The 'Plant growth test using fly larvae' being a three-component system (diptera, larvae, nutrient substrate + soil and plants) based on the principle of recognizing by the growth of plants as indicator of substances the reduction in performance of fly larvae in the metabolism in soil due to chemicals. Larvae of Musca domestica served as test organisms. As plants, Lepidium sativum, Triticum sativum, Avena sativa, Secale cereale, Phaseolus aureus, Sinapis alba and Medicago sativa were investigated for their suitability as indicators. This is the first time that the possibility is pointed out to recognize by experiments subacute damages within symbioses of a biotope which are due to foreign substances in the environment, at a time far preceding acute disturbances of biocenosis. As part of an updating of the Chemicals Act, the development of sucht test procedures may balance the lack of test results for terrestrial ecosystems which would provide sufficient evidence and can be extrapolated to natural conditions in a biotope
