The iSCOUT color trap is a field device consisting of a camera mounted in front of a sticky trap. A couple of times a day this camera makes a picture and sends this image to a central server. The image is automatically analyzed and the number of insects is counted. Only insects of a certain size are detected, if an insect is too small it won’t be recognized. Aphids used to be too small to be detected, but due to the work done for the R&D voucher, PESSL Instruments received in 2021, ‘Automatic aphid detection in potato fields’ the iSCOUT Color trap can now recognize and count aphids on yellow sticky plates. In this voucher project we will work on two work packages: WP1 in which the iSCOUT Color trap is validated next to standard-used methods to monitor aphids, WP2 in which the trap is better optimized for aphid catching while catches of other biodiversity are reduced.
