Abstract

Current data on reproductive biology and population dynamics of the acanthocephalans are scarce mainly in regions from the tropical Pacific. An analysis was done to identify possible factors that influence variation in infection levels of the acanthocephalan Pseudoleptorhynchoides lamothei Salgado-Maldonado, 1976 in its final host, the blue sea catfish Ariopsis guatemalensis (Günther, 1864), and describe its main reproductive traits. A total of 1,094 A. guatemalensis were collected from Tres Palos Lagoon from August 2014 to December 2015. Prevalence of P. lamothei varied from 1.47% to 38.33%, and mean abundance from 0.03 to 4.44 helminths per examined host. In female P. lamothei relative fecundity increased with total length. Temporal variations in P. lamothei infection levels were attributed mainly to changes in host feeding and reproductive behaviour in response to local environmental factors as climatic season, and variations in water temperature.

蓝海危地马拉Ariopsis鲶鱼中棘头虫Pseudoleptorhynchoides lamothei感染水平和生殖性状的时间变化(g nther, 1864)。

目前关于棘头类动物生殖生物学和种群动态的数据很少，主要集中在热带太平洋地区。本文分析了棘头绦虫1976年在其最终宿主——危地马拉蓝海鲶鱼Ariopsis guatemalensis (g nther, 1864)中感染水平变化的可能影响因素，并描述了其主要生殖特征。2014年8月至2015年12月在特雷斯帕洛斯湖共采集到危地马拉伊蚊1094只。拉莫线虫的流行率为1.47% ~ 38.33%，平均丰度为0.03 ~ 4.44个。在雌花中，相对繁殖力随总长度的增加而增加。拉莫氏疟原虫感染水平的时间变化主要归因于宿主对气候季节等当地环境因素的摄食和繁殖行为的变化以及水温的变化。

期刊介绍： FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
