Abstract:
The present investigation was carried out to determine the prevalence of arthropoda and helminth parasites in sheep at Azimpur, Dhaka during February, 2012 to January, 2013. A Total of 60 hosts were examined and about 71.67% sheep were found to be infested with arthropod parasites. In sheep two species of arthropod parasites, Linognathus vituli (61.67%) and Damalinia caprae (68.33%) were identified as ecto-parasites. The prevalence of ectoparasites was higher during summer (85%), followed by winter (75%) and rainy (55%). The higher intensity was also recorded in summer (325.17±1.92). Lambs were found more susceptible (85.71%) than adult (80.95%) and young (56%) sheep and higher in female (77.27%) than in male (68.42%). Twelve species of helminth parasites were identified, of them, 3 trematodes, 3 cestodes and 6 nematodes, highest prevalence was shown by Strongyloides sp (71.67%) and lowest by Dictyocaulus sp. (3.33%); found comparatively higher in adults (85.71%) than in young (80%) and 28% in lambs. The male sheeps were more susceptible (81.58%) to helminth infection than female (72.73%). Prevalence of helminthes was found higher in winter (95%) season. The value of co-efficient of correlation between the prevalence and intensity of infestation of ectoparasites and helminth parasites in sheep were 0.95 and 0.978 respectively. In both cases these two variables differed significantly (P<0.01).Bangladesh J. Zool. 42(1): 45-55, 2014

Abstract:
Arthropoda is a phylum of invertebrates that has undergone remarkable evolutionary radiation, with a wide range of venomous animals. Arthropod venom is a complex mixture of molecules and a source of new compounds, including antimicrobial peptides (AMPs). Most AMPs affect membrane integrity and produce lethal pores in microorganisms, including protozoan pathogens, whereas others act on internal targets or by modulation of the host immune system. Protozoan parasites cause some serious life-threatening diseases among millions of people worldwide, mostly affecting the poorest in developing tropical regions. Humans can be infected with protozoan parasites belonging to the genera Trypanosoma, Leishmania, Plasmodium, and Toxoplasma, responsible for Chagas disease, human African trypanosomiasis, leishmaniasis, malaria, and toxoplasmosis. There is not yet any cure or vaccine for these illnesses, and the current antiprotozoal chemotherapeutic compounds are inefficient and toxic and have been in clinical use for decades, which increases drug resistance. In this review, we will present an overview of AMPs, the diverse modes of action of AMPs on protozoan targets, and the prospection of novel AMPs isolated from venomous arthropods with the potential to become novel clinical agents to treat protozoan-borne diseases.

Abstract:
A three-dimensionally and completely preserved phosphatized microfossil has been found in Cambrian–Ordovician boundary bed limestones of the Green Point Formation at Green Point, western Newfoundland, Canada. It represents a new form of larvae, previously described by D. Walossek and K.J. Müller from Upper Cambrian anthraconitic limestones ("Orsten"). These authors identified the fossils as instars of marine stem-group representatives of the "tongue worms," Pentastomida. Pentastomida are parasites that today infest various land tetrapods and are presumed to represent one of the closest extant relatives of the Euarthropoda. This new fossil possesses remarkably well-preserved trunk limb vestigia and anal region. It is another example of exceptional three-dimensionally preserved, phosphatized fossils of the Orsten type that is no longer spatiotemporally restricted to the Upper Cambrian of Sweden.

