ZooKeys 733: 131– 145. https://doi.org/10.3897/zookeys.733.22798 Abstract Gordiids, or freshwater hairworms, are members of the phylum Nematomorpha that use terrestrial de- finitive hosts (arthropods) and live as adults in rivers, lakes, or streams. The genus Paragordius consists of 18 species, one of which was described from the Nearctic in 1851. More than 150 years later, we are describing a second Paragordius species from a unique habitat within the Nearctic; the Madrean Sky Island complex. -
Hairworm Response to Notonectid Attacks

We explored the behavioural response of nematomorph hairworms when their hosts are preyed upon by one of the commonest invertebrate predators in the aquatic habitat of hairworms, notonectids. The hair- worm Paragordius tricuspidatus can alter the behaviour of its terrestrial insect host (the cricket Nemobius syl- vestris), causing it to jump into the water; an aquatic habitat is required for the adult free-living stage of the parasite. We predicted that hairworms whose hosts are captured by a notonectid should accelerate their emergence to leave the host before being killed. As predicted, the emergence length of the worm was sig- nificantly shortened in cases of notonectid predation, but the exact reason of this response seems to be more complex than expected. Indeed, experimental manipulations revealed that hairworms are remark- ably insensitive to a prolonged exposure to predator effluvia which notonectids inject into prey, so accel- erated emergence is not a protective response against digestive enzymes. We discuss other possibilities for the accelerated exit observed, ranging from unspecific stress responses to other scenarios requiring consid- eration of the ecological context. -

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 communica- tion 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 Citation: Mangold, C.A.; Hughes, communication. -
Hairworm Anti-Predator Strategy: a Study of Causes and Consequences

Following the ingestion of the insect host by fish or frogs, the parasitic worm is able to actively exit both its host and the gut of the predator. Using as a model the hairworm, Paragordius tricuspidatus, (parasitizing the cricket Nemobius sylvestris) and the fish predator Micropterus salmoı¨des, we explored, with proteomics tools, the physiological basis of this anti-predator response. By examining the proteome of the parasitic worm, we detected a differential expression of 27 protein spots in those worms able to escape the predator. Peptide Mass Fingerprints of candidate protein spots suggest the existence of an intense muscular activity in escaping worms, which functions in parallel with their distinctive biology. In a second step, we attempted to determine whether the energy expended by worms to escape the predator is traded off against its reproductive potential. -
Two Steps to Suicide in Crickets Harbouring Hairworms

Because water is a limited and critical resource in the ecosystem, we predicted that hairworms should adaptively manipulate host behaviour to maximize parasite reproductive success. Our results sup- ported the hypothesis that the host manipulation strategy of hairworms consists of at least two distinct steps, first the induction of erratic behaviour and then suicidal behaviour per se. Hairworms secured mating by starting to manipulate their host before being fully mature. Once induced, the cricket’s suicidal behaviour was maintained until the host found water but the fecundity of worms decreased over time. As expected, the fecundity of worms was better in crickets with suicidal rather than erratic behaviour. Ó 2008 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd.

Gordiid cysts were found at 70 % (32/46) of sites examined. Based on cyst morphology, we were able to identify three morphological types of gordiid cysts, including Paragordius, Gordius, and Chordodes/Neochordodes. Using our gordiid cyst presence data in conjunction with environmental variables, we developed an ecological niche model using Maxent to identify areas suitable for snail infections with gordiids. -
