1. Autochthonous microalgae cultivation with anaerobic effluent: isolation of strains, survivorship, and characterization of the produced biomass
Resumo Seis cepas de Chlorophyta foram isoladas do efluente de um reator anaeróbio tratando esgoto sanitário e identificadas como Desmodesmus sp. L02, Chlorococcum sp. L04, Coccomyxa sp. L05, Chlorella sp. L06, Scenedesmus sp. L08 e Tetradesmus sp. L09. As cepas de microalgas foram cultivadas em efluente não-esterilizado em condições de laboratório par

2. Fertility Life Table, Population Parameters and Biotic Potential of Helicoverpa gelotopoeon (Dyar) (Lepidoptera: Noctuidae)
Abstract Helicoverpa gelotopoeon is an endemic pest of South America that affects soybean and other important crops. Life tables are a fundamental tool used to study insect populations, resulting in crucial information for integrated pest management programs. Therefore, the aim of this study was to evaluate the biotic potential and the construction of a life

3. Differential survivorship of congeneric ornamental fishes under forecasted climate changes are related to anaerobic potential
Abstract Two Amazonian closely related tetras – cardinal Paracheirodon axelrodi and green neon P. simulans – were artificially acclimatized to environmental chambers mimicking future climate change scenarios (mild, moderate and extreme), using a microcosm facility. P. simulans survived (100%) to all scenarios after 30 days exposure, while P. axelrodi pre

4. Evidence of the effects of fire on branching and leaf development in cerrado trees
ABSTRACT We discuss evidence of effects of an accidental fire on shoot growth and leaf development in six cerrado tree species with distinct leaf phenologies. Buds of all six species were marked before shoot and leaf emergence in the dry season. After fire, leaf and shoot growth were monitored weekly and specific leaf area (SLA) was determined. Shoot order w

5. Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert
Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert. The spatial distribution of the immature stages of the leaf miner Angelabella tecomae Vargas & Parra, 2005 was determined at two intra-plant levels (shoot and leaflet) on the shrub Tecoma fulva fulva (Cav.)

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. Estudo da participação do colágeno V no câncer de pulmão, especificamente no carcinoma não de pequenas células / Study of the involvement of collagen V in lung cancer specifically in non-small cell carcinoma
O colágeno V vem emergindo como um potente indutor de morte celular (apoptose) via caspase. Nosso objetivo, neste estudo, foi examinar a interface entre o colágeno dos tipos I, III e V, apoptose tumoral e endotelial, angiogênese e células imunes, assim como o impacto desses fatores no prognóstico de pacientes com carcinomas não de pequenas células (CN

8. Reproductive behaviours and host plant selection mediated by semiochemicals in Neoleucinodes elegantalis (Lepidoptera: Crambidae) / Comportamento reprodutivo e seleção de hospedeiro mediada por semioquímicos em Neoleucinodes elegantalis (Lepidoptera: Crambidae)
The searching behaviour in insects is important to acquire food, meeting mates, oviposition sites location and protect the insects against predators. Thus, the majority of herbivorous insects select their host plant and, in particular, the plants part, which it will feed and oviposit on, using, among other tools, host plants semiochemicals. This paper aims:

9. Antibiosis and antixenosis of six commonly produced potato cultivars to the green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae)
The antibiotic and antixenotic resistance of six commonly produced potato cultivars in Iran including Aozonia, Agria, Cosima, Cosmos, Kondor and Savalan to the green peach aphid, Myzus persicae Sulzer, were investigated under laboratory conditions at 20 ± 2ºC, 65 ± 5% RH and 16:8h (L:D) in 2009. Antibiosis experiments showed significant differences in the

10. Intraspecific interactions in the mangrove crab Ucides cordatus (Decapoda: Ocypodidae) during the metamorphosis and post-metamorphosis periods under laboratory conditions
Current efforts for restocking natural populations of the mangrove crab Ucides cordatus (Linnaeus, 1763) in Brazil have focused on developing a methodology for stimulating the metamorphosis of U. cordatus larvae at a large scale. The aim of the present study was to compare the mortality rates both in individual and mass conditions, during the induction of me

11. Survivorship and Egg Production of Phytophagous Pentatomids in Laboratory Rearing
Survivorship and reproductive performance of the pentatomids Euschistus heros (F.) (EH), Nezara viridula (L.) (NV), and Dichelops melacanthus (Dallas) (DM) were tested in the laboratory. A mixture of natural foods (pods of green beans, Phaseolus vulgaris, raw shelled peanuts, Arachis hypogaea, and fruits of privet, Ligustrum lucidum, and 50 pairs/box (25 x 2

12. 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. Survival rate of immature stages and survivorship and reproduction of adults
