Liriomyza spp. (Diptera: Agromyzidae) causes losses of 54 million dollars in beans Phaseolus vulgaris L. and spinach Spinacea oleracea L. (Pratt et al., 2017).The main agromizids that affect the system of production in the world are Liriomyza huidobrensis (Blanchard), L. trifolii (Burgess) and L. sativae (Blanchard) (Guantai et al., 2015). Females of these species oviposit within the leaves and larvae consume the mesophyll, and mine leaves of serpentine format (Parrella et al., 1985). Additionally, the females using her ovipositor to puncture the surface of leaf and facilitates the infection by pathogenic fungi as Alternaria leaf on Solanum lycopersicum L. (Durairaj et al., 2010). Infestations of L. huidobrensis in Allium sativum L. were reported in the Chile, China, Colombia, Indonesia and Spain (Weintraub, 2001;Weintraub et al., 2017). However, occurrences of Liriomyza spp. on A. sativum in Brazil were not reported. Higher infestations of pests and diseases in this crop may lead to changes in production and reduce the quality of the bulbs (Moura et al., 2013). Thus, the objective was to report, for the first time, the attack of the Liriomyza spp. on A. sativum in Brazil.Liriomyza spp. was collected on 50 garlic fields from March 2017 until August 2018. The evaluated garlic cultivars were Ito (46 fields-60 ha), Chonan (1 field-20 ha), Roxo pérola de caçador (1 field-35 ha) and Gravatá (2 fields-12 ha) in the municipality of Rio Paranaíba-MG (19°12'41.3" S; 46°13'56.9" W; altitude: 1,122 m). The evaluations were performed at 15, 75 and 135 days after the emergence of garlic. Five leaves ha -1 were random collected in each area. The leaves were collected placed in paper bags
