Varroa destructor detection on honey bees using hyperspectral imagery
CoRR(2024)
摘要
Hyperspectral (HS) imagery in agriculture is becoming increasingly common.
These images have the advantage of higher spectral resolution. Advanced
spectral processing techniques are required to unlock the information potential
in these HS images. The present paper introduces a method rooted in
multivariate statistics designed to detect parasitic Varroa destructor mites on
the body of western honey bee Apis mellifera, enabling easier and continuous
monitoring of the bee hives. The methodology explores unsupervised (K-means++)
and recently developed supervised (Kernel Flows - Partial Least-Squares,
KF-PLS) methods for parasitic identification. Additionally, in light of the
emergence of custom-band multispectral cameras, the present research outlines a
strategy for identifying the specific wavelengths necessary for effective
bee-mite separation, suitable for implementation in a custom-band camera.
Illustrated with a real-case dataset, our findings demonstrate that as few as
four spectral bands are sufficient for accurate parasite identification.
