Abstract:
SUMMARYThe effect of insect vectors on avian exposure to infection by pathogens remains poorly studied. Here, we used an insect repellent treatment to reduce the number of blood-sucking flying insects in blue tit Cyanistes caeruleus nests and examined its effect on nestling health status measured as body mass, nestling phytohaemagglutinin (PHA) response and blood parasite prevalence. We found that (i) the insect repellent treatment significantly reduced the number of blood-sucking flying insects in nests and (ii) the number of blood-sucking flying insects had a significant effect on the prevalence of the blood parasite Trypanosoma independently of the treatment. In addition, we found support for an adverse effect of parasite infections on nestling PHA response. Nestlings infected by Trypanosoma mounted a weaker response against PHA than non-parasitized ones. In addition, the number of blowflies in the nest was negatively associated with nestling PHA response. Overall, we found support for the hypothesis that blood-sucking flying insects attacking nestlings increase their exposure to parasite infections. Our results further substantiate the adverse effect of parasites on nestling condition.

Abstract:
It is probably a truism to say that what seems to be a single organism is, in fact, an assemblage of organisms – for there can hardly be an individual living outside a specialized laboratory that does not have commensals or parasites living within. The insects, the most diverse and numerous group of organisms on earth are no exception, and with micro- and macro-parasites from a wide range of taxa generate a remarkable range of interspecific associations. In some cases the insect is the sole host, in others it is an intermediate host or vector. It is the latter relationship which attracts much attention when insects and arachnids transmit infectious agents to humans, their animals or crops. Knowledge of the parasites of insects provides us with an opportunity to develop novel control methods for pests. Despite the diverse and widespread nature of insect infections, their impact on human well-being and the opportunity they give us to understand the complexity of the natural world, the subject remains a surprisingly neglected field. In this volume we endeavour to draw the veil from the 'black-box' approach to the insect stages of parasite life cycles to reveal some of the complexities of these relationships and how they are currently being analysed.

Abstract:
SUMMARYTrypanosoma rangeli is a protozoan parasite, which does not cause disease in humans, although it can produce different levels of pathogenicity to triatomines, their invertebrate hosts. We tested whether infection imposed a temperature-dependent cost on triatomine fitness using T. rangeli with different life histories. Parasites cultured only in liver infusion tryptose medium (cultured) and parasites exposed to cyclical passages through mice and triatomines (passaged) were used. We held infected insects at four temperatures between 21 and 30 °C and measured T. rangeli growth in vitro at the same temperatures in parallel. Overall, T. rangeli infection induced negative effects on insect fitness. In the case of cultured infection, parasite effects were temperature-dependent. Intermoult period, mortality rates and ecdysis success were affected in those insects exposed to lower temperatures (21 and 24 °C). For passaged-infected insects, the effects were independent of temperature, intermoult period being prolonged in all infected groups. Trypanosoma rangeli seem to be less tolerant to higher temperatures since cultured-infected insects showed a reduction in the infection rates and passaged-infected insects decreased the salivary gland infection rates in those insects submitted to 30 °C. In vitro growth of T. rangeli was consistent with these results.

Abstract:
Entomopathogenic nematodes (EPNs) in the generaHeterorhabditisandSteinernemaare lethal parasites of insects that are of interest as models for understanding parasite-host interactions and as biocontrol agents for insect pests. EPNs harbor a bacterial endosymbiont in their gut that assists in insect killing. EPNs are capable of infecting and killing a wide range of insects, yet how the nematodes and their bacterial endosymbionts interact with the insect immune system is poorly understood. Here, we develop a versatile model system for understanding the insect immune response to parasitic nematode infection that consists of seven species of EPNs as model parasites and five species ofDrosophilafruit flies as model hosts. We show that the EPNSteinernema carpocapsae, which is widely used for insect control, is capable of infecting and killingD. melanogasterlarvae.S. carpocapsaeis associated with the bacteriumXenorhabdus nematophila, and we show thatX. nematophilainduces expression of a subset of antimicrobial peptide genes and suppresses the melanization response to the nematode. We further show that EPNs vary in their virulence towardD. melanogasterand thatDrosophilaspecies vary in their susceptibilities to EPN infection. Differences in virulence among different EPN-host combinations result from differences in both rates of infection and rates of postinfection survival. Our results establish a powerful model system for understanding mechanisms of host-parasite interactions and the insect immune response to parasitic nematode infection.

