The boll weevil is a beetle that feeds on bolls, the seed-bearing capsules of cotton plants. Probably of Mexican or Central American origin, the boll weevil appeared in Texas about 1892, spread to most cotton-growing regions of the US, and eventually became responsible for the destruction of about 8% of the nation’s annual cotton crop. Eradication programs begun in 1978 have proven successful in many states. Why did the citizens of Enterprise, Alabama, erect a monument to the pest in 1919? Discuss
