Previous studies have indicated that the prevalence rate of hypertension in adolescents is high, but it has not received much attention and the influencing factors are unclear, especially in Yunnan Province, China. A cluster sampling method was used to investigate 4781 freshmen in a college in Kunming, Yunnan Province from November to December. Demographic and lifestyle data were collected using questionnaires, and height, weight and blood pressure were measured. Decision tree model of hypertension in college students was established by Chi-square automatic interactive detection method. Prevalence of prehypertension of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were detected in 33.9% and 32.1%, respectively. Prevalence of hypertension of SBP and DBP was detected in 1.2% and 7.2%, respectively. The hypertension and prehypertension decision tree of SBP has gender (χ2 = 728.64, p <.001) at the first level and body mass index (BMI) (boys: χ2 = 55.98, p <.001; girls: χ2 = 79.58, p <.001) at the second level. The hypertension and prehypertension decision tree of DBP has gender (χ2 = 381.83, p <.001) at the first level, BMI (boys: χ2 = 40.54, p <.001; girls: χ2 = 48.79, p <.001) at the second level, only children (χ2 = 6.43, p =.04) and red wine consumption (χ2 = 8.17, p =.017) at the third level. The present study suggests that gender, BMI, only children and red wine consumption were the main factors affecting hypertension in college students in southwest border areas of China. Hypertension in Chinese adolescent is generally ignored. This study first reports the prevalence of hypertension in adolescents in Yunnan Province, China. Four thousand seven hundred and eighty-one freshmen were surveyed and height, weight and blood pressure were measured. A decision tree model was used to analyze the predictors of hypertension. The study demonstrated that gender, BMI, only children and red wine predict hypertension in adolescents. [ABSTRACT FROM AUTHOR]

New information on the genus Psychostrophia Butler, 1877 is provided. A new species, Psychostrophia micronymphidiaria Huang & Wang, sp. nov., is described from western, northern and northwestern Yunnan Province, southwestern China; it is similar to P. nymphidiaria (Oberthür, 1893) which is widely distributed in eastern, southern, western and central China. A new synonym is established: Psychostrophia nymphidiaria (Oberthür, 1893) (= Stiboges lushanica Chou & Yuan, 2001, syn. nov.). Some other taxonomic and nomenclatural notes on the genus are presented. A key to the species of the genus Psychostrophia is provided. [ABSTRACT FROM AUTHOR]

Bark beetles and their associated fungi, which cause forest decline and sometimes high mortality in large areas around the world, are of increasing concern in terms of forest health. Three Tomicus spp. (T. brevipilosus, T. minor and T. yunnanensis) infect branches and trunks of Pinus yunnanensis and P. kesiya in Yunnan Province, in south-western China. Tomicus spp. are well known as vectors of ophiostomatoid fungi and their co-occurrence could result in serious ecological and economic impact on local forest ecosystems. Nonetheless, knowledge about their diversity, ecology, including pathogenicity and potential economic importance is still quite rudimentary. Therefore, an extensive survey of ophiostomatoid fungi associated with these Tomicus species infesting P. yunnanensis and P. kesiya was carried out in Yunnan. Seven hundred and seventy-two strains of ophiostomatoid fungi were isolated from the adult beetles and their galleries. The strains were identified based on comparisons of multiple DNA sequences, including the nuclear ribosomal large subunit (LSU) region, the internal transcribed spacer regions 1 and 2, together with the intervening 5.8S gene (ITS) and the partial genes of ß-tubulin (TUB2), elongation factor 1a (TEF1-a) and calmodulin (CAL). Phylogenetic analyses were performed using maximum parsimony (MP) as well as maximum likelihood (ML). Combinations of culture features, morphological characters and temperature-dependent growth rates were also employed for species identification. Eleven species belonging to five genera were identified. These included six known species, Esteya vermicola, Leptographium yunnanense, Ophiostoma brevipilosi, O. canum, O. minus and O. tingens and four novel taxa, described as Graphilbum anningense, O. aggregatum, Sporothrix pseudoabietina and S. macroconidia. A residual strain was left unidentified as Ophiostoma sp. 1. The overall ophiostomatoid community was by far dominated by three species, representing 87.3% of the total isolates; in decreasing order, these were O. canum, O. brevipilosi and O. minus. Furthermore, the ophiostomatoid community of each beetle, although harbouring a diversity of ophiostomatoid species, was differentially dominated by a single fungal species; Ophiostoma canum was preferentially associated with and dominated the ophiostomatoid community of T. minor, whereas O. brevipilosi and O. minus were exclusively associated with and dominated the ophiostomatoid communities of T. brevipilosus and T. yunnanensis, respectively. Eight additional species, representing the remaining 12.7% of the total isolates, were marginal or sporadic. These results suggested that sympatric Tomicus populations are dominated by distinct species showing some level of specificity or even exclusivity. [ABSTRACT FROM AUTHOR]

The six species of the genus Andraca Walker hitherto known from China are reviewed, and a new species, A. gongshanensis, sp. n., described from Yunnan Province, China. Adults and male genitalia of all examined species are illustrated, together with a distributional map. A key to all seven Chinese Andraca species is provided. The types of the new species are deposited in SCAU (South China Agricultural University, Guangzhou, China) and HUNAU (Hunan Agricultural University, Changsha, China). [ABSTRACT FROM AUTHOR]

The lycaenid genus Phengaris (s. str.) from mainland China is briefly characterized, and a short identification key presented. Phengaris xiushani sp. n. is described and illustrated from northwestern Yunnan. The new species is similar to P. daitozana from Taiwan with respect to the wing maculation in having a whitish upperside and much smaller spots on the underside. Genitalia features are similar to Phengaris (Maculinea) nausithous from the western Palaearctic region. The type specimens are kept in the Insect Collection, South China Agricultural University, Guangzhou, China (SCAU), and the "S enckenberg Museum für Tierkunde" in Dresden, Germany (MTD).
