In Korea very few studies have been conducted in relation to collembola sensitivity to pollutants in populations exposed to soil contaminants in particular heavy metals. The objective of the current research were to study the thermal effects of selected heavy metals on the survival and reproduction of P. rosea in order to assess its applicability as a test species. Petri dishes (87 mm diameter, 15 mm height) were used for compact soil toxicity test and were filled to a depth of 0.5 mm with 6 g artificial soil and 3.5 mL distilled water was added. 20 adults (6 weeks from egg stage) were introduced to each petri dish and placed in two incubators set at 20℃ and 25℃, respectively under continuous darkness. The 28 days EC50s for cadmium in compact soil at 20℃ and 25℃ were 48.9031 and 91.3585 mg/kg, respectively. This thermal toxicity test of P. rosea is advantageous for various environmental sudies, such as toxicity tests.
