Abstract
This article aims to increase the knowledge of the roles and functions of public health institutes (PHIs) by exploring and comparing the Scandinavian PHIs, their roots, and developments over time. The research questions are the following: What was the history behind these public institutions? How have they changed over time? Have they followed divergent or parallel paths of change? How, if at all, have they been influenced by public sector reforms? Comparing the three Scandinavian countries based on an institutionalist approach, the article seeks to increase the understanding of the role of PHIs in governing public health. The article is based on documents from parliaments and governments from the public health institutes, supplemented by institution narratives and relevant public health and public administration literature. The Scandinavian PHIs have common roots from the early 1900s, have followed different routes, and have different institutional characteristics and different roles as public health institutions. However, after more than 100 years, the Scandinavian PHIs belong to the international PHI organization. They are responsible for knowledge dissemination, surveillance, and preparedness for the handling of epidemics and pandemics. The article argues for more comparative research on institutions related to public health authorities, such as the PHIs.

The fall armyworm, Spodoptera frugiperda, situation in Africa remains a priority threat despite significant efforts made since the first outbreaks in 2016 to control the pest and thereby reduce yield losses. Field surveys in Benin and Mali reported that approximately one-week post-emergence of maize plants, the presence of fall armyworm (egg/neonates) could be observed in the field. Scouting for fall armyworm eggs and neonates is, however, difficult and time consuming. In this study, we therefore hypothesized that the optimum timeframe for the fall armyworm female arriving to lay eggs in sown maize fields could be predicted. We did this by back-calculating from interval censored data of egg and neonates collected in emerging maize seedlings at young leaf developmental stage. Early time of ovipositing fall armyworm after sowing was recorded in field experiments. By using temperature-based models to predict phenological development for maize and fall armyworm, combined with analytical approaches for time-to-event data with censored status, we estimated that about 210 accumulated Degree Days (DD) is needed for early detection of neonate larvae in the field. This work is meant to provide new insights on timely pest detection and to guide for precise timing of control measures.

Invasive pests and plant pathogens pose a significant threat to ecosystems and economies worldwide, prompting the need of anticipatory strategies. Preventing their introduction by detection at the ports of entry has been proven extremely difficult. This review explores the potential of biogenic volatile detection as a reliable preventive solution. It underscores the importance of early detection and rapid response as integral components of effective invasive pest management, and it discusses the limitations of current control measures and the increasing globalization that facilitates the spread of pests and pathogens. Through a synthesis of existing literature, this review analyzes the Volatile Organic Compound (VOC) emissions in five invasive model species: three insects, Halyomorpha halys, Spodoptera frugiperda, Helicoverpa armigera, a nematode, Bursaphelenchus xylophilus, and an oomycete, Phytophthora ramorum. The review focuses on the specific volatiles, released by both the invasive organisms and the infested host plants. If available, the volatiles emitted from similar species were considered for comparison. Ultimately, this review highlights specific pest volatile and shared Herbivore Induced Plant Volatiles (HIPVs) as a reliable and innovative solution in pest detection. If possible, candidate compounds are provided, whilst the lack of some emphasizes the urge of expanding the information available.
