The potato psyllid is a small insect that primarily affects potato and other members of the Solanaceae family, such as tomatoes and eggplants. It is known for its ability to transmit harmful bacteria, particularly the one that causes zebra chip disease, which can severely damage crops and reduce yields. These insects are typically found in warm climates and can reproduce quickly, making them a significant pest for farmers. Effective management strategies include monitoring for their presence and using insecticides or natural predators to control their populations, helping to protect valuable crops from damage.
