Bed bugs can be very unpleasant for humans. Because the small blood-sucking parasites prefer to nest in the bedroom, in order to be able to serve regularly with their host. The astonishing thing: in their hiding places the plague ghosts seem to prefer a new study to certain colors. As US researchers currently report in the journal "Journal of Medical Entomology",Red high in the course, while green the animals rather frightens.
Parasites nest in the vicinity of their host
The so-called "bed bugs"( also called "house bugs") are night-time, non-flightable parasites that feed on the blood of humans. That is why they live where their host regularly stays for a long time: in the bedroom. The most popular place is the bed;also projecting wall corners, skirting boards or light switches ideal hiding places. But do colors play a role? This question was posed by scientists from the USA who came to interesting results in search of possible favorite colors of bedbugs.
The researchers had created small tent-like cardboard hiding-places for the animals and designed them in different colors. The colorful constructs were evenly distributed in Petrischalen and a bug placed in the middle of the shell. The researchers gave the parasites ten minutes to decide for one of the colored hostels. It is found that the insects prefer to look behind red and black. Green and yellow hiding places, on the other hand, were less in demand, according to the scientists from the University of Florida and the Union College in Lincoln.
Bugs look for the proximity of their fellow members
They subsequently varied the experimental setup by, for example, comparing the behavior of female and male animals or that of hungry, oppressed bedbugs. The researchers realized that the color prevails differed in some cases depending on the starting situation and, for example, Individuals other colors preferred than those who were part of a group.
"We first thought the bedbugs might prefer red because blood is red and it is that they feed on," says Dr. Corraine McNeill, according to a press release from the Entomological Society of America."However, after the end of the study, we think they prefer red, because bedbugs themselves appear red. They are looking for these hiding places to be near other bugs as they are known to live in larger collections, "co-author McNeill continues. The fact that yellow and green hiding places are rather avoided is probably due to the similarity to brightly lit areas.
Knowing the favorite colors can be used for new traps
"I've always joked with people,to get yellow bedlakes! '"McNeil continued."But to be honest, I think that would slightly over-extend the results." However, if pheromones or carbon dioxide were combined, the results could well help create better traps. Both of them are attractants for bugs.(nr)
