''Manduca sexta'' is a moth of the family Sphingidae present through much of the American continent. Commonly known as the Carolina sphinx moth (as adults) and the tobacco hornworm and the goliath worm (as larvae), it is closely related to and often confused with the very similar tomato hornworm (''Manduca quinquemaculata''); the larvae of both feed on the foliage of various plants of the family Solanaceae. The tobacco hornworm is sometimes kept as a pet by children throughout its range. It can be distinguished by its seven diagonal lines on its sides; tomato hornworms have eight V-shaped markings. A mnemonic to remember the markings is tobacco hornworms have straight white lines like cigarettes, while tomato hornworms have V-shaped markings (as in "vine-ripened" tomatoes). ''M. sexta'' has mechanisms for selectively sequestering and secreting the neurotoxin nicotine present in tobacco. ''M. sexta'' is a common model organism, especially in neurobiology, due to its easily accessible nervous system and short life cycle. It is used in a variety of biomedical and biological scientific experiments. It can be easily raised on a wheat-germ-based diet. The larva is large, and thus it is relatively easy to dissect it and isolate its organs. ==Subspecies== *''Manduca sexta caestri'' (Blanchard, 1854) (Chile) *''Manduca sexta jamaicensis'' (Butler, 1875) (Caribbean) *''Manduca sexta leucoptera'' (Rothschild & Jordan, 1903) (Galápagos Islands) *''Manduca sexta paphus'' (Cramer, 1779) (South America) *''Manduca sexta saliensis'' (Kernbach, 1964) (Argentina) *''Manduca sexta sexta'' (Americas) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Manduca sexta」の詳細全文を読む スポンサード リンク
