Olive psyllid,
Euphyllura
spp. (Hemiptera: Psyllidae), is a pest that is seen commonly in the olive production areas in Turkey. The pest causes the shoots to weaken, flower and flower buds to shed, trees to weaken in dense populations, causes loss of quality and yield in olive due to the honey-like substance they secrete, which causes fumagine. In this study, surveys were conducted to determine the distribution area of the olive psyilid in 11 districts of Hatay province in the period 2018–2019, and investigations were made in order to determine their population change and natural enemies in two orchards in Altınözü and Antakya districts.
Euphyllura straminea
Loginova was determined as the sole species in Hatay province, and infection was determined as 100%. After June, the egg and nymph stages of the pest were not found until March of the following year, while the adult stage continued to exist throughout the winter. It was determined that
E. straminea
has two overlapping generations in Hatay province of Turkey. During the study,
Pharoscymnus pharoides
(Marsuel),
Anthocoris nemoralis
(Fabricius) and
Pseudoloxops coccineus
(Meyer-Dur) was determined as the most abundant natural enemy species.
