对在纽约沿海地区发现的三种硬蜱进行了非协调活动阈值温度和活动阈值温度的检测，其中温度低于该温度时，壁虱不能再以协调的方式寻找宿主。测定了肩部若虫、雌、雄、若虫、雌、雄Amblyomma americanum(L.)和雌、雄变形皮(Say)的平均不协调活动阈值和活动阈值温度。只有成虫的不协调活动阈值和活动阈值温度与温度下降速率显著相关。平均非协调活动阈值和活动阈值温度与每个种类的平均大小显著相关。
Uncoordinated activity threshold temperature, the temperature below which ticks can no longer seek a host in a coordinated manner, and the activity threshold temperature, when all activity ceases, were examined for three species of ticks found in coastal sections of New York. The mean uncoordinated activity threshold and activity threshold temperatures were determined for nymphal, female and male Ixodes scapularis Say, nymphal, female, and male Amblyomma americanum (L.), and for female and male Dermacentor variabilis (Say). Only the uncoordinated activity threshold and activity threshold temperatures for adult I. scapularis were significantly correlated to the rate of temperature decrease. The mean un coordinated activity threshold and activity threshold temperatures were significantly correlated to the mean size of each tick species.
