Using electron microscope images to reveal the anatomy of adult pear psylla (Cacopsylla pyricola)

Pear psylla (Cacopsylla pyricola) is a key pest of pear production and represents a serious challenge for pear growers. Little is known about the anatomical structures and sensory hairs used by this insect to perceive their environment, find mates, and detect optimal oviposition sites. Here we present detailed images of both male and female pear psylla using The FEI Quanta 600F environmental scanning electron microscope. These are the first detailed images of Cacopsylla pyricola sensory organs at this magnification, showing both male and female abdominal sensilla. This unique anatomical atlas will be a fundamental tool for future research on this important insect pest.
