Abstract

Individual meteorological factors, particularly temperature and wind, directly influence the dispersal of arthropods, as do weather systems — formation and movement of air masses, cold and warm fronts, and air flows associated with topographical features such as mountains, valleys, bodies of water. Models have been recently developed that simulate the effects of many of these systems on airborne dispersal of insects. Also, some attention has recently been directed toward the behaviour of arthropods during weather conducive to dispersal. Clearly, both winged and wingless forms of arthropods respond to certain stimuli for dispersal and behave specifically to enhance the potential for migration. Recent progress toward understanding the interplay between insect movement and mesoscale weather is particularly relevant to pest management.

Résumé

Certains facteurs météorologiques, en particulier la température, et le vent, influencent directement la dispersion des arthropodes, tout comme les systèmes météorologiques : la formation et le mouvement des masses d'air, les fronts chauds et froids, et les déplacements d'air liés à la topographie des montagnes, des vallées et des masses d'eau. Des modèles récemment élaborés simulent les effets de plusieurs de ces systèmes sur la dispersion des insectes par la voie des airs. De plus, on s'est intéressé au comportement des arthropodes en réponse aux conditions météorologiques qui suscitent la dispersion. Il apparaît clairement que des arthropodes aussi bien ailés qu'aptères réagissent à certains stimulis par la dispersion et se comportent spécifiquement de façon à amplifier leur potentiel de migration. Les progrès récents de la compréhension des interactions entre les déplacements des insectes et la météo sont particulièrement pertinents en lutte intégrée.
