Definizione

An organism that lives in or on and takes its nourishment from another organism. 1

Nota

Dodder and morning glory are the most recognizable vine parasites. These flowering plants wrap slowly around the stem, trunk or branches of a host plant and leech nutrients. Unlike many root parasites, which injure but rarely kill a plant, vine parasites can become a lethal threat to their hosts, covering the host plant's leaves and preventing photosynthesis from taking place. Vine parasites such as dodder and morning glory do not photosynthesize, but rely on their host for all nutrients. 2

Contesto

The researchers believe that application of the synthetic sex pheromone may reduce the number of female eggs produced, and it might help stimulate the parasites to look for VMB in the vineyard. 3
