1. Compared activity of agonist molecules towards ecdysone receptor in insect cell-based screening system
RESUMO: O receptor de ecdisona, naturalmente ativado por hormônios esteroidais, é uma proteína-chave nos processos de muda e reprodução de insetos. A ativação artificial desse receptor por meio de pesticidas específicos induz um processo de ecdise anômala, levando o inseto à morte por dessecação e inanição. Neste trabalho, foi estabelecido um p

2. Exploring the Insecticide and Acaricide Potential of Development Regulators obtained from Restinga vegetation from Brazil
Abstract: As a part of our continuing search for insect and arthropod development regulators from Brazilian restinga vegetation of the Rio de Janeiro State, crude extracts, purified fractions and essential oils were submitted to screening tests seeking for biological activities on the development of the insects Rhodnius prolixus, Dysdercus peruvianus, Oncope

3. Comparative morphometric evaluation of hepatic hemosiderosis in wild Magellanic penguins (Spheniscus magellanicus) infected with different Plasmodium spp. subgenera
Resumo Malária aviária é uma das mais relevantes doenças em pinguins cativos. Foram aplicadas técnicas morfométricas para avaliar a hemossiderose hepática em pinguins-de-Magalhães (Spheniscus magellanicus ) de vida livre em reabilitação negativos (n = 9) e naturalmente infectados por diferentes subgêneros de Plasmodium spp. (n = 24), quanto a: su

4. Modulation of Physiologic Parameters in Molted Isa Brown Laying-Hens by Glutamine + Glutamic Acid Supplementation
ABSTRACT Feed costs are the main limiting factors in poultry industry and alternative sources of food and/or feed supplements to optimize the bird´s life cycle and to extend their production period need to be explored. This study evaluated morphometric parameters of the small intestine and gonadotropin transcript levels in Isa Brown laying hens supplemented

5. Biochemical Parameters and Histopathological Findings in the Forced Molt Laying Hens
ABSTRACT The aim of this study was to evaluate the effects of forced molting using biochemical parameters and histopathological findings in laying hens. 36 Hyline W36 strain laying hens, 90 weeks old were chosen for this research. Eight of these chickens were randomly selected and placed in a cage as the control group before the molting program began. All th

6. Sequencing and de novo assembly of the Asian gypsy moth transcriptome using the Illumina platform
Abstract The Asian gypsy moth (Lymantria dispar) is a serious pest of forest and shade trees in many Asian and some European countries. However, there have been few studies of L. dispar genetic information and comprehensive genetic analyses of this species are needed in order to understand its genetic and metabolic sensitivities, such as the molting mechanis

7. APPLICABILITY OF NON-FEED REMOVAL PROGRAMS TO INDUCE MOLTING INSTEAD OF THE CONVENTIONAL FEED WITHDRAWAL METHOD IN BROWN LAYING HENS
ABSTRACT This study was conducted to compare the applicability of non-feed removal (NFR) programs to induce molting in brown laying hens by feedusing alfalfa meal and barley grain on molting of instead of feed withdrawal in terms of performance, egg quality and profitability. A total of 240, 75-week-old Hy-Line brown laying hens were randomly divided into th

8. Experimental infection of Salmonella Enteritidis in quails submitted to forced molting by feed fasting
This study aimed at evaluating bacterial shedding, as detected in swabs, feces, and eggs of quails submitted to forced molting by feed fasting and experimentally infected with a Salmonella Enteritidis (SE) strain. In the experiment, 84 40-week-old Italian female quails were distributed in the following groups: FI (quails induced to molt by fasting and inocul

9. Use of nicarbazin, salinomycin and zinc oxide as alternative molting methods for commercial laying hens
An experiment was carried out to evaluate the performance, egg quality and morphometry of the reproductive tract, liver, pancreas and tongue of laying hens submitted to different molting methods. Two hundred and eighty eight 72-week-old Isa brown layers were distributed according to a completely randomized design with six treatments (molting methods) and six

10. Biology of Triatoma carcavalloi Jurberg, Rocha & Lent, 1998 under laboratory conditions
Introduction Triatoma carcavalloi is a wild species that is found in sympatry with Triatoma rubrovaria and Triatoma circummaculata, which are vectors of Trypanosoma cruzi currently found in rural areas of Rio Grande do Sul, Brazil. Methods Fertility was assessed and to determine the incubation period, the eggs were observed until hatching. The first meal

11. Genome-wide comparison of genes involved in the biosynthesis, metabolism, and signaling of juvenile hormone between silkworm and other insects
Juvenile hormone (JH) contributes to the regulation of larval molting and metamorphosis in insects. Herein, we comprehensively identified 55 genes involved in JH biosynthesis, metabolism and signaling in the silkworm (Bombyx mori) as well as 35 in Drosophila melanogaster, 35 in Anopheles gambiae, 36 in Apis mellifera, 47 in Tribolium castaneum, and 44 in Dan

12. Feed type for induced molting of commercial layer hens
An experiment employing three hundred and twenty 81-week-old Lohmann LSL commercial-breed hens was conducted to compare alternative induced-molting methods with the conventional method (fasting). Induced molting lasted 28 days at most, production and quality being monitored for four periods of 28 days thereafter. A completely randomized experimental design w
