The pyrethroide,Fastac 10 EC was tested on the paramecia and Tubifex sp. The results showed that both tests are valid for estimation of the toxicity of the pesticide. However, the Paramecium test is more sensitive when one is investigating the direct toxicity of the compound. The great validity of the Tubifex test lies in the possibility of tracing the teratogenic effects of the pesticides.

Dilutions of Isathrine 10 EC containing in 100 cm3 of water up to 1.25 mg of bioresmethrin were toxic to paramecia, causing 100% mortality immediately or within a few seconds of treatment. In a dilution containing 0.625 mg% of bioresmethrin the mean number of surviving paramecia was 8 after 24 hours' treatment. Lower concentrations posed no threat to paramecia.
