Detritivorous arthropods are essential because they participate in recycling organic matter, decomposing pesticides, improving soil properties, conserving water, and reducing problems with plant diseases. Practices such as no-till and straw on soils can affect soil properties and populations of detritivorous arthropods. Brazil is the largest producer and consumer of common beans (Phaseolus vulgaris). Thus, this work aimed to determine the impact of no-till and straw planting on detritivorous arthropods on the "surface over ground" in common bean crops. In this way, common beans were cultivated in tillage and no-till with and without straw on the soil. During cultivation, the density of detritivorous arthropods on the soil was monitored using a pitfall trap. Sixteen morphospecies of detritivorous arthropods were observed on the surface of the ground. No-tillage and straw did not affect the number of detritivorous arthropod species. The most abundant morphospecies was the Collembola Entomobryidae and Hypogastrura sp. and the Coleoptera Scarabaeidae and Colopterus spp. No-till and straw positively affected the abundance of detritivorous arthropods. Therefore, no-tillage and straw in bean crops provide conditions for increasing detritivorous arthropod populations, improving soil properties.

Brazil is an important global agricultural producer and to increase production the country has extensively used glyphosate-based herbicides (GBH), surpassing consumption and sales records. Consequently, concerns have arisen regarding the potential impact of GBH on ecosystems and non-target organisms. Thus, the effects of GBH exposure were evaluated throughout the cricket Gryllus (Gryllus) assimilis ontogeny, with five developmental stages. Each period contained 3 control and 3 treated boxes, with 15 crickets each, resulting in 90 insects at a time. The control groups received water, while the treated ones were continuously exposed to GBH (0.864 mg.GBH.L-1), with the solutions changed every 48 hours. After each exposure time the crickets’ group were euthanized to assess the activity of antioxidant enzymes (GST, GR, GPx, and CAT), cholinergic enzymes (ChE), and lipid peroxidation (LPO). The results revealed changes in the systems throughout different developmental phases. Specifically, CAT activity exhibited a significant increase during the nymphal phase, associated with the dismutation of hydrogen peroxide. The GST increased GBH, indicating its role in cellular detoxification, particularly during adulthood. In the senescence stage there was a considerable rise in ChE enzymes, suggesting their involvement in both, choline esters breakdown and potential pesticide detoxification. The action of these enzymes to effectively control lipid peroxidation shows the adaptability of this species to environmental contamination. These findings underscore the long-term effects of agrochemical pollution and emphasize the importance of sustainable practices, effective regulations, and alternative weed control methods.

Glyphosate is the most widely used active ingredient (AI) in glyphosate-based herbicides (GBHs) worldwide and is also known to affect a variety of soil organisms. However, we know little about how the effects of glyphosate AIs differ from those of GBHs that also contain so-called inert co-formulants. We conducted a greenhouse experiment using the model cover crop white mustard (Sinapis alba) to investigate the effects of three GBHs (Roundup PowerFlex, Roundup LB Plus, and Touchdown Quattro) and their respective glyphosate AIs (glyphosate potassium, isopropylamine, and diammonium salt) on epedaphic springtails (Sminthurinus niger; Collembola) activity in soils with low (3.0%) or high (4.1%) organic matter content (SOM). Springtail activity was assessed using pitfall traps. Most GBHs and AIs reduced springtail activity compared to mechanical removal of mustard in the short-term and even up to 5 months after application. GBHs and AIs differed considerably in their effects on springtail activity, and effects were modified by SOM content. Our results highlight the need to (i) distinguish between the effects of glyphosate AIs and commercial GBH formulations, (ii) disclose all ingredients of GBHs, as co-formulants also affect non-target organisms, and (iii) include soil properties in ecotoxicological risk assessments for soil organisms to better characterize the situation in the field.
