“…The results of the Potter spray tower assay for compounds 8, 9, 10 and 11 were summarized in Table 3. Erythraline (11) was the most potent compared with the other three aphicidal compounds, although its potency (LC 50 , 112.78 μg ml -1 ) was obviously lower than that of imidacloprid (45.40 μg ml -1 ).…”

“…The most potent compound, erythraline (11), was chosen to investigate the effect on enzyme activities in A. gossypii at 58.80 μg ml -1 (LC 25 ), 112.78 μg ml -1 (LC 50 ) and 216.40 μg ml -1 (LC 75 ). Aphids were treated with the above concentrations of erythraline (11) by Potter spray tower as described above.…”

“…However, long‐lasting application of these synthetic aphicides over past decades has led to the development of pesticide resistance in several aphid species . In coping with resistant strains, the continued use of insecticides poses substantial deleterious hazards to the environment, including pesticide residues and toxicity to non‐target organisms, such as mammals and beneficial insects (natural predators, pollinators, and parasitoids) . Therefore, there is a great demand for efficient and environmentally friendly pest control approaches as alternatives to the synthetic pesticides used currently.…”

“…The influence of xenobiotics on earthworm populations, even at low doses recommended by the manufacturers as safe, can be very different (Alves et al 2013;Uhl et al 2015;Garczyńska et al 2018). In relation to this, there is a need for a broader assessment of the effect of NEO on soil fauna under varying environmental conditions.…”

In the laboratory experiment, the effect of neonicotinoid Nuprid 200SC at the dose recommended by the manufacturer on the dynamics of population of earthworms Dendrobaena veneta was assessed. The studies were conducted on mature D. veneta specimens, in 4 replications of beddings (control, insecticide) in the climatic chamber. Condition of the population was checked five times, using a method of manual segregation of beddings. Insecticide limited the increase in number and biomass of D. veneta population (both the whole population, mature specimens and immature earthworms), but also restricted its reproduction (it decreased the number of cocoons laid by earthworms (p<0.05)).

“…Mostly they were used to focus on impacts on intra-or interspecific competition (one trophic level; Foit et al 2012a;Dolciotti et al 2014;Del Arco et al 2015;Viaene et al 2015) or on consumer-resource relationships (2 trophic levels) with herbivore-producer (Daam and Van Den Brink 2007) or predator-prey interactions (Barry and Davies 2004;Liebig et al 2008;Englert et al 2012). Tritrophic systems are frequently used in terrestrial research, for example, in plant-herbivore-parasite systems (Bredeson et al 2015;Uhl et al 2015), but few small test systems exist to assess direct and indirect impacts at the population and community levels in the aquatic environment. Test formats include simulations of microbial detritus food chains (producerconsumer-decomposer [Fuma et al 2000;Dawoud et al 2017]) and producer-consumer communities with either invertebrate predators (Barry and Davies 2004) or vertebrate predators (Metcalf et al 1971).…”

Chemical impacts on the environment are routinely assessed in single-species tests. They are employed to measure direct effects on nontarget organisms, but indirect effects on ecological interactions can only be detected in multispecies tests. Micro- and mesocosms are more complex and environmentally realistic, yet they are less frequently used for environmental risk assessment because resource demand is high, whereas repeatability and statistical power are often low. Test systems fulfilling regulatory needs (i.e., standardization, repeatability, and replication) and the assessment of impacts on species interactions and indirect effects are lacking. In the present study we describe the development of the TriCosm, a repeatable aquatic multispecies test with 3 trophic levels and increased statistical power. High repeatability of community dynamics of 3 interacting aquatic populations (algae, Ceriodaphnia, and Hydra) was found with an average coefficient of variation of 19.5% and the ability to determine small effect sizes. The TriCosm combines benefits of both single-species tests (fulfillment of regulatory requirements) and complex multispecies tests (ecological relevance) and can be used, for instance, at an intermediate tier in environmental risk assessment. Furthermore, comparatively quickly generated population and community toxicity data can be useful for the development and testing of mechanistic effect models.
