New research has found that the number of debris in a house or room cannot predict the kinds of insects and other creepy reptiles found there. In a detailed survey of 50 families in Raleigh, North Carolina, entomologists learned that indoor insect diversity is not affected by cleanliness, pesticide use or pet keeping.
We found that as far as residents' behavior is concerned, there is little influence on the distribution of arthropods in the whole family. Michelle Trautwein, co-author of the study and assistant director of entomology at the California Academy of Sciences, said, "The researchers found that,
Carpets, windows and doors are related to more different stroller communities. [Photo: 15 kinds of insects and spiders may live with you]
The paper "Secret Roommate" was published in today's Science Report (165438+1October 10), which is the third group of findings in the analysis of 50 families in North Carolina. Previously, researchers found that the richer the community, the more kinds of indoor insects, which may be because the more luxurious the landscape around the family means that more insects, spiders and millipedes can break in outside. They also found that 73% of indoor insects belong to flies, beetles, wasps, spiders or ants.
The goal of this new study is that Trauttwein told Life Science to create a diversity map of different rooms. For example, it is rumored that there may be many cockroaches in the kitchen and spiders in the basement. Stratwin said, but it turns out that this is only partially correct. There is indeed a unique insect community in the basement, including spiders, camel crickets, millipedes and ground beetles. However, in other parts of the house, there is not much difference between rooms.
Trauttwein said that basements may be different from other parts of the house because they tend to be wetter, have less temperature control and are underground. Upstairs, the researchers found that the rooms on the first floor are more diverse than those on the second or third floor, especially those with many doors and windows on the first floor. The researchers wrote that doors and windows are just a starting point. Many things in your home are outdoor vagrants filtered in from the outside, trout said. The researchers found that the inevitable insect "KDSPs" carpet also contributed to the diversity of arthropods. On average, there are more species in carpeted rooms than in rooms with wooden floors, which may be because carpets can cover live insects and catch dead insects.
Although the characteristics of these buildings are somewhat different from the interior design, the owner's behavior seems to be a kind of washing-human activities seem to say to trout, animals living in one's home, such as
Insects can roam freely outside, so it may be useless to use pesticides.
As for neatness, only cellar spiders (Pholcidae) are related to larger messy areas. The appearance of other arthropods, whether knickknacks, knickknacks or scattered things. "KDSP" and "KDSP" pets are no different, although they are found to have changed the microbial composition of the family. "KDSP" and "KDSP" are indeed an inevitable part of your family's human life. Trauttwein said:
This study did not pay attention to families with infection problems, but just looked like typical families. Trauttwein said that there are 100 species of arthropods in every family on average, and people don't even realize their existence. Carpet beetles, flies, cellar spiders, cobwebs and small mold-eating animals called booklice are found in almost 100% families. How do we build long-term relationships with these species? She said that human beings have been building houses for about 20,000 years, and some of the most common insect species may have evolved into their own homes.
Researchers are sampling houses around the world to compare different locations in Peru, Amazon, Sweden, Japan and Australia.
