“…In contrast, parental exposure to ivermectin did not affect offspring body size of either sex. This result is similar to that found for the dung beetle E. intermedius (Baena-Díaz et al, 2018). Given that the offspring dung was not contaminated by ivermectin, it is therefore likely that the surviving offspring ultimately had similar metabolic rates as those produced by uncontaminated parents.…”

“…This finding highlights a transgenerational carry-over effect of parental exposure to toxic substances. Similar parent-to-offspring carry-over effects of toxic substances on emergence success were obtained in beetles (Baena-Díaz et al, 2018;Müller et al, 2019). By analyzing egg hatching success, we could disentangle mortality occurring during the egg vs. larval stage.…”

“…Given that the offspring dung was not contaminated by ivermectin, it is therefore likely that the surviving offspring ultimately had similar metabolic rates as those produced by uncontaminated parents. More information on the competitive ability and lifetime reproductive output of these flies is needed for stronger conclusions about these transgenerational effects (Jann et al, 2000), and more studies are required to unravel whether parental investment or epigenetic processes play a role in maintaining offspring body size and fitness in ivermectin-contaminated environments (Baena-Díaz et al, 2018). Van Koppenhagen et al (2020) demonstrated that adult yellow dung flies of both sexes feeding on ivermectin-contaminated sugar also experienced negative effects on several life-history, behavioral and reproductive traits, most notably a reduction in male fertility and, specifically, testis size (even when controlling for female contamination).…”

Fitness consequences of the combined effects of veterinary and agricultural pesticides on a non-target insect

Pesticides and veterinary products that are globally used in farming against pests and parasites are known to impact non-target beneficial organisms. While most studies have tested the lethal and sub-lethal effects of single chemicals, species are exposed to multiple contaminants that might interact and exacerbate the toxic responses of life-history fitness components. Here we experimentally tested an ecotoxicological scenario that is likely to be widespread in nature, with non-target dung communities being exposed both to cattle parasiticides during the larval stage and to agricultural insecticides during their adult life. We assessed the independent and combined consumptive effects of varying ivermectin and spinosad concentration on juvenile life-history and adult reproductive traits of the widespread yellow dung fly (Scathophaga stercoraria; Diptera: Scathophagidae). Larval exposure to ivermectin prolonged development time and reduced egg-to-adult survival, body size, and the magnitude of the male-biased sexual size dimorphism. The consumption by the predatory adult flies of spinosad-contaminated prey showed an additional, independent (from ivermectin) negative effect on female clutch size, and subsequent egg hatching success, but not on the body size and sexual size dimorphism of their surviving offspring. However, there were interactive synergistic effects of both contaminants on offspring emergence and body size. Our results document adverse effects of the combination of different chemicals on fitness components of a dung insect, highlighting transgenerational effects of adult exposure to contaminants for their offspring. These findings suggest that ecotoxicological tests should consider the combination of different contaminants for more accurate eco-assessments.

“…Also, in the present study, weights of individuals at each of the developmental stages did not vary statistically significantly in generations of the FipA, FipL, ChlA, and ChlL strains except larval weight in the tenth generation of the ChlA strain (Table 4). Baena-Díaz et al (2018) showed that parental (mainly paternal) exposure of the dung beetle Euoniticellus intermedius Reiche, 1849 (Coleoptera, Scarabaeidae) to ivermectin had trans-generational effects on the morphological features of male offspring but did not affect offspring number, sex ratio or body size.…”

Insect populations exist under acute and chronic exposures to lethal and sublethal insecticide concentrations. Among the sublethal effects of insecticides on insects are reductions in life span, development rates, population growth, fertility, fecundity, changes in sex ratio, deformities, changes in behaviour, feeding, searching, and oviposition. These effects may differ depending on the modes of action of insecticides, their doses, and developmental stage of application. This study evaluated the life-history parameters in Musca domestica Linnaeus, 1758 (Diptera:Muscidae) strains that were exposed to two insecticides (fipronil and chlorfenapyr) with different modes of action at sublethal concentrations in each generation up to tenth. Two approaches to each insecticide’s exposure were used in this study, particularly in one approach, only adults M. domestica were exposed to fipronil or chlorfenapyr and in another approach, only larvae were exposed to each insecticide. The susceptibility of adult flies to these insecticides was assessed by resistance ratio based on results of non-choice feeding bioassays. Fipronil exposure at the sublethal concentration in each generation did not affect the susceptibility of adult M. domestica (in the tenth generation) to fipronil. The resistance ratio values revealed tolerance to chlorfenapyr in adults of M. domestica strains that were exposed to this insecticide, independent of the approach used to insecticide exposure. Most of the life-history parameters (such as durations of separate developmental stages, the emergence duration, the adult emergence ratio, the female ratio, and the number of eggs per female per day) of the second, fourth, sixth, eighth, and tenth generations of the insecticide-exposed strains were similar to those of the control strain. At the same time, the sublethal effects of both insecticides fipronil and chlorfenapyr prolonged the larval duration (1.63–2.22 times) and the number of days from egg to adult (1.18–1.39 times) compared to the control strain. Further studies are needed to investigate a possible genetic variability in M. domestica in response to exposure of parental generation to sublethal doses of fipronil and chlorfenapyr.

“…Endectocides treated animals excrete residue of parasiticides primarily in the feces, thus making it poisonous for dung dwelling or eating arthropod fauna, reducing insect abundance associated with the dung decomposition resulting in severe ecological and economic costs (Baena-Díaz et al, 2018). Owing to low mammalian toxicity the endectocides and veterinary parasiticides, are globally used against arthropods and nematode parasites (Floate, 2006).…”

We explored the effect of endectocides (deltamethrin and trichlorophenol) and antibiotics (enrofloxacin and oxytetracycline) on dung beetle species, 0nthophagus gazella and 0nitis excavatus under laboratory conditions. 0. gazella and 0. excavatus were collected from pastures and crop lands of Jhelum, Punjab, Pakistan. The selected endectocides and antibiotics were applied on dung pats placed over soil @ 0.25, 0.50, 0.75 and 1 ppm and kept in glass containers of 2' x 2' x 1.5' size. The laboratory bioassay was carried out at 28 ± 2 °C temperature and 65 ± 5 % RH with 12:12 of light to darkness ratio. Our results demonstrated that deltamethrin, trichlorophenol and oxytetracycline were toxic to both species, 0. gazella and 0. excavatus after two weeks of the exposure. Comparatively higher dung beetle mortality was recorded in both deltamethrin and trichlorophenol when applied @ 1 ppm as compared to 0.25, 0.50 and 0.75 ppm concentrations in 0. gazella and 0. excavatus showed significantly higher mortality against oxytetracycline (53.3 % and 93.3 %, respectively), trichlorophenol (80 % and 94 %, respectively) and deltamethrin (88% and 76 %, respectively) at 1 ppm concentrations, whereas no mortality was recorded in all concentrations of enrofloxacin. 0. gazella and 0. excavatus responded negatively to the presence of different concentrations of veterinary parasiticides. In addition to the hazardous effect of 0. gazella and 0. excavatus, the study reports that these dung beetle species can be exploited as bio-indicators for environmental assessment in ecosystem studies.
