“…However, wild males (that did not feed on ME) were shown to produce large quantities of β-caryophyllene, α-humulene, and alloaromadendrene, along with ZCF and DMC in trace amounts [10]. The compound β-caryophyllene has also been demonstrated to be a more specific and potent male lure than ME for B. correcta [11,22]. Currently, however, the chemical composition of rectal pheromone glands of B. correcta females has not been investigated, and the age-related chemical composition of both sexes is unknown.…”

The guava fruit fly, Bactrocera correcta, is one of the major pests affecting mango (Mangifera indica) and guava (Psidium guajava) production in China. The compound β-caryophyllene was identified from the rectal gland extracts of wild B. correcta males and was demonstrated to be a more specific and potent male lure than methyl eugenol (ME) for B. correcta. In order to find potential additional pheromone attractants for the monitoring and mass-trapping of this fruit fly, a series of chemical and behavioral assays were conducted in this study. Ten compounds were identified from the rectal glands of virgin B. correcta females. These compounds consisted of five major compounds (i.e., ethyl dodecanoate, ethyl tetradecanoate, ethyl (E)-9-hexadecenoate, ethyl hexadecanoate, and ethyl (Z)-9-octadecenoate) in high quantities, and other compounds (i.e., octanal, N-(3-methylbutyl) acetamide, (Z)-9-tricosene, ethyl octadecanoate, and ethyl eicosanoate) in trace amounts, while virtually no compounds were found in male rectal glands. The bioassays indicate that female rectal gland extracts are attractive to virgin females and males. Furthermore, a cyclical production of the five major compounds was found, recurring at roughly 10-d intervals with peaks in 10–13-, 25-, and 35-d-old females. Collectively, these results will contribute to the understanding of pheromone communication in B. correcta and may provide important information for improving existing monitoring and control methods for this pest.

“…In another field trap test conducted in Thailand, using β-caryophyllene resulted in the capture of seven times more B. correcta males than ME-baited traps [44]. While ME attracted only mature males, β-caryophyllene could also attract immature males, suggesting an effective lure candidate [44,45]. The attractiveness of female B. correcta and B. dorsalis to β-caryophyllene at high concentrations has also been reported using a Y-tube olfactometer [46].…”

Dacini fruit flies mainly contain two genera, Bactrocera and Zeugodacus, and include many important pests of fruits and vegetables. Their life cycle is affected by various environmental cues. Among them, multiple characteristic semiochemicals have remarkable effects on their reproductive and host-finding behaviors. Notably, floral fragrances released from so-called fruit fly orchids strongly attract males of several Dacini fruit fly species. Focusing on the strong attraction of male flies to particular chemicals, natural and synthetic lures have been used for pest management. Thus, the perception of semiochemicals is important to understand environmental adaptation in Dacini fruit flies. Since next-generation sequencers are available, a large number of chemosensory-related genes have been identified in Dacini fruit flies, as well as other insects. Furthermore, recent studies have succeeded in the functional analyses of olfactory receptors in response to semiochemicals. Thus, characterization of molecular components required for chemoreception is under way. However, the mechanisms underlying chemoreception remain largely unknown. This paper reviews recent findings on peripheral mechanisms in the perception of odors in Dacini fruit flies, describing related studies in other dipteran species, mainly the model insect Drosophilamelanogaster. Based on the review, important themes for future research have also been discussed.

“…These results correspond with previous studies on both laboratory and wild strains of B. dorsalis (Wong et al, 1989; Shelly et al, 2008; Shelly, 2020). However, Bactrocera correcta Bezzi males respond to ME only when sexually mature (Kamiji et al, 2018). The male response to ME at pre‐maturation age has implications for the success of MAT application.…”

The peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae), is a pest of economic importance, endemic to South and South‐East Asia. It is highly invasive and due to its quarantine pest status, it interferes with horticultural trade. Males of many Bactrocera species are strongly attracted to methyl eugenol (ME) [1,2‐dimethoxy‐4‐(2‐propenyl) benzene], a phenylpropanoid compound naturally occurring in many plant species. Feeding on ME is also reported to enhance male mating success in several Bactrocera species. Such an effect can increase the effectiveness of the sterile insect technique (SIT). The current study was designed to identify the sexual maturity age of males of B. zonata, the relation between male age and attraction to ME, and the effect of ME on male mating success. The results showed that males initiated their mating at 8 days of age and attained the highest mating success at 16 days of age. The percentage of immature males responding to ME increased with age and the maximum response was observed during the age of sexual maturity. Methyl eugenol treatment at sexual maturity significantly enhanced male mating success over untreated males. The males treated with ME at a sexually immature age (5 days old) achieved significantly higher mating success after reaching sexual maturity. These findings suggested that B. zonata males can be treated with ME at the age of 5 days in sterile‐male ‘holding and release’ facilities and thereafter released in the field, where they are expected to achieve higher mating success after attaining sexual maturity. The results are discussed as a valid approach for enhancing the effectiveness of SIT application against B. zonata.
