First results of research on the armored bush cricket (acanthopolus discoidalis) on pearl millet in Namibia : population dynamics, biology and control / B. Wohlleber

Public ISBD Accompagne Drought-tolerant crops for Southern Africa Titre : First results of research on the armored bush cricket (acanthopolus discoidalis) on pearl millet in Namibia : population dynamics, biology and control Type de document : texte imprimé Auteurs : B. Wohlleber, Auteur Editeur : ICRISAT Année de publication : 1996 Importance : p 163-172 Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : ACANTHOPOLUS DISCOIDALIS  MIL A CHANDELLE  NAMIBIE Résumé : Annual attacks by the bush cricket (Acanthopolus discoidalis) cause severe losses in pearl millet producton in Owamboland, Namibia of approximately 10 000t/y, e.g. 30% of the total harvest in 1993. Research in this study is geared to the development of an integrated pest management (IPM) system based on the biology and ecology of the cricket relevant to the socioeconomic environment of communal farmers in Namibia. Understanding of the biology and population dynamics of the cricket should provide adequate knowledge for the development of integrated pest management components with special emphasis on the development of a population forecasting method, then the development of yield loss evaluation methods in farmers’ fields, involving the quantification of development of cultural, biological and chemical control methods. The data reported comprise selected results from second-season trials and are therefore subject to later reassessment.
