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 Nagorno-Karabakh 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.
