Remote Control Cockroaches

Remote Control Cockroaches

Researchers from Case Western Reserve University have discovered that understanding the neurons in a cockroache’s brain that make it walk may help scientists improve remote-control technology. By stimulating each neuron separately, scientists can make cockroaches walk according to which neuron they are stimulating. The central complex of a cockroache’s brain controls their movement, acting a bit like a joystick. This joystick controls the insect’s speed and direction. This may help us design more accurate control in our own remote-control technology.

Researchers were able to control the movements of the cockroaches without providing visual stimuli by sending electrodes through the central complex. Even in cases of complex movements such as turning, researchers were able to control the insect’s movement by stimulating their neurons. Researchers think that this descending motor control works the same in all mammals. So, researchers can understand movement in complex animals other than insects through this study. This could extend to helping the handicapped walk, building better robots, and making better self-driving cars and drones.

What do you think of the implications of this study? What do you think the biggest benefit would be?

How cockroaches are different than humans

How cockroaches are different than humans

There are many ways of course that cockroaches are different than humans, but mostly lets discuss bodies. For instance why do cockroaches die on their backs with their legs in the air?

To know the answer to this question is simply to look at them. Cockroaches have rounded backs that are greasy, with a body that is able to be flat. That flat body is what allows them to squeeze in through the cracks in your walls. Commonly used insecticides induce muscle spasms and can confuse the cockroaches, which of course makes them look like a turtle stuck on their back.

Their body oddities are also what allows them to walk up walls whereas of course we humans cannot. Cockroaches have three sets of legs which allow them the ability to go places and do things we can’t like walking up a wall or across glass without slipping.  Each set of these legs is controlled by their own nerves with a foot like claw at the bottom of the leg. There is no central nervous system like and brain in a human. Cockroaches can live without its head because there literally is no brain in there. If left in the wild, cockroaches typically will stick in groups of up to 50 to try to secure safety.

Rapidly Evolving Roaches Just Say No To Sugar

Within a few years, roaches have evolved to avoid sugar.  Remarkably, their adaptation is a result of sugar-laced traps. Unlike humans, they don’t have to use willpower.  Instead, roaches have a built-in aversion based on taste:  sugary flavor comes across as bitter.

Roaches in a recent studied were sampled from colonies in the U.S, Puerto Rico, South Korea and Russia. Among the 19 populations examined, seven included roaches with the sugar-aversive behavior.

Researcher Coby Schal of North Carolina State University noted that the evolution came about “incredibly fast” but also pointed out that some bacteria evolve even more quickly.

In a simple experimental design, researchers filmed roaches to understand their behavior.  The study videotaped groups of roaches as they chose between two food sources.  The bugs were given a choice of a glucose or fructose based jelly, and later, peanut butter or jelly, and observed as they made their choice.

The phenomenon of glucose aversion has been for known some time in the extermination industry, and profession pest-control companies have switched to new types of bait, either high carbohydrate or high protein.

This latest research demonstrates just how well cockroaches learn, and how exceptionally adaptable they are to a variety of challenges.

Roach Personalities | South Florida Cockroach Control

7987321_sResearchers in Belgium have discovered that cockroaches have personalities. At the Universite Libre de Bruxelles scientists tested the behavior of the American cockroach by strapping microchips on 300 roaches and placed them in an arena of bright light. Because cockroaches have developed an aversion to light, they were observed in order to see how quickly they sought shelter. Roaches that immediately went under the cover of a dark circle were considered cautious, while the ones that explored the arena were considered to be more daring.

Scientists also observed the cockroaches to see how they sought shelter. If all cockroaches had the same undifferentiated personality then they would exhibit identical behavior. Researcher Isaac Planas-Sitja reported that the cockroaches’ “amazing ability to reach a consensus could be explained by the bugs affinity for protection of the group. The cockroaches that sought shelter sooner could have been signaling to others what to do,” he said.

Continued collaboration and research could explain the cockroaches’ apparent inability to die out. Some explore the group’s surroundings while others hang back to see if it’s safe. Further research could also explain how so many roaches can invade a cramped New York City apartment at once. Cockroaches have no queen or solitary leader. This, in turn, suggests they have no followers either. They are individuals able to make their own decisions just like us.
This research has uncovered, once again, what extraordinary insects cockroaches are. Cockroaches are very resilient and exhibit odd behaviors and survival methods. For example, cockroaches spend 75% of their time resting and can withstand temperatures as cold as 32 degrees Fahrenheit. A cockroach can live for a week without its head. Because of an open circulatory system and the fact that they breathe through holes in each of their body segments, they do not need a mouth or head to breathe.  Most cockroaches can hold their breath for 40 minutes. They can survive being submerged for half an hour. A cockroach can run up to three miles in an hour, which means spreading germs and bacteria throughout a home can happen quickly.

