Ecotoxicology - Terrestrial

IES Ltd offers a complete spectrum of bee, NTA and NTP laboratory and field studies and is also specialised in conducting higher-tier studies.

Team Experience

Our expert team has extensive and long-term experience in conducting studies with bees, non-target arthropods, soil organisms and non-target plants, either under laboratory, semi-field or field conditions.

Laboratory Bee Studies

IES Ltd performs laboratory studies on pollinating insects (honey bees, bumble bees, solitary bees) to assess acute or chronic effects of plant protection products. Study types include acute oral and contact toxicity as well as chronic toxicity to adult bees and in vitro acute and chronice toxicity to bee larvae.

Semi-field Tunnel and Field Bee Studies

Since IES Ltd is located in the countryside, direct access to experimental fields in the proximity of the facility is granted. We perform Oomen, semi-field and field studies with pollinating insects including honey bees, bumble bees and solitary bees. The effects of plant protection products on mortality, behaviour and brood development using digital assessment are investigated and performed routinely. One of IES Ltd’s key expertises and advantages is the combination of (semi-) field bee studies with the analytical measurement of residues in different matrices like pollen, honey and nectar.

Non-target Arthropod Studies

We conduct Tier I to Tier III studies on non-target arthropods with plant- and soil-dwelling organisms including, but not limited to, Typhlodromus pyri, Aphidius rhopalosiphi, Chrysoperla carnea, Coccinella septempunctata and Aleochara bilineata. The aim of these laboratory, semi-field or field studies is to assess potential side effects of plant protection products on mortality and reproduction of these test species.

Soil Organism Studies

We perform laboratory and field studies with several soil organisms including earthworms (Eisenia fetida), predatory mites (Hypoaspis aculeifer) and Collembola (Folsomia candida) to assess potential acute and chronic effects of chemicals. We are prepared for conducting these studies including corresponding analytical verifications, further on tailor made higher Tier approaches are feasible. Please contact us for more information

Non-target Plant Studies

Non-target plant studies (seedling emergence, vegetative vigour and chronic plant studies) are either carried out either in the greenhouse or under semi-field conditions to investigate acute or chronic effects of chemicals on seedling emergence of seedlings and the growth and reproduction of plants. Tests including up to 10 different species and in line with most recent guidance developments and requirements are possible. Please contact us for more information.

Dung Organism Studies

We offer testing of the two dung fly species Musca autumnalis and Scathophaga stercoraria as well as the dung beetle species Aphodius constans, including corresponding analytical verification. Furthermore, we are prepared for testing other species (e.g. Onthophagus spec.) or tailor-made higher tier approaches. As well as the laboratory testing, we are able to prepare environmental risk assessments according to the requirements of EMA and CVMP. Please contact us for more information.
