“…In this study, our results showed that the odor of Solanaceae crops is a key cue affecting their ability to attract gravid Z. tau females. Previous studies have shown that the color and odor of the host are two important physicochemical characteristics that influence the attraction of fruit flies [55,63,65]. The olfaction of fruit flies is an important contributor to host location in complex environments and over long ranges [63], while fruit flies' vision was found to be more significant with regard to their host preferences over short ranges [63].…”

“…This is consistent with previous research on several polyphagous fruit flies (Diptera: Tephritidae), such as B. zonata [51,52], Z. cucurbitae [52,53], A. obliqua [54], Neoceratitis cyanescens [55], B. oleae [56], B. tryoni [57,58], B. dorsalis [23,40,59,60], and B. latifrons [61,62]; these studies found that the ability to attract fruit flies differed between species and cultivars of host plants. Polyphagous fruit flies with higher olfactory plasticity are able to recognize and use more hosts and choose their preferred host plants more than [63]. The previous studies indicated that hosts with greater attraction were advantageous to the offspring performance of fruit flies [51,53,[56][57][58]60].…”

Zeugodacus tau (Walker) (Diptera: Tephritidae) is a pest seriously harmful to Solanaceae crops and was found to oviposit on the pepino melon Solanum muricatum (Aiton). To date, the differences in the ability of the fruits of S. muricatum and other Solanaceae crops to attract gravid Z. tau females have seldom been reported. Oviposition and trapping bioassays were performed to clarify whether such differences existed. A combination of GC-MS and the Y-tube olfactometer system was used to identify and determine the compounds inducing behavioral responses in gravid Z. tau females to the volatile odors of S. muricatum. The results show that S. muricatum odors play a role in attracting gravid Z. tau females. The odors of Solanaceae crops influence their ability to attract these organisms. The nine compounds from the volatiles of S. muricatum induce tendency or repellency responses in gravid Z. tau females. Hexyl acetate, butyl acetate, amyl actate, and isoamyl acetate caused tendency behavior in gravid Z. tau females, while hexyl hexanoate, butyl isovalerate, butyl valerate, and isoamyl hexanoate caused repellency behavior. Heptyl acetate caused repellency behavior in gravid Z. tau females at higher concentrations (5 mg/mL) but caused tendency behavior at a low concentration (0.5 mg/mL). These results suggest that vigilance against the harm caused by Z. tau is required during the cultivation of S. muricatum. The nine compounds of the volatile odors of S. muricatum could help to develop attractants and repellents for gravid Z. tau females. These results are beneficial for preventing Z. tau females from harming S. muricatum, developing attractants and repellents for Z. tau females, and establishing a system of ecological control for Z. tau females.

“…Through scanning electron microscopy of the compound eye, retinal potentials, and other studies, many species’s light-sensitive peaks and the basic structure of the insect compound eye have been elucidated [ 50 , 51 ]. Molecular biology-based investigations of visual genes in insects hold promise for unraveling insect phototactic behavior [ 52 , 53 ].…”

The phototactic behavior of insects is commonly used to manage pest populations in practical production. However, this elusive behavior is not yet fully understood. Investigating whether the opsin genes play a crucial role in phototaxis is an intriguing topic. Vespinae (Hymenoptera: Vespidae) are a common group of social wasps that are closely associated with human activities. Efficiently controlling wasp populations while maintaining ecological balance is a pressing global challenge that still has to be resolved. This research aims to explore the phototactic behavior and key opsin genes associated with Vespinae. We found significant differences in the photophilic rates of Vespula germanica and Vespa analis under 14 different light conditions, indicating that their phototactic behavior is rhythmic. The results also showed that the two species exhibited varying photophilic rates under different wavelengths of light, suggesting that light wavelength significantly affects their phototactic behavior. Additionally, the opsin genes of the most aggressive hornet, Vespa basalis, have been sequenced. There are only two opsin genes, one for UV light and the other for blue light, and Vespa basalis lacks long-wavelength visual proteins. However, they exhibit peak phototaxis for long-wavelength light and instead have the lowest phototaxis for UV light. This suggests that the visual protein genes have a complex regulatory mechanism for phototactic behavior in Vespinae. Additionally, visual protein sequences have a high degree of homology among Hymenoptera. Despite the hypotheses put forward by some scholars regarding phototaxis, a clear and complete explanation of insect phototaxis is still lacking to date. Our findings provide a strong theoretical basis for further investigation of visual expression patterns and phototactic mechanisms in Vespinae.

“…For instance, three notable comparative genomics investigations focused on the fall armyworm Spodoptera frugiperda provided valuable information on the genetic adaptations related to polyphagia and insecticide resistance, which greatly enhanced our understanding of its rapid global dispersal, invasion, and pest management in China around 2019 ( Xiao et al, 2020 ; Zhang et al, 2020 ; Gui et al, 2022 ). Additionally, a comparative genomics study between a generalist and a specialist Bactrocera fruit fly elucidated the role of vision and olfaction evolution in feeding habit divergence, potentially inspiring new pest control strategies ( Wang et al, 2022 ). Moreover, genomic analyses of the western flower thrip Frankliniella occidentalis answered that why this species has the skills to find, colonize, and survive on various crops ( Rotenberg et al, 2020 ).…”

Ephestia elutella is a major pest responsible for significant damage to stored tobacco over many years. Here, we conduct a comparative genomic analysis on this pest, aiming to explore the genetic bases of environmental adaptation of this species. We find gene families associated with nutrient metabolism, detoxification, antioxidant defense and gustatory receptors are expanded in the E. elutella genome. Detailed phylogenetic analysis of P450 genes further reveals obvious duplications in the CYP3 clan in E. elutella compared to the closely related species, the Indianmeal moth Plodia interpunctella. We also identify 229 rapidly evolving genes and 207 positively selected genes in E. elutella, respectively, and highlight two positively selected heat shock protein 40 (Hsp40) genes. In addition, we find a number of species-specific genes related to diverse biological processes, such as mitochondria biology and development. These findings advance our understanding of the mechanisms underlying processes of environmental adaptation on E. elutella and will enable the development of novel pest management strategies.
