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
Golden poison frog semiopaca", "C. rugiceps" and "C. sp. A". Other related toxins, histrionicotoxin and pumiliotoxin, are found in frog species from the genus "Dendrobates". The golden poison frog, like most other poisonous frogs, stores its poison in skin glands. Due to their poison, the frogs are deterrent to predators; "P. terribilis" poison probably kills any predator, except for one snake species, "Liophis epinephelus". This snake may be resistant to the frog's poison, but is not immune (Myers & Daly, 1978). The poisonous frogs and birds themselves are perhaps the only creatures to be immune to this poison. Batrachotoxin attacks the sodium channels
