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.

Mutualism between insects and symbiotic bacteria drives insect evolution, insecticide resistance is affected by bacteria, increasing the complexity of pest resistance. This study evaluated sublethal transgenerational effects neonicotinoid nitenpyram on population dynamics Acyrthosiphon gossypii measured its impact bacterial community. The results showed that LC20 (2.49 mg·L−1) significantly reduced fecundity lifespan parent G0 generation A. gossypii, had similar inhibitory G1 G2 generations. Compared with those control group, parameters λ (finite rate increase), R0 (net reproductive rate), r (intrinsic increase rate) were reduced, but mean time (T) was increased. Nitenpyram treatment biological traits also changed relative abundance Buchnera Sphingomonas in three consecutive generations G0-G2. Under treatment, decreased G0, while increased G2, decreased. Our findings may provide a new perspective for evaluating potential pesticides aphids.

Insecticides play a crucial role in safeguarding crops from pest. However, prior to their release, it is essential assess the efficacy and potential effects of these protectants. Flupyradifurone (FBF) sulfoxaflor (SFX), two insecticides commonly used control aphids, have been found exert negative on growth development Binodoxys communis Gahan, beneficial parasitic wasp that targets aphids. remains unknown if FBF SFX influence symbiotic bacteria residing within B. communis. In this study, 16SrRNA sequencing was utilized populations symbionts exposed sublethal concentrations (LC10 LC25) SFX. The treatment groups exhibited similar bacterial community structures, with Bacteroidota identified as dominant phylum each. After exposure SFX, diversity richness (Firmicutes, Bacteroidota, Actinobacteriota) changed notably. different durations exerted distinct microbial community. For instance, stress resulted decrease Akkermansia an increase Escherichia Shigella 1h after exposure, both returning baseline levels 3d. contrast, caused reduction presence 1h, which persisted even This study represents first assessment communis, expanding our understanding how natural enemies relationships. provides theoretical guidance for field applications well reasonable basis exploring chemical resistance conferred by bacteria.
