A cockroach is a large insect that you will often find in warm, humid places.

一种大型昆虫，你经常会在温暖潮湿的地发现它们。

I'm wondering about the Oriental cockroach, which also, I'm not sure nomenclature, it seems outdated.

我在想一，不过我不确定这个命名否已经过时了。

So the so-called Oriental cockroach or Blatta orientalis comes from the word for Eastern roach.

因此，所谓的（Blatta orientalis）这个名字来源于“蟑螂”的意思。

Yeah, so they're called appropriately Blattobacterium, cockroach bacterium.

的，它们被恰当地称为菌，即蟑螂细菌。

And as we covered last week with Dr. Dominic Evangelista in the Blattodiology episode, there are 7,000 identified species of cockroach.

正如我们上周在《学》一集中与多米尼克·伊万杰利斯塔博士讨论过的，目前已确认的蟑螂物种有7000种。
