“…E. crypticus gained growing attention in soil ecotoxicological studies due to practical advantages: (1) Is cultured in agar medium, (2) has a high reproductive rate, (3) relatively short generation time and test period, and (4) wider tolerance range to different soil properties (pH, texture, and organic matter content) [24]. Several studies already showed that E. crypticus is a valuable bioindicator of contaminated environments from a large range of anthropogenic sources, including pesticides [15][16][17]26].…”

Worldwide, pesticides have contaminated the environment, affecting non-target species. The aim of this work was to evaluate the effects of fosetyl-Al (FOS) on model organisms. Based on the 3 Rs for animal research and described guidelines, the OECD 236 and 220 were applied with some modifications. The FOS test concentrations were 0.02–0.2–2–20–200 mg/L for Danio rerio and 250–500–750–1000–1250 mg/kg for Enchytraeus crypticus. Besides the standard endpoints, additional endpoints were evaluated (D. rerio: behavior and biochemical responses; E. crypticus: extension of exposure duration (28 d (days) + 28 d) and organisms’ sizes). For D. rerio, after 96 h (h), hatching was inhibited (200 mg/L), proteins’ content increased (2 and 20 mg/L), lipids’ content decreased (2 mg/L), glutathione S-transferase activity increased (2 mg/L), and, after 120 h, larvae distance swam increased (20 mg/L). For E. crypticus, after 28 d, almost all the tested concentrations enlarged the organisms’ sizes and, after 56 d, 1250 mg/kg decreased the reproduction. In general, alterations in the organisms’ biochemical responses, behavior, and growth occurred at lower concentrations than the effects observed at the standard endpoints. This ecotoxicological assessment showed that FOS may not be considered safe for the tested species, only at higher concentrations than the predicted environmental concentrations (PECs). This research highlighted the importance of a multi-endpoint approach to assess the (eco)toxic effects of the contaminants.

“…Maccari et al (2020), for example, observed negative effects on springtail reproduction (Folsomia candida), resulting in an effective concentration for 50% of the exposed organisms (EC 50 ) of 7.5 g kg − 1 . Testa et al (2020) reported effects on the reproduction of Enchytraeus crypticus soil worms exposed to 5.0 g kg − 1 poultry litter containing the pyrethroid insecticide cypermethrin. With regard to earthworms, lethal, behavioral, reproductive and cytotoxic effects have recently been reported for Eisenia andrei exposed to FQcontaminated poultry litter (Parente et al 2021).…”

Poultry litter is widely applied as a fertilizer even though it is one of the main antibiotic sources for agricultural soils. Long-term sublethal effects (56 days) on the antioxidant system of Eisenia andrei earthworms following exposure to uoroquinolone-contaminated poultry litter (enro oxacin + cipro oxacin) at 5.0, 10 and 20 g kg -1 were evaluated. The following biomarkers were assessed: superoxide dismutase (SOD), catalase (CAT), glutathione-S-trasferase (GST), reduced glutathione (GSH) and a lipid peroxidation (LPO) proxy. Signi cant CAT and SOD increases and a moderate positive correlation (ρ = 0.67, p < 0.05) between these enzymes was observed. Glutathione-S-trasferase levels increased signi cantly at 10 g kg -1 , while GSH exhibited a dose-dependent response at 5.0 mg kg -1 (4 -106%), 10 mg kg -1 (28 -330 %) and 20 mg kg -1 (45 -472%). LPO levels exhibited a decreasing trend with increasing poultry litter concentrations of 8 -170% (5.0 g kg -1 ), 7 -104% (10 mg kg -1 ) and 3 -6% (20 mg kg -1 ). A Principal Component Analysis (PCA) highlighted increased SOD and CAT activities, possibly due to increases in reactive oxygen species (ROS) concentrations. Biological Health Status assessments based on the Biomarker Response Index indicate major alterations in the rst month of exposure, changing to moderate in the second month. These ndings indicate an antioxidant system attenuation trend. It is possible, however, that successive poultry litter applications may reduce the long-term recovery capacity of the evaluated biomarkers.

“…Despite the results achieved, studies on the reproduction of useful entomophages in the fight against zoophilic insects, the use of microbiological and pyrethroid medicines in the fight against ectoparasites and animal estrosis have been conducted at an insufficient level in animal husbandry [13].…”

Recently, tangible results have been achieved in veterinary medicine in the use of biological methods for combating zoophilic insects and ectoparasites, and the use of microbiological and pyrethroid preparations with a plant base. Zoophilic insects and mites as ecto- and endoparasites parasitize on the body of animals and humans cause infestation, that is, parasitosis (entomoses and acarosis), as a result of which the milk productivity of cattle decreases to 30-40 percent, meat productivity annually decreases by 10-12 kilograms, and also negatively affect the growth and development of young animals and lead to death.
