于2013年和2018年在河南信阳新县与浉河共采集到3号鼩鼱成年个体标本,基于齿色特征初步鉴定为劳亚食虫目鼩鼱科麝鼩属(Crocidura)物种。对所采3号标本的Cyt b基因进行PCR扩增和测序,测序结果与GenBank数据库进行比对,并通过构建系统发育关系树进一步明确所采3只标本的分类地位。根据标本形态、头骨特征,结合分子生物学证据,确定该物种为台湾灰麝鼩(C.tanakae),为河南哺乳动物分布新记录种。标本现存于郑州大学生物多样性与生态学研究所(编号分别为IBE20131005、IBE2018100501和IBE2018100502)。 相似文献

Taeniasis has been known as one of the prevalent parasitic infections in Korea. Until recently, Taenia saginata had long been considered a dominant, and widely distributed species but epidemiological profiles of human Taenia species in Korea still remain unclear. In order to better understand distribution patterns of human Taenia tapeworms in Korea, partial nucleotide sequences of mitochondrial cox1 and ITS2 (internal transcribed spacer 2) were determined, along with morphological examinations, on 68 Taenia specimens obtained from university museum collections deposited since 1935. Genomic DNA was extracted from formalin-preserved specimens. Phylogenetic relationships among the genotypes (cox1 haplotype) detected in this study were inferred using the neighbor-joining method as a tree building method. Morphological and genetic analyses identified 3 specimens as T. solium, 51 specimens as T. asiatica, and 14 specimens as T. saginata. Our results indicate that all 3 Taenia tapeworms are sympatrically distributed in Korea with T. asiatica dominating over T. saginata and T. solium. 相似文献

Seasonal fluctuations in field populations of Meloidogyne incognita, Pratylenchus zeae, P. brachyurus, Criconemoides ornatus, Trichodorus christiei, and Helicotylenchus dihystera on monocultured corn, cotton, peanut, and soybean were determined monthly for 4 yr. Population densities of M. incognita were greater in corn and cotton plots than in peanut and soybean plots from July until January. Those of Pratylenchus spp. were greater on corn and soybean than on cotton and peanut during all months except May and June. C. ornatus populations were greater on corn and peanut than on cotton and soybean during all months. C. ornatus on corn and peanut was more numerous in July than in other months. There was no significant increase in populations of T. christiei, except on corn in June. H. dihystera was greater in cotton and soybean plots than in corn and peanut plots from August through December. 相似文献

Xiphinema specimens were collected from orchards in southeastern, northeastern, and western New York. Total length, distance of vulva from anterior end, spear length (odontostyle plus odontophore), body diameter at vulva, tail length, anal body diameter, and length and diameter of hyaline tail tip were measured on fixed, glycerol-infiltrated adult females. Most specimens were identified as X. americanum or X. rivesi, but one western New York population was identified as X. californicum (a new record for New York). Multivariate analyses indicated that, with one exception, western New York populations of both X. americanum and X. rivesi were smaller and slimmer than their eastern counterparts. Regional differences were generally larger than differences attributed to host species. 相似文献
