First record of the bay sucker Trioza alacris Flor (Triozidae: Hemiptera) in Syria

Abstract

This study was conducted in Latakia, Syria to identify the insect species that causes the rolling and abnormal growth of young leaves of bay laurel, Laurus nobilis. The insect species was identified as the bay sucker Trioza alacris. Short notes on the symptoms and nature of damage caused by this pest are provided in this study.

Two new records of jumping plant lice (Hemiptera: Triozidae) from Syria

“…The psyllid fauna of the Eastern Mediterranean is less studied than that of Southern Europe (Ouvrard, 2020). From Lebanon 34 species are reported (Zeidan‐Gèze & Burckhardt, 1998) and prior to the present records only 10 species were known in Syria (Zeity, 2018; Zeity and Mofleh, 2020) whereas from Italy, for example, almost 200 species are reported (Conci et al ., 1996).…”

“…Only 10 psyllid species have been previously reported from Syria (Zeity, 2018; Zeity and Mofleh, 2020). Here another two species are added, Phylloplecta trisignata and Trioza brevigenae .…”

Outbreak of Lauritrioza alacris (Flor, 1861) (Hemiptera, Triozidae) in a commercial plantation of bay laurel (Laurus nobilis L., Lauraceae) in Brazil

“…Later, it was transferred to the monotypic genus Lauritrioza proposed by Conci & Tamanini (1985), who characterized this genus based on morphology and biology of immatures and adults from Laurus nobilis L. However, Hodkinson (1990) considered the status of Lauritrioza doubtful, until a comprehensive revision of dozens of species related to the laurel psyllid be carried out. No revision has been carried out yet, and the laurel psyllid is named for some authors as T. alacris (e.g., Burckhardt & Queiroz 2012;Zeity 2018), and by other as L. alacris (e.g., Landi 1997;Ouvrard 2021). Burckhardt & Ouvrard (2012), who used Lauritrioza as a valid name for the genus, claimed that "... genera synonymised with Trioza which is treated, by most authors, as an artificial receptacle for species not showing any particular morphological modifications.…”

“…The eggs and the five immature stages were described by Weiss & Dickerson (1918), and the fifth instar was described and illustrated by Conci & Tamanini (1985). Adults feed on young leaves, which curl up, making them suitable egg-laying sites (Zeity 2018), but it is more likely that the sucking of the immatures induces the gall (D. Burckhardt, pers. comm.…”