Abstract:
Carnivory is the consumption of one animal by another animal; among invertebrates in terrestrial and freshwater ecosystems this type of feeding can take three forms: predation, parasitoidism, and parasitism. Differences among these three functional modes involve (i) whether the duration of feeding on the prey item is quick or there is an accommodation, coevolutionary or otherwise, between the carnivore and the host prey; (ii) whether the prey or host is killed; (iii) whether single or multiple prey or host items are consumed during the carnivore's lifespan, and (iv) the relative sizes of the carnivore and its prey or host. Uniformitarian and nonuniformitarian evidence directly relating to the history of carnivory can be found in exceptionally preserved deposits from the mid-Paleozoic to the Recent, but such evidence is relatively rare because carnivores are the least represented trophic group in ecosystems. Six types of paleobiological data provide evidence for carnivory: taxonomic affiliation, fossil structural and functional attributes, organismic damage, gut contents, coprolites, and indications of mechanisms for predator avoidance.Only 12 invertebrate phyla have become carnivorous in the continental realm. Six are lophotrochozoans (Acanthocephala, Rotifera, Platyhelminthes, Nemertinea, Mollusca, and Annelida) and six are ecdysozoans (Nematoda, Nematomorpha, Tardigrada, Onychophora, Pentastoma, and Arthropoda). Most of these groups have poor continental fossil records, but the two most diverse—nematodes and arthropods—have comparatively good representation. The record of arthropods documents (i) the presence of predators among primary producers, herbivores, and decomposers in early terrestrial ecosystems; (ii) the addition later in the fossil record of the more accommodationist strategies of parasitoids and parasites interacting with animal hosts; (iii) the occurrence of simpler food-web structures in terrestrial ecosystems prior to parasitoid and parasite diversification; and (iv) a role for mass extinction in the degradation of food-web structure that ultimately affected carnivory. Future research should explore how different modes of carnivory have brought about changes in ecosystem structure through time. Despite numerous caveats and uncertainties, trace fossils left by predators on skeletons of their prey remain one of the most promising research directions in paleoecology and evolutionary paleobiology.

Full text
Abstract:
Records of pentastomid arthropods parasitic in Australian reptiles and mammals are reviewed, with particular reference to material collected recently. Specimens representative of six genera are described. Sebekia sp. from the estuarine crocodile, Crocodylusporosus, is the first record of the genus in Australia and probably represents a new species. A nymph with double hooks, from the dasyurid marsupial Satanellus hallucatus, is determined as Waddycephalus sp. This represents the first evidence of double hooks in nymphal forms of the genus and of the role of marsupials as intermediate hosts of Waddycephalus. Nymphs from the peramelid marsupial, Isoodon macrourus, and from S, hallucatus are determined as Armillifer australis Riley & Self, 1981; those from Perameles nasuta are identified as A. arborealis Riley & Self, 1981. These represent the first records of marsupials as intermediate hosts of Armillifer. Adults of the genus Elenia Heymons, 1932 are confirmed as parasites of varanid lizards. E. australis Heymons, 1932 is recognized and it is suggested that specimens described by Heymons (1939), allegedly from Varanus varius at Townsville, Qld, may represent a new species. The cosmopolitan porocephalid Linguatula serrata Frolich, 1789 is recorded from the nasopharynx of the dingo or wild dog and the validity of the indigenous species, L. dingophila Johnson, 1910 is discussed. The cephalobaenid Raillietiella amphiboluri Mahon, 1954 is reported from Amphibolurus barbatus.

Abstract:
For the first time, generalized data on parasites of two subspecies of arctic grayling (Thymallus arcticus pallasi and Th. a. mertensi) from the largest salmon rivers of the northern coast of the Okhotsk Sea, as the Taui, Yama and Gizhiga, are presented. In total, 39 species of parasites are found including 38 helminth species belonging to 26 genera, 19 families, 5 classes and 3 types (Plathelminthes, Nemathelminthes, and Acanthocephales), and 1 parasitic copepod (Crustacea; Arthropoda). Among the flatworms, trematodes have the highest species diversity — 19 species belonged to 8 genera of 6 families, and cestodes are presented by 6 species (6 genera of 5 families). Nematodes are presented by 8 species (8 genera of 5 families), and acanthocephalans — by 5 species (4 genera, 3 families, 2 classes). The graylings parasites are distributed with 2 ecological groups: the freshwater parasites including 29 species (4 cestodes, 16 trematodes, 5 nematodes, 3 acanthocephalans, and 1 copepod) and the marine parasites including 10 species (2 cestodes, 3 trematodes, 3 nematodes, and 2 acanthocephalans). Th. a. mertensi from the Taui River basin is distinguished by the highest diversity of parasites (32 species), their high diversity is observed for the same species from the Gizhiga (20 species), and for Th. a. pallasi from the Yama (24 species), as well. More than a half of helminths (22 species) are noted by medical and veterinary importance and/or are able to spoil organoleptic properties of the seafood.

