A revision of Dolichogenidea (Hymenoptera, Braconidae, Microgastrinae) with the second mediotergite broadly rectangular from Area de Conservación Guanacaste, Costa Rica
The first species of Dolichogenidea (Hymenoptera: Braconidae, Microgastrinae) with the second mediotergite broadly quadrate to rectangular are revised, and eight new species from Area de Conservación Guanacaste (ACG), Costa Rica are described, all authored by Fernandez-Triana & Boudreault: alejandromasisi, angelagonzalezae, carlosmanuelrodriguezi, genuarnunezi, josealfredohernandezi, melaniamunozae, rogerblancoi, and yeimycedenoae. A new species group (carlosmanuelrodriguezi) within the genus is proposed to accommodate those species, as well as additional undescribed species from the Neotropical region found in collections. All new species are found in rainforests (120–900 m) and all are parasitoids of Depressariidae (except for one species parasitizing Choreutidae). The unique shape of the second mediotergite and long ovipositor are features shared with the alejandromorai species group in the genus Apanteles, an example of convergent evolution; both wasp groups also parasitize similar hosts in ACG
Développement d'une échelle interdisciplinaire bilingue évaluant l'auto-efficacité à participer à l'aide médicale à mourir
Medical Assistance in Dying (MAiD) is a complex process involving the person seeking care and their relatives. MAiD involves physical, psychosocial and spiritual needs, and consequently the involvement of an interdisciplinary team is beneficial. Therefore, updating the knowledge and skills of healthcare and social services professionals is critical. An interdisciplinary team from Laval University (Quebec, Canada) has developed a continuous training program for all health care and social services professionals who could be involved in the care of persons who request MAiD and their loved ones. It is crucial to assess whether the objectives of the continuous training program are being met, especially since this new training addresses several complex issues (legal, ethical, and clinical). Bandura's self-efficacy theory has been widely used to develop scales for assessing the impact of training programs and identifying knowledge gaps. Bandura's theory states that feeling secure in one's self-efficacy leads to self-determined motivation. Although there are various scales intended to measure self-efficacy in palliative care, none include self-efficacy for participating in the process surrounding MAiD. As a result, we aim to create a bilingual (English-French) interdisciplinary scale to assess self-efficacy for participating in the process surrounding MAiD. The scale will allow decision-makers and researchers to identify current knowledge gaps. It will also be useful for assessing the impact of current and future training programs addressing this end-of-life practice. In this work in progress, we briefly introduce the training program and the future steps in the development and validation of the scale.L'aide médicale à mourir (AMM) est un processus complexe impliquant la personne qui demande le soin et ses proches. L'AMM implique des besoins physiques, psychosociaux et spirituels. Par conséquent, l'implication d'une équipe interdisciplinaire est bénéfique et la mise à niveau des connaissances et des compétences des professionnel.es est essentielle. Une équipe interdisciplinaire de l'Université Laval (Québec, Canada) a développé un programme de formation continue destiné aux professionnelles de la santé et des services sociaux susceptible d'être impliqué es dans ls soins et services des personnes qui demandent l’AMM et de leurs proches. Il est crucial d'évaluer si les objectifs du programme de formation continue sont atteints, d'autant plus que cette nouvelle formation aborde plusieurs questions complexes (juridiques, éthiques et cliniques). La théorie du sentiment d'auto efficacité de Bandura a été largement utilisée pour développer des échelles permettant d'évaluer l'impact des programmes de formation et d'identifier les lacunes en matière de connaissances. Cette théorie stipule que le fait de se sentir sûre de son efficacité personnelle conduit à une motivation intrinsèque à accomplir le comportement visé. Bien qu'il existe plusieurs échelles destinées à mesurer l'auto-efficacité dans le domaine des soins palliatifs, aucune n'inclut l'auto-efficacité pour la participation au processus entourant l’AMM. Par conséquent, nous développons une échelle interdisciplinaire bilingue (anglais-français) pour évaluer l'auto-efficacité à participer au processus entourant l’AMM. L'échelle permettra aux décideuses, décideurs et aux chercheuses et chercheurs d'identifier les lacunes actuelles en matière de connaissances. Elle sera également utile pour évaluer l'impact des programmes de formation actuels et futurs portant sur cette pratique de fin de vie. Dans cet article, nous présentons brièvement le programme de formation et les étapes futures du développement et de la validation de l'échelle

