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
Hystrix (plant) Other species placed in "Hystrix" have genomes more closely resembling those of "Leymus" species, and are better placed in that genus. Currently accepted transfers include: Hystrix (plant) Hystrix was a formerly recognized genus of grass (family Poaceae). The genus "Hystrix" was created in 1794 by Conrad Moench for the species described as "Elymus hystrix" by Carl Linnaeus in 1753. Moench considered that "E. hystrix" was sufficiently distinct to be placed in a separate genus as "Hystrix patula"; the genus was to be used for species without glumes or with long setaceous glumes. Subsequently a number of other grass species were
