Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Toxicity to terrestial arthropods:
Aim of this study was to determine the nature of test chemical on the mortality, survival, growth and pupation rate of the larva.
One drop of Triton X-100 was added to 1 ml test chemical and after mixing thoroughly, dilution was effected with water to obtain the desired concentrations. The emulsions were stirred into the diet in a Waring Blendor. Test conducted at 500, 1000, 1500, 2500, 5000 and 10000 mg/l.
Twenty g of the diet was introduced into the bottom of small screw-cap glass jars (base diam and height, 4.5 cm). A 3-cm-diam hole had been cut in the plastic screw-cap and covered with 200-mesh metal wire screen to prevent escape of larvae but provide ventilation. Seven-day-old larvae, each weighing about 3 mg, were introduced into the jars. Larval weight and the pupation rate were the criteria used to evaluate the activity of the different test chemical concentrations. For this the test tubes were examined regularly every second day, larvae were removed and weighed, and mortality was recorded. Based on the mortality rate of test organisms Earias insulana due to the test chemical the LC100 was 10000 mg/l.
