摘要
二齿新蚤和方形黄鼠蚤松江亚种在温度5～35℃范围内,寿命与温度呈直线负相关。二齿新蚤在相对湿度90％以下时,寿命与湿度呈直线正相关。方形黄鼠蚤松江亚种在相对湿度70％以下时,寿命与湿度呈直线正相关;在70％以上时,呈直线负相关。
1. In Neopsylla bidentatiformis (Wagner, 1893) and Citellophilus tesquorum sungaris (Jordan, 1929), relation between life duration and temperature (5-35 ℃ ) manifested alinear negative correlation. The higher the temperature goes up, the shorter the life duration of the fleas.2. At the relative humidity (RH) of 90% and below, life duration of Neopsylla bidentatiformis was positively correlated with RH, and the same was true for Citellophilus tesquorum sungaris when RH was at 70% and below. It was suggested therefore, optimal RH was 90% for the former flea and 70% for the latter, and relation between life duration and relative humidity was a linear positive correlation before the optimal RH and linear negative after the optimal RH.
