Agonopterix alstroemeriana with the dry weight of the leaf. However, oviposition was not correlated positively with the concentration of alkaloids in the poison hemlock, which varies widely among individual plants. Therefore, it is difficult to predict whether increased alkaloids in the plant would increase or decrease the use of the hemlock moth as a biological control. The effects that the alkaloids in "Conium maculatum" cause on the moth, both physiologically and behaviorally, are relatively unknown. Persons interested in the biological control capabilities of "A. alstroemeriana" see behavioral dependency on the host plant as an asset when using this moth as a biological
Mandragora (genus) Mandragora (genus) Mandragora is a plant genus belonging to the nightshade family (Solanaceae). Members of the genus are known as mandrakes. There are between three and five species in the genus. The one or two species found around the Mediterranean constitute the mandrake of ancient writers such as Dioscorides. Two or three further species are found eastwards into China. All are perennial herbaceous plants, with large tap-roots and leaves in the form of a rosette. Individual flowers are bell-shaped, whitish through to violet, and are followed by yellow or orange berries. Like many members of the Solanaceae, species of "Mandragora"
