The plebeian seam bug mainly make it on human blood , but what take place when that human has upped his or her origin alcoholic beverage content with a few glasses of a nice red vino ? New enquiry from the University of Nebraska - Lincoln suggest bed hemipteron are not as fond of alcohol as their sottish hosts , which may lead to few bug bites .
According to the study , bed bugs prefer alcohol - free pedigree to blood withalcoholin it ; the high the blood intoxicant concentration ( BAC ) , the less the bugs use up . And , because there is a direct tie-in between blood inspiration and reproduction charge per unit , those bugs also dwell fewer eggs .

" [ Bed bugs ] need a blood repast to arise and to molt and to procreate , " explain Ralph Narain , a PhD candidate who conducted the work as part of his thesis . " And one of their main hosts are humans , and we consume a mint of stuff . Alcohol was one of the easier one to start with . "
Narain submit the findings last week at the National Conference on Urban Entomology in Atlanta .
How seam bugs imbibe
While it ’s fun to imagine graduate student knocking back beers and feeding seam bugs on their arms , Narain assume a more scientific approach in his experimentation . He mixed 200 proof ethanol — the same compound estimated by a Breathalyzer — into four samples of expired pedigree from the Nebraska Blood Bank until he had BACs of 0.010 , 0.025 , 0.050 and 0.100 ( 0.08 is the effectual limit for drive ) . A control sample contained no intoxicant .
Next , he selected 20 adult seam bugs for each blood sample , weighed them , fed them their respective samples , and weigh them again . He repeated the experiment six time .
The average mass of the layer germ that fed on the clean blood increase by over 100 percent . Those that fed on the ancestry with the lowest BAC , 0.010 , increased just 60 per centum , and the number decreased for each increase in intoxicant . The bottom bugs that fed on the 0.100 BAC sample go up a simple 12.5 percent .
As for the eggs , the control groups lay an average of 44 after the alimentation , while those that fed on the highest BAC laid an average of just 12 .
It ’s unclear whether thealcohol affected the adult bugs’behavior or their materialization ’s growing , although future tests might attempt to measure out both . Narain also plans to run tests on other drug , although he would n’t formally disclose which .
Way toward pest ascendance ?
So , can we just bump back a few glasses of vino every night to keep the bed bug away ? in all likelihood not . " I ’m not going to suggest someone should waste alcoholic drink to master bed bug , " Narain said .
Ill health affects aside , it likely would n’t helpcurb an plague . While the bed bugs do fertilise less on alcohol - laced blood , they still feed , and while they lay fewer egg , up to 95 percent still incubate . And it just takes a few to create a pain .
Dini Miller , an entomologist and bed bug expert from Virginia Tech , harmonize : " I do n’t know what sorting of implication it has in the end , because unluckily they still produce enough eggs to have an infestation . So while they fertilize less , still , we ’re not give out to have less of a problem . But it ’s very interesting to know . "
