Talk title The elucidation of adaptation mechanisms in spider mites: recent progress and future perspectives
The main research interests of Thomas Van Leeuwen center on the physiology, genetics, genomics and molecular biology of adaptive mechanisms in spider mites such as Tetranychus urticae in relation to the xenobiotic metabolism and resistance. This entails the study of acaricide resistance, as well as mechanisms of adaptation to novel host plants, including plant-mite molecular interactions. The overall aim is to develop Tetranychus urticae into a model polyphagous crop pest, which is supported by a strong interest in the development of functional tools such as recombinant expression, NGS-based high resolution genetic mapping, and methods of forward and reverse genetics.

Talk title From mite ecology to applied acarology in Neotropical agroecossystems
Researching on mite ecology, applied acarology in agroecossystems with emphasis on the ecology of an invasive mite species, Tetranychus evansi, and how it manipulates plant defense to is own sake. We found that while T. urticae up-regulates plant defenses, T. evansi decreases tomato plant defenses to levels below that in uninfested plants for its own benefit. It down-regulates both jasmonic and salicylic acid pathways, responsible for both direct and indirect plant defenses. Were are studying the key playersand their interactions in the food web occurring in the system. Additionally, my Lab investigates food web ecology and biological control in agroecosystems as coffee, strawberry, litchi, chili peppers, and eucalyptus/guava trees.

Talk title A novel method for protecting slow-release sachets of predatory mites (Neoseiulus californicus) against environmental stresses and for increasing predator release to greenhouse crops
Dr Takeshi Shimoda is an entomologist studying tritrophic interactions between plants, herbivores and their natural enemies. He is interested in the role of insect and mite predators in controlling spider mites in orchards. He recently joined as a leader a research project (2014-2017) that aims to develop “sheltered sachets of predatory mites”. Sheltered sachets that are commercially available in Japan can protect slow-release sachets of predatory mites (e.g. Neoseiulus californicus or Amblyseius swirskii) against environmental stresses (e.g. pesticides, drenching) and thus enhance the predator’s release in crops.

Talk title Why multidisciplinary approaches for controlling mite pests?
Marie-Stéphane Tixier is a professor in crop protection in Montpellier SupAgro (France) and head of the Department Biology and Ecology ((https://www.supagro.fr/). She develops her research in the research unit of “Centre de Biologie et de gestion des populations”. Her research activity deals with the taxonomy of the mite family of Phytoseiidae (Acari: Mesostigmata): diagnostic, ecology, biodiversity, biogeography and phylogeny of the family and the use of those mites for biological control in various crops, mainly vineyards, orchards and tomato crops. As key recent activities, she coordinates the MOOC Nectar on challenges of taxonomy of arthropods and nematodes for agriculture, the web site containing on-line identification keys and the project research Acarosol that aims to develop new biological control solutions for controlling mite pests in tomato crops.
