“…Limited field data indicate that males aggregate on individual host plants and defend individual leaves as mating territories [Shelly & Kaneshiro, 1991; see Stark (1995) for a possible habitat‐related difference in mating behavior]. While perching on leaf undersides, males engage in vigorous wing‐fanning, an activity that both produces an audible buzz and disperses the sex pheromone (Roan et al., 1954; Schultz & Boush, 1971; Kobayashi et al., 1978). Upon detecting a female in his territory, the male immediately ceases wing‐fanning and jumps on the female.…”

Males of the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), are strongly attracted to, and feed voraciously on, methyl eugenol (ME) and use metabolites of this chemical to synthesize their sex pheromone. Previously, Wong et al. (1989) proposed that B. dorsalis males were attracted to ME even before attaining sexual maturity. However, their interpretation is possibly confounded by the fact that, in monitoring age‐related mating readiness, males were presented with equal‐aged females. As a result, if females mature more slowly than males, the age of male sexual maturation may have been overestimated, which may have accounted for the discrepancy observed between male age of ME responsiveness and mating activity. Here, we re‐examined the relationship between male age and mating readiness by comparing male mating activity when presented with same‐aged females vs. sexually mature females. In addition, we measured the age‐dependent response of B. dorsalis males to ME by recording (i) capture in ME‐baited traps, and (ii) feeding duration on ME‐containing paper discs. Our data support the conclusion of Wong et al. (1989) that B. dorsalis males show attraction to, and feed on, ME before attaining sexual maturity, but suggest that a marked difference in ME response and mating activity exists over a shorter age interval than indicated by Wong et al. (1989). Early attraction to, but not ingestion of, ME was related to accelerated sexual maturation. Unexpectedly, ingestion of ME by sexually immature males did not boost their mating success in trials conducted 10 days after feeding on the lure.

“…N-(3-methylbutyl)acetamide, has been found in the venom of Polistinae (Dani et al, 2000;Bruschini et al, 2006b;Bruschini et al, 2006c) and of Vespinae (Aldiss, 1983;Landolt et al, 1995). Although behavioural experiments have demonstrated its role as alarm substance in Vespinae (Aldiss, 1983;Landolt and Heath, 1987;Heath and Landolt, 1988) and in the cockroach Therea petiveriana (Farine et al, 2002), the same compound has also been reported in the male rectal gland secretion as a sexual attractant in fruit flies (Fletcher, 1969;Schultz and Bousch, 1971;Kobayashi et al, 1978;Bellas and Fletcher, 1979).…”

SUMMARYFoundresses and workers of Polistes paper wasps show slight morphological and physiological differences. However, after the emergence of the workers, the castes can be readily discriminated by their behaviour: the dominant foundress is the principal egg-layer, whereas workers perform different tasks linked to colony development. Previous studies have demonstrated in this genus that defence of the colony by the workers is more effectively carried out by a collective response elicited by venom volatiles used as alarm pheromones. In the present study, gas chromatography-mass spectrometry analyses of the venom volatiles of foundresses and workers of Polistes dominulus (Christ) show predominantly quantitative differences. Spiroacetals, mainly (E,E)-2,8-dimethyl-1,7-dioxaspiro[5.5]undecane, are significantly higher in the venom volatiles fraction of workers, whereas the amount of N-(3-methylbutyl)acetamide is almost double in foundresses. On the basis of the chemical results, behavioural assays were performed on fifteen field colonies to test the alarm response of the resident wasps to venom extracts from foundresses and workers. Our behavioural results suggest that worker venom has a stronger alarm effect on the colonies than that of the foundresses, which seems unable to elicit the complete alarm response ending with a final attack and sting. The venom volatiles of P. dominulus workers serve mainly to alarm the colony whilst those of foundresses may also be linked to additional functions related to conspecific interactions.

“…In integrated pest management, insect behavioural regulation has been recommended as an effective strategy for pest control (Ando, 2006;Bhattacharyya, 2017). The courtship and mating behaviours of B. dorsalis have been described in several early studies (Schultz & Boush, 1971;Kobayashi et al, 1978;Arakaki et al, 1984;Shelly & Kaneshiro, 1991;Shelly & Dewire, 1994;Shelly, 2001). In B. dorsalis, mate recognition and mating are displayed in a stereotypic sequence of behaviours.…”

Allyl‐2,6‐dimethoxyphenol, a female‐biased compound, is robustly attractive to conspecific males of Bactrocera dorsalis at close range

Insect cuticular hydrocarbons (CHCs) play important roles in mate recognition and chemical communication. To explore the cues regulating courtship and mating behaviour in the oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), CHCs were extracted from mature virgin female and male oriental fruit flies using n‐hexane. Nine compounds – i.e., 4‐allyl‐2,6‐dimethoxyphenol (designated ‘compound 3’) and eight ester compounds – had significantly greater abundance in female samples than in males. Of these nine compounds, six (1, 2, 4, 5, 6, and 8) elicited electrophysiological responses from the antennae of male flies. Compound 3 did not elicit a detectable male antennal response, but in Y‐tube olfactometer bioassays, it exhibited robust attractiveness to conspecific males at close range. We speculate that compound 3 is a close‐range sex pheromone in B. dorsalis. A mating competition experiment revealed that compound 3 significantly increased the competitiveness of males, which implied that compound 3 might be used in control programs of B. dorsalis.
