1. Comportamento alimentar de paralarvas do polvo Octopus vulgaris Tipo II (Cuvier, 1797) alimentadas com artêmia enriquecida com microalgas e suplementada com DHA
ABSTRACT The inexistence of nutritionally adequate diets in paralarval rearing is the main bottleneck for commercial production of the common octopus Octopus cf. vulgaris. We report the feeding behavior of O. vulgaris Type II paralarvae fed on Artemia sp (0.1 individual. mL-1) nauplii enriched with microalgae Isocrysis galbana and Pavlova lutheri microalg

2. Mass Balance Applied to Brazilian Conventional Broiler Houses during One Production Cycle
ABSTRACT Brazil plays an important role in global poultry production as it is the world's largest chicken exporter and the third largest broiler producer. Despite the development achieved by the Brazilian broiler industry as a result of the integrated production system, many obstacles still need to be overcome, in particular, housing environment. In this reg

3. Artificial diet for laboratory rearing of Condylorrhiza vestigialis (Guenée, 1854) (Lep.: Crambidae)
ABSTRACT The Brazilian Poplar Moth, Condylorrhiza vestigialis (Guenée), compromises the wood productivity of poplar trees (Populus sp.), mainly affecting the matchstick industry in southern Brazil. Considering the lack of information on rearing techniques for this insect, the objective of this study was to develop an artificial diet to rear C. vestigialis w

4. PRODUCTIVE PERFORMANCE OF WHITE LEGHORN HENS BASED ON THE TYPE OF HOUSING DURING REARING: FLOOR VERSUS CAGE
ABSTRACT Poultry farmers in the southeastern of Mexico consider that the productivity of the hens that comes from rearing on floor has a higher productive performance than reared hens in cages, mainly due to higher percentage of egg laying and lower mortality. The aim of this study was to evaluate the productive performance of the laying hen in relation to t

5. Size and flight ability of Telenomus remus parasitoids reared on eggs of the factitious host Corcyra cephalonica
ABSTRACT In two independent bioassays, size and flight ability of parasitoids reared on eggs of Corcyra cephalonica for 19 generations and parasitoids reared on a natural host (Spodoptera frugiperda eggs) for 250 generations were compared as fast quality control procedures for insect rearing. The size of parasitoids was examined by morphometric analysis usin

6. 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

7. 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

8. Distinct genetic structure in populations of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) shown by genetic markers ISSR and COI gene
Distinct genetic structure in populations of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) shown by genetic markers ISSR and COI gene. Green lacewings are generalist predators, and the species Chrysoperla externa presents a great potential for use in biological control of agricultural pests due to its high predation and reproduction capacities, as we

9. 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

10. Use of artificial substrates of different colors for oviposition by the brown stink bug Euschistus heros (Hemiptera, Pentatomidae)
Aiming to contribute to a rearing methodology for the brown stink bug, Euschistus heros, in the laboratory, we evaluated oviposition on artificial substrates of different colors. During six days, oviposition was evaluated daily, by counting the total number of eggs, number of clutches, and eggs/clutch. Females laid 12,463 eggs, in 1,677 clutches, resulting i

11. Effect of Carbon dioxide (CO2) on mortality and reproduction of Anagasta kuehniella (Zeller 1879), in mass rearing, aiming at the production of Trichogramma spp.
Ovos de Anagasta kuehniella (Zeller, 1879) são muito utilizados para a criação massal de Trichogramma spp. e de outros parasitóides e predadores, sendo comercializados em muitos países. O objetivo deste trabalho foi avaliar o efeito do dióxido de carbono (CO2), proveniente do metabolismo larval, em parâmetros biológicos de A. kuehniella, principalmen

12. ESTUDO DA RECRIA DE NOVILHAS DE CORTE EM PASTAGENS CULTIVADAS DE VERÃO / STUDY OF BEEF HEIFERS REARING ON WARM-SEASON PASTURES
Heifers rearing is a determinant step of efficiency in beef cattle production systems on pastures. Several experiments have tested alternative uses for tropical grasses to heifers rearing. In order to summarize results and making not visible relationships evident in these individual experiments an analysis was performed in a set of data from six experiments
