Cryphalus piceae attacks various economically important conifers. Similar to other bark beetles, Cr. piceae plays a role as a vector for an assortment of fungi and nematodes. Previously, several ophiostomatoid fungi were isolated from Cr. piceae in Poland and Japan. In the present study, we explored the diversity of ophiostomatoid fungi associated with Cr. piceae infesting pines in the Shandong Province of China. We isolated ophiostomatoid fungi from both galleries and beetles collected from our study sites. These fungal isolates were identified using both molecular and morphological data. In this study, we recovered 175 isolates of ophiostomatoid fungi representing seven species. Ophiostoma ips was the most frequently isolated species. Molecular and morphological data indicated that five ophiostomatoid fungal species recovered were previously undescribed. Thus, we proposed these five novel species as Ceratocystiopsis yantaiensis, C. weihaiensis, Graphilbum translucens, Gr. niveum, and Sporothrix villosa. These new ophiostomatoid fungi add to the increasing number of fungi known from China, and this evidence suggests that numerous novel taxa are awaiting discovery in other forests of China.

With the rapid development of big data mining technology in the Chinese commercial field, the news topic prediction becomes increasingly important. Since the accuracy of Chinese news topic classification can directly affect the personalized recommendation effect of the Chinese news system and then affect business profits, the news category prediction performance needs to be higher as possible. With the great success of the BERT model in the past two years, using the BERT model alone has achieved extremely good performance on Chinese text classification tasks. Therefore, using the advantages of the BERT to study more effective methods for the Chinese news classification will become more meaningful. In this paper, we propose a model that combines the advantages of both BERT and the long short-term memory (LSTM) network, named BERT ensemble LSTM-BERT(BERT-LB). Our method is more effective than using BERT alone. This model uses a three-step method to calculate and integrate Chinese news text features. Besides, we use two datasets to evaluate our method and other baseline methods. We demonstrate that the proposed method has the promising ability to predict Chinese news topics and prove its generalization ability.

The Palearctic Atemelia Herrich-Schäffer, 1853 is reviewed. Two species are treated, one of which is described as new: A. fusca Liu, sp. nov. The genus Atemelia is recorded in China for the first time, and it is also newly recorded from the Eastern Palearctic region. Larvae of A. fusca sp. nov. mine leaves of Ulmus pumila (Ulmaceae), sharing the same host plant genus with another leaf miner A. torquatella (Lienig & Zeller, 1846) from Europe, but they are distinctive from the Nearctic and the Neotropical Atemelia species in host plant families and life styles. Photographs of adults and genitalia of the Palearctic Atemelia are provided. Additional photographs of immature stages, leafmines, and host plant are provided for the new species. In addition, three DNA barcodes are provided for A. fusca sp. nov.

Bees play a very important role in pollination, especially western honey bees, which contribute upwards of billions of dollars concerning crop pollination. Hairiness plays an important role in pollination success by transporting pollen, and pollen intake, but there is a lack of detailed studies on the morphological mechanisms. The hairiness trait is barely discussed in pollinator trait analysis because of the lack of systematic techniques used to measure hairiness. This paper reports a novel method that is used to measure the hair length of different body parts of a western honey bee through a stereomicroscope equipped with live measurement module software. Scanning electron microscope (SEM) was used to update the knowledge regarding the hair structure of a western honey bee. We explained different types of hairs, hair branches, and their distributions on different body parts, which are discussed in detail. A positive correlation was found between hair length and the number of branches on all body parts. Five types of branches were observed, and these branches vary with different body parts. Our study provides sufficient details about the hair morphology of the western honey bee and a new methodology for measuring hair length. This methodology will improve the knowledge about understanding the pollination efficiency of the western honey bee.

Purpose: Previous studies suggest that homocysteine (Hcy) may be involved in the pathogenesis of bipolar disorder (BD) and major depressive disorder (MDD) by influencing glutamatergic transmission, inflammation, and other mechanisms. There are no established biomarkers to distinguish BD from MDD. This study aims to compare Hcy levels between BD and MDD. Patients and Methods: We collected medical records of patients aged 14– 75 admitted to the hospital from January 1 to July 1, 2022 with a discharge diagnosis of MDD or BD, including all examinations of patients at admission (acute phase) and discharge (non-acute phase). We measured Hcy levels in healthy controls (HC). Results: The analysis included 104 patients with MDD, 103 patients with BD, and 80 HC. Hcy levels were higher in the MDD and BD group than in the HC group and higher in the BD group than in the MDD group, both in the acute and non-acute phases (all P < 0.05). There was no significant difference in Hcy levels between the psychotropic medication users and non-users in the BD or MDD group (all P > 0.05). Multivariate logistic regression analysis only for the MDD and BD group indicated that the likelihood of BD diagnosis was significantly associated with Hcy levels (in the acute phase: OR = 1.052, P = 0.016; in the non-acute phase: OR = 1.101, P < 0.001) after controlling for gender, age, and metabolic indicators. Conclusion: Our study suggests that Hcy levels were elevated in MDD and BD patients and were higher in BD patients than in MDD patients, which provides evidence for a possible relationship between one-carbon metabolism and the pathogenesis of BD. Besides, Hcy may be one of the potential biomarkers to distinguish BD from MDD.

TheAntispilaspecies feeding on Vitaceae from Shandong Peninsula, China are treated.AntispilakunyuensisLiu,sp. n., feeding onAmpelopsishumulifolia, is described as new to science, andA.uenoiKuroko, 1987, feeding onVitisamurensis, is recorded as new for China.Vitisamurensisis documented as a new host plant forA.uenoi. The adult male and female, host plant and typical patterns of leaf-mines of both species are illustrated, as are male and female genitalia and venation. The venation and the paired tufts of scales on the 7^thabdominal segment in male are illustrated forA.uenoifor the first time. DNA barcodes of both species are also provided, together with a neighbor-joining tree for facilitating species delimitation.
