“…Ginzel and Hanks (2005) hypothesized that cerambycine mate location and recognition results from three sequential behaviors: (1) both sexes are independently attracted to larval hosts by plant volatiles; (2) males attract females at short-range with pheromones; and (3) males recognize females by contact pheromones. In our study, female H. betulinus were not attracted to host-plant volatiles alone, indicating that mate location involves only stages 2 and 3, consistent with previous observations of the mating behavior of this species (Fonseca and Zarbin, 2009).…”

Male-Produced Sex Pheromone of the Cerambycid Beetle Hedypathes betulinus: Chemical Identification and Biological Activity

We identified, synthesized, determined the diel periodicity of release, and tested the bioactivity of components of the male-produced sex pheromone of Hedypathes betulinus (Coleoptera: Cerambycidae: Lamiinae). Gas chromatographic-mass spectrometric analysis of headspace volatiles from adult beetles showed three male-specific compounds, which were identified as (E)-6,10-dimethyl-5,9-undecadien-2-yl acetate (major component), (E)-6,10-dimethyl-5,9-undecadien-2-one (geranylacetone), and (E)-6,10-dimethyl-5,9-undecadien-2-ol. Release of these chemicals was dependent on time of the photoperiod and presence of the host plant. Pheromone release took place primarily during the photophase, with maximum release occurring between 4 and 6 hr after the onset of photophase. The amount of pheromone released by males was much greater when they were in the presence of their host plant than when they were not. In Y-tube olfactometer tests, a ternary mixture of the compounds was attractive to female beetles, although the individual compounds were not attractive by themselves. Addition of volatiles from the host plant greatly increased the attractiveness of the ternary pheromone mixture and of the major pheromone component alone.

“…These strategies often involve sensing of water-borne sound (Schwartz et al 2004), visual signals (Díaz and Thiel 2004), chemical cues (Ginzel and Hanks 2005), or a combination of two or more of the above (Uetz et al 2009). Cues might originate either from members of the opposite sex (Díaz and Thiel 2004) or from the refuges (i.e., host species in symbiotic organisms) harboring them (Ginzel and Hanks 2005;Ambrosio and Baeza 2016), and the efficiency with which individuals transmit and/or perceive cues depends on environmental conditions. In shallow marine environments, for instance, sound and light propagation can be erratic (e.g., due to sudden shifts in water turbidity and/or density; Astoreca et al 2006), in turn impacting the ability to perceive the direction and/or distance of the signal's origin (Meager et al 2005).…”

Population distribution, host-switching, and chemical sensing in the symbiotic shrimp Lysmata pederseni: implications for its mating system in a changing reef seascape

et al. 2016

Lysmata pederseni, a protandric simultaneously hermaphroditic shrimp that inhabits the tube sponge Callyspongia vaginalis, is monogamous in the central and southeastern Caribbean Sea. We tested the null hypothesis of monogamy in a northern Caribbean population. In the Florida Keys, shrimps did not inhabit host individuals in pairs with a frequency greater than expected by chance alone. Hermaphrodites inhabited sponges solitarily and often brooded embryos. Hermaphrodites do not store sperm and need to be inseminated shortly after molting to fertilize a new batch of eggs. Thus, males and/or other hermaphrodites are likely switching among host individuals in search of sexual partners. Field experiments demonstrated low shrimp host fidelity. Host residence time was *2 times shorter for males than for hermaphrodites. We inferred a polygynandrous mating system from L. pederseni from the Florida Keys, with male-role and young hermaphrodites often moving among sponges in search of older, more sedentary, female-role hermaphrodites. We expected shrimps to use water-borne chemical cues originating from conspecifics or sponges to locate sexual partners. Experiments demonstrated that shrimps were attracted to waterborne cues originating from sponges but not conspecifics. We have described the mating system of a reef-associated shrimp in a fast-pace shifting seascape increasingly dominated by sponges and vanishing stony corals. In the central and southeastern Caribbean Sea, with greater coral cover and lower sponge abundance than in the Florida Keys, the same species is monogamous. Whether or not similar shifts in the social organization of other coral reef-dwelling marine organisms are occurring due to contemporary changes in seascapes is a relevant topic that deserves further attention.

“…The elongate antennae of other cerambycid species, the "longhorned beetles" for which the family is named, apparently are adaptive because males recognize females by antennal contact chemoreception, and the probability of finding a mate is determined by area search rate (Hanks et al 1996a;Hanks 1999). Elongate antennae may not be of selective advantage; however, if males produce attractants that draw females into their proximity (for a review, see Ginzel and Hanks 2005). Thus, antennal length also may provide a morphological indication that volatile pheromones play a role in mate location.…”

Males of five species of three tribes in the longhorned beetle subfamily Cerambycinae produce volatile pheromones that share a structural motif (hydroxyl or carbonyl groups at carbons two and three in straight-chains of six, eight, or ten carbons). Pheromone gland pores are present on the prothoraces of males, but are absent in females, suggesting that male-specific gland pores could provide a convenient morphological indication that a species uses volatile pheromones. In this article, we assess the taxonomic distribution of gland pores within the Cerambycinae by examining males and females of 65 species in 24 tribes using scanning electron microscopy. Gland pores were present in males and absent in females of 49 species, but absent in both sexes of the remaining 16 species. Pores were confined to indentations in the cuticle. Among the species that had male-specific gland pores were four species already known to produce volatile compounds consistent with the structural motif. These findings support the initial assumption that gland pores are associated with the production of pheromones by males. There were apparently no taxonomic patterns in the presence of gland pores. These findings suggest that volatile pheromones play an important role in reproduction for many species of the Cerambycinae, and that the trait is evolutionarily labile.
