Abstract

The growing recognition of problems associated with chemical pesticide use has led to increased attention on integrated pest management (IPM). This paper describes how Tunisian potato farmers have learned to manage an important field and postharvest insect pest, the potato tuber moth, Phthorimaea operculella (Zeller), and how interdisciplinary research on integrated pest management has contributed to this process. During the 1980s, new pest control technology and better farmer awareness led to changes in how farmers manage the potato tuber moth in their fields and stores. Farmers reduced insecticide treatments in potato fields and made more use of agronomic practices to avoid crop losses from the insect pest. New government regulations and agricultural extension efforts have caused farmers to discontinue use of environmentally harmful chemicals such as DDT. Research is continuing on biological insecticides that are not toxic to mammals and some farmer adoption of these products has occurred.

Résumé

La prise de conscience grandissante des problèmes liés à l’utilisation des pesticides chimiques attire de plus en plus l’attention sur la lutte intégrée. Cet article décrit comment les agriculteurs tunisiens ont appris à gérer les populations d’un insecte ravageur: la teigne de la pomme de terre. Il montre aussi, comment la recherche interdisciplinaire a contribué à ce processus. Durant les années 1980 une nouvelle technologie de contrôle ainsi qu’une meillure sensibilisation des agriculteurs, ont suscité des changements dans la manière dont ces derniers font face au problème de la teigne dans leurs champs et leurs entrepôts. Les agriculteurs n’utilisent plus autant de traitements insecticides dans les champs mais recourent de plus en plus aux techniques culturales afin d’éviter les pertes dues à ce ravageur. Les nouvelles réglementations et les efforts de vulgarisation poussent les agriculteurs à ne plus recourir aux produits chimiques néfastes pour l’environnement tel que le DDT. Actuellement la recherche se concentre sur la mise au point de l’utilisation des insecticides biologiques ainsi que sur leur adoption par certains agriculteurs.
