How Pollination is Important to Bees

How Pollination is Important to Bees

It has often been said that bees are responsible for one out of every three bites of food we eat. Most crops are grown for their fruits, nuts, seeds, fiber, and hay, which require pollination by insects. Pollinating insects also play a critical role in maintaining natural plant communities and ensuring the production of seeds in most flowering plants. Pollination is the transfer of pollen from the male parts of a flower to the female parts of the same species, which results in the fertilization of plant ovaries and the production of seeds. The primary insect pollinators, by far, are bees. While European honey bees are the best known and widely managed pollinators, hundreds of other species of bees, primarily solitary ground-nesting species, contribute some level of pollination services to crops and are very important in natural plants communities.

Bees make excellent pollinators because most of their life is spent collecting pollen, a source of protein that they feed to their developing offspring. When a bee lands on a flower, the hairs all over the bees’ body attract pollen grains through electrostatic forces. Stiff hairs on their legs enable them to groom the pollen into specialized brushes or pockets on their legs or body and then carry it back to their nest. Individual bees tend to focus on one kind of flower at a time, which means it is more likely that pollen from one flower will be transferred to another flower of the same species by a particular bee. Many plants require this kind of pollen distribution, known as cross-pollination, to produce viable seeds. The business of collecting pollen involves a lot of energy, and so many flowers attract and reward bees with nectar, a mixture of water and sugars produced by plants.

 

Most bee species dig nests in soil, while others utilize plants, either by boring holes in pithy plant stems or wood or by nesting in galleries made by wood-boring beetles in trees or other preexisting cavities. Bumblebees are known to nest in abandoned rodent burrows, and feral honey bees are known to nest in tree hollows. Bees use a variety of materials to build their nests. Most bees line their nest cells with a waxy material they produce themselves, but others use pieces of leaves, small pebbles mixed with resin from tree sap, or mud to form the cells they lay their eggs.

Bee communities, both wild and managed, have been declining over the last half-century as pesticide use in agricultural and urban areas increased. Changes in land use have resulted in a patchy distribution of food and nesting resources. Concerned bee researchers recently met to discuss the current pollinator status in North America and to publish a report about it. Since 2007, there have been several reports in the media about the mysterious disappearance of large numbers of honey bees called colony collapse disorder. This has many growers concerned about how they will continue to be able to pollinate their crops. Now more than ever, it is critical to consider practices that will benefit pollinators by providing habitats free of pesticides, full of nectar and pollen resources, and ample potential nesting resources.

A Bee’s Life

August 18, 2021 Uncategorized

 A Bee’s Life

A honeybee’s life is quite full as they spend their days caring for their colony. Each day is full of purpose as queen bees upkeep colonies by laying upwards of 2,000 eggs a day (some rare cases speak of 3,000); drone bees actively seek to mate and pass their genes; and worker bees take care of the hive with responsibilities that evolve with age.

Today, we are going to focus on the life cycle and roles of a queen, worker bee, and drone in a healthy hive (we will save colony collapse scenarios for another day so this article may focus on the specifics of bee life cycles). The queen’s section will be split into four focal elements; the worker bee section will have a day-by-day evolution of responsibilities; and the drone will focus on their singular, significant importance. As a conclusion, we will address how urban beekeeping affects the bees’ lifestyles.

Prelude: Perspective

Over the next couple of minutes, you will get a walk through the life of all three castes of a bee: queen, worker, and drone. To give some perspective on their roles, we will first address their life expectancies.

A drone will live three to five weeks. A worker bee will live five to seven weeks in the summer; a winter worker bee can live up to six months, though (there is a difference in workload and biology). A queen generally lives three to six years.

Headquarters

A queen is the central role of a hive; she is the central signal that a hive revolves around. The queen produces pheromones (chemical substances secreted and detected by smell, in the case of honeybees) encoded with important messages and influences, such as making workers disinterested in mating. Overall, a queen’s pheromones maintain the hive by affecting the behavior of her colony.

Beyond her central signal of control, her primary purpose is to reproduce. The queen is the only bee who will reproduce in normal circumstances (the exception is a laying worker in a colony collapse scenario). To keep up with the needs of the hive, a queen will lay upwards of 2,000 eggs a day! This massive egg output compensates for the six-week life expectancy of a worker bee during the spring and summer months and the massive need for foraging and hive maintenance.

Largely, a queen spends her days solely laying eggs–being the literal life of the hive. Naturally, what comes next is questioning how? So, let’s talk about the nuptial/mating flight.

 

Flight of the Mating Bee

The birds and the bees.

