Characterization of the internal reproductive organs and their state as diapause indicator in Phytalus sanctipauli Blanchard, 1850 (Coleoptera, Scarabaeidae) BJB
DIEFENBACH,LÚCIA M. GUEDES; REDAELLI,LUIZA RODRIGUES; GASSEN,DIRCEU NERI.
The internal reproductive organs of females and males of Phytalus sanctipauli are described and illustrated. The amount of fat body in the abdominal cavity was assessed. The remaining in the soil, from March to September, of sexually immature females and males bearing the abdominal cavity totally filled with fat body characterized the state of diapause in this species, in Coxilha (52°20'W and 28°05'S), RS, Brazil.

De novo transcriptome assembly of the lobster cockroach Nauphoeta cinerea (Blaberidae) Genet. Mol. Biol.
Segatto,Ana Lúcia Anversa; Diesel,José Francisco; Loreto,Elgion Lucio Silva; da Rocha,João Batista Teixeira.
Abstract The use of Drosophila as a scientific model is well established, but the use of cockroaches as experimental organisms has been increasing, mainly in toxicology research. Nauphoeta cinerea is one of the species that has been studied, and among its advantages is its easy laboratory maintenance. However, a limited amount of genetic data about N. cinerea is available, impeding gene identification and expression analyses, genetic manipulation, and a deeper understanding of its functional biology. Here we describe the N. cinerea fat body and head transcriptome, in order to provide a database of genetic sequences to better understand the metabolic role of these tissues, and describe detoxification and stress response genes. After removing low-quality...

Effect of ivermectin on the life cycle and larval fat body of Culex quinquefasciatus BABT
Alves,Stenio Nunes; Serrão,José Eduardo; Mocelin,Giovani; Melo,Alan Lane de.
The present work investigated the behavior, survival rate and lethal effect of 1.5 ppb ivermectin on Culex quinquefasciatus larvae, based on morphological and biological parameters, and possible alterations of their fat body. Changes in the number of eggs/egg mass and length of the larval stage were investigated. For this experiment, 600 larvae of 3rd and 4th instars of the mosquito were tested. The laid eggs were separated and the hatched larvae were counted. Some larvae submitted to 1.5 ppb ivermectin solution were used to prepare samples for histological study. Results obtained showed that ivermectin in a concentration of 1.5 ppb caused paralysis to the larvae with a mortality rate of 73.38%, mobilization of substances stored in the fat body and...

Fat body morphology of Eriopis connexa (coleoptera, coccinelidae) in function of two alimentary sources BABT
Sarmento,Renato de Almeida; Oliveira,Hamilton Gomes de; Holtz,Anderson Mathias; Silva,Solange Marques da; Serrão,José Eduardo; Pallini,Ângelo.
This work investigated the influence of two alimentary sources: aphids and mites, in the morphology of the fat body of E. connexa. Results showed that fat body cells of individuals fed with aphids presented areas more than three folds higher (511 ± 98,7µm²) than those of beetles fed with mites (162 ± 34,9µm²). Histochemical tests showed that nutrient amount stored in fat body was higher in lady-beetles fed on aphids.

Insights into the Melipona scutellaris (Hymenoptera, Apidae, Meliponini) fat body transcriptome Genet. Mol. Biol.
Sousa,Cristina Soares de; Serrão,José Eduardo; Bonetti,Ana Maria; Amaral,Isabel Marques Rodrigues; Kerr,Warwick Estevam; Maranhão,Andréa Queiroz; Ueira-Vieira,Carlos.
The insect fat body is a multifunctional organ analogous to the vertebrate liver. The fat body is involved in the metabolism of juvenile hormone, regulation of environmental stress, production of immunity regulator-like proteins in cells and protein storage. However, very little is known about the molecular mechanisms involved in fat body physiology in stingless bees. In this study, we analyzed the transcriptome of the fat body from the stingless bee Melipona scutellaris. In silico analysis of a set of cDNA library sequences yielded 1728 expressed sequence tags (ESTs) and 997 high-quality sequences that were assembled into 29 contigs and 117 singlets. The BLAST X tool showed that 86% of the ESTs shared similarity with Apis mellifera (honeybee) genes. The...

Protein content and electrophoretic profile of fat body and ovary extracts from workers of Melipona quadrifasciata anthidioides (Hymenoptera, Meliponini) Iheringia, Sér. Zool.
Oliveira,Vagner T. Paes de; Cruz-Landim,Carminda da.
Workers of Melipona quadrifasciata anthidioides (Lepeletier, 1836) develop their ovaries and lay eggs, therefore the production of vitellogenin is expected. In electrophoretic profiles only fat body extracts from nurse workers and ovary extracts from newly-emerged workers show protein with molecular mass similar to vitellogenin. However, an increase in the protein content was detected in forager fat body. This increase was attributed to storage of vitellogenin or other proteins in the previous phase and not discharged into the hemolymph or to an effect of the increased titre of juvenile hormone in this phase of worker life over the fat body functioning.
