“…Similar results were reported by Umeya et al (1973) and Wong et al (1989) in B. dorsalis males whereby their attractancy to ME was shown to be strongly correlated with the onset of sexual maturity.

Bactrocera carambolae Drew & Hancock and B. papayae Drew & Hancock (Diptera: Tephritidae), two closely related sibling species in the B. dorsalis (Hendel) complex were shown to have different rates of sexual maturity. The response of B. carambolae males to methyl eugenol was observed to begin 10 days after emergence and increased with age. The attractancy peaked at 28 days after emergence and above. The males were also found to require a higher dosage of methyl eugenol (1 mg) for optimal response. These results are in contrast with those of B. papayae reported previously. The response to methyl eugenol was also observed to correspond with the age when first mating was performed.After eclosion, both sexes of B. carambolae mated approximately 2 weeks later and showed significantly lower matings/individual when compared with B. papayae in a 60-day observation period. Both sexes of B. papayae and males of B. carambolae were able to remate on the next day. However, B. carambolae females required a minimum refractory period of 8 days in order to be sexually receptive again.During the 60-day period, the mating propensity in B. papayae (100% success) was higher than B. carambolae (71-87% success) (P < 0.05). This observation was substantiated by a higher intraspecific mating success of B. papayae as compared to B. carambolae in a field cage (P < 0.001).

“…However, Fitt (1981b) reported that attraction of male B. opilae, (a species very closely related to B. dorsalis) to ME commenced only after some days after emergence. This observation was reported by some other researchers as well (Umeya et al 1973;Ibrahim and Hashim 1980). BriezeStegeman et al (1978) reported that responsiveness of male B. opilae to ME was inversely related to the daily cycle of mating behaviour.…”

“…Umeya et al (1973) observed that male fruit flies were not attracted to ME until the ninth day, suggesting that sexual maturity may play a prominent role. Similarly, Ibrahim and Hashim (1980) reported low attraction of 4 day old male oriental fruit flies to ME.…”

The parapheromone, methyl eugenol (ME) (3, 4 dimethoxyalyl benzene), occurring in a variety of plant species, is the most effective known lure attracting the male oriental fruit fly, Bactrocera dorsalis (Hendel). Bioassays were carried out in a wind tunnel under laboratory conditions, to evaluate behavioural responses of male flies to seven concentrations of ME, diurnal pattern of male responsiveness and age of responsiveness to methyl eugenol and the factors influencing the responsiveness of males to ME. Attraction of male flies to ME was assessed by monitoring three behavioural parameters namely the number of flies performing upwind zigzagging anemotactic flights over at least 50cm to the ME source, total number of flies landing on the source and the total number of flies moved into the upwind section of the wind tunnel after 20 minutes. The responsiveness of males to ME increased with the increase of the concentration, 0.0001µl eliciting the lowest and 5.0µl producing the highest attraction in males. All the males which were attracted exhibited a feeding response and no other behavioural response was observed. Male responsiveness to ME was not uniform throughout the day. The responses were highest during the morning (82.6%), declined to a lower level in the afternoon (41.8%) and then dropped markedly at the 'dusk' period (11.4%). This decline in response to ME suggested an inverse relationship to the time of peak mating activity in the male. Male responsiveness to ME was found to be age-dependent. The response to the attractant increased with the age of the flies indicating a relationship between responses to ME and sexual maturity of the flies. No significant responses were evident when males were 1, 3 and 5 days old. Males were strongly attracted to ME by the time they were 10d-old and the highest attraction was observed in 15d-old males. Attraction to ME was still considerably high even when they were 25 and 30d-old.

“…Thus, a small proportion of immature males may respond to the lures, but the percentage of responders increases most rapidly as males attain sexual maturity and then remains high for a long period thereafter. This pattern has now been described for both ME-responding species (B. dorsalis, Umeya et al, 1973;Ibrahim and Hashim, 1980;Tan et al, 1987;Wong et al, 1989;Shelly et al, 2008;B. opiliae, Fitt, 1981a;B.…”

Effects of methyl eugenol and raspberry ketone/cue lure on the sexual behavior of Bactrocera species (Diptera: Tephritidae)

Bactrocera is a speciose genus of tephritid fruit fly that includes several important pests of fruits and vegetables. Detection and control of these pestiferous species rely heavily upon male attractants or lures, with different Bactrocera species responding to either methyl eugenol (ME) or raspberry ketone (RK; or its man-made analogue cue lure, CL). Despite their usage worldwide, the function of ME and RK/CL in the natural history of Bactrocera flies is poorly known. The purpose of this review is to summarize research on the potential role of ME and RK/CL-as pheromone precursors or components-in the sexual communication of Bactrocera species. The topics covered include i) male feeding behavior on ME or RK/CL, ii) the fate of ingested lures, iii) female and male attraction to lure-fed males, and iv) mating success of lure-fed males. Data are available for only a few species, but they provide solid evidence for a role of male lures in mating behavior. For several ME-responding species, research has shown that i) ME metabolites are incorporated and emitted along with endogenously produced components of the male sex pheromone, ii) females show preferential attraction to pheromone containing these metabolites, and iii) males fed ME (or plants containing ME) enjoy increased mating success over non-fed males. Fewer studies have been conducted on RK/CL-responding species, and these reveal i) the lure is not broken down or metabolized but is sequestered (and presumably emitted) as RK, ii) females show preferential attraction to pheromone produced by males that fed upon RK/CL, and iii) RK/CL ingestion produces a significant, but short-lived (1 d), boost in male mating success. Potentially productive avenues of future research are discussed.
