Abstract	Background: In temperate regions, aphid biological control in greenhouses is mostly achieved by the regular release of biocontrol agents. Due to the rapid growth rate of the aphid population, biocontrol agents must be released frequently in order to be present before pest outbreaks and to act rapidly to prevent exceeding the economic threshold. Banker plants reduce these numerous releases by providing natural enemies with a high-quality environment to develop and reproduce. Optimally, banker plants should be easy to produce, resistant to environmental conditions, provide a large amount of suitable banker prey in order to produce a high number of biocontrol agents, and resist the herbivory pressure of the banker prey. The present study aimed to compare the value of three banker plant candidates of the Poaceae family under laboratory and greenhouse conditions: barley (Hordeum vulgare L.), finger millet (Eleusine coracana (L.) Gaertn), and corn (Zea mays L.). Results: Our results show that the three plants were suitable for different contexts. Finger millet yielded the biggest fresh plant biomass, supported the highest load of banker prey, and resisted aphid feeding longer than the other plant species. Corn was the cheapest to produce, and barley was the fastest to grow. Conclusions: Overall, finger millet could be more fitted for long crop cycles, pests with rapid population growth rates, and voracious or fast-reproducing biocontrol agents. Meanwhile, barley and corn may be better suited for rapid crop cycles, pests with slow population growth rates, and biocontrol agents that are not too voracious or have low reproductive rates. © 2024 The Authors.

Abstract	No matter what rung someone holds on the social ladder, they are likely to experience better health and happiness than those below them in the hierarchy and poorer health and happiness than those above. Social gradients have been found for cardiovascular, respiratory, rheumatoid, and psychiatric disease as well as mortality from all causes. These findings are often mediated by subjective social status, defined as a person's perceptions of their place in the social structure. Social gradients have also been found for happiness, which seems to be affected by sociometric status (i.e. being respected by others) more than by socioeconomic status (e.g. income). I conclude by considering the extent to which social hierarchies scaffold the fulfillment of people's basic psychological needs.

Abstract	Psychologists have studied the ancient concept of wisdom for 3 decades. Nevertheless, apparent discrepancies in theories and empirical findings have left the nomological network of the construct unclear. Using multilevel meta-analyses, we summarized wisdom's correlations with age, intelligence, the Big Five personality traits, narcissism, self-esteem, social desirability, and well-being. We furthermore examined whether these correlations were moderated by the general approach to conceptualizing and measuring wisdom (i.e., phenomenological wisdom as indexed by self-report vs. performative wisdom as indexed by performance ratings), by specific wisdom measures, and by variable-specific factors (e.g., age range, type of intelligence measures, and well-being type). Although phenomenological and performative approaches to conceptualizing and measuring wisdom had some unique correlates, both were correlated with openness, hedonic well-being, and eudaimonic well-being, especially the growth aspect of eudaimonic well-being. Differences between phenomenological and performative wisdom are discussed in terms of the differences between typical and maximal performance, self-ratings and observer ratings, and global and state wisdom. This article will help move the scientific study of wisdom forward by elucidating reliable wisdom correlates and by offering concrete suggestions for future empirical research based on the meta-analytic findings.

Abstract	The foxglove aphid, Aulacorthum solani (Kaltenbach) (Hemiptera: Aphididae), has become a significant pest in horticulture as it can build high populations from 10 to 18 °C, when no commercially available biocontrol agent is efficient. The American hoverfly, Eupeodes americanus (Wiedemann) (Diptera: Syrphidae), has demonstrated good active flight, oviposition, and larval voracity at low temperature. In the present study, the efficiency of a banker plant system using the American hoverfly was evaluated in a cage experiment (enclosed space) and commercial greenhouses (open environment) at production temperatures (heating temperature was 18 °C). The results demonstrate that banker plants with the American hoverfly provided an adequate control of foxglove aphid populations in both environments. In a cage experiment, the predator used the banker plant for nutritional resources and successfully developed and reproduced on them. Green pepper plants infested by foxglove aphids and exposed to hoverflies show a significantly lower abundance of aphids by the end of the trial, compared to the control cages. In commercial greenhouses (real situation), adult hoverflies were able to mate, locate infested plants, and oviposit. Subsequently their offspring provided an efficient control of aphid populations after 6 weeks. This study demonstrates the high potential of a banker plant using hoverflies in greenhouse environments. It also demonstrates the importance of studying new potential biocontrol agents.

Abstract	The alternative model of personality disorders were designed to represent the presence of personality dysfunction (Criterion A) and pathological personality traits (Criterion B). Much of the empirical attention toward this model has been directed toward testing the performance of Criterion B. However, the development of the Levels of Personality Functioning Scale-Self-Report (LPFS-SR) has sparked a growing amount of interest and debate around Criterion A. Specifically, there is significant disagreement in the research examining the validity of the LPFS-SR, with ongoing discrepancies regarding the measure's underlying structure and measurement of Criterion A. The present study aimed to compare four models (one-factor, four-factor, higher order, and bifactor models) in a sample of 416 adults (49.5% women, 63.5% White) to better understand the structure of the LPFS-SR. This study also built on existing efforts to establish convergent and divergent validity of the LPFS-SR by examining how criteria are related to independent measures of both self and interpersonal pathology. The results from the present study supported a bifactor model. Additionally, the four subscales of the LPFS-SR each captured unique variance above and beyond the general factor. Structural equation models predicting identity disturbance and interpersonal traits demonstrated that while the strongest relationships were found between the general factor and the scales, some support was found for the convergent and discriminant validity of the four factors. This work advances our understanding of the LPFS-SR and provides support for the LPFS-SR as a valid marker of personality pathology in clinical and research settings.