A virgin queen bee will leave a hive for her mating flight as soon as five days after emerging from her cell. On a sunny afternoon with favorable weather conditions, she will then head to a drone congregation area two to three miles away to avoid mating with one of her brothers (drones only travel to local congregations). As she arrives, her pheromonal presence attracts drones hopeful to mate.

The congregation area is up to 650 feet across and 16 to 160 feet high; unlike other bees, honeybees actually do mate in mid air–and at heights higher than their usual flight height. During this mating flight, a virgin queen will mate with up to 50 drones, with a mating average of 12 drones.

A drone inserts its endophallus (genitalia connected to the abdomen) into the queen, with this romantic mating only lasting three to five seconds. After successfully mating, the drone attempts to fly away, but the endophallus remains in the queen; the lower half of the drone’s abdomen consequently is ripped, killing the drone. The endophallus is left behind, left as a “mating sign,” which the next drone will attempt to remove the endophallus to mate with the “virgin” queen.

The queen’s spermatheca stores between five and six million sperm for fertilization usage, taking multiple mating flights to fill such if necessary. The initial mating sperm will be used over the course of her life until a new queen is made to replace her (in which, the new queen may kill or spare the old queen, if she is still alive).

Gender Determination

The queen has complete control over the gender of her eggs. As an egg passes through the ovary to the oviduct, the queen can choose to fertilize the egg with sperm or not. Fertilized eggs become female, worker bees (or queen bees, as discussed in “Royal Reproduction”); unfertilized eggs become male, drone bees.

After the egg is determined, the gender and caste determines its development time table. Drone bees need 24 days to grow from egg to adult; worker bees grow over 21 days; and queens become mature after only 16 days!

Workers bees also have control over the gender of the colony too, though. Workers carry the responsibility of making hive cells, and each kind of bee needs a specific size for its respective egg. Drone bees are much larger than a worker bee, so their egg cells need to accommodate their size; meanwhile, smaller cells are made for worker bees. The queen approaches cells of proper sizes to lay eggs in, therefore the workers influence the gender distribution of the next generation with their work.

The gender distribution becomes a game of balance between the actions of workers and the queen as they work together on the upkeep of the colony. The queen can force the gender she sees fit, and the workers work with her to shape the colony for what’s best for their survival.

Royal Reproduction

Queen bees are an exception when it comes to their birth. The defining differences are that the other castes of bees are born in hive cells, fed royal jelly for the first three days, then fed pollen and nectar for the remainder of their larval state. Queens, on the other hand, grow in queen cells and are only fed royal jelly.

Let’s talk about what these differences imply. Firstly, a queen egg is a female, fertilized egg that is solely fed royal jelly throughout its entire larval state and life, instead of nectar and pollen. Now, what is royal jelly? Royal jelly is a protein-rich excretion from honey bees’ glands–the excretion is akin to milk from a mother, except the substance is more like white snot than milk.

Secondly, the queen cup is designed to raise a queen–either made when a queen bee is nearing her end (end of her life, or end of her reproductive usage) or when a colony becomes queenless. With a cup prepared, an egg will either be laid by a living queen or a fertile egg will be moved into the queen cup. Though, a fertile egg has to be younger than three days old to raise a proper queen.

Why? After three days, fertile larvae are fed the pollen and nectar mixture–which inhibits their ovary (so a queen avoids nectar and pollen like the plague); queens are determined more by the lack of pollen and nectar in their diet than by the pure diet of royal jelly. The queen’s ovary will grow to its limit as it develops in its larval state, and the queen will end up 1.5 the size of the other bee castes.

To touch on the queen cup’s design briefly, the cup will always be built vertically with the opening on the bottom, and the cup is designed to be built upon and lengthened for the queen’s elongated size. The cup is made out of wax that is produced by the honey bees’ wax glands, which the bees develop in the abdomen between 12 and 20 days old.

A Life’s Worker

The survival of a colony rests on the workers (aside from survival relying on a queen’s reproduction). Workers largely nurse the hive and forage for resources, filling key roles with designated tasks that evolve with age. Below, the exact responsibilities will be outlined with the age of a worker that performs the task.

As soon as a worker bee emerges from its larval state, she unconsciously detects the pheromones of the baby bees, and those pheromones kick in the worker’s instincts to nurse their younger sisters.

