通过不同的光照和温度处理三带喙库蚊,解剖观察卵巢,计算滞育率。结果:长日照卵巢平均长度0.99mm,短日照卵巢平均长度0.65mm,临界光周期为每年的9月6日,光照时间为13.25h。这对控制秦皇岛地区晚秋末代的三带喙库蚊有着重要意义。
Culex tritaeniorhynchus was treated with different light and temperature, the ovaries were dissected and the diapause rate was calculated. Results: The average length of ovary in long sunshine was 0.99mm, the average length of ovary in short sunshine was 0.65mm, the critical photoperiod was on September 6 every year, and the light time was 13.25h. This is of great significance to the control of Culex tritaeniorhynchus in the late autumn of Qinhuangdao.