A revision of the parasitoid wasp genus Alphomelon Mason with the description of 30 new species (Hymenoptera, Braconidae)
The parasitoid wasp genus Alphomelon Mason, 1981 is revised, based on a combination of basic morphology (dichotomous key and brief diagnostic descriptions), DNA barcoding, biology (host data and wasp cocoons), and distribution data. A total of 49 species is considered; the genus is almost entirely Neotropical (48 species recorded from that region), but three species reach the Nearctic, with one of them extending as far north as 45° N in Canada. Alphomelon parasitizes exclusively Hesperiinae caterpillars (Lepidoptera: Hesperiidae), mostly feeding on monocots in the families Arecaceae, Bromeliaceae, Cannaceae, Commelinaceae, Heliconiaceae, and Poaceae. Most wasp species parasitize either on one or very few (2–4) host species, usually within one or two hesperiine genera; but some species can parasitize several hosts from up to nine different hesperiine genera. Among species with available data for their cocoons, roughly half weave solitary cocoons (16) and half are gregarious (17); cocoons tend to be surrounded by a rather distinctive, coarse silk (especially in solitary species, but also distinguishable in some gregarious species). Neither morphology nor DNA barcoding alone was sufficient on its own to delimit all species properly; by integrating all available evidence (even if incomplete, as available data for every species is different) a foundation is provided for future studies incorporating more specimens, especially from South America. The following 30 new species are described: cruzi, itatiaiensis, and palomae, authored by Shimbori & Fernandez-Triana; and adrianguadamuzi, amazonas, andydeansi, calixtomoragai, carolinacanoae, christerhanssoni, diniamartinezae, duvalierbricenoi, eldaarayae, eliethcantillanoae, gloriasihezarae, guillermopereirai, hazelcambroneroae, josecortesi, keineraragoni, luciarosae, manuelriosi, mikesharkeyi, osvaldoespinozai, paramelanoscelis, paranigriceps, petronariosae, ricardocaleroi, rigoi, rostermoragai, sergioriosi, and yanayacu, authored by Fernandez-Triana & Shimbori
A Poorly Known High-Latitude Parasitoid Wasp Community: Unexpected Diversity and Dramatic Changes through Time
Climate change will have profound and unanticipated effects on species distributions. The pace and nature of this change is largely unstudied, especially for the most diverse elements of terrestrial communities – the arthropods – here we have only limited knowledge concerning the taxonomy and the ecology of these groups. Because Arctic ecosystems have already experienced significant increases in temperature over the past half century, shifts in community structure may already be in progress. Here we utilise collections of a particularly hyperdiverse insect group – parasitoid wasps (Hymenoptera; Braconidae; Microgastrinae) – at Churchill, Manitoba, Canada in the early and mid-twentieth century to compare the composition of the contemporary community to that present 50–70 years ago. Morphological and DNA barcoding results revealed the presence of 79 species of microgastrine wasps in collections from Churchill, but we estimate that 20% of the local fauna awaits detection. Species composition and diversity between the two time periods differ significantly; species that were most common in historic collections were not found in contemporary collections and vice versa. Using barcodes we compared these collections to others from across North America; contemporary Churchill species are most affiliated with more south-western collections, while historic collections were more affiliated with eastern collections. The past five decades has clearly seen a dramatic change of species composition within the area studied coincident with rising temperature
