Temporal variation in infection levels and reproductive traits of the acanthocephalan Pseudoleptorhynchoides lamothei in the blue sea catfish Ariopsis guatemalensis (Günther, 1864).
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.
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.
