The Roles of Vision and Antennal Olfaction in Enemy Avoidance by Three Predatory Heteropterans

Role of Vision and Antennal Olfaction in Habitat and Prey Location by Three Predatory Heteropterans

“…Because antennal olfaction appears to be the primary sensory mechanism by which these predators locate prey, it is interesting to postulate why these species have such large, welldeveloped compound eyes. Other studies conducted in our laboratory suggest that for Nabicula subcoleoptrata and S. diadema, vision is critical to these species in another important activity, the avoidance of their own enemies (Freund and Olmstead 2000).…”

“…A survey of sensory modalities used in foraging (Freund and Olmstead 2000) indicated that terrestrial heteropterans employ olfaction and/or chemoreception and may also use vision and mechanoreception to locate prey. Unfortunately, relatively few published studies have included sensory manipulations of these predators (see Ambrose et al 1983Ambrose et al , 1986Awan et al 1989).…”

The evolution of vertebrate eye size across an environmental gradient: phenotype does not predict genotype in a Trinidadian killifish

“…). Despite the known importance of visual capabilities in the face of predation (Freund and Olmstead ; Kelley and Magurran ; Moller and Erritzoe ; Smolka et al. ; Hettyey et al.…”

“…Conversely, work has also shown that predators target heavily pigmented eyes and may therefore select for the evolution of a smaller eye (Zaret and Kerfoot 1975;Lonnstedt et al 2013). Despite the known importance of visual capabilities in the face of predation (Freund and Olmstead 2000;Kelley and Magurran 2003;Moller and Erritzoe 2010;Smolka et al 2011;Hettyey et al 2012), and other visually driven behaviors that are both directly and indirectly related to fitness (Dobberfuhl et al 2005; Thomas et al 2006;Hall 2008;Liu et al 2012), the extent to which predators exert selection and drive the evolution of eye size is unclear.…”

Odour-mediated sexual attraction in nabids (Heteroptera: Nabidae)

“…Sound measurements revealed no evidence that nabids use acoustic signals (Leston, 1957), and the extent to which they use visual cues to find mates is unknown (Freund & Olmstead, 2000;Roth & Remane, 2003). A role for chemical cues in sexual attraction has been suggested for nabids (Harris, 1928;Söcknick, 1974;Carayon, 1977;Pericart, 1987;Hartwig, 1990;Roth & Remane, 2003), but the evidence so far concerns the existence of male pheromones in the nabid Prostemma guttula (Kott, 2000) only (see Aldrich, 1988Aldrich, , 1995.…”
