Asian citrus psyllid confirmed in Rhodes orange groves

The Benaki Phytopathological Institute has confirmed the presence of the invasive insect Diaphorina citri, known as the Asian citrus psyllid, in orange groves on Rhodes. The insect has been detected in traps set within these orchards.

This pest is a carrier of bacteria that cause Huanglongbing (HLB), also known as citrus greening, one of the most destructive citrus diseases globally. The disease can cause trees to dry out within five to seven years. While the insect has not yet been detected in Crete, agricultural authorities in Heraklion are urging heightened vigilance and early symptom recognition.

Symptoms of infestation include the deformation and curling of young leaves, premature leaf drop, drying, and the growth of stunted shoots known as ‘witches’ broom’. The insect primarily attacks tender new growth. Authorities warn that the pest spreads over long distances through infested plant material and are urging strict caution during the movement of citrus plants and propagation material.
