本周周四6点,我们全家一起看了关于虫类的《新闻大求真》专期,那――实在是太恶心啦!!!


网上有传言:如果家中发现了一只蟑螂,就说明你家藏了一万只蟑螂。貌似听起来挺吓人的,不过科学嘛,就是需要大无畏的精神从。求真记者在长沙某小区内找到一套合租房,由于人多杂乱,又脏又潮湿,非常合适蟑螂的生存条件,专业人员在厨及卫生间这样潮湿温暖的地方喷满了杀虫剂。三天过去,求真记者满怀激动而紧张的心情,进门一看,大家都吓了一跳,那还是原来的那个厨房吗?满地都是蟑螂的尸体专业人员告诉我们,厨房里的尸体目测的话大概有1000―1500只蟑螂,所以,一般的家住环境不可能有一万只蟑螂。而一只蟑螂背后最多有2个蟑螂窝,因为如果数量太多,就会对雌性蟑螂的生殖产生约束。


节目最后,专家给我们介绍了一个见到蟑螂正确的消灭方法:首先是用纸巾裹住蟑螂,放在一个与生活环境隔离的地方(可以在一个盒子里装上土壤,把蟑螂放进去,用热水浇或者直接用火烧)使其完全摧毁卵巢。不然,如果那是只雌性蟑螂且它体内的卵已经成长到30天了,那就完全可以靠吸收母体残余养料成为个体生物,也就是说,你家里极有可能多出50―70只蟑螂,好怕怕!


以后我们一定要注意卫生,在见到蟑螂时一定要用正确的科学方法应对。

At 6 o'clock on Thursday this week, our family watched the special issue of "seeking truth from the news" about insects. That's really disgusting!!!

There is a rumor on the Internet: if you find a cockroach in your home, it means you have 10000 cockroaches in your home. It may sound scary, but science requires the spirit of fearlessness. Qiuzhen reporter found a shared house in a community in Changsha. Due to the large number of people, messy, dirty and humid, it is very suitable for the living conditions of cockroaches. Professionals sprayed insecticides on wet and warm places like kitchen and toilet. Three days later, the reporter was full of excitement and tension. When he came in, everyone was shocked. Is that the original kitchen? The floor is full of dead cockroaches. Professionals tell us that there are about 1000-1500 cockroaches in the kitchen by visual inspection. Therefore, it is impossible to have 10000 cockroaches in a normal living environment. There are at most two cockroach nests behind a cockroach, because if the number is too large, it will restrict the reproduction of female cockroaches.

At the end of the program, experts introduced to us a correct way to eliminate cockroaches: first, wrap the cockroaches in paper towels and put them in a place isolated from the living environment (you can put soil in a box, put the cockroaches in, water them with hot water or burn them directly) to completely destroy the ovaries. Otherwise, if it's a female cockroach and its eggs have been growing for 30 days, it can become an individual by absorbing the residual nutrients of its mother. That is to say, there are likely to be 50-70 more cockroaches in your family. I'm afraid!

In the future, we must pay attention to hygiene, and use correct scientific methods to deal with cockroaches.
