Effects of foliar fertilization of common bean (Phaseolus vulgaris, L.) during the seed-filling stage

An experiment was carried out with common bean (Phaseolus vulgaris, L.) in a Red Yellow Latossol, sandy phase, in order to study the influence of foliar spraying of the Hanway nutrient solution (NPKS) at grain filling stage on: 1) grain yield; 2) the uptake of fertilizer and soil nitrogen by this crop through the root system and 3) the efficiency of utilization of the nitrogen in the foliar spray solution by the grain. The results of this experiment showed that the foliar application of the Hanway solution with ammonium nitrate at the pod filling period caused severe leaf burn and grain yield was inferior to that of the plants which received a soil application of this fertilizer at the same stage. These facts can be attributed to the presence of ammonium nitrate in the concentration used. The composition of final spray was: 114,28 Kg NH4NO3 + 43,11 Kg potassium poliphosphate + 12,44 Kg potassium sulphate per 500 litres. The uptake of nitrogen fertilizer through the root system and the efficiency of its utilization was greater than that through the leaves.

Effects of ethephon and urea on ripening of fruits and leaf abscission of coffee (Coffea arábica L.)

A field experiment was carried out to investigate the effects of ethephon and urea on ripening of fruits and leaf abscission of coffee plant. Ethephon (2-chloroethane phosphonic acid) sprays were applied to green Coffea arábica berries 26 days before counting date in concentrations of 0.5 and 0.25 ml/1 from Ethrel (240 a.i./l). The chemical accelerated the onset of fruit ripening at both concentrations. The efficacy of ethephon was increased adding urea. Ethephon 0.5 ml/1 promoted abscission of leaves and low concentration reduced shedding of leaves. The treatments did not affect the growth and production on the next harvest.

An evaluation of natural infestation by leaf pests on soybean (Glycine max (L.) Merrill) cultivars

Damage caused by leaf pests of soybean on five cultivars was evaluated. Afield experiment was carried out at the Piracicaba region, cultivars Davis, IAC 73-228, PI 227.687,PI 171.451, and PI 229.358 having been compared. Leaf damage was produced by natural infestation of Anticarsia gemmatalis and Plusia sp. Cultivar PI 171.451 showed lower comsumption of leaves in relation to control ('Davis') and other cultivars. Damage was more serious on IAC 73-228 than on PI 227.687 and PI 229.358.

Three new species of Mesabolivar (Aranea, Pholcidae) from leaf litter in urban environments in the city of São Paulo, São Paulo, Brazil

In this study we describe three new litter inhabiting species of Mesabolivar González-Sponga, 1998 from nine urban forest remnants in the metropolitan region of the city of São Paulo, Brazil: M. forceps, M. mairyara and M. cavicelatus. In three of these remnants, we conduced a three year sampling using pitfall traps. Mesabolivar forceps sp. nov. was the most abundant pholcid (n=273 adults), always present in the samples, but with highest numbers in spring and summer. Mesabolivar mairyara sp. nov. was the second most abundant species (n=32), but the majority of individuals were collected in March 2001. Only three individuals of M. cavicelatus sp. nov. were collected.

Ecological relations between mangrove leaf litter and the spatial distribution of the gastropod Melampus coffeus in a fringe mangrove forest

Leaf litter represents a food source to many organisms that may directly contribute to organic matter decomposition. In addition, the physical presence of these vegetal detritus contributes for the modification of some environmental areas and produce microhabitats that may act as a refuge against predators and desiccation for many animals. The pulmonate gastropod Melampus coffeus (Linnaeus, 1758) (Ellobiidae) is a very common specie in Atlantic Coast mangrove forests and feeds on fallen mangrove leaves. It was hypothesized that the spatial distribution of Melampus coffeus is directly affected by mangrove leaf litter biomass deposition. Thus, this research aimed at evaluating the spatial distribution of these gastropods in relation to the biomass of mangrove leaf litter through a twelve-month period. The study area was established in the middle estuary of Pacoti River, state of Ceará, Brazil where two adjacent zones with different topographic profiles were determined. Samples of Melampus coffeus and leaf litter were collected monthly, throughout a year, from the mangrove ground surface. The results indicated that the presence of twigs in mangrove litter favor the occupation by smaller individuals of M. coffeus, probably because smaller individuals are more susceptible to predator attacks and desiccation than larger ones, and twigs and branches may provide a safe microhabitat.

Alterações nucleares das cellulas do figado nas infecções de Macacus Rhesus e M. Cynomolgus pelo virus da febre amarella

No figado de um Macacus rhesus inoculado por BEAUREPAIRE ARAGÃO com sangue deum caso benigno de febre amarella e no qual elle descreveu symptomas e lesões typicas semelhantes ás obidas por STOKES, BAUER e HUDSON pela inoculação com o virus africano no mesmo animal, encontrámos alterações nucleares da mesma natureza das assignaladas, no herpes zoster, herpes symptomatico, varicella e virus III do coelho e descriptas ora sob o nome de "inclusões acidophilas intranucleares" (LIPSCHÜTZ, GOODPASTURE), ora sob o de "degeneração oxychromatica" (LAUDA e LUGER). Alterações nucleares semelhantes da cellula hepatica encontrámos, posteriormente em 13 M. rhesus e 2 M. cynomolgus inoculados com e virus brasileiro da febre amarella o qual fôra isolado independentemente por BEAUREPAIRE ARAGÂO e depois por A. MARQUES DA CUNHA e J. MUNIZ de dois casos benignos de febre amarella, tendo sido um dos macacos injectado directamente com o sangue do doente; dois macacos foram inoculados com Aedes aegypti infectados em homem e em macaco; os animais foram anímaes empregados em passagens em serie do virus pelo macaco, e talvez esse facto explique até certo ponto, as notaveis differenças por vezes encontradas nas alterações histopathologicas do figado, visto como, em condições naturaes, o virus nunca passa directamente de homem para homem. A intensidade com que se apresenta a degeneração oxychromatica de modo algum está na dependencia das alterações do conteúdo gorduroso, necrose e necrobiose encontradas; em um caso, ella era a unica alteração presente no figado, sendo então particularmente intensa. As inclusões acidophilas intranucleares (degeneração oxychromatica) não foram encontradas em diversos M. rhesus não inoculados e mortos por causas obscuras; no entanto, em taes figados eram presentes infiltração e degeneração gordurosas associadas a alterações de necrose e necrobiose. Alguns estadios (figuras intranucleares "em borboleta" e "em ameba", v. fig. g e h, Est. colorida) sendo abundantes, facilitam, em virtude de sua configuração especial, o reconhecimento da degeneração oxychromatica em córtes feitos segundo uma technica rapida (pequenos fragmentos de figado fixados em formol aquecido a 60°C.-trinta minutos, córtes em congelação, hematoxylina, eosina, alcool absoluto, phenol-xylol-creosoto, xylol, balsamo), não tendo, afóra isso, importancia especial. Ao passo que a degeneração e infiltração gordurosa, bem como a necrose e a necrobiose da cellula hepatica apresentam variações consideraveis em sua intensidade de um para outro animal em uma passagem em serie não interrompida do virus pelo M. rhesus, chegando mesmo a faltar interamente em dois animaes cujo figado, no entanto, mostrou-se capaz de reproduzir symptomas e lesões typicas na passagem seguinte, as inclusões acidophilas intranucleares (degeneração oxychromatica), de regra, se encontram com muito maior regularidade...
