It is propaganda from 1950s (2 years after the communist putsch) so it is pretty loaded against West in general.

* American Colorado Beetle = Mandelinka Bramborová (its common neutral name)

Translation:

Those clouds are not bringing blessing. Those clouds are coming from the west. Together with clouds American imperialists sent American Colorado beetle on our republic.

Father with son has found the American Colorado beetle. This is it! The American Beetle, latest tool of American barbarism. We found it where it does not belong, on the wood instead of potatoes, we found it on the junkyard, American Beetle is climbing wall.

The beetle is spread via wind and planes from our west and south borders. It is spread by secret western agents bringing it in boxes. Those who sent it to us expect that this beetle will find its way to our potatoes. They expect that it will lay thousands of eggs and red-orange larvae will come up.

What is the aim of American imperialists? Their aim is to use the most dangerous potato pest to destroy our advanced potato industry! They want to hamper our nutrition, our livestock farms and industry for whom the potatoes are important resource.

Those bottomless larvae are culture of nuclear warmongers. But our imperialists gentlemen were planning wrong. Or government did decisive measures. Decisive measures to deflect wicked attack of our enemy. But they could have already known that in the West. In our country we do more than we talk. We all and especially youth, pioneers, are getting into a fight. We will find every American Beetle, and destroy it. Every place of its occurrence will get disinfected. Every place of its finding will get properly marked. We will involve technology into fight against the vermin. We are putting all our strength into saving our work. This is our direct defense against attack of our enemies.

We won't let them pupate under the ground. We will find them and we will destroy them. That's our answer to enemy attackers. We got rid of (Milada) Horáková, we got rid (Oldřich) Pecl, we will get rid of American Colorado Beetle, the American Beetle. We will defend our harvest and our fields from American disease. We don't want foreign, but we won't give up ours.