Abstract:
Heteroxenous (multiple host) life histories are characteristic of many groups of parasitic protista and animals, including Zoomastigina, Apicomplexa, Mesozoa, Platyhelminthes, Nematoda, Acanthocephala, Pentastomida, and Arthropoda. Parasitic fungi, including the Chytridiomycota and the Dikaryomycota (ascomycetes and basidiomycetes), may also have heteroxenous life histories and have many features in common with parasites from other groups. In spite of many conceptual similarities, the study of parasitic fungi has occurred in isolation, resulting in the creation of a separate vocabulary and literature. Many of the concepts developed by zoologists are useful to mycologists and allow examination of parasitic fungi from new perspectives. These new perspectives reveal that heteroxenous fungi are not only similar to heteroxenous protistans and animals but that they also have unique characteristics of their own. Chief among these is a high level of endocyclic asexual reproduction, a phenomenon promoting exponential increases of infections in definitive host populations. Heteroxeny appears to have a number of benefits including (i) increased lifetime reproductive success, (ii) increased transmission efficiency (iii) enhanced effectiveness in colonizing ephemeral or periodically appearing hosts and hosts occurring in low population densities, (iv) maintenance or enhancement of overdispersed frequency distributions in host populations, and (v) enhancement of genetic exchange through multiple dispersal events. Key words: fungi, heteroxenous, parasite, life histories.

Abstract:
Many medically important diseases of man are caused by blood-sucking arthropods which serve as vectors for a wide range of viral, bacterial, protozoal and nematode infections (Table 1). Furthermore, serious economic losses are caused by the numerous arthropod parasites which infect domesticated animals (for examples, see Table 2). Among these the ixodid hard ticks are particularly important and it has been estimated that the global cost of hard tick infections is $7000 million per annum (F.A.O., 1984). Not surprisingly, there have been strenuous efforts to control infections caused by arthropods.

Abstract:
AbstractGongylonema ingluvicola and Spirocerca lupi are spirurid nematodes that require arthropod intermediate hosts in order to complete their life cycle. Beetles of the family Scarabaeidae are reported to serve as intermediate hosts for both these parasites. In this study selected species of beetles of the family Scarabaeidae as well as other groups of arthropods were screened for susceptibility to infection with S. lupi and G. ingluvicola. Arthropods were exposed to infective eggs of both parasites for a determined period of time and dissected/digested to determine the presence or absence of pre-infective and infective larvae. All the five species of dung beetles exposed to infection with S. lupi, namely, Pachylomerus femoralis, Scarabaeus rugosus, Gymnopleurus humanus, Kheper nigroaeneus and Anachalcos convexus were susceptible and, of the two species exposed to G. ingluvicola, only Gy. humanus was susceptible. Spirocerca lupi eggs developed in millipede species, Daratoagonus cristulatus, and remained as encysted larvae, while in Orthoporoides kyrhocephalus no development was observed. Spirocerca lupi larvae were not detected in the cricket species Gryllus assimilis, or the cockroach species Periplaneta americana, and, similarly, G. ingluvicola larvae were not detected in the millipede species O. kyrhocephalus. The difference in the susceptibility of the arthropods to the two parasite species may depend on their feeding biology.

Abstract:
This study documents dynamic changes in the mean abundance and body size of arthropods in an ephemeral pond over the course of a summer in order to understand the nature of interactions that shape this community, and to assess the risks posed by exposure to cercariae of the entomopathogenic digenean, Plagiorchis elegans, a potential control agent for larval mosquitoes. Chironomids were the most abundant, comprising almost two-thirds of all arthropods collected; they were followed by chaoborids, the most abundant predator. Other arthropods, in decreasing order of abundance, were the ephemerids, isopods, amphipods, odonates, dytiscids, and hemipterans. Infections were found only in chironomids and were extremely rare and of low intensity, conceivably due to predation of chaoborids on cercariae and may have protected the community from exposure to these parasites. Findings are discussed in terms of using entomopathogenic digeneans as agents in the biological control of mosquitoes.

