Kostrou článku je příběh člověkem způsobené rostlinné invaze, která propukla naplno po téměř 150 letech od vnesení invazního organismu, opuncie Opuntia stricta, do jeho nového teritoria – Austrálie. Na pozadí úsilí biologů i australského státu o eradikaci opuncie se seznámíme se základy biologie CAM rostlin v souvislosti s motýlem Cactoblastis cactorum, jehož housenky se opuncií živí, a se senzory motýla pro oxid uhličitý přijímaný rostlinou skrz průduchy.

This article focuses on the case of a man-made plant invasion that erupted in full almost 150 years after the invasion of the Erect Prickly Pear (Opuntia stricta) of Australia's new territory. Behind the efforts of biologists and the Australian state to eradicate prickly pear, we will learn the basics of CAM plant (with Crassulacean Acid Metabolism) biology in connection with the prickly pear herbivore Cactoblastis cactorum butterfly (its caterpillars feed on O. stricta) and its sensors for carbon dioxide taken by plants through stomata.
