“…Its clastogenic potential has also been tested on human lymphocytes and rat bone-marrow cells [76]. In invertebrates, laboratory tests have shown that exposure to pendimethalin causes mortality in male wasps [17], disrupts reproducing capability in springtails, and reduces growth in earthworms [16]. In our study, we observed a depletion of circulating hemocytes at two days after initial exposure.…”

“…Because of its low affinity for animal tubulins, the effects of pendimethalin have mainly been investigated in soil microbiota [12]. Very few studies have addressed potential toxicity following the application of sublethal doses of pendimethalin on a low number of aquatic organisms [11,14,15], as well as on non-target soil invertebrates, including insects [16,17]. This raises the question of whether exposure to pendimethalin may be harmful and can cause potential direct (feeding on contaminated prey or absorption by contact) and indirect (depletion of food) effects on non-target species.…”

Continuous Agrochemical Treatments in Agroecosystems Can Modify the Effects of Pendimethalin-Based Herbicide Exposure on Immunocompetence of a Beneficial Ground Beetle

Herbicide application for pest control can negatively affect soil biodiversity, mainly acting on species that are involved in ecosystem service. In this study, field and laboratory trials were designed to assay herbicide exposure effects on the constitutive immunity of Harpalus (Pseudoophonus) rufipes (De Geer, 1774), a beneficial carabid species that inhabits croplands. The circulating hemocytes (THCs) and plasmatic levels of basal and total phenoloxidase (PO), as well as lysozyme-like enzyme activities, were measured as markers of exposure. In laboratory tests, the exposure to realistic field doses of pendimethalin-based herbicides for two, seven and 21 days caused a reduction in enzyme activities in beetles from organic crops. In beetles from conventional fields, the THCs and total PO activity decreased significantly at two and seven days after the initial exposure, though no effects were recorded on basal PO and lysozyme like-enzyme activities. These differences in enzyme activities and THCs indicate that the interference of pendimethalin with immune parameters clearly depends on both the different field conditions from which the population comes and the cumulative effects of repeated applications over the time.

“…As reference controls, ten soil containers with non-GM maize were fortified to 2.25 mg of pendimethalin in 100 µl acetone (90 µg pendimethalin/g soil) one day before starting the assay. Pendimethalin is a dinitroaniline herbicide, and its toxicity to springtail has been well-characterized in previous studies (Belden 2005, Clark 2006). In addition to three treatments with maize, a no-maize (soil only) treatment was also prepared.…”

“…A day before adding earthworms, 22.5 mg of pendimethalin diluted in 200 µl acetone was spiked to ten non-GM maize-containing soil-manure mixtures as reference controls (900 µg pendimethalin/g soil-manure mixture). Toxicity of pendimethalin to earthworm survival and growth was characterized in previous studies (Belden 2005, Clark 2006). Additionally, ten no-maize (soil-manure mixture only) treated samples were also prepared.…”

“…If the host plant is grown in aquatic systems, such as paddy rice, or the cropping field is close to a waterway, the entry of recombinant proteins into an aquatic ecosystem and their effects on aquatic organisms would be a further concern relative to the ecological risks of PMPs. As reviewed by Clark et al (2005) for maize-expressed Bt insecticidal proteins, the inadvertent exposure of non-target organisms to recombinant proteins is an important aspect of the ecological risk assessment. To undertake ecological risk assessment for PMPs, it is critical to characterize the ecotoxicological hazard and the probability of exposure through the quantitative understanding of the fate and effects of recombinant protein in the surrounding environment (Wachbroit 1991).…”

Pesticides are a major concern because of their deleterious impacts on biodiversity and on the ecological functions provided by living organisms. Although earthworms are well studied, smaller-sized organisms, such as Collembola, also contribute to the agroecosystem functioning, and their sensitivity to pesticides makes them good bioindicators of soil quality. Using data from 21 publications, we performed a meta-analysis to compare the pesticide sensitivity of Collembola with other soil invertebrate groups and discuss the relevance of including tests on representatives of this microarthropods group in European regulation tests. We defined a paired observation as the median lethal concentration or the median effect concentration values for both Collembola species and another soil fauna group (Acari, enchytraeids, earthworms, isopods, and nematodes) under a unique combination of author, year, substance, and type of soil (61 and 57 paired observations for reproduction and lethal effects). In some studies, paired comparisons were available for several groups of soil fauna. We demonstrated that Collembola are among the most sensitive soil fauna groups to a variety of pesticides, notably for effects on reproduction, mostly compared with earthworms and enchytraeids. Because there are several modes of exposure and explaining factors, we suggest moving from a single-species study to a food-chain approach integrating different taxonomic groups. Differences between soil fauna groups in sensitivity or response to pesticides could have effects on soil communities and also on soil functions.
