“…The XRD results of the reduced samples are shown Figure 7. The main phases in all the reduced samples were metallic iron and (Fe, Mg)Ti 2 O 5 , which agreed with a previous study11 and calculation. The intensity of metal iron significantly increased with increasing Fe–Si amount or reduction time, which corresponds to the metallization ratio of iron in the reduced samples shown in Figure 4.…”

The particle size and metallization ratio of iron in reduced ilmenite have an important function in separating the metal from TiO 2 -rich slag in the electric arc furnace process. In this study, an ilmenite concentrate supplied by Panzhihua Iron and Steel (Group) Co. was reduced at 13808C in an electric resistance furnace. The effects of Fe-Si addition and reduction time on the particle size and metallization ratio of iron in the reduced sample were analyzed. The metallization ratio of iron significantly increased with increasing Fe-Si amount and reduction time, and reached %90% after 40 min. However, the metallization ratio of iron was about 85% without Fe-Si addition. Meanwhile, the iron particle size increased with increasing Fe-Si amount; the growth was obvious with the addition of 1% Fe-Si. Moreover, the growth rate of the iron particle size also increased with increasing reduction time. The TG-DTG curves indicated that the mass loss with Fe-Si addition was less than that without Fe-Si addition, and the temperature at which the maximum rate of mass loss rate was achieved was lower than that without Fe-Si addition.

“…Studies have shown that the damage caused by high temperatures to insects is irreversible and has a certain accumulative effect. Exposure to high temperatures for a long time will lead to a significant decrease in the water content of insects and even their death (Zhong, 2010;Zhang et al, 2014). Investigating the effects of high temperature on the mortality and activity behaviour of D. citri demonstrated that a high temperature above 40°C leads to a decrease in the survival time of the D. citri population (Kuang et al, 2017).…”

Peer Review #1 of "Predicting the potential distribution of the Asian citrus psyllid, Diaphorina citri (Kuwayama), in China using the MaxEnt model (v0.1)"

Background. Citrus huanglongbing (HLB) is a destructive disease of citrus and a major threat to the citrus industry around the world. This disease accounts for substantial economic losses in China every year. Diaphorina citri Kuwayama is one of the major vectors by which citrus HLB is spread under natural conditions in China. Research is needed to identify the geographic distribution of D. citri and its major areas of occurrence and to formulate measures for early warning, monitoring and control of this pest and citrus HLB. Methods. In this study, the ecological niche modelling software MaxEnt (maximum entropy model) was combined with ArcGIS (a geographic information system) to predict the potential geographic distribution of D. citri in China. Key environmental factors and the appropriate ranges of their values were also investigated. Results. Our results show that the training data provided a good forecast (AUC mean = 0.988). The highly suitable areas for D. citri in China are mainly concentrated to the south of the Yangtze River, and the total area is 139.83×10 4 km 2. The area of the moderately suitable areas is 27.71×10 4 km 2 , with a narrower distribution than that of the highly suitable area. The important environmental factors affecting the distribution of D. citri were Min Temperature of Coldest Month, Mean Temperature of Coldest Quarter, Precipitation of Wettest Quarter, Mean Temperature of Warmest Quarter, Precipitation of Warmest Quarter, Max Temperature of Warmest Month, and Temperature Seasonality. These results provide a valuable theoretical basis for risk assessments and control of D. citri. Discussion. The predicted results showed that there were highly suitable areas for D. citri in Chongqing, Hubei, Anhui and Jiangsu. Therefore, the possibility exists for the further spread of D. citri in China in the future. Extreme temperature variables, especially the Min temperature of the coldest month, play an important role in the distribution of D. citri and are most closely related to the distribution of D. citri.
