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
Red-backed poison frog the second-most poisonous of the frogs in the genus "Ranitomeya". Its toxins are used as the frog's natural defense mechanisms, making them inedible to many, if not most, of the predators in its natural area. To advertise its poison and further reduce the risk of injury, the red-backed poison frog displays its brilliant warning colors, especially its red-orange back, for which it is named. Like all dendrobatids, it does not manufacture its poison itself, but rather is theorized to take the toxins from the ants, mites, and beetles on which it lives. It absorbs the insects' poisons into its body,
