抽象的。1从两个越冬种群采集的白纹金斑蝶(Danaus Plexippus)鳞片上有圆孢子虫孢子的比例在53%~68%之间。在不同地点之间和整个冬季，携带赤眼蜂孢子的蝴蝶的频率保持不变。2从蝴蝶身体各处采集到的孢子以腹部最多，尤其是在后三分之一附近。3有孢子的蝴蝶在10.1°C±0.4SE和78.3%的相对湿度下存活的时间与未检测到孢子的蝴蝶一样长。±0.6SE。昆虫孢子的温度为19.4℃±0.4SE，相对湿度为44.9%。±1.5Se的失水率明显高于未检出孢子的帝王蝶，存活时间明显短于未检出孢子的帝王蝶。
Abstract. 1 Monarch butterflies, Danaus plexippus, from two overwintering populations, were found to have Ophryocystis elektroscirrha spores on their scales at rates between 53% and 68%. The frequency of butterflies with O.elektroscirrha spores remained about the same between sites and throughout the winter. 2 The spores, recovered from all parts of the body of the butterfly, were most numerous on the abdomen, particularly near the posterior third. 3 Butterflies with spores survived as long as those without detectable spores at 10.1°C ±0.4 SE and 78.3% r.h. ±0.6SE. Insects with spores held at 19.4°C ±0.4SE and 44.9% r.h. ±1.5SE showed a significantly higher rate of moisture loss and survived a shorter period than monarch butterflies without detectable spores.
