#1-05: Perspectives in mite IPM in agricultural ecosystems under climate change

Organizer: Joon-Ho Lee

For the last few decades we have been experiencing very fast development of environmental change, in particular, global warming related with climate change. As global warming is progressed, agricultural ecosystems, mainly field crops and horticultural crops systems, are easily assumed to be suffered more by pests like mites because they are poikilothermic and their intrinsic capacity of increase will increase as temperature increases. The impacts of global warming are universal but they may be spatially much heterogeneous like other environmental heterogeneity. Therefore, dynamics of mite populations may differ significantly in different crop and/or horticultural systems. Also, mite population dynamics is an output from rather complex biological interactions, plant-mite-natural enemy interactions. In addition, various crop management practices would affect the mite population dynamics. In the previous ICAs, various topics regarding mite management have been covered such as population dynamics, modeling, biological control, acaricide resistance management, plant-mite-predatory mite interactions, and so on. However, as global warming is becoming eminent, the whole strategy for the mite IPM perhaps needs to be changed, and this may be urgent. It is the right time to explore and share the past experience in changes in mite problems in various agricultural ecosystems, and practices and theories for mite population management, and finally synthesize these into producing novel management strategies for mites under this climate change.
