:''"Potato beetle" redirects here. This can also refer to similar Chrysomelidae, e.g. Lema trilineata''.The Colorado potato beetle (''Leptinotarsa decemlineata''), also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle or the potato bug, is a major pest of potato crops. It is approximately long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. It can easily be confused with its close cousin and look-alike, the false potato beetle.==History==The beetle was discovered in 1824 by Thomas Say from specimens collected in the Rocky Mountains on buffalo-bur, ''Solanum rostratum''. The origin of the beetle is somewhat unclear, but it seems that Colorado and Mexico are a part of its native distribution in southwestern North America.(【引用サイトリンク】title=Featured creatures: ''Leptinotarsa'' spp. ) In about 1840, the species adopted the cultivated potato into its host range and it rapidly became a most destructive pest of potato crops. The large scale use of insecticides in agricultural crops effectively controlled the pest until it became resistant to DDT in the 1950s. Other pesticides have since been used but the insect has, over time, developed resistance to them all.
