Tsetse Flies in Africa: Bane or Boon?

摘要: : This paper examines the changing perception of role tsetse fly in development tropical Africa. The trypanosomiases transmitted by this group vector insects historically prevented establishment mixed (i.e., arable and livestock) farming thus occurrence an agricultural revolution within potentially more productive humid zones continent. Initially colonial powers saw as bane African development, much policy was aimed at eradicating vectors directly or eliminating diseases they transmit. observation inefficient techniques fly-infested areas, coupled with overstocking cattle fly-free generally led to naive plans that often exacerbated very problems solve. presence fly, however, these mistakes from being widespread now provides a window opportunity for sensible acknowledges uniqueness soils ecosystems. Ecologists can play vital process, although absence relevant hard data still retards progress. Resumen: Este informe examina la variabilidad de percepcion del rol mosca tse-tse en el desarrollo lm regiones tropicales La tripanosomiasis transmitida por este grupo insectos vectores historicamente impedia establecimiento cultivos mixtos, arable, o ganaderia, y lo tanto posibilidud una revolucion agricola las zonas bumedas potencialmente mas productivas continente. Inicialmente, potencias coloniales percibian como elemento destructivo que Africa, siendo asi, muchas politicas estaban dirigidas erradicacion directa los eliminacion enfermedades transmitidas ellos. observacion tecnicas cultivo ineficientes areas infestadas moscas, conjuntamente con cria excesiva ganado vacuno libres generalmente conducian planes candidos frecuentemente agravaban problemas se babian propuesto resolver. Sin embargo, presencia estos errores alcanzaran mayores proporciones, tanto, boy provee oportunidad adecuada para un racional reconozca characteristicas unicas suelos ecosistemas Los ecologistas pueden jugar proceso, aunque ausencia documentacion numerica todavia retrase progreso.
