“…Sometimes, such parasite-modified behaviour changes the spatial distribution of the host population (e.g. Helluy 1984;Curtis 1987;Thomas et al 1998;Kuris 2005). Altering the spatial distribution of hosts can affect intra and interspecific interactions of the host population (Thomas et al 1998;Ponton et al 2005), and potentially affect the surrounding community (Thomas et al 1998(Thomas et al , 1999Mouritsen & Poulin 2005).…”

Parasites alter host phenotype and may create a new ecological niche for snail hosts

By modifying the behaviour and morphology of hosts, parasites may strongly impact host individuals, populations and communities. We examined the effects of a common trematode parasite on its snail host, Batillaria cumingi (Batillariidae). This widespread snail is usually the most abundant invertebrate in salt marshes and mudflats of the northeastern coast of Asia. More than half (52.6%, nZ1360) of the snails in our study were infected. We found that snails living in the lower intertidal zone were markedly larger and exhibited different shell morphology than those in the upper intertidal zone. The large morphotypes in the lower tidal zone were all infected by the trematode, Cercaria batillariae (Heterophyidae). We used a transplant experiment, a mark-and-recapture experiment and stable carbon isotope ratios to reveal that snails infected by the trematode move to the lower intertidal zone, resume growth after maturation and consume different resources. By simultaneously changing the morphology and behaviour of individual hosts, this parasite alters the demographics and potentially modifies resource use of the snail population. Since trematodes are common and often abundant in marine and freshwater habitats throughout the world, their effects potentially alter food webs in many systems.

“…In G. insensibilis, the parasite induces behavioural changes such that the infected amphipod becomes photophilic, prefers to swim closer to the water surface, and becomes hyperactive when confronted with an avian predator (Helluy, 1983;Helluy & Thomas 2003). These behavioural changes have been found to increase susceptibility of G. insensibilis to predation by bird definitive hosts (Helluy, 1984). However, in the case of G. aequicauda, behavioural changes only occur if the amphipod is infected during its juvenile stage (Helluy, 1983).…”

“…Helluy, 1983;Kunz & Pung, 2004), we expected M. novaezealandensis to be capable of manipulating the behaviour of its other second intermediate hosts, such as the amphipod P. novizealandiae. Predation of amphipods by avian definitive hosts occurs at low tide in shallow water puddles; amphipod activity and vertical distribution are not only traits likely to determine predation rates, they are also targets of manipulation in other microphallid-crustacean systems (Helluy, 1983(Helluy, , 1984Kunz & Pung, 2004). These are therefore the behavioural traits investigated here.…”

Effects of the trematode Maritrema novaezealandensis on the behaviour of its amphipod host: adaptive or not?

There are many recorded cases of parasites that are capable of altering the behaviour of their host to enhance their transmission efficiency. However, not all of these cases are necessarily the results of the parasites actively manipulating host behaviour; they may rather be the ‘by-products’ of pathology caused by the parasite's presence. This study investigates the effect of the microphallid trematode Maritrema novaezealandensis on the behaviour of one of its crustacean intermediate hosts, the amphipod Paracalliope novizealandiae. Uninfected amphipods were experimentally infected by exposure to M. novaezealandensis cercariae. The activity level and vertical position of experimentally infected amphipods were compared with uninfected amphipods at 2 weeks and 6 weeks post-infection, i.e. both before and after the parasite achieved infectivity to its definitive host. Infected amphipods were found to exhibit significantly lower levels of activity and to occur significantly lower in the water column than uninfected controls during both periods. Based on the timing of the change in behaviour exhibited by infected amphipods, the results suggest that the altered behaviour exhibited by P. novizealandiae infected with M. novaezealandensis is most likely due to pathology caused by the parasite rather than a case of active, and adaptive, behavioural manipulation.

“…Additionally, the parasitic worms Euhaplorchis californiensis and Microphallus papillorobustus infect and alter the behavior of killifish and gammarids, respectively, causing changes in behavior that increase the probability of consumption by terminal hosts (Table 1). These latter changes in behavior are hypothesized to be triggered by changes in monoamine signaling in the host [19,20,[95][96][97][98][99][100].…”

Many organisms are able to elicit behavioral change in other organisms. Examples include different microbes (e.g., viruses and fungi), parasites (e.g., hairworms and trematodes), and parasitoid wasps. In most cases, the mechanisms underlying host behavioral change remain relatively unclear. There is a growing body of literature linking alterations in immune signaling with neuron health, communication, and function; however, there is a paucity of data detailing the effects of altered neuroimmune signaling on insect neuron function and how glial cells may contribute toward neuron dysregulation. It is important to consider the potential impacts of altered neuroimmune communication on host behavior and reflect on its potential role as an important tool in the “neuro-engineer” toolkit. In this review, we examine what is known about the relationships between the insect immune and nervous systems. We highlight organisms that are able to influence insect behavior and discuss possible mechanisms of behavioral manipulation, including potentially dysregulated neuroimmune communication. We close by identifying opportunities for integrating research in insect innate immunity, glial cell physiology, and neurobiology in the investigation of behavioral manipulation.
