Pear Psylla
A small winged psyllid that is the most important insect pest of European pear orchards. Nymphs produce copious honeydew that causes fruit russeting and sooty mold.
Did You Know?
It can inject a toxin while feeding that causes a condition called psylla shock, which can kill young pear trees.
Corn Earworm
A highly polyphagous moth whose caterpillars feed inside corn ears, tomato fruits, and cotton bolls. It is one of the costliest crop pests in the Americas.
Did You Know?
Caterpillars are cannibalistic, so usually only one survives per corn ear.
