熊蜂幼虫没有表现出任何迹象，Crithidia bombi感染。B。terrestris幼虫能够将寄生虫传播给未感染的工人。巢工相互作用可能是社会性昆虫疾病网络的一个组成部分。疾病传播网络是了解寄生虫流行病学的关键。在社会性昆虫中，结构化的接触网络被认为可以限制疾病传播到社会中的脆弱成员，如女王或育雏。然而，即使是这些复杂的社会结构也不能提供完全的保护，因为一些疾病，这些疾病是由工人在育雏期间传播的，仍然可以感染育雏。鉴于在群居昆虫群体中发生的高比率的进食相互作用，幼虫可能充当疾病传播中心。在这里，我们使用熊蜂熊蜂和它的寄生虫Crithidia bombi，以确定在熊蜂疾病传播网络的育雏的作用。人工接种C. bombi在接种后7天没有出现感染迹象。然而，接受人工接种或育雏工人污染饲料的幼虫能够将寄生虫传播给幼稚的工人。这些结果表明，发展中的育雏是一个潜在的途径，结肠内疾病的传播，并应包括在考虑社会昆虫疾病传播网络。
Bombus terrestris larvae showed no signs of Crithidia bombi infection. B. terrestris larvae were able to transmit the parasite to naive workers. Brood-worker interactions may be a component of social insect disease networks. Disease transmission networks are key for understanding parasite epidemiology. Within the social insects, structured contact networks have been suggested to limit the spread of diseases to vulnerable members of their society, such as the queen or brood. However, even these complex social structures do not provide complete protection, as some diseases, which are transmitted by workers during brood care, can still infect the brood. Given the high rate of feeding interactions that occur in a social insect colony, larvae may act as disease transmission hubs. Here we use the bumblebee Bombus terrestris and its parasite Crithidia bombi to determine the role of brood in bumblebee disease transmission networks. Larvae that were artificially inoculated with C. bombi showed no signs of infection seven days after inoculation. However, larvae that received either an artificial inoculation or a contaminated feed from brood-caring workers were able to transmit the parasite to naive workers. These results suggest that the developing brood is a potential route of intracolonial disease transmission and should be included when considering social insect disease transmission networks.
