Human babesiosis is a disease transmitted by the bite of an infected tick or via blood transfusions involving contaminated blood products; in humans, it can lead to severe complications and even death, depending on the clinical history, age and health status of the affected patient. Babesiosis is caused by members of the Babesia spp., protozoan parasites whose life cycle includes sexual reproduction in the arthropod vector and asexual reproduction in the mainly mammalian host. Cases of human babesiosis have been rare, but there are increasing reports of human babesiosis associated with climatic changes affecting the geographical distribution of the parasite and tick vector, enhanced vector–human interactions and improved awareness of the disease in humans. Diagnostics and treatment options for humans are based around discoveries in veterinary research, such as point-of-care testing in cases of bovine babesiosis, and include direct diagnosis by blood smears, polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) technologies, and indirect diagnosis by ELISA, immunofluorescence tests (IFAT) and fluorescent in situ hybridisation. Treatment involves a combination of drugs such as azithromycin and atovaquone, or clindamycin and quinine, but more effective options are being investigated, including, but not limited to, trans-chalcones and tafenoquine. Improved surveillance, awareness and diagnosis, as well as advanced technologies to interrupt vector–host interactions, are crucial in managing the increased threat posed by this once-neglected disease in humans.

The invasive plant species Japanese hop (Humulus japonicus Sieb. & Zucc.) and reed canarygrass (Phalaris arundinacea L.) are increasing in cover in Upper Mississippi River floodplains where they negatively impact native vegetation. This study evaluated novel reforestation methods to rapidly close canopy openings colonized by invasives and reduce their cover at four study sites ranging from southern Wisconsin to southwestern Illinois. Each site contained three replicates of four 20x20m plots comprising four tree planting treatments. These included two using large diameter willow (Salix L.) cuttings planted at different densities, one using container stock of American sycamore (Platanus occidentalis L.) and eastern cottonwood (Populus deltoides W. Bartram ex Marshall), and a control plot with no planted trees. Half of each planting treatment also received maintenance treatments for invasives control. Results indicated that planting and maintenance had significant effects on tree survival, invasives cover, and plant community diversity. Specifically, trees that received maintenance had higher survival than those that did not, and Salix cuttings had higher survival than container stock. Annual tree height growth was greatest in Salix cuttings planted at the highest density. Invasive species cover declined significantly maintenance treatments and Salix plantings. Change in plant community diversity was greater in maintenance treatments and in Salix plantings, but was still extremely low at the northernmost site. Vegetation patterns were strongly influenced by invasives and reinforced the general inverse relationship between plant community diversity and invasives cover. Overall, results indicated that tree plantings using large Salix cuttings can be an effective method to quickly reforest areas along the Upper Mississippi River that have been colonized by invasive plant species, and that incorporating tree planting maintenance activities in early years can lead to better survival.

Unhealthy diets are a leading cause of preventable ill health. Healthy diets tend to be more expensive than less healthy diets and as such are more likely to be consumed by individuals with a higher income. This review paper discusses the development of the Eatwell Guide, evaluates the affordability of a diet consistent with the Eatwell Guide (‘the Eatwell Guide diet’) and explores how food pricing can be leveraged to encourage and support healthier dietary choices. The Eatwell Guide is the UK’s food-based dietary guidelines. It provides healthy eating advice that is intended to facilitate policy cohesion but is also used as a public-facing health promotion tool. The cost of food has increased and recent estimates suggest that the Eatwell Guide diet is now more expensive than the current average diet. There is strong evidence that subsidies would be effective at increasing the uptake of healthy diets. Monitoring the cost of a healthy diet is important for policy development; however, we should exercise caution when considering how to incorporate costs into food-based dietary guidelines and be mindful of the limitations of the data that could support this.

