Ecotoxicology studies

Since 2010, we have been conducting GLP trials with honeybees (Apis mellifera L.) and other non-target arthropods, offering the following services:

Laboratory studies

  • Acute Oral Toxicity Test. Determination of the LD50 upon contact (OECD 214)
  • Acute Contact Toxicity Test. Determination of the LD50 upon oral exposure (OECD 213)
  • Chronic Toxicity Test. Determination of NOEC (LD50 ) after chronic oral exposure (OECD 245)
  • Larvae Toxicity Test. Determination of the LC50 on larvae repeated exposure (OECD 239)
  • Larvae Toxicity Test. Acute (OECD 237)
  • Bee screening 
  • HPG's

Semi-field studies

They are studies where the aim is to assess the impact of plant protection products on the development of the honey bee brood.

Observation of mortality, flight density, brood development and the behaviour of bee colonies after the exposure of small colonies in tents and tunnels (OECD GC No. 75, EPPO PP 1/170(4)
Tunnel residue trials for MRL setting in Honey (SANTE/11956/2016 rev. 9 Appendix V).

Field studies

Observation of mortality, flight density, development of colonies, brood development and the Behaviour of bee colonies after exposure under field conditions:
EPPO PP 1/170(4).
Phacelia, Oilseed rape, Sunflower, Buckwheat.

Non-target arthropods (NTA)

NTA studies are designed to assess the effects of test item applications on non-target arthropod communities such as insects different to the ones the pesticide is intended to control. These NTA studies can be designed to address specific organism groups or full fauna communities.

We can perform the application, sampling, and classification of insects.

These studies are developed according to the latest EPPO, OECD and BTC methods and guidelines.

Due to our long time relationship with local farmers and an excellent beekeepers, field studies and semi-field test on phacelia and rape or on other crops such as mustard, clover, citrus, peach, plum and sunflower can be conducted. We also have our own beehives with our own beekeeper.

Our special climatic conditions allow us to develop laboratory trials during the whole year, even in winter time.
