BACKGROUND: The brown marmorated stink bug (BMSB), Halyomorpha halys, has caused significant agricultural damage to numerous hosts, so agricultural producers seek to limit its spread. Where established, BMSB can also cause substantial urban and commercial disturbance, as overwintering adults may seek refuge inside dwellings, covered spaces, vehicles, and consignments. Phytosanitary authorities are most concerned with the importation of 'hitchhiking' adults in this refugia, with certain countries requiring a quarantine treatment to mitigate risk. This study explores fumigation with ethyl formate, applied as 16.7% by mass dilution in carbon dioxide, for control of adult BMSB. RESULTS: The induction of diapause, to simulate overwintering physiology, resulted in 2‐ and 3‐fold increases in the tolerance of adults toward this ethyl formate fumigation at 10 ± 0.5 °C (x¯±2s) lasting for 8 and 12 h, respectively. However, a decreased tolerance (0.7‐fold) of diapausing specimens was observed for a 4‐h duration. Diapausing and nondiapausing adult BMSB can be controlled at the probit 9 level if the headspace concentration of ethyl formate, [EF], in the carbon dioxide mixture is maintained ≥7.68 mg L−1 for 12 h at 10 ± 0.5 °C (x¯±2s). If the duration is shortened to 4 h, [EF] must be maintained ≥14.73 mg L−1 over the course of fumigation. CONCLUSION: The toxicity of ethyl formate in this mixture can be distinct for different physiological states of the same life stage, as evidenced by a ca. 3‐fold increase in the Haber's z parameter for adult BMSB when in diapause. Respective to the physiological state of adults, this study identifies how the applied dose and/or treatment duration can be modulated (i.e. tuned) to ensure adequate toxicological efficacy toward BMSB infesting hosts or refuge at temperatures ca. >10 °C.

It has long been known that there is a special affinity of psoriasis for the scalp: Here, it occurs most frequently, lesions terminate sharply in frontal skin beyond the hair line and are difficult to treat. Yet, surprisingly, scalp psoriasis only rarely causes alopecia, even though the pilosebaceous unit clearly is affected. Here, we systematically explore the peculiar, insufficiently investigated connection between psoriasis and growing (anagen) terminal scalp hair follicles (HFs), with emphasis on shared regulatory mechanism and therapeutic targets. Interestingly, several drugs and stressors that can trigger/aggravate psoriasis can inhibit hair growth (e.g. beta‐blockers, chloroquine, carbamazepine, interferon‐alpha, perceived stress). Instead, several anti‐psoriatic agents can stimulate hair growth (e.g. cyclosporine, glucocorticoids, dithranol, UV irradiation), while skin/HF trauma (Köbner phenomenon/depilation) favours the development of psoriatic lesions and induces anagen in "quiescent" (telogen) HFs. On this basis, we propose two interconnected working models: (a) the existence of a bidirectional "hair follicle‐psoriasis axis," along which keratinocytes of anagen scalp HFs secrete signals that favour the development and maintenance of psoriatic scalp lesions and respond to signals from these lesions, and (b) that anagen induction and psoriatic lesions share molecular "switch‐on" mechanisms, which invite pharmacological targeting, once identified. Therefore, we advocate a novel, cross‐fertilizing and integrative approach to psoriasis and hair research that systematically characterizes the "HF‐psoriasis axis," focused on identification and therapeutic targeting of selected, shared signalling pathways in the future management of both, psoriasis and hair growth disorders.

- Abstract
Stored commodities are man-made ecosystems and interactions of biological agents with its surrounding physical environment could result in significant economic losses if physical environment is not manipulated to make it lethal or at least difficult for survival of biological agents. Control and Management of Pests in Stored Products is based on 18 invited presentations by world-renowned experts on topics of relevance to control and manage pests in stored products. Each chapter synthesizes the state-of-art knowledge on the selected topics dealing with fumigation, fumigants, and other methods of controlling insects such as low temperature, diatomaceous earth, integrated pest management and provides recommendations for future research. It also includes two chapters on practical aspects of fumigation dealing with engineering considerations and safety. The contents of the chapters were presented as the keynote addresses at the International Conference on Controlled Atmosphere and Fumigation in Stored Products.This book serves as a reference book for graduate students, researchers, and facility managers, and can also be useful as a textbook for courses dealing with aspects of grain storage for students in agricultural engineering, agricultural entomology and food science.

- Abstract
Encyclopedia of Toxicology, Fourth Edition is the most extensive compendium surveying the full scope of toxicology, including its chemical, biological and physical (e.g., radiation) perspectives. Spanning nine volumes, this new edition comprises 1150 thoroughly revised and 70 entirely new entries authored by experts in their respective fields, selected by a globally recognized board who have brought rigorous editorial skills to the project. New areas covered in this release include the bourgeoning field of computational toxicology, research applications of alternatives to animal testing, the rise in development and use of consumer products and their effects on populations, and the increasing introduction and use of pharmaceutical ingredients and their interactions. Other chapters of note cover artificial intelligence models of toxicological exposure and effects, extractables and leachable testing, climate change implications for humans, animals and the environment, screening models, -omics, tools such as sequence alignment to predict across species susceptibility, and much more. - Includes contributions from a world-renowned editorial board and expert contributors with wide-ranging backgrounds in toxicology - Thoroughly updated with the latest advances in the science - Contains concise and accessible content, providing an authoritative reference resource for non-specialists and readers from undergraduate level upwards, as well as advanced healthcare providers - Covers new topics such as computational toxicology, alternatives to animal testing, pharmaceutical ingredients, artificial intelligence models of toxicological exposure and effects, wildfires and effects of their smoke, vaping, high throughput transcriptomics, and the effect of environmental chemicals on the microbiome

- Abstract
This book explains the challenges for efficient sustainable surface and groundwater development and management with the focus on India and other countries, providing a stable output presentation by using machine learning data mining methods, and modeling. It is a combination of machine learning, modeling, google earth engine, climate data modeling, remote sensing and GIS techniques, surface water modeling, AHP modeling, groundwater quality analysis, aquifer mapping, land use and land cover analysis, forecasting of water and rainfall and so on, its use to sustainable development, planning, and management of groundwater purposes in India and other countries. The main purpose of this book will develop better outlines for the development of surface and groundwater and management in the semi-arid region climate, which supports the Sustainable Development Goals (SDGs) in India, especially on sustainable surface water and groundwater resources management. This book provides amultidisciplinary overview for the faculty members, administrators scientists, policymakers, social science, and professionals involved in the various aspects of sustainable groundwater development, planning, and management.
