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
Bane (plant) Bane (plant) The term bane (from , meaning "thing causing death, poison"), in botany, is an archaic element in the common names of plants known to be toxic or poisonous. In the Middle Ages, several poisonous plants of the genus Aconitum were thought to have or prophylactic qualities, repelling and protecting against that which they were "banes" to (e.g. "Henbane", "Wolfsbane"). There is no single species, genus, or family of poisonous plant exclusively referred to as "banes". Several unrelated plants bear the name. In medieval Europe, the toxic entheogen Aconitine was believed to prevent werewolves from undergoing their dire transformations.
