Where ever you live in the world you should apply the information on working your bees that is given below when the weather conditions in your area are right. So take notes and be ready.

Cletus Notes 

Hello Everyone,

Here in Bryan, Texas as well as most of Texas, the temperatures normally soar into the triple digits in August and September. Our bees work feverously to keep their hive cooled down. There should be a good water source close by for the bees to collect water (preferably not the neighbors swimming pool.) and take it back to the hive where it is stored inside the uncapped cells. The house bees stand close to these water filled cells and fan their wings. The air movement will evaporate the water which will in turn help cool down the inside of the hive.

In some areas around the state, the aster and goldenrod plants are beginning to bloom and the bees have an opportunity to collect nectar from them that will be stored for their winter food source. Sometimes there will be enough nectar coming in for the beekeeper to add a honey super or two and make a surplus.

Here at Lone Star Farms September is usually a slow work month because we rarely ever place honey supers on our hives for the fall flow. We believe that it is better to leave the fall flow for the bees. We run each hive in two brood boxes and allow the bees to fill both their boxes with the fall nectar. That is one reason we don’t have to feed our bees very often. Remember, honey is much healthier for the bees than sugar water. Besides, the bees have already provided us with a good early spring and early summer surplus.

If you take care of your bees first, they will take care of you. Enjoy your bees.

Why 'Whispers' Among Bees Sometimes Evolve Into 'Shouts'

Let's say you're a bee and you've spotted a new and particularly lucrative source of nectar and pollen. What's the best way to communicate the location of this prize cache of food to the rest of your nestmates without revealing it to competitors, or "eavesdropping" spies, outside of the colony?

Many animals are thought to deter eavesdroppers by making their signals revealing the location or quality of resources less conspicuous to outsiders. In essence, they've evolved "whispers" in their signals to counter eavesdropping.

But some species of bees in Brazil do the exact opposite. "Shouts" in their food-recruitment signals warn would-be competitors that their prime source of food will be fiercely defended if they show up to the site. It's a communication strategy that's bold and risky, yet remarkably successful in warding off competitors, according to a paper published in the July 7 issue of the journal Current Biology.

"It's a signal with honest aspects and the possibility of lies," explains James Nieh, a professor of biology at UC San Diego who oversaw the research study conducted in Brazil by Elinor Lichtenberg, a PhD student in his laboratory who is now a postdoctoral researcher at Washington State University. "It tells nestmates where to find good food and hints at a larger occupying force."

Lichtenberg says her discovery of this counterintuitive method of communication by bees suggests that eavesdroppers can alter the evolution of animal signals in ways that were previously not thought possible.

"Our study provides a new way of looking at how eavesdroppers affect the evolution of animal communication signals," she adds. "Until now, it was thought that eavesdroppers select against conspicuous signals, for example by more easily finding and eating prey that sings loudly. But our results show that eavesdroppers can help select for the same conspicuous signals that are easiest for intended recipients to detect and understand."

 To Nieh, whose research has focused on the evolution of communication strategies among bees, "eavesdropping is part of the information web, the signals and cues that surround animals and play a key role in shaping ecosystems."

In the case of bees and other pollinators, he says, "a network of signals and cues shapes pollination, informing animals about where and when food is available. Researchers have in general thought about eavesdropping as a force that makes signals less conspicuous, leading to the evolution of 'whispers' to counter spying. However, we show that eavesdropping can also lead to 'shouts.' In this stingless bee system, with aggressive colonies jockeying for limited resources, more conspicuous food-recruitment signals indicate a higher likelihood that a resource will be harder to wrest away."

Lichtenberg's study focused on stingless bees—including two from the genus Trigona that recruit nestmates to food sources with chemically distinct pheromones—that compete with one another for similar food sources. Trigona hyalinata spies that detect food sources marked by Trigona spinipes foragers will often displace T. spinipes from desirable sites in the wild if they can recruit sufficient nestmates. But Lichtenberg found in a controlled field study that the eavesdropping species will avoid desirable sources of food that have been visited frequently by T. spinipes (communicated by the larger number of pheromone markings at the site) to avoid being attacked. However, T. hyalinata foragers are attracted to food sources with fewer T. spinipes foragers.

The eavesdroppers could take over the highly visited sites by recruiting more of their nestmates or battling with T. spinipes bees, which show high levels of aggression toward intruders, but the risks and energy costs to the eavesdroppers apparently aren't worth the trouble.

The researchers supported this hypothesis by modeling eavesdropping bees' decision-making, using a type of model from economics. They ran the model for T. hyalinata eavesdropping on T. spinipesT. spinipes on T. hyalinata, and the non-aggressive Melipona rufiventris on T. spinipes. In all three cases, they found that the model results matched eavesdropping behavior measured in this study and in previous work by Lichtenberg, Nieh and colleagues.

"Assembling such a group in the nest after having found a food source through eavesdropping uses time and energy the eavesdropper could otherwise spend looking for an unoccupied food source," explains Lichtenberg. "If the eavesdropper brings too small a group to an occupied food source and cannot win access to it, she and the bees accompanying her have essentially wasted energy. For attacks between colonies of the same species, there is also a risk that the conflict will escalate to physical interactions in which large numbers of bees may die."

"Our study is one of the first to investigate what drives the behavior of eavesdroppers collecting information from competitors within the same trophic level, which use the same food resources as the eavesdropper," she adds. "Previous eavesdropping research has mainly focused on individuals seeking mates, predators looking for prey or prey trying to avoid being eaten. In those cases, eavesdroppers' expected behavior is clear. This is not true for eavesdropping on competitors."

