Finding Thrips

Pests and Diseases of Plants
How can the presence of pear thrips be detected in a prune orchard? Will
the distillate emulsion-nicotine spray control brown scale as well as
thrips?
You can find thrips by shaking a cluster of blossoms, as soon as they
open, over a sheet of paper or in the palm of your hand. The thrips are
very minute, transparent, somewhat louse-like insects. The spray you
mention would probably have little effect on the brown scale which would
still be in the egg state and under cover, at the time the early spring
spraying for the thrips.
