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) Nasturtium (genus) Nasturtium () is a genus of seven plant species in the family Brassicaceae (cabbage family), best known for the edible watercresses "Nasturtium microphyllum" ("Rorippa microphylla") and "Nasturtium officinale" ("R. nasturtium-aquaticum"). "Nasturtium" was previously synonymised with "Rorippa", but molecular evidence supports its maintenance as a distinct genus more closely related to "Cardamine" than to "Rorippa" "sensu stricto" (Al-Shehbaz & Price, 1998; Al-Shehbaz, Beilstein & Kellogg, 2006). Watercress or yellowcress is a common name for plants in this genus. These plants are related to garden cress and mustard, noteworthy for a peppery, tangy (pungent) flavor. The name Nasturtium comes from
