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
Yellow-banded poison dart frog fall in prices within the exotic pet trade, which is an alleviative factor to the problem of overharvesting. Yellow-banded poison dart frog The yellow-banded poison dart frog ("Dendrobates leucomelas"), also known as yellow-headed poison dart frog or bumblebee poison frog, is a poisonous frog from the genus "Dendrobates" of the family Dendrobatidae.
