“…The manipulated ladybird is then turned into a bodyguard (sensu Maure et al, 2013) that contributes to reduce mortality from natural enemies during parasitoid pupation. The length of the manipulation period is negatively correlated with D. coccinellae fecundity (Fig.1C), suggesting that the parasitoid cannot concomitantly allocate maximal resources for both its reproduction and protection.…”

SummaryAlthough host manipulation is likely to be costly for parasites, we still have a poor understanding of the energetic aspects underlying this strategy. It is traditionally assumed that physiological costs are inevitably associated with mechanisms evolved by parasites to induce the required changes in host behaviours. While most energetic expenditures of parasites relate primarily to bringing about the altered behaviours, manipulative parasites also have to consider the condition of their host during the manipulation. Here, we suggest that because of this trade-off, the energy required to accomplish parasite-induced behaviours may represent a key energetic constraint for parasites. Depending on the energetic expenditures specific to each type of manipulation, parasites should undergo selection to secure resources for their host to allow them to perform manipulated behaviours.

Who is the puppet master? Replication of a parasitic wasp-associated virus correlates with host behaviour manipulation

Many parasites modify their host behaviour to improve their own transmission and survival, but the proximate mechanisms remain poorly understood. An original model consists of the parasitoid Dinocampus coccinellae and its coccinellid host, Coleomegilla maculata; during the behaviour manipulation, the parasitoid is not in contact with its host anymore. We report herein the discovery and characterization of a new RNA virus of the parasitoid (D. coccinellae paralysis virus, DcPV). Using a combination of RT-qPCR and transmission electron microscopy, we demonstrate that DcPV is stored in the oviduct of parasitoid females, replicates in parasitoid larvae and is transmitted to the host during larval development. Next, DcPV replication in the host's nervous tissue induces a severe neuropathy and antiviral immune response that correlate with the paralytic symptoms characterizing the behaviour manipulation. Remarkably, virus clearance correlates with recovery of normal coccinellid behaviour. These results provide evidence that changes in ladybeetle behaviour most likely result from DcPV replication in the cerebral ganglia rather than by manipulation by the parasitoid. This offers stimulating prospects for research on parasitic manipulation by suggesting for the first time that behaviour manipulation could be symbiont-mediated.

“…Examples of conditionally helpful parasites include instances where parasites limit the ability of new and potentially more harmful parasites to establish in the host (Haine, Boucansaud, & Rigaud, 2005;Mideo, 2009), provide hosts with a competitive advantage (Kusch & G€ ortz, 2006), protect against abiotic stressors (Duncan et al, 2010;S anchez et al, 2016;Sures, 2003Sures, , 2008, improve host antipredator behaviour towards predators in instances where parasites could not survive transmission to these predators (Maure, Daoust, Brodeur, Mitta, & Thomas, 2013;M edoc, Rigaud, Bollache, & Beisel, 2009;Parker et al, 2009;Weinreich, Benesh, & Milinski, 2013), or increase reproductive success (Dass et al, 2011;Haine et al, 2004). These benefits can come in the form of novel functions to the host (e.g.…”

Better with your parasites? Lessons for behavioural ecology from evolved dependence and conditionally helpful parasites

Interest in how parasites shape host behaviour has increased dramatically in recent years. The main focus of behavioural ecologists has been on the negative effects of parasites on host behaviour. However, there are instances in which infected hosts express more adaptive behavioural phenotypes and have higher fitness relative to uninfected hosts, suggesting that it is sometimes beneficial to be parasitized. For example, hosts can exhibit evolved dependence, wherein the host coevolves with and comes to depend on parasites for the expression of adaptive host behaviours. Additionally, 'conditionally helpful parasites' modify the host phenotype in ways that benefit the host under particular conditions. These scenarios have been explored in the context of bacterial or fungal symbionts, but have been relatively unstudied with regard to metazoan parasites (e.g. trematodes, acanthocephalans, nematodes and cestodes). We explore how these scenarios apply to hosts infected by metazoan parasites, and consider implications for research in behavioural ecology. We examine conditions under which infection should result in more adaptive host behavioural phenotypes, and the implications for host fitness and evolution. We then discuss the implications of conditionally helpful parasites and parasites for which hosts have evolved dependence for laboratory studies of host behaviour and for conservation and reintroduction programmes.
