Microbial partners include at least one obligate mutualistic filamentous fungus used as food for larvae and adults, and potentially secondary filamentous fungi, yeasts, and bacteria. Beetles in the genus <i>Xyleborus</i> possess paired pre-oral mycangial structures located within the head on either side of the mouth parts. Mycangia develop in pupae, with newly emerged adults acquiring partners from the environment. However, information concerning the cellular structure and function of <i>Xyleborus</i> mycangia remains limited. We show that in <i>X. affinis</i>, mycangia are lined with a layer of striated dense material, enclosing layers of insect epithelial cells, with diverse spine-like structures. Larger (5-10 μm) projections were concentrated within and near the entrance of mycangia, with smaller filaments (4-8 μm) within the mycangia itself. Rows of \"eyelash\" structures lined the inside of mycangia, with fungal cells free-floating or in close association with these projections. Serial sections revealed mandibular articulations, and mandibular, pharyngeal, and labial muscles, along with the mycangial entry/exit channel. Sheets of comb-like spines at the mycangial entrance and opposite the mycangia attached to the roof of the labrum or epipharynx may serve as an interlocking mechanism for opening/closing the mycangia and guiding fungal cells into entry/exit channels. Additionally, mandibular fibra (muscle tissue) potentially enervating and affecting the mechanism of mycangial functioning were noted. These data add crucial mechanistic detail to the model of pre-oral mycangia in <i>Xyleborus</i> beetles, their cellular structures, and how they house and dispense microbial symbionts.</p>","PeriodicalId":13642,"journal":{"name":"Insects","volume":"16 6","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144484198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to investigate how the distribution of <i>Glipa</i> may respond to climate change using a species-level MaxEnt based model with 297 geographic distribution data points and seven bioclimatic environmental variables. The study showed that the MaxEnt model had a high predictive accuracy, with an Area Under the Curve (AUC) value of 0.963. The maximum temperature of the warmest month, mean annual precipitation, and mean precipitation of the driest quarter were the three most important factors affecting the distribution of <i>Glipa</i>. Currently, the suitable distribution areas of <i>Glipa</i> are mainly located in East Asia, Southeast Asia, eastern North America, South America, and central and western Africa.

Under the SSP585 scenario in the 2070s, the suitable habitat area is projected to expand by 53.89% compared to the present.

(2) Methods: Five &lt;i&gt;Beauveria bassiana&lt;/i&gt; strains were evaluated for virulence against fourth-instar larvae. And the levels of T-AOC and MDA in the larvae infected by each strain were measured. To assess larval responses to different strains, we measured the activities of six enzymes (SOD, CAT, POD, PPO, CarE, GST) and the levels of GSH and H&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;2&lt;/sub&gt; in larvae treated with each strain. Additionally, the infection process of highly pathogenic &lt;i&gt;B. bassiana&lt;/i&gt; in larvae was explored using scanning electron microscopy (SEM).

The T-AOC of larvae treated with strain CGMCC3.2055 was inhibited within 48 h.
