Liriomyza trifolii is an economically-significant polyphagous pest that infests plants grown in both field and greenhouse conditions. Unfortunately, the lack of genomic resources has hindered our understanding of its ecological adaptation and invasiveness. To address this, we assembled a chromosome-level genome sequence of L.

Background: Jiangsu Province is located on the southeast coast of China and lacks high-altitude mountains, with only a few hilly areas mainly distributed in its southern region. In recent years, We investigated the diversity of Plecoptera species in the major mountainous and forested areas of Jiangsu, recording a total of 20 species across 12 genera and five families.

New Information: In this paper, we examined the materials of from Jiangsu and described a new species, In addition, detailed English descriptions and colour pictures of are provided for the first time.

Article Synopsis
  • Host hemolymph serves as a crucial environment for endoparasitoid growth, particularly for Chilo suppressalis larvae, which respond to parasitism by generating many granulocytes.
  • High temperatures hinder these granulocytes' functions, causing apoptosis and affecting other immune responses by activating apoptotic pathways in cells like prohemocytes.
  • The study identifies Cscaspase-8 in C. suppressalis, showing that while its expression increases under stress from heat and parasitism, silencing this gene does not significantly impact larval survival, although it causes developmental delays in Cotesia chilonis larvae, enhancing our understanding of insect apoptosis regulation.

The leafminer Liriomyza trifolii causes severe economic damage on ornamental and horticultural crops in China. Rapid cold hardening (RCH) is a phenomenon where cold tolerance in insects can be significantly enhanced after a short-term acclimation to low temperatures. In this study, the regulation of transcription in response to cold hardening was investigated in L.

Wolbachia are common heritable endosymbionts that influence many aspects of ecology and evolution in various insects, yet Wolbachia-mediated intracellular metabolic responses to temperature stress have been largely overlooked. Here, we introduced the Wolbachia strain wLhui from the invasive Liriomyza huidobrensis (Blanchard) into a Drosophila Schneider 2 cell line (S2) and investigated the metabolite profile of wLhui-infected (S2_wLhui) and uninfected cell lines (S2_wu) under short-term exposure to either high (37°C), moderate (27°C), or low (7 and 17°C) temperatures. We find that Wolbachia infection, temperature stress, and their interactions significantly affect cellular metabolic profiles.

Unlabelled: Arthropods harbor complex microbiota that play a pivotal role in host fitness. While multiple factors, like host species and diet, shape microbiota in arthropods, their impact on community assembly in wild insects remains largely unknown. In this study, we surveyed bacterial and fungal community assembly in nine sympatric wild insect species that share a common citrus fruit diet.

Environmental heterogeneity partly drives microbial succession in arthropods, while the microbial assembly mechanisms during environmental changes remain largely unknown. Here, we explored the temporal dynamics and assembly mechanisms within both bacterial and fungal communities in (Blanchard) during the transition from field to laboratory conditions. We observed a decrease in bacterial diversity and complexity of bacterial-fungal co-occurrence networks in leaf miners transitioning from wild to captive environments.

Article Synopsis
  • Understanding the phylogeography of invasive species, like Pomacea canaliculata and Pomacea maculata in China, helps in creating better management and prevention strategies for their spread.
  • This study focuses on analyzing the genetic diversity and population structure of P. canaliculata using mitochondrial and ribosomal DNA, revealing notable genetic variation but no clear geographical population structure.
  • Findings indicate that the COI gene shows more genetic diversity compared to the ITS1 gene, enhancing knowledge of how these species invade and disperse across China.

Background: Hainan Province is an island in the south of China and belongs to the Oriental Region. It has a unique geographical location and superior climatic conditions, providing a good living environment for Leuctridae insects. However, the species richness of the stonefly family Leuctridae in Hainan is low.

As an environmental factor, temperature impacts the distribution of species and influences interspecific competition. The molecular chaperones encoded by small heat shock proteins (sHsps) are essential for rapid, appropriate responses to environmental stress. This study focuses on , which encodes a temperature-responsive in , an insect pest that infests both agricultural and ornamental crops.

Inhibitor of apoptosis proteins (IAPs) are crucial components of apoptosis that perform vital roles in the regulation of caspase activity in organisms. In this study, two IAPs genes were identified from , the dominant parasitic wasp of . IAP1 gene is a typical IAP and contains two BIR domains and a RING domain, whereas IAP gene is an atypical IAP1 only containing two BIR domains.

Article Synopsis
  • Liriomyza trifolii is an invasive pest that harms horticultural crops, with its distribution affected by temperature, showcasing differing thermal adaptability among populations from Hainan (HN) and Jiangsu (JS).
  • Research reveals that the HN population survives better and endures higher temperatures than the JS population, with distinct gene expression patterns under heat stress where HN shows higher expression of heat shock proteins.
  • The study enhances understanding of molecular mechanisms behind temperature adaptation in L. trifolii and has implications for managing this pest across different regions.
