“…The largest EPG responses of B. scutellata to cue lure and raspberry ketone and their smallest EAG responses to these compounds suggest that cue lure and raspberry ketone are detected by the maxillary palps, not by the antennae, in this species. It has been reported that cue lure and raspberry ketone are behaviorally attractive to the males of B. scutellata (Al Baki et al, ; K. Kim, Kim, Kwon, & Kim, ), and our study shows that the strong behavioral attraction of male B. scutellata to cue lure and raspberry ketone is well correlated to the electrophysiological activities of these compounds on the olfactory sensory neurons in the maxillary palps. This is a strong indication that the attraction of male B. scutellata to cue lure and raspberry ketone is achieved through the detection of these compounds by the olfactory sensory neurons present in the maxillary palps.…”

Here, we report that the olfactory attraction of the striped fruit fly, Bactrocera scutellata (Hendel; Diptera: Tephritidae), a serious pest of pumpkin and other cucurbitaceae plants, to cue lure and raspberry ketone is mediated by the maxillary palps. The antennae, bearing three morphological types (basiconic, trichoid, and coeloconic) of olfactory sensilla, in male and female B. scutellata exhibited significant electroantennogram (EAG) responses to a plant volatile compound, 3-octanone, and methyl eugenol, whereas cue lure, raspberry ketone, and zingerone that are known to attract several other species of Bactrocera fruit flies elicited no significant EAG responses from both sexes. In contrast, maxillary palps, housing one morphological type of basiconic sensilla, displayed the largest electropalpogram (EPG) responses to cue lure followed by raspberry ketone among the five compounds tested in male and female B. scutellata, with only minor EPG responses to 3-octanone, which indicates that the maxillary palps are responsible for detecting cue lure and raspberry ketone in this species. In field trapping experiments, significant number of male B. scutellata were captured in the traps baited with cue lure or raspberry ketone, in which the attractiveness of cue lure was significantly higher than that of raspberry ketone. Methyl eugenol and zingerone were not behaviorally attractive to B. scutellata although they elicited significant EPG responses.Our study indicates that the behavioral attraction of B.Arch.

“…Its larvae feed pumpkin flowers within stamen which prevents their exposure to chemical insecticides [27]. Although a mixture treatment of male lure (raspberry ketone or cuelure) with insecticides has been effective for controlling its population [28], SIT has been regarded as one of the most effective control tactics against this insect pest [29]. An obstacle for SIT is the tedious sorting out of females to be removed.…”

Sterile insect release technique (SIT) is effective for eradicating quarantine insects including various tephritid fruit flies. When SIT is used for fruit flies, it is challenging to remove females from sterile males due to oviposition-associated piercing damage. This study developed a sex transition technique by feeding double-stranded RNA (dsRNA) specific to a sex-determining gene, Transformer-2 (Zs-Tra2) of the striped fruit fly, Zeugodacus scutellata. Zs-Tra2 is homologous to other fruit fly orthologs. It is highly expressed in female adults. RNA interference (RNAi) of Zs-Tra2 by injecting or feeding its specific dsRNA to larvae significantly increased male ratio. Recombinant Escherichia coli cells expressing dsRNA specific to Zs-Tra2 were prepared and used to feed larvae to suppress Zs-Tra2 gene expression levels. When these recombinant bacteria were fed to larvae during the entire feeding stage, the test population was significantly male-biased. Some females treated with such recombinant E. coli exhibited mosaic morphological characters such as the presence of male-specific abdominal setae in females. This study proposes a novel technique by feeding dsRNA specific to Transformer-2 to reduce female production during mass-rearing of tephritid males for SIT.

“…Alarm pheromone components were formulated using wax for fence treatment by pasting. The wax formulation modified the methods used in other lure formulations developed using moth sex pheromone and fly lure, where their efficacy was confirmed in field conditions [28,37]. The bioactivity of the wax formulation of the alarm pheromone lasted for at least four weeks in greenhouse conditions.…”

“…The alarm pheromone (a mixture of decyl acetate and dodecyl acetate in 1.5:1, g/g) was formulated in wax by the method of Kim et al [28]. Briefly, paraffin wax (Merck, Rahway, NJ, USA) was dissolved and mixed with an emulsifier (Almax 3600, Illshinwells, Seoul, Korea), αtocopherol (96%), and jojoba oil (see Fig 5A).…”

Since the first report in 1993 in Korea, the western flower thrips, Frankliniella occidentalis, has been found in various crops throughout the country. Although more than 20 different chemical insecticides are registered to control this insect pest, its outbreaks seriously damage crop yields, especially in greenhouses. This study developed a non-chemical technique to control F. occidentalis infesting hot peppers cultivated in greenhouses. The method was based on behavioral control using an alarm pheromone (“Push”) to prevent the entry of the thrips into greenhouses and an aggregation pheromone (“Pull”) for mass trapping inside the greenhouses. The greenhouse fences were treated with a wax formulation of the alarm pheromone and a yellow CAN trap covered with sticky material containing the aggregation pheromone was constructed and deployed inside the greenhouses. Field assay demonstrated the efficacy of the push-pull tactics by reducing thrips density in flowers of the hot peppers as well as in the monitoring traps. Especially, the enhanced mass trapping to the CAN trap compared to the conventional yellow sticky trap led to significant reduction in the thrips population. This novel push-pull technique would be applicable to effectively control F. occidentalis in field conditions.
