本文报道了肩胛硬蜱和美洲钝眼蜱成虫的昼夜求偶行为。在田间进行监测，以确定在一天的某些时间和某些环境气象条件下是否会以更高的频率收集蜱虫。温度和相对湿度解释了蜱虫收集的总变化的显着量。虽然这两个物种在每个时期都被收集，但I。在温度较低、相对湿度较高的白天，肩突刺蚁成虫的觅食时间倾向于早一点，晚一点;在上午晚些时候和下午早些时候，在较高的温度和较低的湿度期间，以更大的频率收集美洲。四分之一岛在-0.6 ° C的低温条件下，能观察到肩胛甲的成虫，而在-0.6 ° C的低温条件下，不能观察到肩胛甲的成虫。americanum在4.4°C以下收集。确定了I.本研究中观察到的成年人肩胛肌的平均肌张力低于以前报道的值。这些时间活动模式的影响，疾病传播风险和抽样偏差的评估进行了讨论。
Abstract The diurnal questing behavior of adult Ixodes scapularis Say and Amblyomma americanum (L.) were monitored in the field to determine whether ticks would be collected with greater frequency during certain times of the day and under certain ambient meteorological conditions. Temperature and relative humidity explained a significant amount of the total variation in tick collections. Although both species were collected during every period, I. scapularis adults tended to quest earlier and later in the day when temperatures were lower and relative humidity higher, whereas A. americanum were collected with greater frequency in late morning and early afternoon during periods of higher temperatures and lower humidity. Questing of I. scapularis adults was observed at temperatures as low as -0.6°C, whereas no adult A. americanum were collected below 4.4°C. The questing temperature threshold for I. scapularis adults observed in this study was below that reported previously. The implications of these temporal activity patterns on the assessment of disease transmission risk and sampling bias are also discussed.
