The rates of parasitism of Theridion evexum by the parasitoid wasp Zatypota petronae, and Allocyclosa bifurca by Polysphincta gutfreundi, were followed for two years. Parasitism of T. evexum was very low (mean 1.39 +/- 1.8%), and restricted to nearly seven months of the year. Parasitism of A. bifurca was higher (mean 7.8 +/- 7.6%), and did not show a seasonal pattern. Reproduction of the host s...

The fact that living organisms exhibit certain electrical phenomena has long been known, but understanding of their significance and meaning is limited. The attempt to explain the several aspects of biological activity which can be recorded by electrical devices has, in general, rested on the assumption that the underlying phenomena are chemical and that the electrical records represent by-prod...

Mimosa é um gênero Neotropical, com grande representatividade na Caatinga, domínio onde está inserido o município de Cachoeira dos Índios. Na área estudo, os representantes do foram coletados no período dezembro/2018 a janeiro/2020. Foram levantadas nove espécies Mimosa: (M. arenosa (Willd.) Poir., M. camporum Benth., candollei R. Grether, debilis Humb. & Bonpl. ex Willd., invisa Mart. Coll...

Mimosa pudica Lin., known as chue Mue, is a stout straggling prostrate shrubby plant, with spinous stipules and globose pinkish flower heads, and grows as weed in almost all parts of the country. It is traditionally used for its various properties and hence in the present study, chloroform extract of Mimosapudica leaves has been screened for its hypolipidemic activity. Hypolipidemic activity is...

The effect of commercially available chestnut and mimosa tannins in vitro (experiment 1) or in vivo (experiment 2) on the growth or recovery of Escherichia coli O157:H7 or generic fecal E. coli was evaluated. In experiment 1, the mean growth rate of E. coli O157:H7, determined via the measurement of optical density at 600 nm during anaerobic culture in tryptic soy broth at 37 degrees C, was red...

The use of vegetable tannins is a bio-based alternative to chrome tanning. most used extracts are Mimosa and Quebracho. To improve the sustainability tanning process, chemically unmodified pine bark could be as natural source tannins. present study was aimed evaluate environmental impact powder obtain leather through life cycle assessment. Specifically, evaluation performed for both: i) tannin ...

Measuring the natural resistance of wood is fundamental for proper use. The durability five tropical species was investigated by field decay testing during exposure 360 days. Wood logs (length 0,5 m; diameter 8 cm - 12 cm) were used in this study. mass loss and index calculated visual analysis time performed all samples. samples presented evidence two different groups concerning durability. fir...

Mimosa pudica is the most abundant and problematic invasive species in tropical pastures. This study investigates the effects of two cattle grazing systems, long-term moderate grazing (LTG, 2.7 animal unit/ha/yr for 33 years) and short-term heavy grazing (STG, 5 animal unit/ha/yr for 2 years) compared with ungrazed exclosure pasture on the invasion of M. pudica and its relationship with herbage...
