Abstract Wolbachia are common heritable endosymbionts that influence many aspects of ecology and evolution in various insects, yet ‐mediated intracellular metabolic responses to temperature stress have been largely overlooked. Here, we introduced the strain wLhui from invasive Liriomyza huidobrensis (Blanchard) into a Drosophila Schneider 2 cell line (S2) investigated metabolite profile wLhui‐infected (S2_wLhui) uninfected lines (S2_wu) under short‐term exposure either high (37°C), moderate (27°C), or low (7 17°C) temperatures. We find infection, stress, their interactions significantly affect cellular profiles. Most significantly, when comparing changes metabolites between S2_wLhui S2_wu, glycerophospholipids, amino acids, fatty acids associated with pathways, microbial metabolism diverse environments, other pathways were accumulated at Our findings suggest ‐induced physiological which may turn fitness adaptive ability its host as an species.

The physiological changes and the impact of rapid cold hardening on the survival ability of Dastarcus helophoroides (Fairmaire) (Coleoptera: Bothrideridae) under cold stress

Physiological Entomology, Год журнала: 2025, Номер unknown

Abstract Dastarcus helophoroides (Fairmaire) serves as an ideal biological control agent for forest beetles. However, its survival ability at low temperatures is a critical factor use in colder regions. This study investigates the ability, supercooling point (SCP), impact of rapid cold hardening (RCH) and physiological changes D. under stress. SCPs adults that underwent RCH were lower than those cultured room temperature, with −25.1°C −16.9°C, respectively. As stress temperature decreased test, also diminished, reaching lowest rates −20°C across all observation time points test. induced by exhibited higher suggesting enhances resistance . The activities superoxide dismutase (SOD) catalase (CAT) increased decreased. With prolonged stress, activity lactate dehydrogenase (LDH) initially then increased. Both fat water content lowering temperature. These results provide insights into strategies

Changes in Metabolomics Profiles of Propylea japonica in Response to Acute Heat Stress

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(10), С. 4541 - 4541

Опубликована: Май 9, 2025

The ladybird beetle, Propylea japonica Thunberg (Coleoptera: Coccinellidae), is a widely distributed natural predator that crucial in controlling various agricultural pests China. Despite frequent references to its remarkable thermotolerance, the molecular mechanisms underlying thermotolerance remain poorly understood. Here, we investigated metabolomic changes P. following exposure acute heat stress (AHS) lasting 1 h at 39 °C and 43 populations from Zhengzhou (ZZ, warm temperate climate zone) Shenzhen (SZ, subtropical zone), representing distinct northern southern Chinese ecosystems. A total of 4165 4151 metabolites were detected positive negative ion modes, respectively. high proportion lipid lipid-like (35.5%) top 20 pathways containing highest number metabolites, implying membrane fluidity modulation energy metabolism restructuring, served as core adaptive mechanism confronting thermal stress. SZ25 vs. SZ39 exhibited significantly higher differentially expressed (DEMs), which predominantly enriched purine tryptophan pathways. This indicated these orchestrate adaptation SZ population by coordinating reprogramming, orchestrating antioxidant defense mechanisms, modulating neuroendocrine homeostasis dysregulation. Additionally, starch sucrose, arachidonic acid, fructose mannose also implicated. study enhances our understanding provides valuable reference for other insects.

Unveiling winter survival strategies: physiological and metabolic responses to cold stress of Monochamus saltuarius larvae during overwintering

Pest Management Science, Год журнала: 2024, Номер 80(11), С. 5656 - 5671

Опубликована: Июль 9, 2024

Monochamus saltuarius is a destructive trunk-borer of pine forest and an effective dispersal vector for pinewood nematode (PWN), causative agent wilt disease (PWD), which leads to major ecological disasters. Cold winter temperatures determine insect survival distribution. However, little known about the cold tolerance potential physiological mechanisms M. saltuarius.
