DESCRIPTION:Special presentation by Dr. Julie-Éléonore Maisonhaute\, Centre
  de recherche agroalimentaire de Mirabel (CRAM). Everyone is welcome to at
 tend.\n\nLandscape ecology\, which aims to understand the relationship bet
 ween spatial context and ecological processes\, can be applied to many eco
 systems including agroecosystems. The basics of landscape ecology include 
 concepts such as spatiotemporal dynamics of landscapes\, landscape composi
 tion (ex. heterogeneity)\, landscape configuration (ex. fragmentation)\, a
 nd landscape perturbations. For the past few decades\, an increasing numbe
 r of studies have applied landscape ecology concepts to agroecosystems\, f
 ocusing on the effect of the spatial context on the population dynamics of
  pests or natural enemies. Landscape ecology applied to agroecosystems pla
 ys an important role in plant Integrated Pest Management (IPM)\, as it can
  help to model population dynamics of both pests and natural enemies (whic
 h landscape components have significant effects?)\, make predictions about
  future infestations (which landscape components are associated with lower
 /higher infestations?) or implement biological control programs (which lan
 dscape components are beneficial for natural enemies and associated with a
  more efficient control of pests?). For instance\, managing agricultural l
 andscape\, such as conserving non-crop areas or implementing strip croppin
 g\, have been showed to have significant positive effects on natural enemi
 es and conservative biological control. Scale is also an important paramet
 er to take into account\, since species of arthropods respond differently 
 to landscape structure\, from a very local/fine scale to a large/regional 
 scale. How spatial context can affect arthropod communities in agroecosyst
 ems and how it can be used in plant IPM will be further discussed using ex
 amples of an invasive pest (the soybean aphid) and natural enemy communiti
 es (aphidophagous guild and ground beetles). For instance\, studies have r
 evealed that the effect of the spatial context on the soybean aphid highly
  depends on the invasion sequence\, involving effects of summer host (soyb
 ean)\, overwintering host (buckthorn or woodland) or crop diversity\, whil
 e studies on natural enemies in corn system have showed temporal variation
  of the effect of the spatial context\, as well as variations between spec
 ies and trophic groups. All of these effects of landscape context on pests
  and natural enemies should be taken into account when implementing plant 
 IPM programs.\n