Top 5 Ways to Rid Your Home of Roaches

Top 5 Ways to Rid Your Home of RoachesResearchers recently found that there is a species of cockroach that survived by eating dinosaur waste. Other research shows that there is an evolutionary ancestor to the cockroach that crawled the earth millions of years before the dinosaurs showed up. It’s no wonder that we believe they will live forever and survive the nuclear apocalypse/holocaust situation people think is coming. If they’ve lived through all of the rest of evolution, surely they’ll outlive us, right?

While we marvel at how survival-capable cockroaches seem to be, that does not mean we welcome their presence in our homes. In fact, catching a glimpse of even a single cockroach is enough to send most people into fumigation frenzy. Luckily you don’t necessarily have to go that route. In fact, there are several things that you can do to keep those bugs from setting up camp in the first place. Here are just a few of them.

Hiring Help

Hiring a roach control expert is something that helps you both get rid of the cockroaches you have already and prevent new pests from invading. Regular spraying (with environmentally responsible sprays and products of course) can keep your house completely roach free.

If the problem is particularly bad (for example, if there is work being done on nearby buildings or constructions sites), you’ll want to hire an extermination expert to really go to town on your home and its foundation. It might take a while for them to be able to fit you in, though; so, while you wait, here are a few things you can do.

Clean It Up

Cockroaches are attracted to warm and dry places that they can burrow into. Piles of newspapers, mail or magazines are a perfect roach hut. Clutter also provides a desirable shelter and, depending upon where it is located, a source of food. Scrub your house from top to bottom. Get rid of the piles of clutter. Put everything away. Invest in some air-tight sealable containers for food and cooking ingredients. It won’t get rid of them completely but it will discourage new roaches from invading when they find that there are very few places to hide.

Borax

Most exterminators will recommend mixing some borax with sugar and sprinkling it around. The sugar attracts the roaches. The Borax acts as a toxin and dehydrates the roach’s exoskeleton. Borax is a fairly harmless product but if you’re worried about your kids’ and pets’ exposure to it, limit the sprinkling of it to your upper cabinets and in higher places.

Note: Do NOT use this mixture near anything that has to do with food (food prep spaces, pantries, dishes).

Fabric Softener

Cockroaches do not like fabric softener. You can test this out by laying a sheet out and watching how a cockroach reacts when an encounter takes place. If the problem in your house is really bad, you can get in some “target practice” by filling a spray bottle with a couple parts of liquid natural/organic fabric softener and water. Spray the roaches when you see them. Enjoy their immediate demise.

Catnip

Catnip is also a natural roach repellant. Sprinkle it around under your sink and in your cabinets and close to your doors. You might even consider sprinkling it around outside. The great thing about catnip is that it is harmless for pets and your kids so you don’t have to worry about vigilantly watching every leaf in the house.

Remember, if the cockroach population grows to problematic proportions, the best thing to do is to hire a professional to help you get rid of them. In the in-between though, using these natural and environmentally responsible roach repelling methods can help out quite a lot.

Roaches Increases Risk for Allergies & Asthma Attacks

Most people think of pollen, dust and animal dander as common asthma and allergy triggers. However, Hulett Environmental, a pest management company servicing South Florida, warns that cockroaches can also pose a threat to allergy and asthma sufferers. The threat for cockroach allergens is elevated in the winter because there a greater chance for cockroaches to invade homes in search of warmth and because families spend more time inside.

Roaches

Children are the most at risk to be affected by this often-overlooked asthma trigger. Cockroaches spread over 33 types of bacteria, including E. coli, and studies show that about one in five children in the U.S. are sensitive to cockroach allergens.”

Huett Environmental Services advises homeowners to seal cracks around the outside of their home, keep counters and floors clean and free of crumbs that can attract the pests and vacuum frequently. Kitchens and bathrooms are particularly vulnerable to cockroach infestations due to the presence of food products and moisture around sinks or appliances.

If you suspect you have an infestation, contact a licensed pest professional who will be able to recommend a course of treatment. To learn more about cockroaches and the health threats they pose, visit Roaches
