Nicotiana
Template:Short description Template:For Template:Automatic taxobox
Nicotiana (Template:IPAc-enTemplate:RefnTemplate:Refn<ref>Sunset Western Garden Book, 1995:606–607</ref>) is a genus of herbaceous plants and shrubs in the family Solanaceae, that is indigenous to the Americas, Australia, Southwestern Africa and the South Pacific. Various Nicotiana species, commonly referred to as tobacco plants, are cultivated as ornamental garden plants. N. tabacum is grown worldwide for the cultivation of tobacco leaves used for manufacturing and producing tobacco products, including cigars, cigarillos, cigarettes, chewing tobacco, dipping tobacco, snuff, and snus.

Etymology
[edit]The genus Nicotiana (from which the word nicotine is derived) was named in honor of Jean Nicot, French ambassador to Portugal, who in 1559 sent samples as a medicine to the court of Catherine de' Medici.<ref>Template:Cite web</ref>
Ecology
[edit]_BHL41830187.jpg){kind=link}
Despite containing enough nicotine and/or other compounds such as germacrene and anabasine and other piperidine alkaloids (varying between species) to deter most herbivores,<ref>Template:Cite journal</ref> a number of such animals have evolved the ability to feed on Nicotiana species without being harmed. Nonetheless, tobacco is unpalatable to many species and therefore some tobacco plants (mainly tree tobacco (N. glauca)) have become established as invasive species in some places.<ref name=bionet-eafrinet>Template:Cite web</ref>
In the 19th century, young tobacco plantings came under increasing attack from flea beetles (particularly the potato flea beetle (Epitrix cucumeris) and/or Epitrix pubescens), causing the destruction of half the United States tobacco crop in 1876. In the years afterward, many experiments were attempted and discussed to control the potato flea beetle. By 1880, it was discovered that covering young plants with a frame covered with thin fabric (instead of with branches, as had previously been used for frost control) would effectively protect the plants from the beetle. This practice spread until it became ubiquitous in the 1890s.Template:Citation needed
Tobacco, alongside its related products, can be infested by parasites such as the tobacco beetle (Lasioderma serricorne) and the tobacco moth (Ephestia elutella), which are the most widespread and damaging pests in the tobacco industry.<ref name="Ryan 1995">Template:Cite book</ref> Infestation can range from the tobacco cultivated in the fields to the leaves used for manufacturing cigars, cigarillos, cigarettes, chewing tobacco, dipping tobacco, snuff, snus, etc.<ref name="Ryan 1995"/> Both the grubs of Lasioderma serricorne and the caterpillars of Ephestia elutella are considered major pests.<ref name="Ryan 1995"/>
Other moths whose caterpillars feed on Nicotiana include:
- Black cutworm, greasy cutworm, or floodplain cutworm (as a caterpillar), dark sword-grass or ipsilon dart (as a moth) (Agrotis ipsilon)
- Turnip moth (Agrotis segetum)
- Mouse moth (Amphipyra tragopoginis)
- Clover cutworm (as a caterpillar), nutmeg (as a moth) (Hadula trifolii or Anarta trifolii)
- Endoclita excrescens
- Hawaiian tobacco hornworm or Hawaiian tomato hornworm (as a caterpillar), Blackburn's sphinx moth (as a moth) (Manduca blackburni)
- Tobacco hornworm or Goliath worm (as a caterpillar), tobacco hawkmoth or Carolina sphinx moth (as a moth) (Manduca sexta)
- Tomato hornworm (as a caterpillar), five-spotted hawkmoth (as a moth) (Manduca quinquemaculata)
- Cabbage moth (Mamestra brassicae)
- Angle shades (Phlogophora meticulosa)
- Setaceous Hebrew character (Xestia c-nigrum)
- Cabbage looper (Trichoplusia ni)<ref>United States. Agricultural Research Service (1984), Suppression and Management of Cabbage Looper Populations, U.S. States Dept. of Agriculture, retrieved 25 September 2017</ref>
- Fall armyworm (Spodoptera frugiperda)
- Tobacco spitworm (as a caterpillar), potato tuber moth (as a moth) (Phthorimaea operculella)<ref name=Hayden-eal-2013>Template:Cite web</ref>
- South American tomato pinworm, tomato pinworm or tomato leafminer (as a caterpillar), South American tomato moth (as a moth) (Tuta absoluta)<ref name=Hayden-eal-2013/>
- Eggplant leafroller moth or nightshade leaftier (Lineodes integra)<ref name=Hayden-eal-2013/>
- Eggplant webworm moth (Rhectocraspeda periusalis)<ref name=Hayden-eal-2013/>
These are mainly Noctuidae, but they also comprise Sphingidae, Gelechiidae, and Crambidae.
Cultivation
[edit]Several species of Nicotiana, such as N. sylvestris,<ref>Template:Cite web</ref> N. alata 'Lime Green'<ref>Template:Cite web</ref><ref name=rhsnicalat/> and N. langsdorffii are grown as ornamental plants, often under the name of flowering tobacco.<ref name=FG/><ref name=NGB>Template:Cite web</ref> They are popular vespertines (evening bloomers); their sweet-smelling flowers opening in the evening to be visited by hawkmoths and other pollinators. In temperate climates, they behave as annuals (hardiness 9a–11).<ref>Template:Cite web</ref> The hybrid cultivar 'Lime Green'<ref name=rhsnicalat>Template:Cite web</ref> has gained the Royal Horticultural Society's Award of Garden Merit.<ref>Template:Cite web</ref>
Garden varieties are derived from N. alata (e.g., the 'Niki' and 'Saratoga' series) and more recently from Nicotiana × sanderae (e.g., the 'Perfume' and 'Domino' series).<ref name=NGB/>
The tobacco budworm (Chloridea virescens) has proved to be a massive "pest" of many species in the genus, and has resisted many attempts at management.<ref>Template:Cite web</ref>