  • Days 1-2: Worker bees will start off responsible for cleaning the hive cells and keeping the brood warm.
    • All cells are kept clean and sterile before laying eggs or storing honey, and they are responsible for capping the brood cells and securing the larvae. These young bees are responsible for keeping the hive free of disease for the health of the colony.
      • This also includes getting rid of diseased or deceased larvae as quickly as possible, taking the carcass as far away from the hive as possible. In the event of a large carcass (like a rodent) stung to death inside the hive, the worker bees will simply cover the carcass with propolis–a sticky, antimicrobial substance collected from trees.
  • Days 3-5: Worker bees will feed older larvae.
    • Nursing bees will check on their larvae over a thousand times a day!
    • Older larvae, eight days before hatching, will be fed 10,000 times a day to satisfy their hunger and let them grow plump before emergence.
  • Days 6-11: Worker bees will feed younger larvae
    • Habits are similar to their younger nursing sisters feeding older larvae, but the younger larvae are not as hungry.
  • Days 12-17: Worker bees will produce wax, build combs, and transport food within the hive.
    • During this period, workers will develop wax glands (as previously mentioned). They will use these glands to produce beeswax, build combs, and support the hive’s structure. At this age, workers are also responsible for transporting food within the hive to various honey storing locations, organizing what their older sisters forage.
      • A worker has to consume eight kilograms of honey just to produce one kilogram of wax.
  • Days 18-21: Worker bees will guard the hive entrance.
    • At this age, her stinger will fully develop, and her duty shifts to guard the entrance. Guardians detect nearby intruders using their senses, primarily by smell. If an intruder gets too close and poses a threat, the guardians will rush to protect the entrance and sting any threat–doing so, as discussed in the Language of the Bees blog, will release a pheromone to signal the threat to nearby workers.
      • This pheromone signals other guardians to charge towards the target with the aim of stinging it to death; this pheromone alarm is a potent defense as the threat will receive numerous incoming stings, killing the threat if not deterring it first.
    • A worker bee can actually stab other insects or thin-skinned animals multiple times without dying (other bees, wasps, rodents, etc.). However, a bee can only sting an intruding, thick-skinned mammal once, dying as their stinger stays behind.
  • Days 22-End: Worker bees are now classified as field bees, instead of hive bees.
    • These field bees will travel to flowers and perform the key foraging efforts. Field bees are the ones to thank flower pollination; field bees are also the ones to collect pollen, nectar, propolis, and water in key foraging routines.
    • Worker bees have a general life expectancy of six weeks, with the range spreading between 35 and 45 days old.

Winter bees, classified as diutinus bees, are a bit different than their foraging season counterparts, though. As the temperature drops, the queen will halt all reproduction efforts, and the workers’ biology changes with this adjustment. The lack of pheromones from baby bees means a worker’s nursing instincts won’t kick in, so their biology adjusts to a long-living variant; the winter season demands less strain from a worker bee, so their bodies adjust to thrive and care for the queen for the duration of winter.

These diutinus bees will then be the first to fly out and forage as winter thaws, and the cycle starts all over with new six-week patterned bees being laid.

Drone: A Simple Importance

A male drone’s role is much simpler than the worker’s; a drone’s singular purpose is to mate. Only present in the spring and summer, a drone will emerge from his egg and continue to eat three times more than workers as he matures. After a week of maturing, he will start to become sexually active and begin to take flight. His first flights will last only 15 minutes as he simply loops around the hive to become oriented with the hive’s location.

Once oriented, a drone will fly to a drone congregation area on sunny afternoons–with a heavy preference of temperatures above 66 degrees Fahrenheit, no rain, and wind speeds less than 60 miles per hour.

He will spend 30 minutes or more at a time on a mating flight at a drone congregation area with many bachelors like him. If he is lucky and successful in mating with a queen, he will die in the process (see Flight of the Mating Bee), and his genetics will be passed on. If unsuccessful, he will simply keep trying as long as he lives, taking flight multiple times a day for every day he can.

While drones do not perform useful hive labor like their female counterparts (even lacking a stinger for hive defense), drones are considered crucial for the genetic diversity they bring in the mating process. Studies show that a colony’s chances of survival increases with the number of mates the queen had; genetics are the key factors in determining a colony’s size, temperament, and quality. Drones have the key responsibility and purpose to improve the survivability of bees abroad.

Important as they may be, a surplus of drones may stress a colony due to resource consumption–as they continue to consume three times as much as workers throughout their lives–so most hives limit the number of drones at a ratio of one drone for every 100 workers.

As the warmth gives way to sweater weather, any drone still alive will be kicked out of the hive and left to starve as the hive prepares to survive the cold. The hive cannot afford to support a drone’s diet during winter, so this banishment is for the greater survival of the colony. Besides, a drone cannot become diutinus, so he could not live for much longer either way.

Current Day

Urban beekeepers make the best efforts to save the bees while encouraging their natural cycles to remain consistent. Our beekeepers, amongst others, create homes and make space for our buzzing buddies, especially with habitat loss being a major problem. In addition to providing a stable habitat, beekeepers will either create a feeding frame or grow plants to help with foraging efforts so our bees may have proper resources in our urban areas.

