1. Performance of Commercial Laying Hen Submitted to Different Debeaking Methods
ABSTRACT Among the several factors required in breeding laying hens, debeaking is a factor that interferes with batch performance and affects animal welfare. Thus, the objective of this study was to evaluate three different debeaking procedures and to verify the best technique to be used. For this, the performance of the birds, the incidence of cannibalism,

2. COMPUTATIONAL FLUID DYNAMICS (CFD) APPLICATION FOR VENTILATION STUDIES IN BROILER HOUSES
ABSTRACT With the recent increase in the number of acclimatized broiler houses in Brazil, design and adaptation of facilities to withstand the tropical weather conditions enabling the maintenance of ideal conditions without increasing costs have been major challenges. The aim of this study was to evaluate the ventilation system in solid-wall broiler houses u

3. Efficiency of the induced mating technique for Toxorhynchites theobaldi (Diptera, Culicidae)
Toxorhynchites mosquitoes play important ecological roles in aquatic microenvironments, and are frequently investigated as potential biological control agents of mosquito disease vectors. Establishment of Toxorhynchites laboratory colonies can be challenging because for some species, mating and insemination either do not occur or require a prohibitive amount

4. Large scale artificial rearing of Anastrepha sp.1 aff. fraterculus (Diptera: Tephritidae) in Brazil
Some species of the genus Anastrepha (Diptera: Tephritidae) are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality

5. New method for rearing Spodoptera frugiperda in laboratory shows that larval cannibalism is not obligatory
New method for rearing Spodoptera frugiperda in laboratory shows that larval cannibalism is not obligatory. Here we show, for the first time, that larvae of the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera, Noctuidae), can be successfully reared in a cohort-based manner with virtually no cannibalism. FAW larvae were reared since the second instar

6. Mass-rearing of Mediterranean fruit fly using low-cost yeast products produced in Brazil
Ceratitis capitata is one of the most important pests of fruits for exportation, and Sterile Insect Technique (SIT) has been the most efficient and environmental friendly technique used to control fruit fly populations around the world. A key goal in achieving a successful SIT program is a mass rearing system producing high quality insects at low cost. Provi

7. Bioecologia e competição de duas espécies de parasitoides neotropicais (Hymenoptera: Braconidae e Eulophidae) de Liriomyza sativae Blanchard, 1938 (Diptera: Agromyzidae) / Bioecology and competition of two neotropical parasitoid species (Hymenoptera: Braconidae and Eulophidae) of Liriomyza sativae Blanchard, 1938 (Diptera: Agromyzidae)
We studied the biology of two species of parasitoids associated with Liriomyza sativae Blanchard, 1938 in the state of Rio Grande do Norte (RN), Brazil: the koinobiont larval-pupal parasitoid Opius (Gastrosema) scabriventris (Hymenoptera: Braconidae) and the larval idiobiont parasitoid Chrysocharis vonones (Hymenoptera: Eulophidae). The following parameters

8. How to increase the population of a Phlebotomus perniciosus (Diptera: Psychodidae) colony: a new method
The sandfly Phlebotomus perniciosus is the most widespread vector of Leishmania infantum in Spain. Laboratory colonisation represents the most feasible source of information on the biology of these insects, but in conducting any study, the density of individuals in the colony may drop to such an extent that it is sometimes difficult to recover the initial po

9. Técnica de Criação e Aspectos Biológicos de Atheloca subrufella (Hulst) (Lepidoptera: Phycitidae) em Frutos de Coqueiro
Rearing Technique and Biological Traits of Atheloca subrufella (Hulst) (Lepidoptera: Phycitidae) in Coconut Fruits. Larvae of the coconut moth Atheloca subrufella (Hulst) develop in flowers and fruits of coconut, Cocos nucifera, causing precocious abscission of these structures and, hence, yield decrease. This work studied a feasible and suitable rearing tec

10. Euschistus heros mass rearing technique for the multiplication of Telenomus podisi.
The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively.

11. Criação massal em dieta líquida e radioesterilização da mosca-sul-americana Anastrepha sp.1 aff. fraterculus (Wied., 1830) (Diptera: Tephritidae) / Mass production in liquid diet and radioesterilização of South American fruit fly Anastrepha sp.1 aff. fraterculus (Wied., 1830) (Díptera: Tephritidae)
Tanto as técnicas de controle biológico quanto a Técnica do inseto estéril (TIE), são utilizadas em vários países para o controle, supressão e até mesmo erradicação de moscas-das-frutas e outras pragas da agricultura, pecuária e saúde publica. O uso de tais técnicas minimiza o emprego contínuo de inseticidas, protege o ambiente e se adequa aos

12. Utilização de complexos orgânicos de minerais no pré-parto de vacas, e durante o aleitamento de bezerras holandêsas
The objectives of this experiment were to evaluate the effect of complexed minerals use during prepartum as well as the performance and necessity or not of mineral supplementation during those cows rearing. In the first part of experiment 128 multiparous Holstein dairy cows were used and randomly assigned into two groups: MI-65 cows groups (cows consuming io
