First record of Heterotrioza chenopodii (Reuter, 1876) (Hemiptera: Psylloidea: Triozidae) in Tunisia

Abstract

This is the first report of the psyllid species, Heterotrioza chenopodii (Reuter, 1876), in Tunisia. This species was collected in November 2019 on Chenopodium album growing in the greenhouse of the Higher School of Agriculture, Kef, Northwestern Tunisia. Elements of colouration of adults and immatures are reported in this paper and considerations about the use of this species as a weed biocontrol agent are discussed.

Indian record of the old-world psyllid Heterotrioza chenopodii (Reuter) (Hemiptera, Psylloidea, Triozidae) on quinoa Chenopodium quinoa (Amaranthaceae)

“…H. chenopodiiis found to be an effective biological control agent against weeds (Haouas et al, 2021). Hence, a careful assessment of the host plant preference among Amaranthaceae members may be required for further pest risk analysis.The presently reported psyllid has no specific history in this geographical region and sequences of H. chenopodii generated are highly similar to the global population.…”

“…It feeds on a variety of Amaranthaceae plants including Amaranthus sp., Atriplex halimus, A. tatarica, Chenopodium album, C. glaucum, C. quinoa, Halimione portulacoides, Beta vulgaris and Spinacia oleracea (Mathur, 1975;Aguiar and Martin, 1999;Spodek et al, 2017;Ouvrard, 2020). Initially recorded from Finland (Reuter, 1876), H. chenopodii is now globally reported in new geographical locations (Mathur, 1975;Horton et al, 2018;Mifsud, 2020;Ouvrard, 2020;Percy et al, 2020;Haouas et al, 2021;Soliman et al, 2021). H. chenopodii induces leaf deformations and yellowing on the host plants.…”