The study not only provides information about the evolution of different strategies of animal communication, but suggests how these strategies can affect the ecology of plant communities. "Such strategies affect not only the individuals directly involved, but also broader ecological interactions between the food-gatherers and their food," Lichtenberg says. "This is particularly important for animals such as the bees I studied, because their movements determine plant pollination."

                                                                                      Corn & Soy Neonicotinoids Found Widespread in Midwest Rivers -- USGS News  

Insecticides similar to nicotine, known as neonicotinoids, were found commonly in streams throughout the Midwest, according to a new USGS study. This is the first broad-scale investigation of neonicotinoid insecticides in the Midwestern United States and one of the first conducted within the United States.

Effective in killing a broad range of insect pests, use of neonicotinoid insecticides has dramatically increased over the last decade across the United States, particularly in the Midwest. The use of clothianidin, one of the chemicals studied, on corn in Iowa alone has almost doubled between 2011 and 2013.

"Neonicotinoid insecticides are receiving increased attention by scientists as we explore the possible links between pesticides, nutrition, infectious disease, and other stress factors in the environment possibly associated with honeybee dieoffs." said USGS scientist Kathryn Kuivila, the research team leader.

Neonicotinoid insecticides dissolve easily in water, but do not break down quickly in the environment. This means they are likely to be transported away in runoff from the fields where they were first applied to nearby surface water and groundwater bodies.

In all, nine rivers and streams, including the Mississippi and Missouri Rivers, were included in the study. The rivers studied drain most of Iowa, and parts of Minnesota, Montana, Nebraska, North Dakota, South Dakota, and Wisconsin. These states have the highest use of neonicotinoid insecticides in the Nation, and the chemicals were found in all nine rivers and streams.

Of the three most often found chemicals, clothianidin was the most commonly detected, showing up in 75 percent of the sites and at the highest concentration. Thiamethoxam was found at 47 percent of the sites, and imidacloprid was found at 23 percent. Two, acetamiprid and dinotefuran, were only found once, and the sixth, thiacloprid, was never detected.

Instead of being sprayed on growing or full-grown crops, neonicotinoids can be applied to the seed before planting. The use of treated seeds in the United States has increased to the point where most corn and soybeans planted in the United States have a seed treatment (i.e., coating), many of which include neonicotinoid insecticides.

"We noticed higher levels of these insecticides after rain storms during crop planting, which is similar to the spring flushing of herbicides that has been documented in Midwestern U.S. rivers and streams," said USGS scientist Michelle Hladick, the report's lead author. "In fact, the insecticides also were detected prior to their first use during the growing season, which indicates that they can persist from applications in prior years."

One of the chemicals, imidacloprid, is known to be toxic to aquatic organisms at 10-100 nanograms per liter if the aquatic organisms are exposed to it for an extended period of time. Clothianidin and thiamethoxam behave similarly to imidacloprid, and are therefore anticipated to have similar effect levels. Maximum concentrations of clothianidin, thiamethoxam and imidacloprid measured in this study were 257, 185, and 42.7 nanograms per liter, respectively.

The U.S. Environmental Protection Agency has classified all detected neonicotinoids as not likely to be carcinogenic to humans.

                                                                                                            Scientists Track Gene Activity When Honey Bees Do and Don't Eat Honey

CHAMPAIGN, Ill. — Many beekeepers feed their honey bees sucrose or high-fructose corn syrup when times are lean inside the hive. This practice has come under scrutiny, however, in response to colony collapse disorder, the massive -- and as yet not fully explained -- annual die-off of honey bees in the U.S. and Europe. Some suspect that inadequate nutrition plays a role in honey bee declines.

In a new study, described in Scientific Reports, researchers took a broad look at changes in gene activity in response to diet in the Western honey bee (Apis mellifera), and found significant differences occur depending on what the bees eat.

The researchers looked specifically at an energy storage tissue in bees called the fat body, which functions like the liver and fat tissues in humans and other vertebrates.

"We figured that the fat body might be a particularly revealing tissue to examine, and it did turn out to be the case," said University of Illinois 
entomology professor and Institute for Institute for Genomic Biologydirector Gene Robinson, who performed the new analysis together with entomology graduate student Marsha Wheeler.

The researchers limited their analysis to foraging bees, which are older, have a higher metabolic rate and less energy reserves (in the form of lipids stored in the fat body) than their hive-bound nest mates -- making the foragers much more dependent on a carbohydrate-rich diet, Robinson said.

"We reasoned that the foragers might be more sensitive to the effects of different carbohydrate sources," he said.

The researchers focused on gene activity in response to feeding with honey, high-fructose corn syrup (HFCS), or sucrose. They found that those bees fed honey had a very different profile of gene activity in the fat body than those relying on HFCS or sucrose. Hundreds of genes showed differences in activity in honey bees consuming honey compared with those fed HFCS or sucrose. These differences remained even in an experimental hive that the researchers discovered was infected with deformed wing virus, one of the many maladies that afflict honey bees around the world.

"Our results parallel suggestive findings in humans," Robinson said. "It seems that in both bees and humans, sugar is not sugar -- different carbohydrate sources can act differently in the body."

Some of the genes that were activated differently in the honey-eating bees have been linked to protein metabolism, brain-signaling and immune defense. The latter finding supports a 
2013 study led by U. of I. entomology professor and department head May Berenbaum, who reported that some substances in honey increase the activity of genes that help the bees break down potentially toxic substances such as pesticides.

"Our results further show honey induces gene expression changes on a more global scale, and it now becomes important to investigate whether these changes can affect bee health," Robinson said.
