25. Are the dinosauromorph femora from the Upper Triassic of Hayden Quarry (New Mexico) three stages in a growth series of a single taxon?
ABSTRACT The lagerpetid Dromomeron romeri and the theropod Tawa hallae are two dinosauromorphs from the Norian (Upper Triassic) of the Chinle Formation, situated in New Mexico, USA. However, a recent study suggests the inclusion of the holotype of D. romeri (GR 218) and paratype (GR 155) and referred (GR 235) specimens of T. hallae in an ontogenetic series o

26. Temporal progress and spatial patterns of quiescent diseases in guava influenced by sanitation practices
ABSTRACT: Postharvest diseases are a major problem in guava crops as the symptoms normally appear during fruit ripening. This study aimed to detect and characterize the temporal dynamics and spatial patterns of the most important guava diseases in orchards with and without removal of crop residues as a sanitation practice. The experiment was conducted in an

27. Immature stages of Temenis laothoe meridionalis Ebert (Lepidoptera, Nymphalidae, Biblidinae)
ABSTRACT The external morphology and life cycle of the immature stages of Temenis laothoe meridionalis Hübner, [1819] (Lepidoptera, Nymphalidae, Biblidinae), associated with Serjania laruotteana (Sapindaceae) in Curitiba, Paraná, Brazil, are described and illustrated with photographs and images from scanning electron microscopy. Special aspects of the exte

28. A new species of Leurocephala Davis & Mc Kay (Lepidoptera, Gracillariidae) from the Azapa Valley, northern Chilean Atacama Desert, with notes on life-history
ABSTRACT The Neotropical micromoth genus Leurocephala Davis & Mc Kay, 2011 (Lepidoptera, Gracillariidae) was originally described to include only the type species, L. schinusae Davis & Mc Kay, 2011, whose leaf miner larvae are associated with Anacardiaceae in Argentina, Brazil and Paraguay. An integrative analysis including morphology, life history and DNA b

29. Morphology of immature stages and mating behavior in Liogenys fusca (Blanchard) (Coleoptera, Melolonthidae, Melolonthinae)
ABSTRACT Liogenys fusca is a rizophagous insect pest in various crops of economic importance in Brazil. Here we investigated the morphology of immature stages and mating behavior of this species. The redescription of the 3rd instar larvae of L. fusca in this work allows identification and registration of occurrence independently of adults, which occur sporad

30. First high-altitude record of Bucculatrix mirnae Vargas and Moreira (Lepidoptera, Bucculatricidae) on a newly documented host plant: the importance of host plant distribution for conservation on the western slopes of the Andes mountains of northern Chile
ABSTRACT Bucculatrix mirnae Vargas and Moreira, 2012 (Lepidoptera, Bucculatricidae) is a micromoth native to the coastal valleys of the Atacama Desert previously known to occur only in the type locality of the Azapa Valley, close to sea level. Its immature stages are associated with the shrub Baccharis salicifolia (Ruiz & Pav.) Pers. (Asteraceae). We report

31. Gonadal development and fecundity of the smooth weakfish Cynoscion leiarchus (Teleostei: Perciformes: Sciaenidae) in a tropical Brazilian bay
ABSTRACT Cynoscion leiarchus (Cuvier, 1830) is a coastal fish species that is widely distributed along the Western Atlantic coast, from Belize to Southern Brazil. In Brazil, C. leiarchus It is an important resource for commercial and artisanal fisheries. Our objective was to describe the oogenesis and spermatogenesis stages of the species and to estimate bat

32. A key and checklist to the Neotropical forensically important "Little House Flies" (Diptera: Fanniidae)
ABSTRACT Fanniidae (Insecta: Diptera) is a relatively small family (ca. 350 spp.) with five genera, of which Fannia Robineau-Desvoidy, 1830 and Euryomma Stein, 1899 have Neotropical distributions. Some of these species are almost always found in forensic studies. Forensically relevant species have been neglected, despite recent forensic studies that suggest

33. Immature stages of Spodoptera cosmioides (Lepidoptera: Noctuidae): developmental parameters and host plants
ABSTRACT The goal of this study was to detail the temporal and morphological parameters of the immature stages of Spodoptera cosmioides (Walker, 1858) and to gather information about their larval host plants. Larvae were reared on artificial diet and under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase). The viability of eggs, larvae

34. Association of Anagrus amazonensis Triapitsyn, Querino & Feitosa (Hymenoptera, Mymaridae) with aquatic insects in upland streams and floodplain lakes in central Amazonia, Brazil
ABSTRACT Anagrus amazonensis Triapitsyn, Querino & Feitosa (Hymenoptera, Mymaridae) is a parasitoid that uses aquatic insect eggs as a host for the development of its immature stages. The objectives of this study are to record the interaction between A. amazonensis and its hosts and the aquatic plants used by these hosts to lay their eggs. Field work was con

35. Redescription of immature stages and adults of Nilio (Nilio ) brunneus (Coleoptera: Tenebrionidae: Nilioninae)
ABSTRACT We described immature stages of Nilio (Nilio ) brunneus Thomson, 1860 and provide a supplementary description for adults, including new data on the anatomy of the female and male terminalia. We observed N. brunneus feeding on the lichen Parmotrema sp., and that immature and adult are gregarious, with sessile pupae and generations overlapping. In lab

36. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w
