1. A new device to autonomously feed individualized mantids on extended periods of time
ABSTRACT Mantises can live for many months, are naturally voracious, and feed invariably on live prey. Many species have a propensity for cannibalism and cannot be kept together for most of their life cycle, which makes large-scale rearing typically time-consuming, thus easily becoming prohibitive. This is particularly true for early instars, because they ar

2. BEAK TRIMMING BY INFRARED RADIATION OF LAYERS
ABSTRACT This study aimed at evaluating beak-trimming methods and intensities on the performance, beak length and uniformity, and egg parameters of commercial layers. During the rearing period, birds were distributed in randomized blocks, with a 2x3 factorial design + two treatments, consisting of beak trimming with infrared (IR) radiation (moderate or sever

3. Pina Bausch en Brasil: fruta, vestidos, felicidad y Água
Abstract: This article approaches the work of Pina Bausch and the creative processes of the Tanztheater Wuppertal Company. The focus is on the work developed during her residencies in several cities around the world, a cartographic repertoire that provides a trans-border and trans-modern historical perspective from the stage. Through the analysis of several

4. Association between molecular markers and behavioral phenotypes in the immatures of a butterfly
Abstract Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs. Previous work has estimated the heritability of kin recognition in H. erato phyllis to lie between 14 and 48%. It has furthermore been shown that the

5. 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,

6. 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

7. Efeito da disponibilidade de sítios de nidificação sobre o sistema de acasalamento e o cuidado paternal em um opilião neotropical (Arachnida: Opiliones) / Effects of reproductive sites availability in the mating system and in the paternal care of a Neotropical harvestmen (Arachnida: Opiliones)
Cavidades naturais constituem um recurso reprodutivo monopolizável, cuja disponibilidade determina a intensidade da competição macho-macho que, por sua vez, pode influenciar os custos do cuidado paternal, pois quanto maior o risco de perda do recurso, menor deve ser a freqüência de forrageio dos machos. Fêmeas do opilião Magnispina neptunus utilizam c

8. Replacement of moist ingredients in the feed training of carnivorous fish
The study evaluated the replacement of bovine heart by gelatin in the feed training of carnivorous fish, using giant trahira (Hoplias lacerdae) as an experimental model. A completely randomized design with four treatments and five repetitions was employed. The treatments were composed of wet ingredients beef heart (control), gelatin diluted in water, gelatin

9. Saline water for juvenile giant trahira during feed training
The objective of this study was to investigate the effect of different water salinities on juvenile Hoplias lacerdae during feed training. Salinity levels of 0, 3, 6 and 9 g salt L-1 were used. Juveniles (3.33±0.1 cm and 0.6±0.09 g) were stocked at a density of six fish L-1 in aquaria (10 L volume) with supplementary aeration. Weight gain, length gain, and

10. Interação trófica entre Podisus nigrispinus e Supputius cincticeps (Heteroptera: Pentatomidae) / Trophic interaction between Podisus nigrispinus and Supputius cincticeps (Heteroptera: Pentatomidae)
Prey may be more or less consumed by control biologic agents and presents three kinds of interspecific interactions, (1) synergism, increase of mortality of prey comparing to each natural enemy independently, when the foraging of one species facilitates the capture of pest by another natural enemies. (2) Total mortality of the pest to natural enemies equals
