Honeybees (pictured) and wasps will only sting when they feel threatened. They are social animals and often their attacks are as a response to a particular chemical given off by other members of their hiveMost of the 20,000 species of wasps are solitary, but because solitary wasps do not sting, most humans are more familiar with social wasps, who live in complex communities.
Only female bees and wasps can sting. Males do not have the egg-laying organ that is modified into a stinger on female insects.Unlike bees, female wasps have the ability to sting a target multiple times because their stinger does not fall off after use.Social wasps and honeybees both use pheromones, secreted or excreted chemicals that trigger a social response in members of the same species. In social bees and wasps, pheromones act as an alarm. They are secreted by some of the group when they think they are in danger, like if the nest is disturbed or one of them is killed. The rest of the wasps react to the pheromones by swarming out of the nest and attacking the intruderWhen a wasp stings a human approaching a nest, the small insect simultaneously emits a chemical that signals the rest of the colony to attack.This phenomenon was explained in a video from Reactions, a YouTube series from the American Chemical Society that 'uncovers the chemistry in every day life'.'It's not so much that you've killed a wasp, it's that you've threatened a wasp or their wasp home,' says Sophia Cai, host of the video.
Wasps and bees will not sting someone at rest if they have not been disturbed by some agitation of their nest or threatened by swatting or quick movement of arms or legs.They may land on someone's skin to inspect a smell or get water, but they will leave if the person stays calm and does not move quickly. Social wasps and honeybees (pictured) both use pheromones, secreted or excreted chemicals that trigger a social response in members of the same species. When a wasp stings a human approaching a nest, the small insect simultaneously emits a chemical that signals the rest of the colony to attack In honeybees, one of the molecules in their pheromone mix is isopentyl acetate or banana oilCertain insects and animals release pheromones, often as oils or sweat, and other creatures can detect and respond to these compounds. This allows for a form of silent, purely chemical communication.Since pheromones were first defined in 1959, scientists have found many examples of pheromonal communication.
The most striking of these signals elicits an immediate behavioural response. For example, the female silk moth releases a trail of the molecule bombykol, which consistently draws in males from the moment they encounter it.Slower-acting pheromones can affect the recipient’s reproductive physiology, like in mice, when the alpha-farnesene molecule in male’s urine accelerates puberty in young females.In honey bees, one of the molecules in their pheromone mixture is isopentyl acetate, which is also known as banana oil because it is made naturally by the banana plant.

In social bees and wasps, pheromones act as an alarm, secreted by some of the group when they think they are in danger'Both social wasps and honeybees use alarm pheromones to warn their buddies about nearby dangers,' says Ms Cai.These chemicals are secreted by some of the group when they think they are in danger, like if the nest is disturbed or one of them is killed.'If a hive or nest is disturbed, guard wasps will send out these guard molecules to rally the troops,' she says.The rest of the wasps react to the pheromones by swarming out of the nest and attacking the intruder. In honey bees, one of the molecules in their pheromone mixture is isopentyl acetate, which is also known as banana oil because it is made naturally by the banana plant.The molecule is often used to produce a banana flavour in foods because it smells like the fruit.This is why beekeepers will say that a hive of distressed bees smells like bananas.Because the attacks are triggered by pheromones, beekeepers use smoke from a special dispenser to disguise the smell of the molecules and calm their hives down.

Testimony Monday evening related to the incident Friday afternoon dominated the two-hour public forum during the City Council meeting. During the confrontation, a large and angry crowd screamed obscenities and taunted police officers as they struggled to take into custody Jeffrey D. Walton, 29, who police said resisted arrest following an alleged drug transaction. Two videos of the incident show several police officers struggling with Walton at the front of the police car and then pinning him to the ground while using pepper spray, punching and tasing him several times. Several speakers faulted officers for using excessive force and failing to communicate with the crowd to de-escalate the situation. “I’m pretty sure it’s not legal to punch someone in the kidneys,” said Eugene resident Gwendolyn Iris, who helped organize a “speak out against police brutality” that drew only a few people holding signs along Eighth Avenue prior to the meeting.
“I’m pretty sure many of those things I witnessed on that video are not legal, whether you are a police officer or not.” However, Eugene resident Eimar Boesjes praised the “incredibly courageous” policewoman shown in the video who remained composed and held her ground despite taunting from some in the crowd. “I have an enormous respect for someone like that,” he said. “I don’t think I could do it.” Others urged the City Council to do what’s needed to restore order downtown. Eugene resident Thomas Pettus-Czar criticized city councilors for their inaction and said it could have tragic results. “We’re going to continue to see more of what we did last Friday at an escalating scale,” he said. “I feel something really terrible is going to happen; that someone is going to lose their life in a tragic way before anything is actually done.” Eugene resident Caroline Cummings shared her disgust at being sexually harassed by loiterers downtown several times and questioned why they should have more rights than she has.
“It’s your job to take a long, hard look at this and decide if the downtown truly is for everyone, then why is it that I and those I previously mentioned don’t feel safe or welcome there,” she said. Eugene Police Chief Pete Kerns told councilors earlier that officials are working on a two-pronged plan to end the drug use and sales that long have plagued the park, located downtown at Eighth Avenue and Oak Street. The approach is two-fold, he said, featuring a police presence with “some level of enforcement” and introducing an activity “that is healthier, that attracts a broader group of people to the park.” City councilors will learn more about available options and details during a meeting next month. Meanwhile, Police Auditor Mark Gissiner said Monday his office his reviewing the incident and planned to look at the video from the body cameras worn by some of the officers at the scene. Any allegation of excessive use of force by one or more officers brought by his office after the review would trigger a formal internal investigation, Gissiner said.
He declined comment when asked about his initial impressions of the incident. “I don’t have enough information at this point,” he said. During the late summer, the police department stepped up enforcement in the downtown core to crack down on what the police chief and others said at the time was a significant increase in criminal conduct and aggressive behavior by people who loiter in the area. The stepped-up presence, known as “hot spot enforcement,” temporarily tasked two more police officers to walk the area and supplement the assigned downtown patrol. It also directed that other on-duty patrol officers spend as much time on foot when they are not responding to calls on their assigned beats in other parts of the city. The “hot spot” enforcement ended at the end of last month, but the police department has been keeping a close eye on drug activity at Park Blocks since then. The incident began when Eugene police arrested two people for a drug sale about 3:30 p.m. Friday.
Police said the first man was cited and released, but Walton resisted. Eugene police Lt. Doug Mozan, who reviewed some of the video of the incident and read police reports, told The Register-Guard on Saturday that Walton was hanging on to the front bumper of the police car with “enough strength and ferocity” that officers weren’t able to wrest his arm away and had to gradually escalate their use of force so he could be taken into custody. “What finally got him was a culmination of six officers who worked for six minutes to get this guy under control,” Mozan said. Kern, who in an earlier statement praised the officers’ composure and professionalism during the incident, told city councilors the level of force the officers used against Walton was not out of line. “The use of force techniques I watched them use are the type of things we teach our officers to do,” he said. But the escalating use of force angered the crowd of onlookers, which police initially estimated at between 50 to 75 people and then revised down to between 30 and 50 people.