Abstract	Objective and background: How do targets shape consensus in impression formation? Targets are known to play an outsized role in the accuracy of first impressions, but their influence on consensus has been difficult to study. With the help of the recently developed extended Social Relations Model, we explore the structure and correlates of individual differences in consensus (i.e., dissensus). Method: Across 3 studies, 187 photographs of targets were rated by 960 perceivers on personality and evaluative traits, as well as being coded for physical cues by trained coders. We explored the within-target consistency of consensus across traits, as well as its relationship to four categories of theoretically relevant correlates: expressiveness, normativity, positivity, and social categories. Results: The tendency to make a consistent impression on others was broadly consistent across traits. High-consensus targets tended to be more expressive, had more normative physical cues, and were viewed more positively. Conclusions: At least in a first impression context, targets may play a unique role in predicting the consensus of personality judgments by providing perceivers with more information to work with, and making a negative impression on others may carry social costs.

Abstract	Aphids (Hemiptera: Aphididae) are a major economic problem in numerous crops, including pepper, melon, and potato. Larvae of the American hoverfly, Eupeodes americanus (Wiedemann) (Diptera: Syrphidae), are common aphidophagous natural enemies in agrosystems in North America. The objective of the present study was to characterize the development cycle of E. americanus in order to evaluate its potential as a biocontrol agent. The development cycle, survival rate, and adult longevity of E. americanus were determined and compared with those of the commercial aphid midge Aphidoletes aphidimyza (Rondani) (Diptera: Cecidomyiidae) under laboratory conditions, using the green peach aphid, Myzus persicae (Sulzer), as prey. The complete preimaginal development time, pupal development time, egg hatching rate, sex ratio, and survival rate were not different between E. americanus and the commercial A. aphidimyza. The larval developmental time was longer in the syrphid species, increasing the predation window. Finally, the adult longevity of the syrphid was drastically longer than that of A. aphidimyza. These results demonstrate a potential for E. americanus as a new aphidophagous biocontrol agent.

Abstract	Objective: Our aim in this study was to determine the safety, glycemia, and quality of life (QoL) associated with in-clinic installation and management of supported open-source artificial pancreas systems (SOSAPS) in type 1 diabetes (T1D). Methods: This investigation is a retrospective cohort study of consecutive SOSAPS users at a Canadian diabetes centre. SOSAPS were offered to all moderately tech-savvy T1D clients on sensor-augmented multiple daily injection or pump, able to pay for hardware, and willing to sign a consent and waiver document. SOSAPS were installed and maintained by clinic staff at no cost to clients. iPhone users were assigned to either Loop (n=108) or iPhone artificial pancreas systems (iAPS; n=114) and Android users to Android-type APS (n=24). Outcomes included severe hypoglycemia and diabetic ketoacidosis (DKA), time in range (TIR) 4.0 to 10.0 mmol/L, time below range (TBR) <4 mmol/L, glucose management indicator (GMI), mean sensor glucose (MSG), change in glycated hemoglobin (A1C), and QoL. Results: Two hundred forty-eight subjects (131 males, 117 females), with a mean age of 36 years and diabetes duration of 21 years, experienced 3 episodes of severe hypoglycemia and no DKA over a follow-up of 17 months. TIR rose by 16%, from 64% to 80% (p<0.0001); TBR fell by 1.0%, from 3.5% to 2.5% (p=0.001); MSG fell from 9.0 to 8.1 mmol/L (p<0.001); GMI fell from 7.3% to 6.7% (p<0.001); and A1C fell from 7.2% to 6.7% (p<0.0001). QoL scores were healthy before and improved after SOSAPS. Conclusions: Clients with T1D using SOSAPS and supported with no-cost care to the client (software, technology, and physician/physician assistant) safely achieved improved TIR, GMI, A1C, and QoL.

Abstract	The foxglove aphid, Aulacorthum solani Kaltenbach (Hemiptera: Aphididae), has become a significant pest in horticulture as it can up build high populations from 10 to 18°C. Currently, chemical control is used as no commercially available biocontrol agent is effective at these temperatures. In this study, two potential biocontrol agents were evaluated: the silverfly, Leucopis glyphinivora Tanasijtshuk (Diptera: Chamaemyiidae), and the American hoverfly, Eupeodes americanus (Wiedemann) (Diptera: Syrphidae). Active flight, oviposition, and larval voracity were tested at 12, 15, and 18°C. The proportion of individuals demonstrating flight decreased at 12°C for the hoverfly and decreased at 15 and 12°C for the silverfly. Delay before active flight was greater for both species at 12°C. More hoverflies laid eggs after 7 d at all temperatures (12, 15, and 18°C) compared with silverflies. Hoverflies laid a higher number of eggs than silverflies at all temperatures. When given an additional 7 d at 12°C, oviposition increased for both species. Daily aphid consumption decreased as temperature decreased for both species, but average total aphid consumption did not decrease regardless of the temperature. This means that larval voracity for both the silvery and the American hoverfly was similar at all temperatures (12, 15, and 18°C) when considering aphid development. Hoverfly larvae consumed two times more aphids than silverfly larvae at all temperatures. This study demonstrates a clear superiority of the hoverfly over the silverfly at low temperatures and identifies it as a potential biocontrol agent of the foxglove aphid.
