Plant protease inhibitors (PIs) are natural plant defense proteins that inhibit proteases of
invading insect herbivores. However, their anti-insect efficacy is determined not only by their …

Insects are the most abundant and diverse class of animals on the planet. One explanation
for their success is their extraordinary ability to successfully consume a wide range of foods …
