The Potato Psyllid is a small insect that primarily affects potato plants and other members of the Solanaceae family, such as tomatoes and peppers. It is known for its ability to transmit harmful bacteria, particularly the Candidatus Liberibacter solanacearum, which causes a disease called “zebra chip” in potatoes. This disease can lead to significant crop losses and affects the quality of the harvested tubers. Adult potato psyllids are about 1/8 inch long and have a distinctive appearance with a greenish-yellow body and large, clear wings. They typically feed on the sap of plants, which can weaken the plants and lead to stunted growth. Effective management strategies include monitoring for their presence and using insecticides when necessary to protect crops.