Abstract:
Insect societies face many social parasites that exploit their altruistic behaviours or their resources. Due to the fitness costs these social parasites incur, hosts have evolved various behavioural, chemical, architectural and morphological defence traits. Similar to bacteria infecting multicellular hosts, social parasites have to successfully go through several steps to exploit their hosts. Here, we review how social insects try to interrupt this sequence of events. They can avoid parasite contact by choosing to nest in parasite-free locales or evade attacks by adapting their colony structure. Once social parasites attack, hosts attempt to detect them, which can be facilitated by adjustments in colony odour. If social parasites enter the nest, hosts can either aggressively defend their colony or take their young and flee. Nest structures are often shaped to prevent social parasite invasion or to safeguard host resources. Finally, if social parasites successfully establish themselves in host nests, hosts can rebel by killing the parasite brood or by reproducing in the parasites' presence. Hosts of social parasites can therefore develop multiple traits, leading to the evolution of complex defence portfolios of co-dependent traits. Social parasites can respond to these multi-level defences with counter-adaptations, potentially leading to geographical mosaics of coevolution. This article is part of the Theo Murphy meeting issue ‘Evolution of pathogen and parasite avoidance behaviours’.

Abstract:
Many parasites, including important species that affect humans and livestock, must survive the harsh environment of insect guts to complete their life-cycle. Hence, understanding how insects protect themselves against such parasites has immediate practical implications. Previously, such protection has been thought to consist mainly of mechanical structures and the action of lectins. However, recently it has become apparent that gut infections may interact with the host immune system in more complex ways. Here, using bumble bees, Bombus terrestris and their non-invasive gut trypanosome, Crithidia bombi, as a model system we investigated the effects of parasitic infection, host resources and the duration of infections on the host immune system. We found that infection doubled standing levels of immune defence in the haemolymph (the constitutive pro-phenoloxidase system), which is used as a first, general defence against parasites. However, physical separation of the parasite from the haemolymph suggests the presence of a messenger system between the gut and the genes that control the pro-phenoloxidase system. Surprisingly, we found no direct effect of host resource-stress or duration of the infection on the immune system. Our results suggest a novel and tactical response of insects to gut infections, demonstrating the complexity of such host–parasite systems.

Abstract:
Felled loblolly and slash pine trees were infested with Ips calligraphus (Germar) (80.2% of Ips population), I. avulsus (Eichhoff) (11.2%), and I. grandicollis (Eichhoff) (8.2%). A complex of beneficials associated with the Ips spp. broods consisted of 27 known or suspected insect predator species and 10 species of parasites. Predators comprised 98.8% and parasites 1.2% of the total beneficial insects collected. The predators Lonchaea sp. (Diptera: Lonchaeidae), Aulordum spp. (Coleoptera: Colydiidae), staphylinids and histerids (Coleoptera), and Scoloposcelis mississippensis (Drake and Harris) (Hemiptera: Anthocoridae) comprised 44.7, 6.8, 6.0, and 4.3%, respectively, of the total beneficial insect complex. The most abundant parasite was Roptrocerus eccoptogastri Ratzeburg, which accounted for 37.3% of all parasites but only 0.5% of the total beneficial insect complex. Abundance of both the beneficial insect complex and their Ips hosts was highest in trees felled in May and lowest in trees felled during August, suggesting a possible densitydependent relationship between the beneficials and the Ips spp. populations. Plegaderus sp. was the only species to show consistent preference for host tree, being more abundant in slash pine than on loblolly.

