A Huge Library of Plant Pest and Disease Images and More
I recently came across a library of all kinds of images of pests, diseases and crops. It has lots of entries, such as “Bees of the United States”:
https://www.ipmimages.org/browse/projectsubject.cfm?proj=1154
Alkali bee
And images of citrus pests and diseases and even different cultivars of citrus, under “Citrus ID”:
https://www.ipmimages.org/browse/projectsubject.cfm?proj=108
'Xie Shan" citrus cultivar
And even a few avocado images:
https://www.ipmimages.org/browse/Areathumb.cfm?area=277
But there's a heck of a lot more.
Clicking on the different links and their volumes of images will take some time because of the shear number. The images have been collected as a public data base for not only academics, but also for the general public. At present, it's not too easy to search, but it's worth a look.
