Pesticide resistance and resurgence are serious problems often occurring simultaneously in the field.In our long-term study of a fenpropathrin-resistant strain of Tetranychus cinnabaribus,enhancement of detoxification and modified fecundity mechanisms were both observed.Here we investigate the network across these two mechanisms and find a key node between resistance and resurgence.We show that the ecdysone pathway is involved in regulating the fecundity of T.cinnabaribus.The concentration change of ecdysone is consistent with the fecundity curve;the concentration of ecdysone is higher in the fenpropathrin-resistant strain which has stronger fecundity.The enhancement of ecdysone is due to overexpression of two P450 genes(CYP314A1 and CYP315A1)in the ecdysone synthesis pathway.Silencing expression of these CYP genes resulted in lower concentration of ecdysone,reduced expression of vitellogenin,and reduced fecundity of T.cinnabaribus.The expression of CYP315A1 is regulated by transcription factors Cap-n-collar isoform C(CncC)and Musculoaponeurotic fibrosarcoma protein(Maf),which are involved in regulating other P450 genes functioning in detoxification of fenpropathrin in T.cinnabaribus.A similar regulation is established in citrus pest mite Panonychus citri showing that the CncC pathway regulates expression of PcCYP315Al,which affects mite fecundity.Transcription factors are activated to upregulate detoxification genes facilitating pesticide resistance,while the“one to multiple”regulation mode of transcription factors simultaneously increases expression of metabolic enzyme genes in hormone pathways and alters the physiology of pests.This is an important response of arthropods to pesticides which leads to resistance and population resurgence.

Dengue is still a substantial vector-borne viral disease threat and burden of public health importance worldwide.This situation is complicated by dengue virus unprecedented resurgence and persistence of varied serotypes in endemic-prone areas,and man-made and natural activities consequences that promote vector emergence,transmission dynamics and spread across the Asia-Pacific region.There is an urgent need to strengthen operational and contextual surveillance-response research in improving early detection of active reservoir detection,novel drug in case management and quality evidence-based response including the deployment of dengue mass vaccination.Moreover,sustained mapping and watching of dengue risk factors or determinants,performance and outcome indicators of control or elimination programs effectiveness in defining minimum effective data towards community knowledge-based decision-making policy and effective response packages is imperative.Moreover,implementation of a robust,integrated dengue early warning surveillance,monitoring and response systems metrics is required for evidence-based,timely and cost-effective contextual mitigation strategies,and innovative interventions.

Breast Imaging Experiences at Academic Medical Centers during COVID-19: Restructuring, Reopening, and Preparing for Possible resurgence

Severe acute respiratory syndrome coronavirus 2 has thoroughly reshaped the medical landscape. Much has been written and discussed of the adaptations required by this pandemic, particularly in the realm of elective medical care. While some areas of the country have, in recent weeks, seen a plateau or even a decrease in coronavirus 2019 case-burden, others remain face-to-face with significant ongoing morbidity and mortality. Furthermore, given eased restrictions across numerous states and municipalities, a widespread resurgence of the disease is not precluded. To that end, we have attempted to summarize experiences and best practices in the handling of breast imaging against the backdrop of the novel coronavirus, and we consider future directions.

Conservation of natural enemy fauna in citrus canopies by horticultural mineral oil： Comparison with effects of carbaryl and methidathion treatments for control of armored scales

引用

Insect Science 2010年第5期17卷 414-426页

作者： Weiguang Liang Alan Meats G. Andrew C. Beattie Robert Spooner-Hartt Laura Jiang Centre for Plant and Food Sciences University of Western Sydney School of Biological Sciences University of Sydney Sydney New South Wales Austrafia

The disruptive effects of an nC24 horticultural mineral oil （HMO） and two other insecticides （carbaryl and methidathion） on two armored scale insects and natural enemy fauna were evaluated in two citrus orchards. In the first orchard, all three spray treatments and non-sprayed controls were distributed separately among individual trees in one block, whereas in the second orchard the control, HMO and methidathion treatments were applied at the level of whole blocks. The results in both orchards were similar. All three of the spray treatments had a lethal effect on the red scale insects and the effects of HMO and methidathion tested at the second site lasted for at least 19 weeks and for purple scale, at least 50 weeks. HMO did not have a significant effect on the abundance and species diversity of parasitoids and （for the most part） did not affect coccinellids and predatory mites. Both carbaryl and methidathion caused significant ongoing disruption to the above groups. No treatment resulted in the resurgence of the scale insects or the outbreak ofphytophagous mites, even where whole blocks were sprayed.

Containment Problem for Quasi Star Configurations of Points in P^2

Algebra Colloquium 2018年第4期25卷 661-670页

作者： Hassan Haghighi Mohammad Mosakhani Faculty of Mathematics K.N.Toosi University of TechnologyTehranIran

In this paper,the containment problem for the defining ideal of a special type of zero-dimensional subscheme of P^2,the so-called quasi star configuration,is investigated.Some sharp bounds for the resurgence of these types of ideals are given.As an application of this result,for every real number 0resurgences lie in the interval[2-ε,2).Moreover,the Castelnuovo-Mumford regularity of all ordinary powers of defining ideal of quasi star configurations are determined.In particular,it is shown that all of these ordinary powers have a linear resolution.

北方乡村呈现的民间宗教在乡村的复兴不是简单的政府与民众博弈的结果，而是各种社会力量、文化历史资源相互影响形成的一个非常复杂的过程。在这个过程中，乡村原有的自治传统得到了相对的恢复，各种民间传统文化资源的价值也不断受到各方面的关注。本文根据作者在田野调查研究和其他学者对乡村民间宗教恢复的研究，来观察在北方农村各地方具有普遍性的民间宗教现象是如何逐渐地获得存在合法性的。由于民间毫不张扬的努力，以乡土中国为核心的价值和信仰重新进入了人们的视野，不仅仅再次成为民间生活的一部分，同时为在过去一百多年由于自身价值失落，而备受困扰的中国找到了一条值得探讨的途径。
