Research regarding morphological aspects of Napomyza gymnostoma Loew.

Abstract

Napomyza gymnostoma Loew, 1858 is a leaf miner from Diptera: Agromyzidae which was originally described in 1858, in Poland. This leaf miner is a pest of Allium spp., particularly leek, onion, garlic, chive and also is a potential pest of ornamental Allium plants. At present, is widespread in most European countries. This species is invasive therefore it is a significant pest of Allium spp. Agromyzidae family is characterized by having a great morphological similarity between the sexes. For a correct species identification the most significant and stable structure in the male genitalia is the distal end of the aedeagus (distiphallus). In Romania, Napomyza gymnostoma was first recorded in 2007 and specimens were identified based on morphological characters.