Abstract:
A família Trypanosomatidae compreende parasitas obrigatórios de vertebrados, plantas e invertebrados, as espécies exclusivas de insetos infectam principalmente dípteras e hemípteras. Nós revisamos a taxonomia de Herpetomonas e tripanossomatídeos de insetos que abrigam simbionte (SHT), comparando tripanossomatídeos da América do Sul e África. As filogenias revelaram duas novas espécies e possibilitou revalidar os gêneros Strigomonas e Angomonas. As análises filogenéticas revelaram três novas espécies de endossimbiontes proteobacteriano e apoiam a história evolutiva convergente entre hospedeiros e simbiontes. O DNA barcoding de 364 culturas de moscas identificaram 70 culturas (20%) como Angomonas, 71% deles de Calliphoridae. O gênero Herpetomonas compreende agora 13 espécies válidas, incluindo cinco novas espécies. Algumas espécies de Herpetomonas são parasitas generalistas de moscas e parecem ser tão cosmopolita como seus hospedeiros. Os taxon propostos podem ajudar a elaborar critérios mais eficientes para uma classificação melhor dos tripanossomatídeos.
Trypanosomatidae comprises obligate parasites of vertebrates, plants and invertebrates, the species exclusive of insects infect mostly dipterans and hemipterans. We revise the taxonomy of Herpetomonas and Symbiont Harboring Trypanosomatids (SHTs), by comparing trypanosomatids from South America and Africa. The phylogenies disclosed two new species and revalidated the genera Strigomonas and Angomonas. Phylogenetic analyses revealed 3 new species of proteobacterial endosymbionts and support a co-divergent host-symbiont evolutionary history. DNA barcoding of 364 cultures from flies identified 70 cultures (20%) as Angomonas, 71% of them from Calliphoridae. The recent dispersion of calliphorids was important in the dispersal of Angomonas worldwide. The genus Herpetomonas now comprises 13 valid species including 5 new species. Some species of Herpetomonas are generalist parasites of flies and appear to be as cosmopolitan as their hosts. The proposed taxa may help to elaborate more efficient criteria for a better classification of the Trypanosomatidae.

Abstract:
Providence virus (PrV) is a member of the Tetraviridae, a family of small, positive sense, single-stranded RNA viruses, which characteristically infect the midgut tissue of heliothine larvae. PrV is the only known tetravirus that replicates in cultured insect cells. The virus comprises a monopartite genome resembling members of the genus Betatetravirus with the capsid precursor protein undergoing autoproteolytic cleavage at its C-terminus consistent with other tetravirus capsid precursor proteins. Analysis of viral cDNA predicted the presence of three potential overlapping gene products (from 5` to 3`): (1) p130, a protein of unrecognized nucleotide or amino acid homology with a 2A-like processing site at its N-terminus; (2) p104, the replicase ORF, which was found to be phylogenetically related to tombus-and umbraviruses replicases. The presence of a read-through stop signal in the p104 ORF was proposed to produce and amino terminal product with a predicted MW of 40 kDa (p40) and (3) the capsid protein precursor (81 kDa) which has two 2A-like processing sites at its N-terminus. Metabolic radiolabelling of viral translation products in persistently infected MG8 cells and in vitro translation of the individual ORFs were performed in order to analyse the expression of PrV gene products. p130 was translated with no evidence of 2A-like processing. Two products of 40 kDa and 104 kDa were translated from the p104 ORF, indicating that the read-through stop signal was likely to be functional. Finally, the capsid protein precursor ORF produced a major translation product of 68 kDa corresponding to the capsid protein precursor as well a peptide of 15 kDa that was attributed to the activity of the second 2A-like site at the N-terminus of the p81 ORF. The subcellular distribution of viral RNA (vRNA) and p40 in MG8 cells was investigated using immunofluorescence and biochemical fractionation. The results showed that p40/p104 and vRNA accumulated in polarized, punctate structures in some but not all MG8 cells and in some cases, co-localization was observed. This thesis concludes that PrV is a novel tetravirus with significant similarities plant carmolike viruses that should be re-classified at the family level.

Abstract:

Abstrakt: Jag har undersökt hur älvreglering påverkar mängden knott (Tvåvingar: Simuliidae) längs flera norrlandsälvar och vilka konsekvenser denna påverkan får för den landlevande fågelfaunan. Studien visar att utbyggnad av älvar har en negativ effekt på mängden knott. Det fanns sju gånger högre tätheter av knott längs "orörda älvar" jämfört med utbyggda älvar.

