Silk, a remarkable protein-based fiber spun by various arthropod lineages, has been prized for millennia, with the cocoon silk of domesticated silkworms and spiders being most utilized extensively studied. There is limited information on how can be used to investigate biology, development, health in other silk-producing species, particularly solitary bees such as Osmia lignaria Say (Hymenoptera: Megachilidae). , an increasingly managed pollinator, produces cocoons during fifth instar larval stage. We have developed minimally invasive protocol isolate mechanically test O. fibers using 3-D printed well plate system rearing two specific isolation techniques.

The Earth’s entomofauna seems in an ongoing state of collapse. Insect decline could pose a global risk to key insect-mediated ecosystem functions and services such as soil freshwater (nutrient cycling, formation, decomposition, water purification), biological pest control, pollination food web support that all are critical functioning, human health survival. At present the attention for insect is low domains, ranging from scientific research policy-making nature conservation. Scientists made urgent calls prioritise An international treaty pollinator stewardship restoration urgently needed counteract current crisis. A review conservation policies found despite public outcry develop polices addresses declines, governments have not delivered legislation, nor they met basic monitoring needs recommended by experts.

Background: Since the Industrial Revolution, humanity has amassed great wealth and achieved unprecedented material prosperity. These advances have come, however, at cost to planet. They are guided by an economic model that focuses almost exclusively on short-term gain, while ignoring natural capital human capital. relied combustion of vast quantities fossil fuels, massive consumption earth's resources, production environmental release enormous chemicals, pesticides, fertilizers, plastics. caused climate change, pollution, biodiversity loss, "Triple Planetary Crisis". responsible for more than 9 million premature deaths per year widespread disease – impacts fall disproportionately upon poor vulnerable. Goals: To map health loss. outline a framework assessing benefits interventions against these threats. Findings: Actions taken national governments international agencies mitigate loss can improve health, prevent disease, save lives, enhance well-being. Yet assessment is largely absent from evaluations remediation programs. This represents lost opportunity quantify full educate policy makers public. Recommendations: We recommend implementing develop metrics strategies quantifying interventions. they deploy tools in parallel with assessments ecologic benefits.

Wild and managed bees provide pollination services to crops wild plants, as well a variety of other beneficial humans. Honey are the most economically valuable pollinator worldwide. It has been calculated that 9.5% total economic value agricultural production comes from insect pollination, thus amounting just under USD 200 billion globally. More than 100 important depend on by honey bees. The latter pollinate not only wide number commercial but also many some which threatened extinction constitute genetic resource.
