虽然性传播病原体和寄生虫在昆虫和其他动物身上很常见，但影响其发病率的因素目前尚不确定。为了了解在确定性传播寄生虫存在的重要因素，这将是有帮助的，有种内变异的发病率的信息，因为这种变化的原因可能反映了跨物种的性传播寄生虫的存在/不存在的可能原因。因此，我们映射的发病率的寄生虫Coccipipus coccidamiae在欧洲的主要宿主，瓢虫Adalia bipunctata。我们观察到C.该属在中欧、南欧和东欧广泛分布，但在北欧和西北部种群中不存在。这种模式的发病率变化的原因进行了讨论，特别是参考主机的化性。我们还注意到C.紫堇属A. bipunctata与该物种的另一种性传播寄生虫Hesperomyces virescens不一致。
Whilst sexually transmitted pathogens and parasites are common on insects and other animals, the factors affecting their incidence are currently uncertain. In order to understand the factors important in determining the presence of sexually transmitted parasites, it would be helpful to have information on intraspecific variation in incidence, as the causes of this variation are likely to reflect the likely causes of the presence/absence of sexually transmitted parasites across species. We therefore mapped the incidence of the parasite Coccipolipus hippodamiae within Europe on its primary host, the ladybird Adalia bipunctata. We observed that C. hippodamiae was present widely in Central, Southern and Eastern Europe, but was absent from northerly and north-western popula- tions. The cause of this pattern of incidence variation is discussed, with particular reference to the voltinism of the host. We also note that the distribution of C. hippodamiae on A. bipunctata is not congruent with that of another sexually transmitted parasite of this species, Hesperomyces virescens.
