Abstract

Despite the growing acceptance and adoption of the IPM concept, up until now no “optimal” or pragmatic IPM programme has been realized. This is apparently because most of these programmes are still in need of new types of pesticides, with no or negligible adverse impact on the environment including the non-target beneficial arthropods. From a practical perspective, such pesticides are still rather far reaching. Most, if not all, pesticides in current use as components of IPM programmes are so far belonging, in one way or another, to the conventional pesticides. It is admitted that in designing IPM programmes, several efforts should be made to minimize not only the frequency of pesticide applications but also their negative consequences on beneficial arthropods. Whilst the first goal has been achieved in several situations, the other one appeared hardly accessible. A number of methodologies are currently being suggested to cause conventional pesticides more selective, but apart from having many technical and other constraints, they might at best have fallen short of providing the hopeful solution. These together with other problems facing the development and practical utilization of juvenoids and related compounds are discussed mainly in view of their possible contribution to tropical pest management.

Résumé

Bien que le concept MIP ait été reconnu et que son application pratique soit de plus en plus fréquente, aucun programme pragmatique satisfaisant n'a été réalisé jusqu'à présent.

Peut-être est-ce parce que la plupart de ces programmes demandent l'introduction de nouveaux types de pesticides exerçant peu ou pas d'action nocive sur l'envirronement y compris sur les arthropodes. Malheureusement, il est impossible que de tels pesticides soient fabriqués à plus ou moins brève échéance. En ce qui concerne la plupart des pesticides d'usage courant, comme ceux des programmes MIP, on doit s'appliquer à en diminuer non seulement la fréquence d'utilisation mais aussi l'action nocive sur les arthropodes.

Mais s'il est relativement facile d'atteindre le premier objectif, on se heurte à des problèmes insolubles quant au second. Par conséquent, on se contente généralement de proposer des méthodes permettant de rendre les pesticides conventionnels plus sélectifs, car les différentes contraintes, techniques et autres, constituent des obstacles insurmontables à la réalisation des solutions souhaitées. Tous ces problèmes ainsi que ceux auxquels on se heurte dans l'utilisation de plus en plus fréquente des juvénoîdes et produits similaires, sont au coeur des discussions, puisque leur solution rendra possible une lutte efficace contre les insectes nuisibles des régions tropicales.
