Abstract

Precision agriculture needs integrated pest management IPM for which detection and identification of target invertebrate species is a prerequisite Researchers have been developing various technologies to detect pests more efficiently and accurately However these existing sensing technologies still have limitations for effective infield applications This review paper aims to explore the relative technologies and find a sensing method that has potential to detect and identify common invertebrates on crops such as butterflies locusts snails and slugs It was found that there are two main research branches for invertebrate detection and identification acoustic sensing and machine vision system MVS Acoustic sensing is suitable for detecting and identifying pests in soil stored grains and wood while usually acoustic sensors need to be attached to samples for inspection which causes difficulties for efficient infield applications MVS has the potential to provide a more effective and flexible way to detect and identify invertebrates on crops In recent work with MVS the technologies of invertebrate identification have been intensively studied however infield detection is relatively weak This review points out the current research gaps and then discusses the potential research directions
