Stinking passionflower (Passiflora foetida) is a weed of roadsides, disturbed sites, waste areas, watercourses (i.e. riparian habitats), closed forests, open woodlands, plantation crops (e.g. sugarcane) and coastal environments. Passiflora foetida is listed under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) as being amongst the main weed threats to the monsoon vine thickets of the Dampier Peninsula in Western Australia. The weed invades many high value tourism sites across the north of Australia. In Western Australia considerable resources are spent controlling the weed via large scale manual control close to high value tourism assets (e.g. Danggu Geikie Gorge National Park). The visual impact of the weed is high due to tree overtopping and the formation of thick and vast vine mats over the ground and understorey.

Biological control offers a potential as suite of pathogens and insects found to damage the plant severely and because of biocontrol success with vines and lianas previously.
