随着新的媒介种类的出现和现存种类的种群增长,蚊虫及其传播疾病仍然是人类主要的公共卫生危害之一。由于缺乏疫苗以及有效的药物治疗,防控蚊媒病唯一可持续的关键措施是蚊虫控制。相较于控制成蚊,使用灭幼剂控制蚊虫孳生地更为有效可行。但目前可用的灭幼剂为数不多。这些可用的灭幼剂主要包括微生物制剂、昆虫生长调节剂和其他选项(比如植物源杀虫剂)。在昆虫生长调节剂领域,保幼激素模拟物在研发和使用领域均受到了广泛关注。吡丙醚于20世纪70年代早期由日本住友化学首次合成,其潜在杀虫作用和安全性已在很多有害节肢动物的控制上得到充分认可。本次述评介绍了吡丙醚的一般信息,并重点强调其以下优势:独特的模拟天然保幼激素活性的作用机理,广泛的靶生物谱,与其他所有已知的或者潜在的灭幼剂相比具有较高的生物活性,很低的抗性风险,不易产生交叉抗性,而且对覆蚊亚属有很高的杀灭活性。由于吡丙醚能影响成蚊生殖和寿命而越来越多地被尝试用于饵剂,绿篱喷洒以及蚊帐处理来杀灭成蚊。吡丙醚和其代谢物在环境中的残留和潜在影响,值得进一步评估。无论是现在或可预见的将来吡丙醚在蚊虫控制上都是一个不可或缺的重要工具。

尽管节肢动物类(主要指昆虫纲和蛛形纲)病媒和害虫的综合治理取得了较大进展,但其对公共卫生及人类健康仍造成巨大威胁,且这种情形随着全球化、城市化和常规杀虫剂滥用以及抗药性的发展变得更加严峻。有机氯类、有机磷类、氨基甲酸酯类和拟除虫菊酯类常规杀虫剂在历史上对保护人类和动物免于病媒生物和其他城市害虫的侵害起着重要作用,但这些杀虫剂对环境和非靶标生物的不良影响在全球范围内也越来越受到关注。20世纪70年代以来,随着对节肢动物生物学的深入了解,基于昆虫生长调节剂的软性杀虫剂的研发受到了极大的重视。传统杀虫剂因具有易获得和见效快等优点已被使用者和公众广泛接受,软性杀虫剂的研发经历曲折。然而,基于昆虫激素类似物、模拟物或者激动剂以及几丁质合成抑制剂的软性杀虫剂在很多方面也取得了长足的进展。软性杀虫剂中发展和使用最成功的案例是保幼激素类似物(比如烯虫酯、烯虫乙酯和烯虫炔酯),已经应用于多种病媒生物和环境害虫的治理。最近,S-烯虫酸叔丁酯的诞生又带来了新的成功机遇。保幼激素模拟物吡丙醚和苯氧威因在病媒生物和其他害虫治理中具有显著的应用价值也得到了较好的研究和开发。保幼肽因其生物活性和作为多肽可以预期的环境安全性,近年来再次引起人们的关注。相比保幼激素类似物,蜕皮激素受体激动剂对靶标生物具有更宽的敏感窗口期,研发潜力巨大。几丁质合成抑制剂因其作用方式独特和杀虫谱广而备受重视。总之,不管软性杀虫剂单独使用,还是与传统杀虫剂联合使用,在不久的未来都将在病媒生物及其他城市害虫的治理方面发挥重要作用。

In this short note, we report the ages of five lava samples from a segment of the Eastern Lau Spreading Center （ELSC） and three samples from the Valu Fa Ridge （VFR） in the southern Lau Basin. These samples were collected in situ from the axes and flanks of the spreading centers in the basin. These ages provide a key to better understanding the spreading mode, crustal formation and overall tectonic evolution of the basin. Except for two basaltic andesites and one andesite, the lavas analyzed are basalts. The ages of the lavas from ELSC range from （1.45±0.15） Ma to （0.74±0.04） Ma whereas those from VFR range from （0.50±0.06） Ma to （0.32±0.27） Ma, and the basalts give the oldest ages. The relatively younger ages of the VFR lavas are consistent with proposed tectonic evolution of the southern Lau Basin, i.e., VFR is a propagating extension of ELSC. The occurence of older lavas close to or on spreading axes in the southern Lau Basin implies the complex tectonic evolution of the basin. These results underscore a need for further detailed geophysical and geological studies in the southern Lau Basin, in order to better clarify the crustal accretion tectonic evolution in this area.

The process of mass movements and their consequent turbidity currents in large submarine canyons has been widely reported, however, little attention was paid to that in small canyons. In this paper, we document mass movements in small submarine canyons in the northeast of Baiyun deepwater area, north of the South China Sea （SCS）, and their strong effects on the evolution of the canyons based on geophysical data. submarine canyons in the study area arrange closely below the shelf break zone which was at the depth of -500 m. Within submarine canyons, seabed surface was covered with amounts of failure scars resulted from past small-sized landslides. A complex process of mass transportation in the canyons is indicated by three directions of mass movements. Recent mass movement deposits in the canyons exhibit translucent reflections or parallel reflections which represent the brittle deformation and the plastic deformation, respectively. The area of most landslides in the canyons is less than 3 km2. The trigger mechanisms for mass movements in the study area are gravitational overloading, slope angle and weak properties of soil. Geophysical data indicate that the genesis of submarine canyons is the erosion of mass movements and consequent turbidity currents. The significant effects of mass movements on canyon are incision and sediment transportation at the erosion phases and fillings supply at the fill phases. This research will be helpful for the geological risk assessments and understanding the sediment transportation in the northern margin of the SCS.

Based on the ArcGIS geographic information system and the ORACLE database management system,this paper reports our studies on the technology of Marine Engineering Geological Exploration Information System(MEGEIS). By analyzing system structure,designing function modules and discussing data management,this paper systematically proposes a framework of technol-ogy to integrate,manage,and analyze the seabed information comprehensively. Then,the technology is applied to the design and development of the Bohai Sea Oilfield Paradigm Area Information System. The system can not only meet the practical demands of marine resources exploration and exploitation in the Bohai Sea oilfield,but also serve as a preparatory work in theory and technology for the realization of the 'Digital Seabed'.
