Clover cyst nematode, Heterodera trifolii are one of the major pests that damage Chinese cabbage in high land cultivation area and have recently been distributed in Korea. This study was conducted to investigate the effect of temperature and inoculation density on the proliferation of clover cyst nematode. The clover cyst nematode was proliferated at 15-30°C and the egg, female adult and cyst number was the highest at 20°C. As the inoculation density increased, the number of female cyst nematodes increased with the inoculation density and when 16 eggs were inoculated per gram of soil, the amount of growth, number of egg and cyst was the highest. Number of females and eggs were formed more in cabbage than in kale regardless of inoculation density. Chinese cabbage was a favorable host for clover cyst nematode growth than kale.
