During the post-entry quarantine inspection of olive seedlings imported from the Netherlands, the olive psyllid, Euphyllura olivina (Costa, 1839), was accidentally intercepted in June 2020. This study reports the presence of the olive psyllid for the first time in the East Palaearctic region, South Korea.

Contributions to the reproductive biology of olive psylla Euphyllura olivina Costa (Hom., Psyllidae)
AbstractSeasonal reproductive development was investigated in females of olive psylla. Samples of females taken from two olive orchards in a 2 yr period were dissected for monitoring reproductive status. Five distinct stages of ovariole formation and development were recorded.

Abstract Olive mill wastewater (OMW) is a problematic by-product in Mediterranean countries. Despite this, it is a raw material that is an unfailing source of bioactive molecules. A hydroxytyrosol-rich preparation (HRP) (49.6% weight:dry weight) was extracted from fresh OMW using a hydrolysis and post-hydrolysis purification process.

Results from physicochemical analysis of olive mill wastewater (OMW) have shown that total suspended solids (5.170 to 0.658 g/L), chemical oxygen demand (124.400 ± 25.442 g/L), biochemical oxygen demand (60.593 ± 6.276), total organic carbon (3.317 ± 0.350 g/L), and Kjeldahl nitrogen (0.126 ± 0.044 g/L) far exceed discharge standards.

Factors affecting the distribution of Euphyllura olivina Costa (Hom., Psyllidae) on olive
AbstractThe adult population of E. olivina showed two generations annually in mid‐May and in end June. The summer generation caused a significant economic loss to olive fruit. In all observations, nymphal infestation was mainly found close to the fruits. The spatial distribution of nymphal infestation was related to the heat of sunrays. New measures of

The seasonal changes in water content and fat content of olive psylla, Euphyllura olivina in the field were investigated in two successive years. The overwintering adults of olive psylla had more fat than spring and summer generation adults. There was a steady increase in % fat contents of females from mid-October to early January.

We have studied, in Euphyllura olivina Costa, 1839, the incidence that the absence or presence of males can have on the fecundity of females their longevity, the duration of spawning and other biotic parameters... So we have pointed out that: In all the cases, from beginning of experimental infestations of olive--tree sprouts to the beginning of eggs ...
