Abstract

The African armyworm is a migrant moth which, in its larval form, can cause severe plagues which destroy cereal crops, sugarcane and pastures in many parts of Africa. This paper reviews the relevant aspects of a multidisciplinary study into the dispersal behaviour and re-concentration of moths, migratory flight, source areas, population upsurges and the seasonal movement of moths. It introduces the new concepts of primary and critical outbreaks.

Résumé

Le chénille léqionnaire c'est un phalène migrateur qui comme les larves en pêut manger tous nos cereales, nos cannes a sucre et aussi nos élévages en Afrique.

Ce document-ci examine les aspects pertinent d'un étude des routes divèrs pour étudier le dispersion et encore le concentration des phalènes, leurs vols d'émigration, places de naissance et leurs erruptions accroissement des populations et leurs mouvements saisonniers partout en Afrique.
