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
Nasturtium (genus) the Latin "nasus tortus", meaning "twisted nose", in reference to the effect on the nasal passages of eating the plants. "Nasturtium" foliage is used as food by the caterpillars of certain Lepidoptera, including "Orthonama obstipata" (The Gem). One species, "Nasturtium gambellii", is a federally listed endangered species in the United States. The genus "Nasturtium" should not be confused with the flowering garden annual commonly known as nasturtium ("Tropaeolum majus"). Though not related, the leaves of the garden nasturtium also have a peppery taste. One database names 316 species. Nasturtium (genus) Nasturtium () is a genus of seven plant species in
