| The coral-eating barnacle Hoekia monticulariae (Gray, 1831), the only internal parasite among the Thoracica described to this day, is characterized by an irregularly-shaped shell nestled cryptically between the polyps of the hermatypic coral Hydnophora Fischer, 1807, which occurs throughout most of the Indo-West Pacific. Because of its protean form, cirripedologists have failed to appreciate the diversity of taxa related to Hoekia, , a presumed monotypic genus. We describe seven new species divided between Hoekia and three new genera, Eohoekia, Parahoekia, and Ahoekia for which the Tribe Hoekiini is proposed. As in other pyrgomatids, calcareous overgrowth by the coral is inhibited around the edge of the wall and aperture. But in Hoekiini a pseudopolyp,... |

| BACKGROUND: Biotic processes, such as predation and parasitism events, are crucial for answering questions in ecology and evolution. Here, we report predation and ectoparasitism events of invertebrates upon tadpoles in aquatic habitats of southern Brazil. FINDINGS: Four lentic water bodies were sampled twice a month (December 2012 to March 2013). Those water bodies were located in the Diamante do Norte County, State of Paraná, southern Brazil. The tadpoles, Dendropsophus aff. minutus, Hypsiboas raniceps, Scinax fuscovarius, Physalaemus cuvieri and Elachistocleis bicolor were observed being predated by six different invertebrate predators. However, Leptodactylus fuscus and Pseudis sp. were also recorded on the same water bodies and were not observed being... |

| ABSTRACT Amblyomma Koch, 1844 is distributed worldwide, with ca. 130 species currently recognized. These ticks are vectors of pathogens to animals and humans, including the causative agent of the New World Rocky Mountain spotted fever. Species of the Amblyomma parasitize a wide range of organisms, especially medium and large terrestrial mammals. Here we report for the first time the association of Myotis lavali Moratelli, Peracchi, Dias & Oliveira, 2011, Noctilio albiventris Desmarest, 1818 and Noctilio leporinus (Linnaeus, 1758) as hosts for Amblyomma sculptum Berlese, 1888. The ticks were originally identified as Amblyomma cajennense (Fabricius, 1787), in 2011. However, a later taxonomic review indicated that the species of the A. cajennense complex... |

| Mass rearing of parasitoids is a fundamental step for biological control programs. The biological characteristics of Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae) were evaluated in pupae of Anticarsia gemmatalis Hubner (Lepidoptera: Noctuidae) stored at low temperatures. Twenty four hours-old pupae of A. gemmatalis were stored at 12 °C for 0, 1, 3, 6, 9, and 12 d and then exposed to parasitism by P. elaeisis females. The life span of P. elaeisis was affected and ranged from 19 to 24 d on the pupae of the host. Parasitism reached 100% of the host pupae after storage in all periods at 12 °C, and adults emerged from 20.00 to 54.54% of them. The progeny of P. elaeisis ranged from 71 to 198 and had an inverse relationship with the... |

| The genus Diadegma have some species able to parasite Plutella xylostella (L.) (DBM). Laboratory studies were carried out on a Diadegma sp. from Reunion Island to elucidate its ability to parasite DBM larvae, and to determine the influence of the temperature on its fecundity, longevity, oviposition and the consumption of cabbage leaves by parasitized DBM larvae. Parasitism rates were close to 70% for the L2 and L3 instar, and 53% for the L4. At 15°C, there were no progeny. At 20°C and 25°C, the percentage of parasitism was near 70%. At 29°C, the percentage parasitism was similar but the number of males produced was higher. Parasitized DBM larvae consumed 35% less leaf surface than non parasitized larvae. This Diadegma sp. is a possible candidate for... |

| Cyrtomon luridus (Boh.), a native insect of wild Solanaceae, has adapted to the medicinal plant Duboisia sp., introduced from Australia, causing damages up to 100% mortality. Microctonus sp. is the most important natural enemy of C. luridus and its potential for biological control was investigated in this work. This study was carried out in Arapongas, Paraná State, Brazil, from 1994 to 1996. Parasitism of C. luridus by Microctonus sp. was highest from February through June (maximum of 54% in May 1996), when the C. luridus adult population was decreasing. The female sex ratio of Microctonus sp. under natural conditions was 0.57 to 0.69, which was close to 1 male : 2 female. Production of males occurs parthenogetically (arrhenotoky). In the laboratory,... |

