The soybean rust caused by Phakopsora pachyrhizi is considered the main soybean disease and consequently the appropriate selection and the use of spraying equipment are vital for its control. The aim of this study was to evaluate the performance of aerial application equipment for soybean rust control. It was used: Micronair AU 5000 at 10 L ha-1 (with oil) and at 20 L ha-1 (without oil); Stol ARD atomizer at 10 and 20 L ha-1 (both with oil) and Spectrum (electrostatic) at 10 L ha-1 (without oil). The adjuvant was cotton oil (1.0 L ha-1) with emulsifier (BR 455) at 0.025 L ha-1. The field trial was set up at the 3rd fungicide application, when f four replications of each treatment. There were no statistical differences among treatments related to fungicide deposits by at a Confidence Interval of 95%. It was observed that the best results were obtained with Micronair (10 L ha-1 with oil), Stol (20 L ha-1 with oil) and electrostatic system at 10 L ha-1 with the lowest relative humidity (64%).

AbstractQuarantine insects are economically important pests that frequently invade new habitats. A rapid and accurate monitoring method to trace the geographical source of invaders is therefore needed for prevention, detection, and eradication. Current methods based on insect genetics are often too slow. We developed a novel tracing method based on insect gut microbiota. The source location of microbiota of insects can be used to rapidly determine the insects’ geographic origin. We analyzed 179 gut microbiota samples belonging to 591 individuals of 22 quarantine insect species collected from 36 regions in China and abroad. The gut microbiotas of these insects mainly included Actinobacteria, Bacteroidetes, Cyanobacteria, Firmicutes, Proteobacteria, and Tenericutes. The diversity of the insect gut microbiota was closely related to geographic and environmental factors. Different insect species could be distinguished at the phylum level of microbiota. Populations of individual insect species from different regions could be distinguished at the genus level of microbiota. A method for determining the geographical origin of invasive insect species was tentatively established, but its practical applicability requires further study.

A superhydrophobic and superoleophilic oil sorbent was prepared by attaching SiO2 particles onto a cotton fiber surface by a sol–gel method and subsequent octadecyltrichlorosilane modification.
