Abstract

The application field of drone has diversified greatly over the past decade. This can be explainedby its democratization and versatility. Indeed, it is involved in many fields as it can be associatedwith numerous technologies (captors, cameras. . . ). The chemical ecology is no exception. Thisscientific discipline is interested in the development of biological control techniques. Among thesetechniques, the observation of odor profiles changes in infested crops is promising as earlyinfestation diagnosis. Indeed, a crop infested by a pest emits particular odors. Sometimes, thepest itself emits odors which permits its identification (in the form of sexual or aggregationpheromone). This master thesis aims to use drones for crop pest detection. The bark beetle waschosen as the study model, as its strong proliferation and the lack of control techniques availablenowadays. For this purpose, a sampling method of VOCs using drone was developed inlaboratory and tested in the field. After the selection of some VOCs (alpha-Pinene,cis-3-Hexen-1-ol, beta-Caryophyllene), the operating parameters effect like the height, the airsampled volume and the flow rate on the amount of sampled VOCs was investigated. Somescale-ups were carried out, starting from without drone indoor samplings to outdoor with dronesamplings, in order to confirm the impact of pre-mentioned operating parameters. Followingthese experimentations, surface responses (contour and persp) were calculated in order to set theoperating parameters allowing an efficient VOCs sampling on the field. The air sampled volumewas the most influent parameter on the collected VOCs amount. The height had also an effect,but much less significant than the first. A validation application above anIps Typographusbarkbeetle infested spruces plantation allowed the VOCs detection released by the crop, as well astwo bark beetles aggregation pheromones. This technique is therefore promising in the diagnosisof bark beetle, thus limiting losses by producers.

Abstract

The great potential of remote sensing technologies for operational use in sustainable forest management is addressed in this book, which is the reprint of papers published in the Remote Sensing Special Issue “Operationalization of Remote Sensing Solutions for Sustainable Forest Management”. The studies come from three continents and cover multiple remote sensing systems (including terrestrial mobile laser scanning, unmanned aerial vehicles, airborne laser scanning, and satellite data acquisition) and a diversity of data processing algorithms, with a focus on machine learning approaches. The focus of the studies ranges from identification and characterization of individual trees to deriving national- or even continental-level forest attributes and maps. There are studies carefully describing exercises on the case study level, and there are also studies introducing new methodologies for transdisciplinary remote sensing applications. Even though most of the authors look forward to continuing their research, nearly all studies introduced are ready for operational use or have already been implemented in practical forestry.

Abstract

After the successful conclusion of the Joint Meeting of IUFRO's 7.03.05 & 7.03.10 working parties and given the exciting and novel studies that have been presented in the framework of this meeting, we decided to present some of these studies in the current Special Issue of Forests. To make this issue more appealing and interesting to everyone in the field of Forest Protection, studies that cover a wide range of topics were selected, ranging from ecology and phylogeography to forest management and protection. More importantly, as these studies refer to pests and pathogens from different parts of the world, it is expected that the knowledge gained can be further used in the protection of natural environment worldwide.

Abstract

Forests are the richest and most complex ecosystems in the world. Due to the abundance of species and their intricate relationships, huge problems are faced when investigating and analyzing them, despite the fact that increasingly sophisticated research tools are currently available. This is also true in the case of the largest group of animals in the world, i.e., insects inhabiting the forest environment. We are currently living in times of dramatic environmental changes triggered by human activity. The effects of climate change are evident and lead to changes in forests. Growing numbers of insect species are being threatened, and it is our responsibility to protect them. This Special Issue of our journal aims to provide a platform for scientific discussions on an array of research problems, such as geographic or historic diversity of forest insects, their variability, habitat preferences, as well as their monitoring or use as bioindicators of environmental changes. We are convinced that this Special Issue will not only be a source of inspiration for further research but will also contribute to reaching a reasonable compromise between the necessary protection of forests and the need for economic benefits. It is our belief that entomological studies will be of considerable value in these efforts.