Extracellular NAD and ATP: Partners in immune cell modulation
Extracellular NAD and ATP exert multiple, partially overlapping effects on immune cells. Catabolism of both nucleotides by extracellular enzymes keeps extracellular concentrations low under steady-state conditions and generates metabolites that are themselves signal transducers. ATP and its metabolites signal through purinergic P2 and P1 receptors, whereas extracellular NAD exerts its effects by serving as a substrate for ADP-ribosyltransferases (ARTs) and NAD glycohydrolases/ADPR cyclases like CD38 and CD157. Both nucleotides activate the P2X7 purinoceptor, although by different mechanisms and with different characteristics. While ATP activates P2X7 directly as a soluble ligand, activation via NAD occurs by ART-dependent ADP-ribosylation of cell surface proteins, providing an immobilised ligand. P2X7 activation by either route leads to phosphatidylserine exposure, shedding of CD62L, and ultimately to cell death. Activation by ATP requires high micromolar concentrations of nucleotide and is readily reversible, whereas NAD-dependent stimulation begins at low micromolar concentrations and is more stable. Under conditions of cell stress or inflammation, ATP and NAD are released into the extracellular space from intracellular stores by lytic and non-lytic mechanisms, and may serve as ‘danger signals–to alert the immune response to tissue damage. Since ART expression is limited to naïve/resting T cells, P2X7-mediated NAD-induced cell death (NICD) specifically targets this cell population. In inflamed tissue, NICD may inhibit bystander activation of unprimed T cells, reducing the risk of autoimmunity. In draining lymph nodes, NICD may eliminate regulatory T cells or provide space for the preferential expansion of primed cells, and thus help to augment an immune response
Vaccination et grossesse : analyse des lieux de concordance et de conflit de valeurs éthiques entre la philosophie sage-femme et l'approche de la santé publique au Québec
Bien que certains puissent le croire, les conceptions de la santé, de la maladie et sa prévention ne sont aucunement universelles. Elles sont fortement marquées par le contexte culturel dans lequel elles sont construites. L’anthropologie de la santé devient alors une approche très pertinente afin d’analyser les différentes conceptions que peuvent prendre la santé, la maladie et sa prévention dans une culture donnée. En santé publique, l’une des interventions les plus importantes est certainement la vaccination. Souvent critiquée, parfois glorifiée, elle peut incarner une source de conflits éthiques importants, surtout lorsqu’elle s’applique à la femme enceinte. Depuis 2007, des vaccins peuvent être administrés aux femmes enceintes et peuvent être recommandés, non seulement par des médecins réalisant des suivis de grossesse, mais également par des sages femmes. Ayant leur propre philosophie marquant les soins qu’ils octroient, les professionnels de la santé réalisant des suivis de grossesse semblent divisés quant à l’importance de la vaccination chez la femme enceinte. Dans ce contexte, le but de la présente recherche est d’analyser les lieux de concordance et de conflit entre les valeurs éthiques avancées par la santé publique et celles sous-jacentes à la pratique sage-femme, en matière de vaccination chez la femme enceinte au Québec. En explorant chacune des approches, cette recherche permet d’en connaître davantage sur le suivi sage-femme en recueillant des témoignages de femmes enceintes bénéficiant de leurs soins, afin de connaître leur expérience personnelle et la façon dont elles vivent ce type de suivi. Les données présentées dans cette recherche reposent sur des entretiens réalisés avec des sages-femmes et des femmes ayant un suivi sage-femme, mais également sur une analyse du discours de la santé publique concernant la vaccination des femmes enceintes auQuébec.Although some people may believe so, conceptions of health, illness, and prevention are by no means universal. These conceptions are influenced by the social and cultural context in which they are built. The approaches of medical anthropology are very useful for the analysis of these different conceptions in a given culture. In public health, vaccination is one of the most important intervention. Often criticized,sometimes glorified, this intervention can become a source of important ethical conflicts,especially when it applies