Abstract For insects whose larvae are incapable of moving between food resources, the selection oviposition sites by females is critical to survival and development their offspring. In such insects, it known that utilise benefit from conspecific cues for choice. Studying how information behaviour conspecifics affects egg-laying decision-making crucial understanding biology which can lead novel strategies pest management. We focused on reproductive Asian long-horned beetle Anoplophora glabripennis , has become an invasive species throughout world. Here, we show A. avoids already containing during decision-making. The field survey measuring distance neighbouring scars (in this species, make through bark host branches laying eggs) suggested not random. laboratory oviposition-choice bioassays, made less other than those without scars. addition, female was also deterred presence own Our results indicate avoiding (and own) traces realises fitness as reducing resource competition among larvae. This study provides insights into longhorn beetle, useful developing environmentally friendly control methods deterrents.

Elaeagnus angustifolia L. can attract adult Asian longhorned beetle (ALB), Anoplophora glabripennis (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. However, there is limited understanding of attraction ability biochemical defense response E. ALB. In this study, we conducted host selection experiments with then performed physiological assays on twigs from different species before after feeding. We analyzed differential metabolites using liquid chromatograph–mass spectrometer method. The results showed that ALB’s feeding preference was > P.× xiaohei var. gansuensis P. alba pyramidalis. After feeding, content soluble sugars, proteins, flavonoids, tannins decreased significantly all species. three comparison groups, total 492 were identified (E. angustifolia:195, gansuensis:255, pyramidalis:244). Differential divided into overlapping specific analysis. 7-isojasmonic acid, zerumbone, salicin upregulation silibinin, catechin, geniposide, angustifolia, increased being damaged. enriched KEGG pathways indicated activated tyrosine metabolism biosynthesis phenylpropanoids species, particularly high enrichment flavonoid pathway angustifolia. study provides metabolic strategies against proposes candidate serve biomarkers, potentially offering valuable insights control measure
