Citrus leprosis (CL), caused by the Citrus leprosis virus C (CiLV-C), is considered to be one of the most destructive plant diseases, especially for sweet orange [Citrus sinensis (L.) Osbeck]. To date, it has been restricted to the American continent. Its presence has been confirmed from Argentina to Mexico (Rodrigues et al., 2003; Bastianel et al., 2010; Izquierdo-Castillo et al., 2011). CL was originally described in Florida, in the USA, in the early 1900s (Fawcett, 1911). However, the disease appears to have disappeared from Florida since the 1960s (Childers et al., 2003). There is evidence that leprosis in Florida was caused by Citrus leprosis virus N (CiLV-N) (Kitajima et al., 2011), a distinct virus, possibly related to the Orchid fleck virus (OFV) (Kondo et al., 2006), which appears to be less aggressive. CiLV-C is transmitted by the tenuipalpid mite Brevipalpus, and B. phoenicis Geijskes is the species most commonly described as the vector (Bastianel et al., 2010). The available evidence suggests that the virus-vector. |

Brazil has extensive pasture areas for beef cattle grazing. An experiment was carried out in summer in a Brachiaria pasture in Southeastern Brazil, characterized by hot and humid climate in summer and dry in winter, with the objective of measuring hourly fluxes of methane and nitrous oxide from soil and identifying a possible relationship with environmental parameters, including air temperature, soil temperature, solar radiation, photosynthetically active radiation (PAR), and soil moisture. Temperature and radiation data were obtained from a climatological station on February 13 and 14, 2020, starting at 9:00 am and ending at the same hour of the next day. Soil moisture data were recorded by humidity sensors. The gas collection method used was the static closed chamber. Five chambers were used at the same time. Methane and nitrous oxide concentrations were sampled every 2 hours, in intervals of 0, 10, 20, 30, and 40 minutes. The gas samples were extracted by BD 60 mL syringes with a three-way luer lock valve and then transferred to 12 mL vacuum vials of the Labco Exetainer brand. A Thermo Scientific chromatograph model, Trace 1310, was used to determine the concentrations of gases. The statistical analysis was performed using the PROC CORR procedure of the SAS program. Preliminary results showed that N2O fluxes peaked at 3 p.m. with around 10 ?g N-N2O m-2 h-1 and a minimum value of -2 ?g N-N2O m-2 h-1 at 1 a.m. N2O fluxes were positively correlated with air temperature (0.70939 /0.0066) and with PAR (0.59037/0.0337), while they were negatively correlated with relative humidity (-.69266/0.0087). Methane correlated negatively with soil temperature (-0.88646/<0.001), although the concentrations were very low throughout the day. Other diel measurements are going to be carried out and the experiment will be repeated in the summer season. MenosBrazil has extensive pasture areas for beef cattle grazing.
