Whether as part of an on-farm pest management strategy or a nationwide biosecuirty surveillance network, early detection of insect pests is crucial to their suppression. Despite this, insect surveillance is still conducted with manually checked traps as it has been for decades. Internet-connected “smart” traps have the potential to bring this practice into the 21st century and reduce associated labour costs dramatically, but they raise the question of how to best sense an insect. Cameras may seem like an obvious choice but their impact in “smart” traps has been limited by power and data handling requirements along with the fact that many insect species simply look very similar and can be hard to correctly identify in a 2D image. For flying insects, low power 2D optical beam break type sensors provide a more elegant solution for both the realtime detection of insects as they enter a trap and the diagnosis of their species based on the speed and timbre of their wing beats.