to pregnant woman. Since 2007, vaccines can be given to pregnant women and can be recommended, not only by physicians who are involved in maternity care, but also by midwives. With different underlying philosophy of care, health professionals who are involved in maternity care appear to be divided over the importance of vaccination for pregnant women. In this context, the purpose of this research is to analyze the concordance and conflict between ethical values promoted in public health and those underlying the midwifery practice, with regard to vaccination of pregnant women in Quebec. By exploring each of the approaches, this research explores the midwifery approach by collecting testimonials from pregnant women under the care of midwives, to know their personal experience and how they live this type of care. The data presented in this research comes from interviews with midwives and women under their care and an analysis of the Quebec public health discourses on vaccination in pregnancy
Keylimepie peckorum gen. n. and sp. n., (Hymenoptera, Braconidae) from southern Florida, U.S., the first known brachypterous member of the subfamily Microgastrinae
Keylimepie peckorum Fernandez-Triana, gen. n. and sp. n., are described from southern Florida, U.S. Females have the shortest wings (0.6–0.7 × body length) of any known microgastrine wasp. The genus can also be recognized on features of the head, propodeum and first three metasomal tergites. All specimens were collected in hammock forests of the Florida Keys and Everglades National Park, but their host caterpillar is unknown. Because its morphology is unique and it is the first new microgastrine genus discovered in North America since 1985, the potential for future conservation of the species is discussed
Seventeen new genera of microgastrine parasitoid wasps (Hymenoptera, Braconidae) from tropical areas of the world
As part of comprehensive studies on the world fauna of microgastrine parasitoid wasps (Hymenoptera: Braconidae) 17 new genera and 29 new species are described from the Afrotropical, Australasian, Neotropical and Oriental regions. The number of extant genera of Microgastrinae is increased by 21% and currently stands at 81. It is anticipated that more genera will be described in the near future, when phylogenetic studies of the group are advanced. The new taxa showcase unusual morphological traits such as atypical head and mouth part modifications, presence of partial occipital and epicnemial carinae, propodeum carination patterns, hind wing venation, trochantellus shape, tarsal claws, sculpture and shape of the first two metasomal tergites, and ovipositor teeth; in some cases, they also represent some of the largest species known in the subfamily. For every new genus putative autapomorphies, morphological diagnostic features, and DNA barcodes (whenever available) are presented, as well as brief discussions of some informal groupings of genera in the subfamily. However, no attempt is made to reassess the phylogeny of the entire Microgastrinae, as that will require more comprehensive analyses beyond the scope of the present work. The following 17 gen. n., authored by Fernandez-Triana, are described: Agupta, Austinicotesia, Billmasonius, Carlmuesebeckius, Gilbertnixonius, Janhalacaste, Jenopappius, Jimwhitfieldius, Kotenkosius, Markshawius, Ohenri, Qrocodiledundee, Silvaspinosus, Tobleronius, Ungunicus, Ypsilonigaster and Zachterbergius. The following 29 sp. n., authored by Fernandez-Triana and Boudreault, are described: Agupta danyi, Agupta jeanphilippei, Agupta raymondi, Agupta solangeae, Austinicotesia indonesiensis, Austinicotesia papuanus, Billmasonius cienci, Carlmuesebeckius smithsonian, Gilbertnixonius biem, Janhalacaste danieli, Janhalacaste guanacastensis, Janhalacaste winnieae, Jenopappius magyarmuzeum, Jimwhitfieldius jamesi, Jimwhitfieldius sydneyae, Kotenkosius tricarinatus, Markshawius erucidoctus, Markshawius francescae, Markshawius thailandensis, Ohenri gouletorum, Qrocodiledundee outbackense, Silvaspinosus vespa, Tobleronius orientalis, Ungunicus vietnamensis, Ypsilonigaster naturalis, Ypsilonigaster sharkeyi, Ypsilonigaster tiger, Ypsilonigaster zuparkoi, and Zachterbergius tenuitergum. The following four comb. n. are proposed: Jenopappius niger (de Saeger, 1944), Jenopappius aethiopica (de Saeger, 1944), Ypsilonigaster bumbana (de Saeger, 1942), and Ypsilonigaster pteroloba (de Saeger, 1944)
