..., 1962 ; Guedes et al., 2012). CO 2 is a kairomone used by many hematophagous parasites to sense the proximity of a potential host (Chaisson and Hallem, 2012). For instance, CO 2 exposure elicits a range of contextual effects in various mosquito species that are thought to promote host-seeking...

... is processed by prey sensory systems. To explore these issues, we exposed Rana dalmatina embryos to dragonfly chemical cues (kairomones) up to hatching. At different times after hatching (up to 40 days), we recorded morphology and anti-predator behaviour of tadpoles from control and kairomone-treated embryo...

... (Huettel, 1986 ; Riga, 2004). A kairomone is an allelochemical that elicits a positive response from the receiving organism. Although many nematodes form phoretic or parasitic associations with insects, very little information is available on kairomones other than CO 2 with regard to direct host...
