In the insect phylum, the relationships between individuals and their environment are often modulated by chemical communication. Odorant binding proteins (OBPs) are widely and robustly expressed in insect olfactory organs and play a key role in chemosensing and transporting hydrophobic odorants across the sensillum lymph to the olfactory receptor neuron. In this study, a novel OBP gene (AlinOBP1) in the lucerne plant bug, Adelphocoris lineolatus was identified, cloned and expressed. Real-time PCR results indicated that the expression level of AlinOBP1 gene differed in each developmental stage (from first instar to adult) and was predominantly expressed in the antennae of adults. The expression level of AlinOBP1 was 1.91 times higher in male antennae than in female antennae. The binding properties of AlinOBP1 with 114 odorants were measured using a fluorescence probe, N-phenyl-1-naphthylamine (1-NPN), with fluorescence competitive binding. The results revealed that AlinOBP1 exhibits high binding abilities with two major putative pheromone components, ethyl butyrate and trans-2-hexenyl butyrate. In addition, it was observed that six volatiles released from cotton, octanal, nonanal, decanal, 2-ethyl-1-hexanol, b-caryophyllene and b-ionone also bind to AlinOBP1. Immunocytochemistry analysis showed that AlinOBP1 was expressed in the sensillum lymph of sensilla trichodica and sensilla basiconca. Our results demonstrate that AlinOBP1 may function as a carrier in the chemoperception of the lucerne plant bug. C 2011 Wiley Periodicals, Inc.

“…A 0.5-l glass chamber was connected to one of the four olfactometer arms and was used to dispose of the odor source. Three stimuli were tested on both H. axyridis males and females: (1) the four arms of the olfactometer were connected to pure air sources, the glass chamber remained empty; (2) 20 unwinged adult aphids, Myzus persicae Sultzer, were rapidly crushed inside of the glass chamber by using a small glass pestle left inside the chamber [as a natural source of EβF: according to previous studies, the volatiles released by crushed M. persicae consist exclusively of EβF (Edwards et al 1973;Francis et al 2005)]; (3) a 0.5-cm 2 piece of filter paper was impregnated with 10 μl of (−)-β-caryophyllene and placed inside the glass chamber. The glass chamber was randomly connected to one of the four arms of the olfactometer.…”

Electrophysiological and Behavioral Responses of the Multicolored Asian Lady Beetle, Harmonia axyridis Pallas, to Sesquiterpene Semiochemicals

The role of two volatile sesquiterpenes, (E)-β-farnesene and (−)-β-caryophyllene, in the chemical ecology of the multicolored Asian lady beetle, Harmonia axyridis Pallas, was investigated by using both electrophysiological and behavioral techniques. (E)-β-Farnesene is the major component of the alarm pheromone of most aphid species, which are preyed on by H. axyridis. (−)-β-Caryophyllene was previously isolated from the headspace volatiles above overwintering and aggregated H. axyridis females. These sesquiterpenes elicited significant electroantennogram (EAG) activity from both H. axyridis male and female antennae. In a four-arm olfactometer, male and female H. axyridis were highly attracted toward (E)-β-farnesene, whereas only males were attracted to (−)-β-caryophyllene. In a bioassay technique that used a passively ventilated plastic box, both male and female H. axyridis aggregated in the (−)-β-caryophyllene-treated side of the box. These results support the potential usefulness of (E)-β-farnesene and (−)-β-caryophyllene in push-pull strategies that use H. axyridis as a biological control agent in aphid-infested sites or to control this new urban pest in residential structures.

“…Typical responses range from the cessation of feeding and removal of the stylet from host plant tissues to walking, jumping, or falling away from the source of emission (Edwards et al, 1973;Wientjens et al, 1973;Phelan et al, 1976;Nault, 1977a, b, 1978;Roitberg and Myers, 1978;Wohlers, 1980;Clegg and Barlow, 1982;Chau and Mackauer, 1997;Losey and Denno, 1998;Shah et al, 1999;Braendle and Weisser, 2001). In the sugar-cane woolly aphid, Ceratovacuna lanigera Zehntner (Homoptera, Pemphigidae), the alarm pheromone reportedly elicited aggressive behavior from conspecifics (Arakaki, 1989).…”

In this chapter we discuss our current understanding of chemical alarm signaling in a variety of animal groups (including social and pre-social insects, marine invertebrates, fish, and mammals) and in plants. We also briefly discuss the exploitation of alarm pheromones as foraging cues for natural enemies. We conclude with a brief discussion of the potential exploitation of alarm signaling to achieve the applied goal of managing pest species.
