Bacteria are unicellular rod-like organisms that move actively in the water with the help of flagella. Reproduction is done by division and only takes a few minutes in a humid and warm environment. Bacteria are not able to infest a healthy plant surface, they always need open parts such as wounds or gaps. Most bacteria reach their optimum in high temperatures between 25°C and 30°C and high humidity, so repeated explosion-like infestation usually has to be expected during the summer. But even in the darker and cooler seasons they can cause severe damage to orchids, even if the pest develops considerably slower.
