American scientists tried to find out, there are any bed bugs in color, and does color tissue role in the selection of parasites of shelters. The results of experiments, the researchers told the journal Journal of Medical Entomology.
Scientists were placed in Petri dishes "refuge" for bugs, made of colored cardboard. Insects were given ten minutes to choose one of the "houses". In addition, in the course of the experiment changed the gender and age of bedbugs, put in Petri dishes and fed the hungry parasites, groups, and individuals.
It was found that bed bugs prefer black and red and green and yellow trying to avoid. Color was an important criterion in choosing the seekers. "At first we thought that the attachment to the red caused by red blood, which bugs feed. However, according to the research results we can say that the reason is different: the bugs themselves seem red, and in asylum of the respective color they run to find relatives", — said one of the authors of the article Corran McNeal (Corraine McNeill).
The choice of color is determined, and many other factors, scientists say. Preferences of insects change with age, unlike the proximity of other individuals and the degree of satiety. However, dislike for yellow and green all the parasites is that these colors resemble brightly lit areas.
Researchers warn that those suffering from attacks of bugs should not immediately throw out the red and black sheets and buy yellow and green. "The choice of colors does not in itself put a barrier in the way of parasites. Only in combination with other agents against harmful insects," concludes McNeil.
Centre for consumer protection (cspp) and the Ministry of education and science encourage future students to check whether the University has a license for training and accreditation, a spokesman for cspp Sanita Gertmane.
