functional response of a solitary, larval-pupal endoparasitoid of Liriomyza leafminers, Ganaspidium utilis Beardsley, was estimated on Liriomyza trifolii Burgess at three temperatures （17℃, 25℃, 29℃ ） and host densities. A type Ⅱ random parasitoid equation （RPE） was used to estimate instantaneous search rate and handling time. The instantaneous search rate increased as temperature increased. All of the RPE regressions obtained for functional response of G. utilis at different temperatures were significant （P〈0.01）. The slope of RPE regression lines was lower across the temperatures. At 29±2℃, the maximum number of larvae parasitized was 7.8 per day. It decreased to 7.2 larvae parasitized at 25±2℃. At 17±2℃, no significant increment of parasitization was observed due to the host density increments. The estimated handling time was lowest at 17±2℃ and highest at 25 ± 2℃, respectively. The ability of G. utilis to find and parasitize L. trifolii over a wide range of temperatures makes them a good candidate for biological control of Liriomyza leafminers.

遥感图像目标检测是目标检测领域的一个关键问题,目前利用深度学习检测目标的算法大多在单向特征融合过程中添加注意力机制,一视同仁地去增强各类型的目标,并不能突出小目标。为了取得更好的检测效果,通过引入非对称高低层调制机制,构造兼顾低层细节信息和高层语义信息的特征图,以达到增强小目标特征检测的目的;同时使用DIoU损失函数代替原算法SmoothL1损失函数以提升算法检测精度与收敛速度;并且在感兴趣区域分类任务中引入灵活上下文信息以提高小目标分类准确性。实验结果表明,该算法在DIOR和NWPU VHR-10数据集上均取得了良好的表现。

为探究达拉特旗黄河南岸灌区向日葵根系吸水来源及其利用策略,通过测定达拉特旗黄河南岸灌区向日葵木质部水及其各种潜在水源(降水、土壤水和地下水)的氢氧同位素组成(δD和δ18O),利用直接对比法和MixSIAR模型研究对比不同灌溉制度下向日葵不同生育期水分来源及各水源利用差异。结果表明,向日葵在苗期、拔节期、灌浆期和成熟期的吸水深度分别在0~30、0~50、0~70和30~90 cm土层。不同灌溉量下,向日葵的主要吸水层具有一定的差异。0~10、10~30、30~50、50~70、70~90 cm深度土壤水和地下水对向日葵平均贡献比例分别为22.17%、17.99%、18.74%、14.68%、15.97%和10.45%。通过相关性分析,50 cm以下土层水分贡献对产量提高有利,0~10 cm土壤水、30~50 cm土壤水和地下水利用对灌溉水利用效率具有正相关关系。设置灌溉定额为187.5 mm时能显著提高产量,灌溉定额为100 mm时,能显著提升灌溉水利用效率。

This paper proposes a systematic method, integrating the uniform design (UD) of experiments and quantum-behaved particle swarm optimization (QPSO), to solve the problem of a robust design for a railway vehicle suspension system. Based on the new nonlinear creep model derived from combining Hertz contact theory, Kalker's linear theory and a heuristic nonlinear creep model, the modeling and dynamic analysis of a 24 degree-of-freedom railway vehicle system were investigated. The Lyapunov indirect method was used to examine the effects of suspension parameters, wheel conicities and wheel rolling radii on critical hunting speeds. Generally, the critical hunting speeds of a vehicle system resulting from worn wheels with different wheel rolling radii are lower than those of a vehicle system having original wheels without different wheel rolling radii. Because of worn wheels, the critical hunting speed of a running railway vehicle substantially declines over the long term. For safety reasons, it is necessary to design the suspension system parameters to increase the robustness of the system and decrease the sensitive of wheel noises. By applying UD and QPSO, the nominal-the-best signal-to-noise ratio of the system was increased from -48.17 to -34.05 dB. The rate of improvement was 29.31%. This study has demonstrated that the integration of UD and QPSO can successfully reveal the optimal solution of suspension parameters for solving the robust design problem of a railway vehicle suspension system.