Another way urban beekeepers may help out the bees is by queen grafting. A practice we here at Bee Safe use, queen grafting is the technique of building queen cups and placing fertilized eggs inside. The bees are naturally led to build up a queen cell around the cup and properly raise queens. This technique is used to prepare queens in the scenario that a queen may disappear or die for various reasons; this queen grafting provides a saving grace for queenless colonies that would otherwise fall apart. Now, bees can save themselves if they have the resources; but, if they lack young, fertilized eggs, the colony would die off without our intervention.

Truly, not every beekeeper keeps their bees the same–some only check on their hive twice a year to leave the colony’s survival to nature. No matter what though, us beeks are making every effort to save bees out there by making homes in our urbananized world, and we could use your help doing so!

An easy step is to follow us on Instagram, TikTok, Facebook and YouTube @beesafebeeremoval. Every interaction helps get our content out there to actually make a difference. We hope to educate people to make way for truly saving the bees! Though, if you want to do more than interact with our content, feel free to DM us on Instagram or Facebook and ask about what you can do.

Chimney Wasps

August 5, 2021 Wasp Control

Chimney Wasps

Got a wasp problem in your house? Looking to prevent one? Below, we will address a few tips and tricks to rid your house of these garden predators.

Dangers of the Wasp

We don’t deny the benefits a wasp can bring, but a house wasp is, to say, less beneficial…

A nest of wasps inside your chimney can present a stinging hazard and dangerous threat to your family (and pets); the threat is worse if someone has a wasp allergy, as a sting could cause an anaphylactic–severe, potentially fatal–reaction.

Another danger is the nest itself. The nest is made out of paper-like material, and, if that material is in the chimney, you can probably guess what can happen: a chimney fire. So, this paper wasp nest can threaten more than just your family; the chimney nest threatens structural damage.

How to Remove a Nest

If you wish to deal with the wasps yourself, be careful. Take every precaution possible.

Wasps become less active in temperatures lower than 55 degrees Fahrenheit, and they are less active at night and early in the morning. These times are ideal to lessen the danger (though, do not undermine their threat), opening an opportunity to peek into the chimney. Get a powerful flashlight and orient the position of the hive. The hive will more than likely be at the top of your chimney vent.

First of all, if you hear buzzing, the chimney may host a beehive instead of a wasp nest–wasps are much quieter. If you verify they are bees, do not attempt to deal with them. Call Bee Safe Bee Removal to do that job; the hives are difficult to deal with and will attract future problems if not properly removed. If they are wasps (and you are brave), continue on.

You’ll then wear protective clothing. You’ll want at least one extra layer of clothing (extra long-sleeve shirts, pants, and boots are preferred for maximum coverage), plus you will want gloves, safety glasses/goggles, and a mask to protect uncovered areas from wasps and yourself from the spray.

If you’re properly covered, you can take the bold step and go for the hive. You will need a ladder tall enough to access your vent from the outside, unless the hive is near the bottom of the chimney (a rare, unlikely case). Then, thoroughly douse the nest with a strong projectile wasp spray. After application, let them perish for a day then check again. If some are alive, repeat the process until they no longer “pose a problem.”

With the pests disposed of, get a broom or dust stick and get the nest out.

 

 

Call a Professional

Wasps are scary. Trying to deal with them is not for everyone, nor is it wise to (especially if you have allergies, then please don’t).

Give us a call, and let’s just talk and give an estimate. We are certified and will gladly dispose of this threat to you and your family. Wasps are much more aggressive than other stinging insects, and they need to be dealt with immediately to avoid issues.

Why in my Chimney?

To help explain prevention, we must understand why they nested in the chimney to prevent future cases (in and out of the chimney).

Wasps look for secluded places of safety and comfort. Your chimney sounds perfect to the average wasp. The wasps will fly into your vent and build their nest near the entrance, where the exit is close while providing protection.

Prevention

The best method is to get a fireplace vent/mesh screen. Blocking the chimney with any other material renders the fireplace useless, but the mesh screen allows smoke to pass through while filtering out unwanted guests.

There are top-fitting dampers out there that work too. These dampers can be opened and closed. Naturally, you would keep it shut (which also provides insulation) unless you start a fire, in which the smoke would prevent wasps from entering. The damper and mesh screen both fulfill their purpose well with proper usage.

Though, the vent may not be the only entry point. Wasps love the gaps in your chimney. You’ll want to make sure any gaps are sealed with caulk to deny entry.

A final step you can take is to set up a decoy nest. Wasps do not build their own nests within 200 feet of another wasp nest. Setting up decoys around your property simply abuses science and natural tendencies of wasps to shew them away.
