Dendroctonus valens LeConte, an invasive forestry pest, is highly dependent on its olfactory system for vector-related activities such as host seeking, oviposition and population aggregation. The antennae are the primary olfactory organs in bark beetles. We describe 4 morphological types of sensilla on the antenna of D. valens: 1) 3 types of sensilla trichodea located at the apex and lateral surface of the club and innervated by 5, 0, 13 dendrites, respectively. 2) sensilla chaetica found on the the scape and funicle and innervated by 7 dendrites. 3) a pair of sensilla basiconica distributed almost on the three sensory bands innervated by 2 dendrites at the base, and 4) one flunted cone type of grooved peg dispersed throughout the sensory bands, but its ultrastructure was not investigated. The possible functions of these sensilla were discussed in relation to their morphology and the ultrastructure of four types of antennal sensilla.

中国式现代化是人与自然和谐共生的现代化。伴随中国式现代化向纵深推进,跨域环境治理在复杂的主体利益关系模式下表征为圈层嵌套式的差等网络结构与级序行动逻辑,即差序协同模式。从环境污染正在经历的由局部向广域转变的解域化过程来看,差序协同既源自于跨域环境治理知识生产者与接受者的分离,又归因于权力结构内部权力主客体的互动关系。受此影响,跨域环境治理极易陷入过密治理与试点空转以及制度悬浮与行为失调的藩篱与窠臼,由此阻碍“制度—效能”转化,以致“局部有效而整体失效”“有组织的不负责任”样态此起彼伏。为达到“收放自如,进退裕如”的国家治理高度,就我国跨域环境治理体系而言,我们应将政府、市场与社会视为一个抽象的连续体,并以链式思维消解行政替代困境和自治缺位困境。

The fate of arsenic in natural environments is influenced by adsorption onto metal （hydr）oxides. The extent of arsenic adsorption is strongly affected by coexisting dissolved natural organic acids. Recently, some studies reported that there existed competitive adsorption between arsenate and citrate on goethite. Humic acid is known to interact strongly with arsenate by forming complexes in aqueous solution, hence it is necessary to undertake a comprehensive study of the adsorption of arsenate/citrate onto goethite in the presence of one another. The results showed that at the arsenate concentrations used in this study （0.006-0.27 mmol/L）, citrate decreased arsenate adsorption at acidic pH but no effect was observed at alkaline pH. In comparison, citrate adsorption was inhibited at acidic pH, but enhanced at alkaline pH by arsenate. This was probably due to the formation of complex between arsenate and citrate like the case of arsenate with humic acid. These results implied that the mechanism of the adsorption of arsenate and citrate onto goethite in the presence of one another involved not only competition for binding sites, but the cooperation between the two species at the watergoethite interface as well.

This study was conducted on the desert riparian forest along the lower reach of the inland Tarim River, which is located in the arid region of Northwest *** plant species in 10 families were collected from five monitoring sections,and examined for the infection of arbuscular mycorrhizal fungi (AMF). The impact of different soil factors on AMF infection rate and intensity was compared using the principal component analysis (PCA) method. The results indicate that 11 species are AM and only 4 are non-AM plants. The estimated capacity of AMF infection depends on families of plants and also the parameters (infection rate, infection intensity, fungal spore density) used. The density of fungal spores was relatively higher in Phragmites communis and Populus euphratica in Graminaceae and Salicaceae families, *** infection rate was above 50%in all the AM plants,except Calligonum *** highest infection rate appeared in Alhagi sparsifolia (97%) and Glycyrrhiza inflata (92%). However, when compared by AMF infection intensity, Tamarix spp. became the top one, followed by Alhagi sparsifolia, and Glycyrrhiza inflata was in the middle range of all the species. The PCA has identified that soil total salt, moisture, organic matter, total nitrogen, total P, available K and pH were closely associated with the AMF infection.
