Human Impact
Lily leaf beetles leave considerable damage on host plants. Managing ornamental lilies has become difficult in regions where lily leaf beetles have established. Damage to the leaves and flowers can also leave the plants weakened and susceptible to diseases such as Lily grey mold.
The Canadian Maritime provinces, especially Fritillaria and Lilium gardens in Halifax, are largely affected by lily leaf beetles. A garden in Waverly, Nova Scotia has reported decline of lily species and cultivars from 50 in 1996 to only one species in 2006.

Famous quotes containing the words human and/or impact:
“Why was the human race created? Or at least why wasn’t something creditable created in place of it? God had His opportunity. He could have made a reputation. But no, He must commit this grotesque folly—a lark which must have cost Him a regret or two when He came to think it over and observe effects.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“As in political revolutions, so in paradigm choice—there is no standard higher than the assent of the relevant community. To discover how scientific revolutions are effected, we shall therefore have to examine not only the impact of nature and of logic, but also the techniques of persuasive argumentation effective within the quite special groups that constitute the community of scientists.”
—Thomas S. Kuhn (b. 1922)
