The Distribution of Agromyza Species in Nagorno-Karabakh Region and Infestation Rate of Host Plants

Grigoryan, N.M. and V.S. Hovhannisyan. 2024. The Distribution of Agromyza Species in Nagorno-Karabakh Region and Infestation Rate of Host Plants. Arab Journal of Plant Protection, 42(4): 461-464. https://doi.org/10.22268/AJPP-001278 In a survey carried out during the period 2019-2022, two species of Agromyza (Diptera: Agromyzidae) were identified for the first time in Nagorno-Karabakh region: A. parca and A. varifrons. This study focused on these species’ description, distribution, infestation of host plants and determination of some morphometric measurements. High infestation rate (65-70%) was noted on Alopecurus pratensis. Morphometric measurements confirmed the presence of sexual dimorphism in both identified species, especially the male wing length of A. parca in NagornoKarabakh was shorter by 0.7-0.9 mm, and in females 0.3-0.6 mm, whereas the wing length of A. varifrons was shorter by 0.5-0.8 mm.
