Accumulation of endogenous and exogenous toxins in patients with chronic kidney disease increases thekidney burden. The newly developed plasma separation adsorption membranes provide a new model forthe removal of middle molecular toxins. In this study, the adsorption resin LX-1000H is physically pulverizedand blended into polyethersulfone matrixes to prepare adsorption resin/polyethersulfone (AR/PES) membranes by nonsolvent-induced phase separation for plasma separation and middle moleculartoxins absorption. The results show that the static adsorption capacity of AR/PES membrane for lysozyme(a typical mimic of middle molecular toxins) is up to 108.90 mg/g, which is 4 times that of AR. The maximumdynamic adsorption capacity reaches 102.80 mg/g, which is 93.4% of static adsorption. The adsorptionprocess is more consistent with the Langmuir model and the quasi-first-order kinetic model. Thepermeability of bovine serum albumin in simulated blood surpasses 90% and the cattle blood separatedby AR/PES membrane is colorless and transparent. The AR/PES membrane surface presents electronegativeat pH 7.4 and the water wettability is enhanced with the doping amount. No hemolysis and negligibleleakage indicated favorable hemocompatibility. This paper is devoted to providing a strategy forplasma separation and adsorption membranes.

The fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), is a major maize pest worldwide and has caused huge economic loss. To explore the control tactics of S. frugiperda in mountain maize planting fields, studies were performed in China from 2020 to 2021 for screening the S. frugiperda-resistant maize variety, seed coating agents, chemical insecticides, and biological agents. The results showed that 75 g/hm 2 Emamectin benzoate had better controlling efficacy (with a control efficacy of 91.05% at 1d) than other chemicals, so it was recommended in the high incidence period of pests. Compared with other seed coating treatments, 50% Lumi ngwei TM625FS (with a control efficacy of 76.19% at 10d) was the best seed coating against S. frugiperda. The biological control “Telenomus remus + Picromerus lewisi” and “T. remus + Eocanthecona furcellata” had good control efficacy on S. frugiperda with 76.01%, 64.10% at 20d, respectively. Additionally, there were lower numbers of S. frugiperda in maize variety GuiDan6, BaoYu9, and YanBaiYu8. In summary, this research rec ommended four effective pest management strategies (GuiDan6-resistant maize variety, 50% Lumingwei TM625FS-seed coating agents, 5% emamectin benzoate-chemical pesticide, and “T. remus + P. lewisi”-biological control) in mountain maize planting fields. The study provided effective control strategies for