Skillnaden i antal knott mellan älvtyperna var mycket större för knotthanar än för knotthonor, vilket förklaras av att honorna är rörligare eftersom de flyger och letar efter blod. Knott lever av blod från ett flertal däggdjur och fåglar och visar en stor variation i värd-specificitet mellan olika arter. Jag fann en högre frekvens av haemosporida blod parasiter (Leucocytozoon) i fåglar längs "orörda" Vindelälven jämfört med den reglerade Umeälven. Detta mönster stämmer väl överens med tätheten fågelparasiterande knott som är lägre längs Umeälven. Knott attackerade främst värdar som var stora och vanliga. Fågelsamhällets sammansättning skiljde sig mellan orörda och utbyggda älvdalar. Tätheten av icke insektsätande fåglar tenderade att minska, efter häcksäsongen, längs orörda älvar medan den ökade längs utbyggda älvar. Den insektsätande fågeln svartvit flugsnappare (Ficedula hypoleuca Pallas) uppvisade större häckningsframgång längs orörda älvar jämfört med utbyggda älvar. Detta är förmodligen en effekt av den större mängden insekter som finns längs orörda älvar.


The effects of river regulation on blackfly (Diptera: Simuliidae) abundances and consequences for the avifauna in terrestrial environments were studied along multiple rivers in northern Sweden. I found that impoundment of rivers has detrimental effect to blackfly abundances. The densities of large-river breeding blackfly species were several-fold higher along free-flowing than along regulated rivers. The difference in abundances was much larger in males than blood-seeking females. Blackflies attacked a variety of mammalian and avian hosts and showed different levels of host-specificity between species. I found higher prevalence of haemosporidian blood parasites (Leucocytozoon) in birds along the free-flowing Vindel River in comparison to the regulated Ume River, where the lower densities of ornithophilic blackflies were reduced. Blood-seeking blackflies predominantly attacked large and/abundant hosts.

Assemblages of birds differed between valleys of regulated and free-flowing rivers. Densities of noninsectivorous birds tended to decrease along free-flowing rivers in the post-breeding season, but increased along regulated rivers at the same time. Insectivorous European pied flycatcher (Ficedula hypoleuca Pallas) showed greater fledging success along free-flowing than regulated rivers, which probably reflects the higher insect abundances found along freeflowing rivers.

Abstract:
Canola, Brassics napus L. is a relatively new crop in South Africa. Insect pests have not yet been a major problem, but the notorious brassica specialist, diamondback moth (DBM), Plutella xylostella (L.) (Plutellidae) is establishing itself as a serious pest of this crop. DBM is the most important insect pest of plants from the family Brassicaceae throughout the world. It has developed resistance to all chemical pesticides used against it in the field and to toxins of the bacterium Bacillus thuringiensis. The pest status of DBM in South Africa is lower than in other countries with similar climates. However, due to indiscriminate use of pesticides, local populations of DBM are showing signs of resistance. An initial survey has indicated that in addition to DBM, canola is also attacked by aphids, Myzus persicae (Sulzer), Brevicoryne brassicae (L.), Lipaphis e1ysimi (Kaltenbach), (Aphiade), thrips, Thrips tabaci (Lindeman) and other pests mostly brassica specialists. The study was initiated to determine the composition of the community of insects found on canola, the seasonal phenology of DBM populations in canola, and the composition, relative abundance and seasonality of its parasitoids. Monitoring of the insects was carried out at weekly intervals for three years at Rietondale and Bapsfontein in Gauteng province of South Africa. Berlese funnels have been found to be useful in extracting insects from plants, and were used to indicate the presence ofDBM larvae and other insects found on canola. Adults of DBM were monitored with synthetic pheromone traps; larval and pupal populations were monitored by scouting canola plants. Samples of larvae, pupae and parasitoid cocoons were brought into the laboratory. Parasitoids that emerged were identified and their incidence recorded. Monolepta cf bifasciata (Chrysomelidae) and Listroderes costrirostris (Schoener) (Curculionidae) were the most abundant of the coleopteran pests. (DBM) and Heliothis armigera (H.) (Noctuidae) were most abundant lepidopteran pests of Canola. There was a high proportion of first and second instar larvae as indicated by the results of the Berlese funnels as compared to visual scouting in Bapsfontein. From May to August the infestation level of DBM was high, reaching the maximum of 0.25 larvae per plant in June 1996, then declined and remained low for the rest of the season in Rietondale. From September to December for all three years of the study, the population levels Of DBM were high, reaching a maximum of 9.6larvae per plant in September 1997, and remained low from January to August in Bapsfontein. The number of adult moths per trap per week ranged from 0 to 91 in Rietondale, peaking in January 1996 and September 1997. There was no correlation between infestation levels and the pheromone trap catches. In contrast to Rietondale, there was a high correlation between pheromone trap catches and subsequent larval infestations at Bapsfontein. Although DBM infestation levels were generally low, parasitism levels often reached 100% caused by a complex of parasitoids. During the period of study, the following hymenopteran parasitoids were recorded: Cotesia plutellae (Kurdjumov) and Apanteles eriophyes (Nixon), Braconidae), both larval parasitoids, Diadegma mollipla (Holmgren) (Ichneumonidae), and Oomyzus sokolowskii (Kurdjumov) (Eulophidae), larval-pupal parasitoids, Diadromus collaris (Gravenhorst) (Ichneumonidae) pupal parasitoid, and the hyperparasitoids Mesochorus sp. (Ichneumonidae) and Pteromalus sp. (Pteromalidae). Cotesia plutellae was the most abundant parasitoid occurring throughout the year..

