Published: Nov. 7, 2022

Abstract Climate warming is considered to be among the most serious of anthropogenic stresses environment, because it not only has direct effects on biodiversity, but also exacerbates harmful other human‐mediated threats. The associated consequences are potentially severe, particularly in terms threats species preservation, as well preservation an array ecosystem services provided by biodiversity. Among affected groups animals insects—central components many ecosystems—for which climate change pervasive from individuals communities. In this contribution scientists' warning series, we summarize effect gradual global surface temperature increase insects, physiology, behavior, phenology, distribution, and interactions, increased frequency duration extreme events such hot cold spells, fires, droughts, floods these parameters. We warn that, if no action taken better understand reduce will drastically our ability build a sustainable future based healthy, functional ecosystems. discuss perspectives relevant ways conserve insects face change, offer several key recommendations management approaches that can adopted, policies should pursued, involvement general public protection effort.

The worldwide rapid declines in insect and plant abundance diversity that have occurred the past decades gained public attention demand for political actions to counteract these are growing. Rapid large-scale biomonitoring can aid observing changes provide information decisions land management species protection. Malaise traps long been used sampling when insects captured traps, they carry traces of plants visited on body surface or as digested food material gut contents. Metabarcoding offers a promising method identifying traces, providing insight into with which directly interacting at given time. To test efficacy DNA metabarcoding sample types, 79 samples from 21 sites across Germany were analysed ITS2 barcode. This study, our knowledge, is first examination trap samples. Here, we report feasibility sequencing analysis resulting taxa, usage cultivated by near nature conservancy areas detection rare neophyte species. Due frequency contamination false positive reads, isolation PCR negative controls should be every reaction. has advantages efficiency resolution over microscopic identification pollen only possible other could broad utility future studies plant-insect interactions.

Beyond Human Nutrition of Edible Insects: Health Benefits and Safety Aspects

Insects, Journal Year: 2022, Volume and Issue: 13(11), P. 1007 - 1007

Nowadays, edible insects are considered an outstanding source of nutrients, primarily because they contain high-quality protein, amino acids, and vitamins. Insects a promising alternative protein towards alleviating future global food shortage problems due to their production as being more sustainable by using less agricultural land water, well releasing smaller amount greenhouse gas emissions. However, other important aspects consider about the consumption include health benefits some safety aspects, which has been relatively overlooked. In this sense, bioactive compounds that can provide diverse bioactivities, such antioxidant, antihypertensive, anti-inflammatory, antimicrobial, immunomodulatory with positive impact on human health. On hand, nutrient-rich perfect growth medium for microorganisms, possess anti-nutritive factors.

Exposure of insects to current use pesticide residues in soil and vegetation along spatial and temporal distribution in agricultural sites

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 21, 2025

Abstract Current use pesticides (CUPs) are recognised as the largest deliberate input of bioactive substances into terrestrial ecosystems and one main factors responsible for current decline in insects agricultural areas. To quantify seasonal insect exposure landscape at a regional scale (Rhineland-Palatine Germany), we analysed presence multiple (93) active ingredients CUPs across three different cultivation types (with each fields: arable, vegetable, viticulture) neighbouring meadows. We collected monthly soil vegetation samples over year. A total 71 CUP residues mixtures was detected, with up to 28 25 single samples. The concentrations numbers fluctuated sampling period, peaking summer months but remaining almost constant topsoil. calculated in-field additive risks earthworms, collembola, soil-living wild bees using measured CUPs. Our results call need assess mixture low concentrations, chronically present Since this risk is not addressed regulation, emphasise urgent implement global pesticide reduction targets.

Pesticide drift onto non-agricultural land is a common problem in intensively farmed regions, and national action plans have been established across Europe to prevent it. Here, we analyzed official data on pesticide residues grass samples collected over six years determine whether implemented measures reduce were effective.

Different roles of concurring climate and regional land-use changes in past 40 years’ insect trends

Climate and land-use changes are main drivers of insect declines, but their combined effects have not yet been quantified over large spatiotemporal scales. We analysed in the distribution (mean occupancy squares) 390 species (butterflies, grasshoppers, dragonflies), using 1.45 million records from across bioclimatic gradients Switzerland between 1980 2020. found no overall decline, strong increases decreases distributions different species. For that showed strongest (25% quantile), average proportion occupied squares increased 40 years by 0.128 (95% credible interval: 0.123-0.132), which equals an increase mean 71.3% CI: 67.4-75.1%) relative to 40-year occupancy. declines decreased 0.0660 0.0613-0.0709), equalling decrease 58.3% 52.2-64.4%).
