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
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
