“…The SEM results for the shape and structure of sensilla on the labial and maxillary palps of adult C. villosulum are basically the same as those reported for other long-horned beetles, such as Xylotrechus grayii (Chen et al, 2018) and Anoplophora glabripennis (Hall et al, 2019) but showed differences in terms of numbers and sizes. In this study, SB IV and SCa on the labial and maxillary palps of females were significantly more developed than those of males.…”

“…Labial palps (LP) and maxillary palps (MP) are the mouthparts of insects; these organs are usually associated with contact chemoreceptors and are equipped with sensilla that contain taste chemoreceptors (Hall, Graves, Myrick, Hoover, & Baker, 2019). They are responsible for a variety of stimuli, especially responses to information chemicals related to host searching, positioning, and food acceptance (Hu, Li, & Feng, 2020; Jefferis, 2005; Lu et al, 2011; Shi et al, 2021).…”

Related studies on long‐horned beetles showed that the main function of the labial and maxillary palps is to participate in host selection, mating, and oviposition (Hall et al, 2019; Yang, Ren, Wang, Xu, & Zong, 2017). The study of the shape and distribution of different sensilla will improve the knowledge on the efficiency and sensitivity of olfactory perception, which is closely related to the specific behaviors of insects (Ren, Wu, Shi, Zhang, & Luo, 2014).…”

This study used scanning electron microscopy (SEM) to observe the morphology and sensilla of the labial and maxillary palps of adult Callidiellum villosulum Fairmaire between sexes. Combining behavioral activities may provide an effective control target for this pest. In this study, the results showed that there were three segments on the labial palps and four segments on the maxillary palps. The length and width of each segment of the labial and maxillary palps were significantly larger in females than in males. Four types of sensilla were found on the labial and maxillary palps of both sexes of adult C. villosulum: sensilla basiconica (SB I, II, III, and IV), sensilla chaetica (SCh I and II), sensilla placodea (SP), and sensilla campaniformia (SCa). SB IV, SCa, and Sh II were significantly more developed on female labial and maxillary palps than on males', which may be related to their oviposition behavior. By contrast, SB I was more significantly developed on males than on females, which may be related to their mating selection. At the same time, for both sexes, the numbers of Sh I and Sh II on the maxillary palps were significantly higher on labial palps. Maxillary palps could be inferred to potentially play a more important role than the labial palps in the activities of adult C. villosulum. Results will help us further understand the host selection and egg‐laying behavior of adult C. villosulum. Such an understanding shall greatly promote the information‐based design of pest control methods.

“…Phytophagous insects locate and recognize host plants via multiple cues, such as odor (olfactory cues), color, size and shape (visual cues), and even auditory and gustatory signs [ 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ]. Many previous studies focused on olfactory cues in adult ALBs, and large quantities of volatile organic compounds have been identified from host and nonhost plants ( Table 1 ).…”

The Asian longhorn beetle (ALB), Anoplophora glabripennis Motschulsky, is a polyphagous xylophage with dozens of reported host tree species. However, the mechanisms by which individuals locate and recognize host plants are still unknown. We summarize the current knowledge of the host plant list, host kairomones, odorant-binding proteins (OBPs) and microbial symbionts of this beetle and their practical applications, and finally discuss the host localization and recognition mechanisms. A total of 209 species (or cultivars) were reported as ALB host plants, including 101 species of higher sensitivity; host kairomones were preferentially bound to ALB recombinant OBPs, including cis-3-hexen-1-ol, δ-3-carene, nonanal, linalool, and β-caryophyllene. In addition, microbial symbionts may help ALB degrade their host. Complementarity of tree species with different levels of resistance may reduce damage, but trapping effectiveness for adults was limited using a combination of host kairomones and sex pheromones in the field. Therefore, we discuss host location behavior from a new perspective and show that multiple cues are used by ALB to locate and recognize host plants. Further research into host resistance mechanisms and visual signal recognition, and the interaction of sex pheromone synthesis, symbiont microbiota, and host plants may help reveal the host recognition mechanisms of ALBs.

“…This confirms the suggestion made by Kent et al (1986) that the axon projections to the LPOGs originated from sensory neurons housed inside the pit and that the branches seen in the GNG were parts of other sensory neuron types. Interestingly, a short peg sensillum type responding to humidity was recently identified on the labial palp of the Asian longhorned beetle, Anoplophora glabripennis (Hall et al, 2019).…”

Lepidopteran species detect CO 2 via a specialized organ located on the peripheral segment of the labial palps, the labial palp pit organ (LPO). Based on tracing of LPO sensory neurons targeting one distinct antennal-lobe glomerulus, Kent and her colleagues described the projections originating from the LPO in the sphinx moth as "an accessory olfactory pathway in Lepidoptera" already in the 1980 ties. In spite of similar reports from studies of other lepidopteran species, however, it has been an unresolved issue whether additional termination areas of the labial nerve, such as the gnathal ganglion (GNG) and the ventral nerve cord, are actually output sites of LPO neurons. Since the previous studies have interpreted slightly differently about the projection pattern occurring from the classical mass staining, we performed selective mass staining from the inside of the pit and from the outer surface of the peripheral palp. The results demonstrated that the LPO sensory neurons project exclusively to the LPO glomerulus (LPOG), whereas the non-LPO sensory neurons target the GNG and the ventral nerve cord. Additional iontophoretic staining of individual LPO sensory neurons, performed from the LPO and the LPOG, showed three morphological neuron types: one bilateral targeting the LPOG in both antennal lobes, one unilateral targeting the ipsilateral LPOG only, and one contralateral targeting the LPOG in the other antennal lobe. Finally, to explore putative differences in the projection pattern of neurons housed by two previously reported sensillum types in the pit, i.e., hair-shaped sensilla located distally and club-shaped sensilla located proximally, we performed mass staining from two different levels of the peripheral palp. We found a projection pattern implying stronger innervation of the ipsi-than the contralateral LPOG in both staining experiments.