| Relata-se o primeiro caso de infecção de perus, Meleagris gallopavo, por Cheilospirura hamulosa no Brasil, com base no achado de três espécimes fêmeas de C. hamulosa, inseridos na submucosa da moela de um peru, retirado de um lote de 15 aves, provenientes de criadouros domésticos no estado de Minas Gerais. A ocorrência foi de 6,7%. A ave parasitada não apresentava sinais clínicos. As lesões microscópicas da moela eram severas, caracterizando-se por intensos processos inflamatórios crônicos e difusos, com infiltrados mistos de granulócitos, estendendo-se à mucosa e às camadas musculares. Nessa área, foram observados fragmentos dos parasitos e perfuração da mucosa, com destruição das camadas musculares. |

| Parasites of adult bees are almost exclusively flies and the most important of them are conopids. This note registers for the first time the association of species of Physocephala (Diptera: Conopidae) with Centris (Heterocentris) analis (Fabricius). From 26 females and nine males of the host species found dead inside trap-nests on the campus of the University of São Paulo, Ribeirão Preto, Brazil, 35 parasitoids were obtained belonging to nine species of Physocephala. The data show that C. analis is a host to several conopid flies, and suggest that such parasitoids can play an important role in population control of this bee species. |

| This work aimed to evaluate the Deladenus siricidicola, Bedding (Neotylenchidae)parasitism in adults Sirex noctilio, Fabricius, 1793 (Hymenoptera: Siricidae). Timber was sampled by cutting out pieces of 0.80 m in length in Sirex noctilio attacked and Deladenus siricidicola inoculated Pinus taeda. Longs were 15-20 cm in diameter, according to the tree age. Samples were packed in gauze-cages, for daily observations, till S. noctilio adults emergence. The emerged insects were transported, in plastic containers to the laboratory, where they were sectioned and dissected under stereoscopic microscopy to observ the nematode occurrence. From the initially proposed ten units, nine of them were evaluated in a total of 1,810 emerged adult insects, being 1,441 males... |

| The Neotropical brown stink bug, Euschistus heros (Fabr.), was collected on sunflower [Helianthus annuus (L.)], soybean [Glycine max (L.) Merrill], star bristle [Acanthospermum hispidum (DC.)], and under fallen leaves of mango tree [Mangifera indica (L.)] and privet (Ligustrum lucidum Ait.), during one year, to evaluate the diapause incidence and the occurrence of different seasonal morphs. The majority of the insects (ca. 90%) with mature reproductive organs was observed during the summer (December-March), when E. heros was found on soybean or on sunflower; in the beginning of autumn, most insects (87%) showed immature reproductive organs, and they were found on star bristle and under fallen leaves. Bugs with mature reproductive organs had more developed... |

| ABSTRACT Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative releases in irrigated coffee plantations in semiarid regions of Brazil are under consideration and dispersal capacity of D. longicaudata in this habitat are important to develop release strategies. Approximately 2,000 individuals of D. longicaudata (5 to 7 days old) were released in the center of a fruiting coffee plantation every two weeks from Dec. 2009 to Apr. 2010. Dispersal from the central release point was monitored to the north, south, east, west, northeast, northwest, southeast and southwest at 11 distances, beginning at 4.6... |

| From September 2001 through September 2002, house fly and stable fly pupae were collected weekly from three fly habitats at the University of Florida Research dairy in northcentral Florida and evaluated for parasitism. Varying parasitism percentages were observed throughout the study but they were not affected by temperature, precipitation or fly abundance. Of the 6,222 house fly pupae and 1,660 stable fly pupae that produced either a host fly or a parasitoid, 26.9% and 26.7% were parasitized, respectively. Ten parasitoid species were recovered, with the genus Spalangia accounting for 85.7% of the total; the most common parasitoids attacking house fly and stable fly pupae were Spalangia endius Walker (33.9% and 27.3%), S. cameroni Perkins (27.9% and... |

| We studied the spatial heterogeneity of infection of the marine bivalve Cerastoderma edule (cockle) by trematode parasites at 5 different scales in Banc d'Arguin, France. At the km-scale, the communities of trematodes differed among stations in terms of species composition and specific abundance. Infection heterogeneity was likely due to the occurrence of the definitive host and the conditions of transmission (water parameters). At the 100 m scale, trematode species richness was similar among stations, but specific trematode abundances differed. The most significant variable in terms of explaining trematode infection heterogeneity was the presence of the first intermediate host. At the 10 m scale, the distance at which parasite abundance diminished varied... |
