“…Chemoreception is a major sensory modality in all arthropods and chemical cues are of fundamental importance in locating food, hosts and mates, for example, in decapods (Grasso & Basil 2002; Keller, Powell & Weissburg 2003) and copepods (Strickler 1998; Weissburg & Doall 1998; Mordue (Luntz) 2003; Pino‐Marambio et al. 2007).…”

Ectoparasitic sea lice are the most important parasite problem to date for the salmon farming industry in the northern and southern hemispheres. An understanding of host location in the specialist species, Lepeophtheirus salmonis, the most important louse species in the North Atlantic, is now being realized using behavioural in vitro and in vivo bioassays coupled with chemical analysis of fish conditioned waters. Both physical and chemical cues are important in host location. Responses of sea lice to physical cues such as light and salinity may enable them to gather in areas where host fish are likely to be found. Mechanoreception is an important sensory modality in host location and acts by switching on specific behaviours that enable landing on a fish. Chemoreception plays a defining role in host location and recognition. The detection of host kairomones switches on 'host search' behavioural patterns and also induces landing responses whereas non-host kairomones fail to induce attraction or significant landing behaviour. Semiochemicals derived from salmon and also non-host fish have been identified, and may prove useful for the development of integrated pest management strategies, by the introduction of odour traps for monitoring lice numbers, and by the use of stimulo-deterrent diversionary (push:pull) strategies in their control.

“…Most of the published literature on 1-octen-3-ol concerns either its properties as a mushroom flavor compound (Zawirska-Wojtasiak 2004) or its importance in attracting biting insects (Bernier et al 2000; Luntz 2001). In both of these cases, the R enantiomer (“roctonal”) is the active component.…”

“…In addition to fungi, this VOC is detected from a widespread group of animals and plants (Bernier et al 2000; Ramoni et al 2001; Maggi et al 2010). In insects, it functions as a signaling molecule (semiochemical), especially in mediating host location cues for flies, mosquitoes, and mites where it orients biting flies and other blood-sucking arthropods to their hosts (Luntz 2001). Along with CO 2 it is the compound that attracts malaria mosquitoes and can be used as a bait in mosquito traps (Nilssen 1998).…”

“Mushroom alcohol,” or 1-octen-3-ol, is a common fungal volatile organic compound (VOC) that has been studied for its flavor properties, its effects on fungal spore germination, mushroom development, and as a signaling agent for insects. Far less is known about its effects on plants. We exposed Arabidopsis thaliana seeds, under conditions conducive to germination, to high (10 and 100 mg/1) and low concentrations (1, 2, and 3 mg/1) of racemic, S, and R forms of 1-octen-3-ol for 3 days. In addition, 1-, 2-, 3-, and 4-week-old A. thaliana plants also were exposed to 1 mg/1 of the compounds for the same period of time. Seedling formation was retarded with all tested levels of exposure to 1-octen-3-ol for both enantiomers and the racemer, while 95% of unexposed control seeds germinated to seedling within 3 days. There was a dose-dependent response in the reduction of seedling formation between 1 mg/1 and 3 mg/1 of exposure. When exposed seeds were removed from the VOC, nearly all resumed germination. Young plants exposed to 1 mg/1 of the R and S enantiomers of 1-octen-3-ol exhibited a mild inhibition of growth and chlorophyll production at 2 and 3 weeks but not at 4 weeks.

“…Semiochemicals are naturally occurring behaviour‐modifying chemicals that are used by a range of arthropods in chemical communication to locate a host, mate or oviposition site (Mordue (Luntz) );. The use of semiochemicals for pest control in agriculture is well established, for example as part of a push‐pull strategy where pests are pushed away from crops and pulled towards traps or targets, where they are removed from the environment (Cook, Khan & Pickett ; Hassanali et al .…”

The potential for developing botanically derived natural products as novel feed-through repellents for disrupting settlement of the salmon louse, Lepeophtheirus salmonis (Caligidae) upon farmed Atlantic salmon, Salmo salar, was investigated using an established laboratory vertical Y-tube behavioural bioassay for assessing copepodid behaviour. Responses to artificial sea water conditioned with the odour of salmon, or to the known salmon-derived kairomone component, α-isophorone, in admixture with selected botanical materials previously known to interfere with invertebrate arthropod host location were recorded. Materials included oils extracted from garlic, Allium sativum (Amaryllidaceae), rosemary, Rosmarinus officinalis (Lamiaceae), lavender, Lavandula angustifolia (Lamiaceae), and bog myrtle, Myrica gale (Myricaceae), and individual components (diallyl sulphide and diallyl disulphide from garlic; allyl, propyl, butyl, 4-pentenyl and 2-phenylethyl isothiocyanate from plants in the Brassica genus). Removal of attraction to salmon-conditioned water (SCW) or α-isophorone was observed when listed materials were presented at extremely low parts per trillion (ppt), that is picograms per litre or 10 level. Significant masking of attraction to SCW was observed at a level of 10 ppt for diallyl disulphide and diallyl sulphide, and allyl isothiocyanate and butyl isothiocyanate. The potential of very low concentrations of masking compounds to disrupt Le. salmonis copepodid settlement on a host fish has been demonstrated in vitro.
