Comparative Metabolic Defense Responses of Three Tree Species to the Supplemental Feeding Behavior of .

L. can attract adult Asian longhorned beetle (ALB), (Motschulsky), and kill their offspring by gum secretion in oviposition scars. This plant has the potential to be used as a dead-end trap tree for ALB management.

Interactions at the Oviposition Scar: Molecular and Metabolic Insights into 's Resistance Response to .

The Russian olive (), which functions as a "dead-end trap tree" for the Asian long-horned beetle () in mixed plantations, can successfully attract Asian long-horned beetles for oviposition and subsequently kill the eggs by gum. This study aimed to investigate gum secretion differences by comparing molecular and metabolic features across three conditions-an oviposition scar, a mechanical scar, and a healthy branch-using high-performance liquid chromatography and high-throughput RNA sequencing methods. Our findings indicated that the gum mass secreted by an oviposition scar was 1.

Cold tolerance and metabolism of red-haired pine bark beetle Hylurgus ligniperda (Coleoptera: Curculionidae) during the overwintering period.

Hylurgus ligniperda invaded Shandong, China, through imported forest timber, posing a threat to China's forest health. Exotic insects with broad environmental tolerance, including low temperatures, may have a better chance of surviving the winters and becoming invasive. Understanding the cold-tolerance strategies of H.

Gut Bacteria Associated With (Coleoptera: Cerambycidae) and Their Possible Roles in Host Plant Adaptations.

(Coleoptera: Cerambycidae) is an important native pest in the pine forests of northeast China and a dispersing vector of an invasive species . To investigate the bacterial gut diversity of larvae in different host species, and infer the role of symbiotic bacteria in host adaptation, we used 16S rRNA gene Illumina sequencing and liquid chromatography-mass spectrometry metabolomics processing to obtain and compare the composition of the bacterial community and metabolites in the midguts of larvae feeding on three host tree species: , var. , and Metabolomics in xylem samples from the three aforementioned hosts were also performed.

Transcriptomic and Metabolomic Data Reveal the Key Metabolic Pathways Affecting (Staudinger) (Lepidoptera: Cossidae) Larvae During Overwintering.

(Staudinger) (Lepidoptera: Cossidae) is a woodboring insect feeding on , , and , as well as many other species used for urban greening and plain afforestation in northern China, including the temperate north. There is also a risk that could spread through the transportation of seedlings, thereby increasing urban greening costs. However, how increases the cold tolerance then reduces it to survive winter temperature below 0°C remains unclear.

Overwintering Larval Cold Tolerance of (Hymenoptera: Siricidae): Geographic Variation in Northeast China.

(Hymenoptera: Siricidae) is an invasive pest that has spread and established in many regions worldwide. However, its cold tolerance strategy is still unclear. We measured the supercooling point (SCP) and the lower lethal temperature (LLT) of overwintering larvae during three overwintering periods in four geographically separated populations in China.

Factors Influencing Cold Hardiness during Overwintering of Streltzoviella insularis (Lepidoptera: Cossidae).

Streltzoviella insularis (Staudinger) (Lepidoptera: Cossidae) is a woodboring pest that severely damages urban and plain afforestation trees in northern China. Cold hardiness is an important strategy for the insect to survived during low winter temperatures. Understanding the strategy of S.
