The results showed that soil moisture contents had a significant effect on the emergence rate of C. morulae. When the soil moisture content was 10%,the emergence rate of C. morulae was the highest in both soil types. When the soil moisture content was too high or too low,the emergence rate of C. morulae was significantly reduced. Within the suitable water content range,the emergence rate of C. morulae in sandy soil was significantly higher than that in sandy loam soil. The trend of emergence of C. morulae in the two soil types was basically the same. The number of adults of C. morulae began to increase slowly on March 18,peaked on March 28 and then peaked again on early April.展开更多
