According to the work in the Journal of Medical Entomology, the blood-sucking insects love black and red but hate yellow and green. This information could help make better traps to lure and catch the bugs.
根據(jù)《醫(yī)學(xué)昆蟲學(xué)雜志》中的一篇報告指出，吸血的昆蟲都喜歡黑色和紅色，但是討厭黃色和綠色。這個信息能幫助人們做出更好的誘捕并抓住蟲子。
But it is too soon to say if yellow sheets can stop them nesting in your bed, say the US researchers.
但是日前來自美國的研究人員表示，要說黃色的床單能讓他們不在你的床上滋生為時過早。
Bed bugs are tiny and they like to live close to their next meal - your blood. They can hide in the seam of your mattress or a joint in your bed frame. They tend to prefer fabric and wood over plastic and metal.
床蟲體型很小，他們喜歡生活在他們的食物--也就是你的血--的附近。他們會藏在床墊縫里或者你床架的連接處。比起塑料和金屬，他們更青睞織物和木頭。
But Dr Corraine McNeill and colleagues wanted to find out if colors affected where bed bugs might dwell.
科瑞恩·麥克尼爾博士和他的同事們想要研究出顏色會不會對床蟲在哪里生活產(chǎn)生影響。
They carried out a series of experiments in their lab, placing bed bugs in dishes with different color shelters made out of card. Rather than taking cover at random, the bugs appeared to select the shelters according to their color, showing a preference for black and red.
他們在實驗室里做了一系列實驗，把床蟲放在培養(yǎng)皿中，再放入不同顏色的卡片做成的盒子中。實驗結(jié)果顯示，床蟲們并沒有隨機選擇，它們看起來更樂意根據(jù)顏色來選擇居所，并表現(xiàn)出對黑色和紅色的特別喜愛。
Dr McNeill said: "We originally thought the bed bugs might prefer red because blood is red and that's what they feed on. However, after doing the study, the main reason we think they preferred red colors is because bed bug themselves appear red, so they go to these harborages because they want to be with other bed bugs."
麥克尼爾博士表示：“我們一開始認(rèn)為。床蟲可能更喜歡紅色是因為血是紅色的，而它們吸血為生。然而，在做了研究之后，我們認(rèn)為，它們更喜歡紅色的主要原因是因為床蟲自己是紅色的，因此它們?nèi)ミ@些紅色的地方是想跟其他床蟲在一起。”
The bugs appeared to dislike yellow and green shelters, possibly because these bright colors remind them of brightly lit areas that are less safe to hide in, say the researchers.
研究人員還表示，床蟲們看起來不喜歡黃色和綠色的住處，這可能是因為這些亮色會讓它們覺得是躲在不安全的、光線直射的地方。
Dr McNeill said: "I always joke with people, 'Make sure you get yellow sheets!' But to be very honest, I think that would be stretching the results a little too much. I don't know how far I would go to say don't get a red suitcase or red sheets, but the research hasn't been done yet, so we can't really rule that out completely."
麥克尼爾博士對此表示：“我總是和人們開玩笑說，'一定要用黃色床單哦！'但是事實上，我認(rèn)為目前的研究結(jié)果還沒意味著這么做就一定可以不遭受蟲害。我不知道我還需要多久才能告訴人們不要買紅色的提箱或者紅色的床單，研究還沒做完，因此我們不能完全排除任何可能性。”