True bugs (Hemiptera: Acanthosomatidae, Coreidae, and Pentatomidae) include harmful crop pests affecting global agriculture, with different species displaying distinct optimal conditions for development and using different habitats. Over a 2-year period, this research investigates how habitat variation and altitude can influence the species composition of true bugs and their egg parasitoids in South Tyrol (North Italy), unveiling different trends in their population and diversity across habitats: apple orchards, urban areas, and forests. A total of 25 true bug species were sampled. Urban environments hosted the highest bug abundance, predominantly driven by the invasive Halyomorpha halys, while forests showed a higher prevalence of native species such as Pentatoma rufipes and Palomena prasina. Altitude significantly influenced species composition, with H. halys and P. rufipes abundance negatively and positively correlated with altitude, respectively. A total of 12 parasitoid species (Hymenoptera: Eupelmidae, and Scelionidae) emerged from the field-collected bug eggs, including the exotic Trissolcus japonicus, predominantly associated with H. halys in urban areas. Native parasitoids exhibited higher parasitism rates on native bug species, indicating co-evolutionary relationships. The results give an insight into the ecological dynamics of local true bug species and their egg parasitoids, and highlight the value of natural and urban areas for conserving both hemipteran and parasitoid species richness and abundance.

Healthy diets are unaffordable for billions of people worldwide, with food prices rising in high-, middle- and low-income nations in recent times. Despite widespread attention to this issue, recent actions taken to inform policy prioritisation and government responses to high food inflation have not been comprehensively synthesised. Our review summarises (i) innovative efforts to monitor national food and healthy diet price, ii) new policy responses adopted by governments to address food inflation and (iii) future research directions to inform new evidence. Evidence synthesis. Global. None. We describe how timely food and beverage pricing data can provide transparency in the food industry and identify key areas for intervention. However, government policies that improve food affordability are often short-lived and lack sustained commitment. Achieving meaningful impact will require long-term, cross-sectoral actions that are led by governments to support food security, healthy diets and resilient sustainable food systems. This will necessitate a better understanding of how the political economy enables (or hinders) policy implementation, including through coherent problem framing, mitigating conflicts of interest in policymaking, working together as coalitions and developing and utilising evidence on the food security and related impacts of food pricing and affordability policies. Diverse actors must be better equipped with robust data platforms and actionable policy solutions that improve the affordability of healthy and sustainable diets, including by lowering food prices and addressing the broader socio-political determinants of food insecurity.

Two Xiphinema species, one new and one known, were found from Bushehr province, southern Iran, and are herein described based on morphological and molecular data. These include Xiphinema pedrami sp. nov. and X. basiri, both belonging to the ‘Xiphinema non-americanum group’. The new dagger nematode is characterised by a body length of 3.54–5.00 mm, a lip region separated from the rest of body by a depression, odontostyle 128–148 μm long, 60–89 μm long odontophore, guiding ring at 107–138 μm from anterior end, female tail rounded to dorsally more convex with small bulge and four juvenile stages. Males have one pair of cloacal and three to five ventromedian single supplements. The new species belongs to morphospecies Xiphinema non-americanum group 5, characterised by having two equally developed female genital branches with uterine differentiation in the form of pseudo-Z-organ along with the rhomboid-shaped crystalloid bodies, and a short, rounded tail ending in a peg. The polytomous identification codes of the new species are A4, B2, C5a5b, D6, E56, F4(5), G23, H2, I34, J5a5b, K3, L2. Morphologically, the new species comes close to several known species (namely, X. andalusiense, X. artemisiae, X. baetica, X. hyrcaniense, X. ingens, X. macroacanthum and X. pseudocoxi) belonging to morphospecies group 5. The morphological differences of the new species and the aforementioned species are discussed. The second recovered species, Xiphinema basiri, belongs to the same group and has a pseudo-Z-organ in the shape of globular bodies close to pars dilatata uterus and short, conical, distinctly digitate tail. Integrative diagnosis was completed using molecular data obtained from partial sequences of the D2-D3 region of 28S rDNA, ITS1 rDNA, 18S rDNA, and COI mtDNA genes.
