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
Beta (plant) with the highest economical value in the order Caryophyllales. Therefore, the members of "Beta" and the related genus "Patellifolia" are interesting as Crop wild relatives. Beta (plant) Beta is a genus in the flowering plant family Amaranthaceae. The best known member is the common beet, "Beta vulgaris", but several other species are recognised. Almost all have common names containing the word "beet". Wild "Beta" species can be found throughout the Atlantic coast of Europe, the Mediterranean coastline, the Near East, and parts of Asia including India. This genus consists of annual, biennial, or perennial species, often with fleshy, thickened roots.
