Efficacy evaluation of pesticides

Insect Services offers support with the registration of biocides according to the Biocidal Product Regulation (ECHA BPR Efficacy Guidance Vol.II (2018)).

We test insecticides, acaricides, repellents and attractants (product groups PT 18 and 19) according to international standards of the US Environmental Protection Agency (EPA) and guidelines such as the Technical Notes of Guidance (TNsG) of the European Commission or guidelines of the World Health Organization (WHO) and the Organisation for Economic Co-operation and Development (OECD) and others.

We have developed a number of bespoke test systems that are specifically designed for the species we work with. If there are no suitable test systems available for specific demands, we can develop our own standards. For example, we developed an effective test for evaluating tick repellents that is highly standardized and yet yields results that are quite close to results obtained when using human volunteers. We also offer testing of ready-to-use products under field conditions outside the lab.
We provide established test systems for the following target organisms:

  • Ticks
    • Ixodes ricinus (Castor bean tick)
    • Dermacentor reticulatus (Meadow tick)
    • Dermacentor marginatus (Ornate sheep tick)
    • Rhipicephalus sanguineus (Brown dog tick)
    • Ixodes persulcatus (Taiga tick)
  • Moths
    • Tineola bisselliella (Clothes moth)
    • Plodia interpunctella (Indian meal moth)
  • Flies
    • Musca domestica (Common house fly)
  • Cockroaches
    • Blattella germanica (German cockroach)
    • Periplaneta americana (American Cockroach)
  • Lice
    • Pediculus humanus (Clothes louse)
  • Mites
    • Dermatophagoides pteronyssinus (House dust mite)
    • Neotrombicula autumnalis (Chigger mite)
    • Dermanyssus gallinae (Poultry red mite)
  • Silverfish
    • Lepisma saccharina (Silverfish)
  • Fur beetles
    • Attagenus unicolor (Black carpet beetle)
  • Ants
    • Lasius niger (Black garden ant)