Sexual parasites are intracellular symbionts capable of manipulating the reproduction of their hosts. They are widespread in Arthropods where they display a wide range of reproductive manipulations; these can be potentially involved in the evolution of mating systems, speciation, gene acquisition and sex determination. In particular, Wolbachia is thought to infect more than 66% of insect species and is also found in nematodes. However, little is known about the dynamics of Wolbachia infections at the community level. Although at the intra-population level, invasion dynamics have been extensively studied, the same is not true at the community level where the turnover of infections remains largely uncharacterised. The question of how often are new infections acquired through horizontal transfers between distantly related hosts remains also open. Moreover, as Wolbachia is seen as a good candidate for a transgenic vector against pests, understanding its dynamic at the community level is crucial. We proposed to address them by performing an exhaustive characterisation of sexual parasites in simplified systems, using the opportunity offered by small arthropod communities in isolated islands

Abstract:
Wolbachia est une bactérie Gram(-) intracellulaire modifiant la reproduction de nombreux arthropodes. Chez l'isopode Armadillidium vulgare, la souche wVulC entraîne la féminisation des mâles. Nous avons caractérisé deux opérons vir s'exprimant dans tous les tissus hôtes et codant un système de sécrétion de type IV (T4SS) pouvant permettre d'exporter des effecteurs bactériens vers le cytoplasme de l'hôte. La comparaison des séquences et de l'organisation des gènes de 37 souches de Wolbachia a révélé la forte conservation des deux opérons vir suggérant l'importance du T4SS dans la biologie de la bactérie. Nous avons également identifié, dans le génome en cours de séquençage de wVulC, 66 gènes codant des protéines à domaines ankyrines. Ces motifs forment des sites d'interactions protéine-protéine chez les eucaryotes et sont supposés être impliqués chez Wolbachia dans l'interaction avec des protéines de l'hôte. Nous avons montré qu'une des trois copies du gène pk2 de wVulC, n'est exprimée que chez des souches féminisantes mais chez aucune des 3 souches induisant l'incompatibilité cytoplasmique chez les isopodes terrestres. Ce produit du gène pk2 pourrait être impliqué dans la féminisation de l'hôte. Toutefois, nous avons réalisé des tests d'interaction par double-hybride en levures et par la méthode CRAfT (Cre-recombinase Reporter Assay for Translocation) entre les protéines du T4SS et cinq protéines à domaines ankyrines dont Pk2 afin de savoir si ces dernières étaient sécrétées par ce système. Les résultats montrent qu'aucun des cinq produits de gènes ank testés n'est sécrété par la bactérie mais se révèlent encourageants pour identifier les effecteurs de Wolbachia.

Abstract:
In Washington State the Pandemis leafroller, Pandemis pyrusana (Kerefoll) and obliquebanded leafroller, Choristoneura rosaceana (Harris) are serious pests in orchards in which mating disruption is used to control codling moth, Cydia pomenella. Resistance to organophosphate insecticides exacerbates the problem. Additionally, many question the dependence on insecticides and call for ecologically-based pest management. Parasitoid and predator conservation and augmentation via insecticide reduction and habitat manipulation are tactics proposed to achieve biological control. The objectives of these studies were to: 1) evaluate and compare development of leafroller populations and their biological control by parasitoids in an apple orchard with either a grass or alfalfa cover and in which no insecticides were used; 2) evaluate the influence of cover crops on the general orchard arthropod population in an orchard managed without insecticides; 3) evaluate the use of alfalfa as an orchard cover crop on fruit tree growth and development; and 4) conduct initial testing of strategies for augmenting the leafroller parasitoid Colpoclypeous florus. Experiments were conducted in an East Wenatchee, Washington apple orchard, over four years. Plots were approximately 0.5 ha in size and were sown to either grass cover or alfalfa. Insecticide applications were eliminated. In the absence of broad-spectrum insecticides leafroller populations initially rose to high levels and then dramatically declined. A granulovirus may have been primarily responsible for the decline. Leafroller parasitoids also contributed to leafroller biological control though not extensively. There were no differences in leafroller populations between ground cover treatments. In some instances parasitism was slightly greater in the alfalfa cover plots but this did not seem of any practical significance. Six species were identified in the parasitoid complex. No secondary arthropod pest achieved pest status in either ground cover during the study. Codling moth however became a serious problem in year four. Attempts to augment C. floras populations by seeding parasitized Ancylis comptana fragaria failed. Attempts to establish Xenotemna pallorana on the alfalfa cover to serve as an alternate host for C. floras were likewise unsuccessful. Alfalfa as a cover crop imposed no adverse effects on tree growth and development during the duration of these studies.
