“…the outbreaks was identified as D. platura. However, since D. platura and D. sanctijacobi are very similar, it is possible that these specimens were misindentifed as D. platura, at least in some cases, as discussed byGoMes et al (2022).In Argentina, D. sanctijacobi was recorded on different host plants: alfalfa (Medicago sativa L.), oat (Avena sativa L.), wheat (Triticum sp. ), bean (Vicia faba L.), potato (Solanum tuberosum L.), beet (Beta vulgaris L.), and lettuce (Lactuca sativa L.)(haMity & roMan 1987).…”

“…Alternative pest management methods have been recommended to farmers, such as not transplanting over seedling production beds, not hurting the seedlings during transplanting, using welldecomposed organic matter, and eliminating crop residues. Even though damages caused by D. platura on different plants of economic interest in Brazil have been recorded(link & costa 1981;Boff 1991;Gonçalves 2006), it is probably D. sanctijacobi(GoMes et al 2022).…”

Delia Robineau-Desvoidy, composed of flies popularly known as root maggot flies, is a diverse genus with unclear delimitation. It comprises polyphagous species and some important agricultural pests. Delia sanctijacobi (Bigot) is native to South America, occurring in Argentina, Brazil, Chile, Peru, and Uruguay; the larvae are commonly known as “potato worms” and have been misidentified as Delia platura (Meigen) in Brazil. Delia sanctijacobi attacks the seeds and seedlings of several plants of commercial importance. We present new geographic records of D. sanctijacobi in Brazil and describe the damage caused by their larvae on commercial bean and onion in Paraná and Santa Catarina between 2019-2022.

“…Chile is not recorded yet as a distribution area of D. antiqua in CABI or EPPO Global Database of plant pest distribution. Although Gomes et al [60] suggested that the records of the Delia species in South America require review because they may be D. sanctijacobi, but the distribution of D. antiqua in Chile seems possible from a climatic point view (Supplementary File S2 Sheet S1F). This hypothesis will need to be further tested in the future.…”

The onion maggot, Delia antiqua (Meigen), is one of the most important insect pests to agricultural crops within Allium genus, such as onions and garlic, worldwide. This study was conducted to understand the seasonal abundance of this pest, with special reference to the hot summer effect (HSE), which was incorporated into the model of summer diapause termination (SDT). We assumed that hot summer temperatures arrested the development of pupae during summer diapause. The estimated SDT curve showed that it occurred below a high-temperature limit of 22.1 °C and peaked at 16 °C. Accordingly, HSE resulted in delaying the late season fly abundance after summer, namely impacting the third generation. In Jinju, South Korea, the activity of D. antiqua was observed to cease for more than two months in the hot summer and this pattern was well described by model outputs. In the warmer Jeju Island region, Korea, the late season emergence was predicted to be greatly delayed, and D. antiqua did not exhibit a specific peak in the late season in the field. The abundance patterns observed in Korea were very different from those in countries such as the United States, Canada, and Germany. These regions are located at a much higher latitude (42° N to 53° N) than Korea (33° N to 35° N), and their HSE was less intense, showing overlapped or slightly separated second and third generation peaks. Consequently, our modeling approach for the summer diapause termination effectively explained the abundance patterns of D. antiqua in the late season. Also, the model will be useful for determining spray timing for emerging adults in late summer as onion and garlic are sown in the autumn in Korea.
