11. Insect Event Extraction in LIDAR Images using Image Analysis and Convolutional Neural Networks
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : Insect monitoring has earlier been a manual, tedious and time consuming task that is impossible to do in real time. Thus there exists a need for a real time automatic insect monitoring system for counting and classifying insect for use in scientific research and pesticide spraying control. LÄS MER
12. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.

13. Can alteration in host odor blends change the olfactory preferences in Spodoptera littoralis?
Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)Sammanfattning : Gustatory and olfactory stimuli have been shown to induce feeding preferences in generalist phytophagous insect species. Generalists have to process a lot of information while performing host selection and it has been suggested that this may be a limitation, while it makes the host detection slower than for specialist species that process a lower amount of information.

14. Moth and Birch
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : The goal of this thesis is to build a near-real time defoliation detector that could be used, early in the spring, to find out which areas of a birch forest are being affected by an insect outbreak. The importance of a reliable detection at the beginning of the spring lies on the possibility for an early intervention. LÄS MER
15. Kilohertz electro-optics for remote sensing of insect dispersal
Master-uppsats, Lunds universitet/Fysiska institutionenSammanfattning : This thesis evaluates the possibilities of determining the flight direction of insects by analysing the wingbeat modulation pattern of the backscattered sunlight from insects. The Lund University Mobile Biosphere Observatory (LUMBO) was used during the summer of 2013 for a field campaign at two locations in Skåne, Sweden. LÄS MER
