Parasitic fly spotted on honeybees, causes workers to abandon colonies

Parasitic fly spotted on honeybees, causes workers to abandon colonies | Pahndeepah Perceptions | Scoop.it

Throughout North America, honeybees are abandoning their hives. The workers are often found dead, some distance away. Meanwhile, the hives are like honeycombed Marie Celestes, with honey and pollen left uneaten, and larvae still trapped in their chambers.

 

There are many possible causes of this “colony collapse disorder” (CCD). These include various viruses, a single-celled parasite called Nosema apis, a dramatically named mite called Varroa destructor, exposure to pesticides, or a combination of all of the above. Any or all of these factors could explain why the bees die, but why do the workers abandon the hive?

 

Andrew Core from San Francisco State University has a possible answer, and a new suspect for CCD. He has shown that a parasitic fly, usually known for attacking bumblebees, also targets honeybees. The fly, Apocephalus borealis, lays up to a dozen eggs in bee workers. Its grubs eventually eat the bees from the inside-out. And the infected workers, for whatever reason, abandon their hives to die.

 

There are hundreds of species of Apocephalus flies, and they’re best known for decapitating ants from the inside. The larvae, laid within an ant, migrate to the head and devour the tissue inside. The brainless ant wanders aimlessly for weeks, before the larvae release an enzyme that dissolves the connection between the ant’s head and body. The head falls off, and adult flies emerge from it.

 

A. borealis has a similar modus operandi, but it targets bees not ants. Core discovered its penchant for honeybees by sampling workers that had been stranded in the lights of his faculty building, and other locations throughout the San Francisco Bay area. The fly was everywhere. It was parasitizing bees in three-quarters of the places that Core studied, and its DNA confirmed that the species that attacked honeybees was the same one that kills bumblebees.

 

When Core exposed honeybees to the flies in his lab, he saw the same events that befall unfortunate ants. The flies lay eggs in a bee’s body and weeks later, larvae burst out from behind the insect’s head. It’s no surprise that the infected bees, with up to 13 larvae feasting on their brains, seem a little disoriented. They walk round like zombies, pacing in circles and often unable to stand up.

 

They also abandon their hives. Core found that the dying insects literally head towards the light. Large numbers of them become stranded within bright lights. Many flying insects show a similar attraction, but the stranded bees were stock still rather than buzzing about. They would also head towards lights on cold, rainy nights when other insects seek shelter.

Solar power with a view: Transparent luminescent solar concentrators

Solar power with a view: Transparent luminescent solar concentrators | Pahndeepah Perceptions | Scoop.it

Researchers have developed a new type of solar concentrator that when placed over a window creates solar energy while allowing people to actually see through the window. It is called a transparent luminescent solar concentrator and can be used on buildings, cell phones and any other device that has a flat, clear surface."

Russ Roberts's curator insight, August 21, 1:24 PM

The "transparent luminescent solar concentrator" developed by Lunt, an assist The assistant professor of chemical engineering and materials science, can be used on "any flat, clear surface", including buildings, cell phones, and event tablets. The solar harvesting system uses small organic molecules to absorb specific non visible wavelengths of sunlight.  The infrared light is guided to the edge of the plastic material, where it is converted to electricity by thin strips of photovoltaic solar cells.  Lunt says that "Because the materials do not absorb or emit light in the visible spectrum, they work exceptionally transparent to the human eye."  This development could be a game changer for portable power systems, batteries, and emergency power applications.  Keep an eye on this.  Aloha de Russ (KH6JRM).

Fracked on Their Own Petard: The Self-Implosion of an Industry on the Ropes

As Denton seeks to become the first city in Texas to ban fracking, the industry is trying to frame the fight in economic terms. But that turns out to be a poor choice.
Keith Wayne Brown's insight:

Go Adam with  your Op/Ed at Truthout: As the industry clutches at straws - and threatens lawsuits - they are alienating more and more people. At a recent City Council hearing, with 600 people sitting in three overflow rooms, 85 percent of Denton speakers supported the ban. When you've got mothers testifying about how living at home has become a nightmare while industry representatives say we must "fully and effectively" exploit mineral resources no matter what - well, it becomes pretty clear who the real extremists are.

Understanding how networks function isn’t esoteric specialist knowledge anymore than being able to read is."

Keith Wayne Brown's insight:

In states that have already legalized same-sex marriage, we haven’t seen the crumbling of social order that conservatives insists will happen. Far from destroying the family unit and ruining the country, same-sex couples behave a lot like every other couple: They marry, they have families, some they get divorced, others spend their lives together. In fact, there is even some cutting-edge research which suggests that gay couples raise healthier kids than straight couples on average. Whether you subscribe to that theory or not is beside the point, in every example we have (in the United States and abroad), gay marriage has been fine. Conservatives in same-sex legal states may not like it on an ideological level, but I bet they would have a hard time coming up with an example of how their lives have changed in any tangible way since it happened.

Destruction of land and soil by poor farming isn't inevitable.
Keith Wayne Brown's insight:

The perpetual cycle of planting mono-crops, saturating the crops and fields with toxic chemicals, tilling them under and replanting them destroys the soil and degrades the land by depleting soil nutrients and causing erosion. Overgrazing pastures instead of managing livestock herds holistically, using a system of planned rotational grazing, is equally destructive.
