entrance, and bees are coming and going at an incredible rate. Field bees, the ones responsible for collecting food for the hive, arrive with clumps of bright orange-yellow pollen. Mary knows these bees are also carrying nectar, and she can't help but smile as they lumber onto the landing board in front of the hive entrance. "They can barely negotiate the landing!" she says. Guard bees examine the arriving bees to be sure they belong here, and receiver bees stand ready to unload the incoming nectar. When the guards are satisfied, the field bees regurgitate nectar directly into the mouths of receiver bees, who quickly store it inside the hive. New field bees constantly emerge from the hive and fly off in search of more food. "It's like a busy airport strip," says Mary. She touches the side of the hive before moving toward the next tower in her apiary. There is little time for rest in a healthy and productive bee yard . . . not for the bees, and not for their keeper.
