First record of pear lace bug Stephanitis pyri (F. 1775) on narrowleaf firethorn shrubs Pyracantha angustifolia (Franch.).

Abstract

In this study, the presence of pear lace bug Stephanitis pyri (F. 1775) was recorded for the first time in Syria on narrowleaf firethorn shrubs Pyracantha angustifolia (Franch.) C.K. Schneid. The adult insects of S. pyri were collected from several fruit orchards, containing narrowleaf firethorn shrubs as hedge plants, located in Khan Arnabah in Quneitra province during summer of 2016. Severe infestation symptoms covered the upper and lower surface of the leaves, which are the typical symptoms of insects of the genus Stephanitis. The insect was described morphologically and compared with the classification keys adopted for the genus Stephanitis. The biometric measurements of male and female were recorded after the last moulting and the beginning of wings coloration. The mean length of the adult insect was 2.95±0.078 and 2.94±0.101 mm, and its maximum width was 0.91±0.039 and 1.01±0.038 mm for male and female, respectively. Keywords: Pear lace bug, Stephanitis pyri, narrowleaf firethorn shrubs, Pyracantha angustifolia, Syria.
