Biological pest control predatory midge "Feltiella acarisuga", and a ladybird "Stethorus punctillum". The bug "Orius insidiosus" has been successfully used against the two-spotted spider mite and the western flower thrips ("Frankliniella occidentalis"). Predators including "Cactoblastis cactorum" (mentioned above) can also be used to destroy invasive plant species. As another example, the poison hemlock moth ("Agonopterix alstroemeriana)" can be used to control poison hemlock ("Conium maculatum"). During its larval stage, the moth strictly consumes its host plant, poison hemlock, and can exist at hundreds of larvae per individual host plant, destroying large swathes of the hemlock. Not all biological control agents are directed at
Felicia (genus) wait for insects to wander into their grasp. Usually nearly all florets set seed, the involucre will open outward when ripe, and the wind will carry away the easily detaching cypselas, thanks to the hairy pappus. The semi-parasitic plant "Thesium namaquense", also called poison bush, may infect at least two of the species, "F. filifolia" and "F. muricata", and when these "Felicia's" are browsed repeatedly by the same animal, this may cause poisoning, particularly in sheep. Felicia (genus) Felicia is a genus of small shrubs, perennial or annual herbaceous plants, with 85 known species, that is assigned to the daisy