Abstract:
Introdução: A Leishmaniose tegumentar é uma doença parasitária, crônica e infecciosa, sendo uma das principais doenças negligenciadas. É caracterizada pela infecção ativa do protozoário do gênero Leishmania, caracterizada pelo desenvolvimento de lesões cutâneas, que podem produzir úlceras e deixar cicatrizes, gerando danos físicos e emocionais nos indivíduos infectados. Por sua fácil transmissão, que se dá através de insetos hematófagos, flebotomíneos, é importante o estudo das formas de ação do parasita no organismo humano, visando-se formas de tratamento mais eficientes, já que a doença atinge muitos indivíduos nas regiões endêmicas e não existem muitas alternativas para o tratamento. Objetivo: Analisar a infecção do parasita do gênero Leishmania no organismo e sua respectiva ação no sistema imune. Metodologia: Realizou-se uma pesquisa bibliográfica nas bases de dados científicos Scielo, PubMed, LILACS e Google Acadêmico, considerou-se publicações de artigos científicos dos últimos cinco anos. Resultados e discussão: O ciclo evolutivo da Leishmania apresenta duas formas: promastigota, encontrada no vetor, e amastigota, forma intracelular presente nos hospedeiros. Os glicanos, polissacarídeos, possuem importante papel durante o processo infeccioso, os glicoconjugados como glicoinositolfosfolipídios e proteofosfoglicanos tipo mucina estão envolvidos nas primeiras linhas de infecção por macrófagos. Já as glicoproteínas ancoradas por sitol exercem funções essenciais na interação parasita-hospedeiro. A metaloprotease modula uma ampla via de sinalização das células hospedeiras, facilita o escape do parasita da lise e inibe a resposta das células Natural Killers, protegendo os parasitas intracelulares. Outros fatores importantes no processo infeccioso são a proteína PSA-2, envolvida na ligação e invasão dos parasitas em macrófagos e o ácido siálico, utilizados pela Leishmania para estabelecer ligações com os receptores da membrana, presentes nas células hematopoiéticas, promovendo sua entrada nos macrófagos. Conclusão: A compreensão destas interações entre parasita e hospedeiro durante e após o processo infeccioso é importante para ter uma visão de como os protozoários implementam a infecção no organismo e burlam a resposta imune do hospedeiro. Desta forma, novos medicamentos que sejam direcionados a estes fatores, seriam fundamentais para a melhoria da eficácia, segurança do tratamento e diminuição dos riscos de resistência aos medicamentos, com a redução dos riscos de consequências nocivas advindas desta enfermidade.

Abstract:
A positive role in the spread of viruses on the leaves can be played by parasitic and predatory insects, which come in contact with dead larvae, take over the polyhedra on their bodies and spread them in the host's biotope. Phytophagous insects were used for research: Mamestra brassicae and Heliothis armigera. As an experimental material served biological baculoviral preparations based on the genus Baculoviridae family that differ from other biological preparations, have an epizootic character and transmit the pathogen vertically and horizontally in decreasing populations of harmful insects from one generation to another through their selectivity.

Abstract:
Myiasis is a parasitic infestation, rarely seen in the vulval region with more cases being reported in tropical, subtropical and warm temperate climate. Cutaneous myiasis can be misdiagnosed as cellulitis, leishmaniasis, sebaceous cysts, staphylococcal boil, insect bite or skin abscess. Knowledge of the characteristic clinical findings and the close inspection of skin lesions are key to diagnosing myiasis. We report a case of vulval maggots which was misdiagnosed as vulvar carcinoma and caused undue anxiety to the patient.
