The effect of the temperature on the transovarial passage of Babesia bigemina has been studied in female Boophilus annulatus during their oviposition. Kinetes of Babesia were present in eggs laid at the temperatures of 16, 20, 26, 28, 30 and 35 degrees C. The rate of infection was temperature dependent. It reached at least 50%, even at low temperatures. The average infection level at 26 and 30 degrees C was 270 kinetes per egg. However, between 20 and 35 degrees C the eggs laid during the first 3 days were parasite free. At 16 degrees C, no kinetes were detected during the first 13 days of oviposition.
在环形牛蜱雌蜱产卵期间，研究了温度对双芽巴贝斯虫经卵传递的影响。在16、20、26、28、30和35摄氏度下产下的卵中存在巴贝斯虫动合子。感染率取决于温度。即使在低温下，感染率也至少达到50%。26和30摄氏度时的平均感染水平为每个卵270个动合子。然而，在20至35摄氏度之间，头3天产下的卵未感染寄生虫。在16摄氏度时，产卵的前13天未检测到动合子。
