The E14 munition was a cardboard sub-munition (air-dropped or ground-launched munitions that eject smaller submunitions) developed by the United States biological weapons program as an anti-crop weapon. In 1955 the E14 was used in a series of field tests, during the tests the munition was loaded with fleas and air-dropped. ==History== The E14 munition was developed by the United States for use in its offensive biological warfare arsenal as an anti-crop weapon.〔 After the Korean War U.S. interest in large-scale entomological warfare increased.〔 The E14 was one of two sub-munitions used in large-scale testing aimed at learning the feasibility and result of an air-dropped insect attack.〔 In September 1954, at Dugway Proving Ground in Utah, the E14 was again used in a series of tests known as "Operation Big Itch".〔 During Big Itch, uninfected rat fleas〔The rat flea is a known vector for bubonic plague. See: Trivedi, "Xenopsylla cheopis".〕 (''Xenopsylla cheopis'') were loaded into the E14 and air-dropped over the proving ground.〔 The E14 used cardboard and sponge inserts to hold the fleas inside the cardboard container.〔 With the sponge inserts in place, the E14 could hold about 100,000 fleas.〔 Eighty cardboard inserts, or "loop tubes", could be carried in the E14 as well. The munition could hold 80 loop tubes, each one capable of holding 3,000 fleas.〔 The testing in Utah was ultimately successful.〔〔Rose, William H.

See: Russell, "Aedes aegypti".〕 (''Aedes aegypti''). The successful Georgia trials were known as "Operation Big Buzz".〔 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「E14 munition」の詳細全文を読む スポンサード リンク
