“…Earwigs sampled in conventional orchards had shorter femurs suggesting that a high historic level of insecticide exposure is needed to influence body shape of these organisms. These findings are consistent with a decrease in body size and elytron length seen for the carabidae, Calathus fuscipes, sampled in potato fields treated with the larvicide lambda-cyhalothrin (Giglio et al, 2017) and with previous analyses on earwigs (Suchail et al, 2018). However, other studies failed to highlight changes in morphological size under insecticide exposure, as for C. pipiens mosquitoes (Taskin et al, 2016) as an example.…”

Widespread use of pesticides to control crop pests is still the dominant system in apple orchards. Therefore, to avoid adverse side effects, there is a growing interest in promoting alternative methods such as natural enemies. The European earwig Forficula auricularia L. (Dermaptera: Forficuidae) is an effective predator in apple orchards. Pesticide pressure has been shown to divert energy resources which could have a negative impact on life history traits. In this study we assessed (i) whether variations in pesticide exposure could differentially impact energy reserves, body weight and morphometric parameters of F. auricularia, and (ii) whether these effects last or not in the next generation reared under optimal conditions. Individuals from the first generation were collected in late October from organic, IPM and conventional orchards. The next generation was obtained under a rearing program, in the absence of pesticide exposure. Earwigs collected from conventional orchards exhibited lower values for all morphometric parameters compared to those collected in organic orchards. However, a relaxed period without pesticide exposure (in autumn) appears to have allowed the females to recover their energy reserves to ensure reproduction and maternal care. Glycogen contents are the reserves that were more easily restored. However, due to the rearing conditions (food ad libitum), all the earwigs from the second generation exhibited higher body weights and energy reserves than their parents. They finally reached the same level in these parameters regardless of the protection system from which their parents were collected. Sex-specific responses appeared to depend on earwig life cycle.

“…In Pterostichus melasitalicus, a carabidae, morphometric analyses also showed that dimethoate application caused a reduction in body or elytra lengths in females (Giglio et al 2011). Giglio et al (2017) showed in another carabidae, Calathus fuscupes, that morphological parameters e.g. body and pronotum width decreased after an exposure to the larvicide lambda-cyhalothrin.…”

Apple orchards are heavily treated crops and some sprayed insecticides are recognized to have toxic effects on non-target arthropods. Earwigs are important natural enemies in pip-fruit orchards and contribute to the biological control of aphids. In addition, due to their ease of capture and identification, they are an interesting potential bioindicator of the possible detrimental effects of different orchard management strategies. In this study, we measured the energy reserves and some morphological traits of Forficula auricularia L. sampled in apple orchards under management strategies (organic versus integrated pest management (IPM)). We observed a significant decrease in mass (22 to 27%), inter-eye width (3%), and prothorax width (2 to 5%) in earwigs from IPM compared to organic orchards. Energy body reserves also confirmed these results with a significant decrease of 48% in glycogen and 25 to 42% in lipid content in earwigs from IPM compared to organic orchards. However, the protein content was approximately 70% higher in earwigs from IPM than in organic orchards. Earwigs sampled in IPM orchards may adapt to minimize the adverse toxic effects of pesticide treatments using a large number of strategies, which are reflected in changes to their energy reserves. These strategies could, in turn, influence the population dynamics of natural enemies and impair their role in the biological control of pests in apple orchards.

“…Therefore, these beetles are the objects of numerous toxicity tests. They include not only lethality but also a broad range of effects, including altered activity of enzymes, ultrastructural malformations (Giglio et al, 2017), developmental parameters, mortality (Heimbach, 1998), and population and field effects (Huusela-Veistola, 1996; Markó and Kádár, 2005). Because of their importance in the environment as mentioned above, beetles are also used in standardized tests required for regulatory approval of veterinary and agrotechnical products, and the low toxicity of insecticides to non-target species is one of the crucial points taken under consideration.…”

Beetles as Model Organisms in Physiological, Biomedical and Environmental Studies – A Review

et al. 2019

Model organisms are often used in biological, medical and environmental research. Among insects, Drosophila melanogaster, Galleria mellonella, Apis mellifera, Bombyx mori, Periplaneta americana , and Locusta migratoria are often used. However, new model organisms still appear. In recent years, an increasing number of insect species has been suggested as model organisms in life sciences research due to their worldwide distribution and environmental significance, the possibility of extrapolating research studies to vertebrates and the relatively low cost of rearing. Beetles are the largest insect order, with their representative – Tribolium castaneum – being the first species with a completely sequenced genome, and seem to be emerging as new potential candidates for model organisms in various studies. Apart from T. castaneum , additional species representing various Coleoptera families, such as Nicrophorus vespilloides, Leptinotarsa decemlineata, Coccinella septempunctata, Poecilus cupreus, Tenebrio molitor and many others, have been used. They are increasingly often included in two major research aspects: biomedical and environmental studies. Biomedical studies focus mainly on unraveling mechanisms of basic life processes, such as feeding, neurotransmission or activity of the immune system, as well as on elucidating the mechanism of different diseases (neurodegenerative, cardiovascular, metabolic, or immunological) using beetles as models. Furthermore, pharmacological bioassays for testing novel biologically active substances in beetles have also been developed. It should be emphasized that beetles are a source of compounds with potential antimicrobial and anticancer activity. Environmental-based studies focus mainly on the development and testing of new potential pesticides of both chemical and natural origin. Additionally, beetles are used as food or for their valuable supplements. Different beetle families are also used as bioindicators. Another important research area using beetles as models is behavioral ecology studies, for instance, parental care. In this paper, we review the current knowledge regarding beetles as model organisms and their practical application in various fields of life science.
