“…Precipitation of the driest month, annual precipitation, temperature annual range, and minimum temperature of the coldest month were the variables that most contribute to the final model, showing an overall contribution of 91%. Highly suitable areas were estimated in regions with high precipitation in the driest months and with annual precipitation between 1800 and 3900 mm, which is in agreement with several studies demonstrating that the incidence level and damage caused by M. sojae is more severe during the rainy season (Singh & Beri, 1973; Abdel‐Banat et al, 2017; Fand et al, 2019). Also, the response curves indicated an increase in the species probability of occurrence in regions with higher minimum temperatures (see Figure S2), which is in accordance with the positive correlation between temperature and M. sojae incidence levels recorded under field conditions (Abdel‐Banat et al, 2017).…”

The soybean stem fly, Melanagromyza sojae (Zehntner) (Diptera: Agromyzidae), is an example of an insect pest with a restricted distribution that in the last few decades has been spreading to regions beyond its native range and causing economic losses. We evaluated whether M. sojae shifted its niche during biological invasion and used ecological niche models to estimate its global distribution under current and future climate conditions. In addition, we assessed whether the soybean stem fly represents a risk for major soybean‐producing countries, using Brazil as an example. Our analyses suggest that M. sojae has expanded its niche to new environments. Suitable habitats were predicted in all continents, including regions where this species has not yet been reported. Several soybean‐producing countries and all Brazilian growing areas are within the suitable ranges estimated for M. sojae. Also, most areas estimated as suitable under current climate conditions will remain so until at least 2080. These findings are important for invasion risk assessments aiming to prevent the spread of this species to major soybean‐producing areas.

A field experiment on the seasonal incidence of stem fly, Melanagromyza sojae (Zehntner) infesting black gram was carried out in variety GU 1 (Gujarat Urd 1) during kharif 2017 and 2021 at Entomology farm, B. A. College of Agriculture, AAU, Anand. Infestation of M. sojaewas observed from 1st WAS i.e., 34th SMW. Later on, infestation increased gradually and its highest infestation was observed during the 39th SMW i.e., 68.33 and 73.33% of kharif, 2017 and 2021, respectively. Stem fly infestation exhibited a highly significant positive association (r = 0.519** and 0.655**, respectively) with bright sunshine hours (BSS) and maximum temperature (MaxT), respectively. Abiotic factors viz., rainfall (RF) exhibited a significant negative association (-0.458*), while evaporation (EP) showed a significant positive association (0.466*).
