Abstract:In order to enrich population ecology materials of Niviventer fulvescens and provide basis for prediction and control, the population morphological characteristics of Niviventer fulvescens was analyzed statistically in Yuqing county, Cengong county, Leishan county, Kaili city, Guizhou province from 1984 to 2013. The results showed that there was no significant difference in morphological characteristics between female and male. The rodent mainly inhabited in dry farming area, accounting for 3.84% of the total number of rodents, and the average capture rate was 0.19%. There was significant difference in population quantity between different years, and two population quantity peaks was observed in May and October and the average capture rate was 0.27%. The population sex ratio was 0.82, the average pregnancy rate was 27.92%, the average litter size was 5.12, the average uterus streak was 5.36, the average testicular descent rate was 59.89%, and the average reproductive index was 0.65. The population quantity in spring, summer and autumn were significantly higher than in winter. The main reproductive period was March to September. The two population reproductive peaks in March to April and July to August. The main reproductive seasons were spring and summer. In conclusion, April and August are the best prevention and control period. The key prevention and control area is dry farming land.
