This session covers the oldest interconnection between modern fields of Entomology, i.e., Systematics and Morphology. The study of insect systematics and morphology has changed over time, embracing new technologies and state-of-the-art analytical approaches, without neglecting traditional methods. Today -in the era of biodiversity-, insect systematics are more popular than ever. An alloy of molecular and morphological tools is being used to tackle stimulating questions regarding insect phylogeny, ecology, physiology, management and many other disciplines, always under the light of evolution.

In the years to come, urban environments and forest ecosystems are expected to be heavily affected both by native and invasive insect species. International trade and globalization facilitate the movement of insects beyond their natural range while changes in climatic and environmental regime not only allow the establishment of invasive species but even trigger population outbreaks of native ones. This session aims at presenting the latest advances in forest and urban entomology, highlighting the challenges in this changing environment.

Modern pest control largely depends on the application of insecticides and acaricides, but often hampered by the evolution of resistance. However, if resistance evolves, the understanding of molecular and genetic mechanisms is important to implement resistance management strategies. Likewise, the elucidation of mechanisms underlying metabolic and target-site resistance are crucial to overcome cross-resistance issues with novel mode of action. The field has recently gained momentum by several genomic and genetic tools allowing to dissect molecular interactions between agrochemicals and interacting proteins.

Stored product protection is a key element in safeguarding global food security. Post-harvest infestations by storage pests can cause serious quantitative losses and qualitative degradations. The term “stored products”, apart from durable food, also includes a wide range of non-food items, that vary from tobacco to museum artefacts. At the same time, many of these pests are also presented in the urban and the sub-urban environment, while, recently, certain stored product insect species have been approved for food and feed.
