| The root-knot nematode Meloidogyne javanica (Treub, 1885) Chitwood, 1949, was identified in roots, nodules and shells of peanut plants (Arachis hypogaea L.), cv. Florman-INTA, collected from a field in Menno colony, Chaco Central region of Paraguay. Infected plants were observed in patches, showing wilting and drying of vegetative parts. Peanut had been grown ininterruptly for many years in the same area and patches had already been observed in the preceding year in cv. Starr. Nematodes collected from roots in this field reproduced on tomato cultivar rutgers and peanut cultivar florunner and produced egg-masses on roots, nodules and shells of cultivar Florman. This is the first report on M. javanica parasiting peanut in Paraguay. |

| Thyrinteina arnobia, is one of the most important defoliating caterpillars of Eucalyptus in Brazil The objective of this work was to evaluate the development and the reproduction of feeding on leaves of guava (Psidium guajava) or Eucalyptus grandis in the 15th generation, after rearing this species for 14 genrations on guava leaves. T. arnobia showed shorter larval period, better viability of caterpillars and pupae, heavier pupae, higher number of eggs per female, better egg viability and shorter longevity of females in guava leaves than in Eucalyptus leaves. The better development and reproduction with P. guajava showed that this insect could be reared in laboratory with guava leaves. |

| Aleiodes Wesmael is the most diverse rogadine genus, with koinobiont endoparasitic development in Lepidoptera caterpillars resulting in mummification of the host remains. Aleiodes japi sp. nov. is described and illustrated. Type specimens of the new species were reared from Physocleora grosica and Ischnopteris sp. (Lepidoptera, Geometridae, Ennominae) larvae. Host larvae were collected on Alchornea triplinervia (Euphorbiaceae) at the Reserva Biológica Municipal da Serra do Japi, Jundiaí, São Paulo, Brazil. This is the second species of circumscriptus/gastritror group described from Brazil. |

| Biomphalaria glabrata is a freshwater Planorbidae snail. In its environment, this mollusk faces numerous microorganisms or pathogens, and has developed sophisticated innate immune mechanisms to survive. The mechanisms of recognition are quite well understood in Biomphalaria glabrata, but immune effectors have been seldom described. In this study, we analyzed a new family of potential immune effectors and characterized five new genes that were named Glabralysins. The five Glabralysin genes showed different genomic structures and the high degree of amino acid identity between the Glabralysins, and the presence of the conserved ETX/MTX2 domain, support the hypothesis that they are pore-forming toxins. In addition, tertiary structure prediction confirms that... |

| Several species of crabs from hydrothermal vent sites in the Pacific Ocean Were found to be infested by small, symbiotic nemertean worms. Worms occurred on both male and female crabs, and were located in mucous sheaths adhering to the axillae between the limbs of males and females, the setae of the pleopods of females, and the sterna of infested male and female crabs. Only juvenile and regressed adult worms were observed, primarily because no ovigerous hosts were examined. Similar species of worms mature by eating eggs, then regress or die after host eclosion. Based on the size of the worms from file vent crabs, their habitus with their crustacean hosts, the presence of accessory stylet pouches, and the presence of a single stylet on a large basis... |

| The calyptoblast hydroids Aglaophenia struthionides (Murray, 1860), Eucopella (= Campanularia) everta (Clark, 1896), and Abietinaria spp. in the low intertidal zone at Mussel Point, Pacific Grove, Monterey Bay, California, often bear the adult pycnogonids Tanystylum duospinum Hilton, 1939 and Ammothea hilgendorfi (Böhm, 1879). Larval stages of these pycnogonids were found living and feeding on Eucopella everta. The larvae of Tanystylum duospinum are ectoparasitic. Those of Ammothea hilgendorfi are endoparasitic in the gastrovascular cavities of hydranths. Larvae of both species feed on the gut contents of Eucopella everta, often on the same hydroid colony. |

| Fruits were collected over a 12-year period to determine the host status for the Carambola fruit fly, Bactrocera carambolae Drew & Hancock, and other tephritid species in Suriname, South America. Over 11,000 fruit samples were collected from many locations and the total of 20 fruit species were recorded as host, ranging in infestation from heavy to occasional. Over 650 samples of 188 fruit species, including many wild species, were collected and no fruit flies were reared. This work, which started specifically to obtain information on the Carambola fruit fly, resulted also in detailed information regarding the importance, distribution and host preferences of several Anastrepha species, and the status of fruit fly parasitoids. |

| The genus Stylogaster Macquart (Diptera, Conopidae) is represented by 14 species in the Afrotropical region, five of them endemic to Madagascar and two recorded from South Africa, one of them endemic. Fifteen specimens of Muscidae, 14 from Madagascar and one from South Africa, belonging to 10 species, impaled with Stylogaster eggs were examined. Among them, three new muscid host species were found. The dissected eggs were all similar, suggesting the presence of the same species in both localities, what is not recorded until now. The available data on the dipteran Stylogaster eggs hosts in Africa is summarized. Color photos of the material examined are presented. |

| ABSTRACT During the present study, the host-parasite relationship between mosquitoes and parasitic mites was investigated. The 8954 individuals of male and female mosquitoes belonging to 26 genera: seven each of Aedes and Culex, six of Anopheles and one each of Toxorhynchites, Coquillettidia and Uranotaenia were collected from 200 sites. The male and female mosquitoes were collected from the State of Uttar Pradesh, located at 26.8500° N, 80.9100° E in North India by deploying Carbon dioxide-baited and gravid traps. The intensity of mite's infection, type and number of mites attached to mosquitoes, mite's preference for body parts and host sexes were the parameters used to determine host-parasite relationship. Eight species of mites: Arrenurus acuminatus,... |
