The presence, for the first time, of Melanagromyza sojae (Zehntner) (Diptera: Agromyzidae) in chickpea crops ( Cicer arietinum ) was confirmed in Argentina via morphological and molecular characterization of the cytochrome oxidase-1 gene from mtDNA. This species is highly oligophagous, preferring to infest Fabaceae plants, such as soybean and other beans. In South America, M. sojae was reported in Brazil, Paraguay and Bolivia causing damage in soybean crops. Unusual damages were observed in chickpea plants during the 2019 season in the province of Córdoba (Argentina). First, these damages were attributed to the occurrence of soil diseases ( Fusarium sp.). However, many of the affected plants had dipteran larvae boring inside the stem, resulting in some cases, plant’s death. In this study, all pupae collected form chickpea plants and adults obtained were identified as M. sojae. Further studies should be conducted to determine the distribution of this species in Argentina and its potential as a pest of soybean and chickpea crops, as well as to develop effective control methods.

大豆茎蝇 Melanagromyza sojae（双翅目：Agromyzidae）在鹰嘴豆作物中的首次记录

在阿根廷，通过 mtDNA 中细胞色素氧化酶-1 基因的形态学和分子表征，首次证实鹰嘴豆作物（Cicer arietinum）中存在大豆黑粉菌（Zehntner）（双翅目：Agromyzidae）。该物种是高度寡食性的，更喜欢感染豆科植物，如大豆和其他豆类。在南美洲，巴西、巴拉圭和玻利维亚报告称，大豆分枝杆菌对大豆作物造成损害。在 2019 年的科尔多瓦省（阿根廷）鹰嘴豆植物中观察到异常损坏。首先，这些损害归因于土壤病害（镰刀菌属）的发生。然而，许多受影响的植物在茎内钻了双翅目幼虫，在某些情况下导致植物死亡。在这项研究中，从鹰嘴豆植物中收集的所有蛹和获得的成虫都被鉴定为M. sojae。应进行进一步研究以确定该物种在阿根廷的分布及其作为大豆和鹰嘴豆作物害虫的潜力，并制定有效的控制方法。
