Previously, α-pinene and limonene were identi ed in the volatiles of L. gmelinii and S. oblata(Qiang et al 2019, Ju et al 2021, consistent with our results. The volatiles of S. oblata leaves were extracted by hydrodistillation, and found to contain α-pinene, which varied greatly with different seasons(Hui et al 2008), but the content and proportion of compounds were discrepant with those in our experiment.…”

The repellent tree species or their volatiles of Hyphantria cunea can be used for "push and pull strategy" integrated control to improve the capture to H. cunea in the wild. The response of H. cunea to repellent tree species and volatiles was determined using insect electrophysiological technique and Y-tube olfactometer test. H. cunea 5th, 6th instar larvae and virgin females were significantly more repulsive to the branches of Larix gmelinii and Syringa oblata than to blank control (P<0.05). Two mutual antennal active volatile compounds (α-pinene and (+)-limonene) from the branches of two tree species were identified by gas chromatography-electroantennographic detection/mass spectrometry (GC-EAD/MS) and electroantennography (EAG) responses of H. cunea females and males existed significant dose-dependent relationship (P<0.05). The highest EAG response value was induced at the highest concentration (100 µL/mL). In addition, 2 volatile compounds (100 µL/mL) had significant repellent effects on H. cunea 4-6th instar larvae and adults (P<0.05), and could notably inhibit the host (Salix matsudana) selection of 5th and 6th instar larvae and both sex adults (P<0.05). In conclusion, α-pinene and (+)-limonene as potential candidates can repellent H. cunea 4-6th larvae or adults, and play an important role in effective green prevention and control.

“…Besides α-pinene, volatile organic compounds (VOCs) from P. tabuliformis also includes limonene, β-pinene, and α-caryophyllene [ 61 ]. Xu et al [ 62 ] found that the VOCs from P. koraiensis included α-pinene, β-pinene, and sabinene. Insects can successfully survive on their host plants by producing detoxifying enzymes, e.g., P450s, UGTs, and CEs [ 25 , 30 , 41 ].…”

Background In many insect species, the larvae/nymphs are unable to disperse far from the oviposition site selected by adults. The Sakhalin pine sawyer Monochamus saltuarius (Gebler) is the newly discovered insect vector of the pine wood nematode (Bursaphelenchus xylophilus) in China. Adult M. saltuarius prefers to oviposit on the host plant Pinus koraiensis, rather than P. tabuliformis. However, the genetic basis of adaptation of the larvae of M. saltuarius with weaken dispersal ability to host environments selected by the adult is not well understood. Results In this study, the free amino and fatty acid composition and content of the host plants of M. saltuarius larvae, i.e., P. koraiensis and P. tabuliformis were investigated. Compared with P. koraiensis, P. tabuliformis had a substantially higher content of various free amino acids, while the opposite trend was detected for fatty acid content. The transcriptional profiles of larval populations feeding on P. koraiensis and P. tabuliformis were compared using PacBio Sequel II sequencing combined with Illumina sequencing. The results showed that genes relating to digestion, fatty acid synthesis, detoxification, oxidation-reduction, and stress response, as well as nutrients and energy sensing ability, were differentially expressed, possibly reflecting adaptive changes of M. saltuarius in response to different host diets. Additionally, genes coding for cuticle structure were differentially expressed, indicating that cuticle may be a potential target for plant defense. Differential regulation of genes related to the antibacterial and immune response were also observed, suggesting that larvae of M. saltuarius may have evolved adaptations to cope with bacterial challenges in their host environments. Conclusions The present study provides comprehensive transcriptome resource of M. saltuarius relating to host plant adaptation. Results from this study help to illustrate the fundamental relationship between transcriptional plasticity and adaptation mechanisms of insect herbivores to host plants.

“…However, fieldwork has indicated that the only infested conifer species in China to date is P. sylvestris var. mongolica, even when other potential hosts are present in the same forest [37]. As is characteristic of invasive pests, S. noctilio appears to be harmless in the natural distribution area of its favorite host tree species.…”

Sirex noctilio F. (Hymenoptera: Siricidae: Siricinae), a new invasive species in China, is a significant international forestry pest which, transported via logs and related wood packing materials, has led to environmental damage and substantial economic loss in many countries around the world. It was first detected in China in 2013, and since then infestations have been found in 18 additional sites. Using a 322 bp fragment of the mitochondrial barcode gene COI, we studied the genetic diversity and structure of S. noctilio populations in both native and invaded ranges, with a specific focus in China. Twelve haplotypes were found across the native and invaded distribution of the pest, of which three were dominant; among these there were only one or two mutational steps between each pair of haplotypes. No obvious genetic structure was found other than in Chinese populations. China has a unique and dominant haplotype not found elsewhere, and compared with the rest of the world, the genetic structure of Chinese populations suggested a multiple invasion scenario.
