Última Ideal culture conditions for Dicyma pulvinata conidia mass production PAB Melo,Débora Ferreira; Mello,Sueli Corrêa Marques de. The objective of this work was to set up ideal conditions for conidia mass production of Dicyma pulvinata. Four isolates were compared in terms of their growth and conidia production on various substrates (grains of parboiled rice, common rice, maize and wheat, besides chipped maize and rice husk), temperatures (19, 22, 25, 28 and 31ºC), growth containers (aluminum trays, polypropylene bags and Erlenmeyers) and light regimes (continuous darkness, 6 and 12 hours of light/darkness, and continuous light). Temperature effects on conidia germination capacity were also evaluated. The experiments were done in randomized complete block designs, in factorial arrangements (isolates x treatments - substrates, containers, temperatures and light regimes), with four...

O propósito deste artigo é refletir sobre o processo de constituição e de construção do estigma cognitivo que tem caracterizado o campesino como um indivíduo “incapaz”. Os argumentos desenvolvidos aqui estão fundamentados primeiro na desarticulação do seringal e, segundo, na reprodução das disposições na “nova” configuração, incorporadas que foram enquanto seringueiro. A análise procura mostrar que a estratégia utilizada por esses campesinos para se articular com a configuração geral não são os mecanismos normais do campo econômico. Essa questão tem sido ignorada pelo Estado com implicações que penalizam os próprios ex-seringueiros e a sociedade. The objective of this paper is to discuss the setting and construction process of cognitive stigma that has...

Calacarus heveae Feres, 1992 is an Eriophyidae mite described from rubber tree (Hevea brasiliensis Muell. Arg.) in the northwest region of the State of São Paulo. This mite prefers the adaxial face of the folioles and it can reduce the brightness of the leaves, turning them progressively yellow and brownish, and consequently premature fall. The aim of this work was to study the biology of C. heveae in laboratory, on detached rubber tree folioles. The study was conducted at 28±1 ºC in the photophase (12h), 25±1 ºC in the dark phase (12h), and 90±5% relative humidity. The study was initiated with a total of 59 eggs. The average duration of egg, larva and nymph stages was 5.8, 2.0 and 1.4 days, respectively. The period from egg to adult lasted 9.3 days, and...

Rubber tree cultivation [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.] uses mostly the budding propagation method, however the expected stand uniformity due to the use of vegetative propagation is theoretical, since high variation for yield and vigor is caused by rootstock influence. The objective of this study was to assess several combinations between clonal rootstocks and clone scions through diallel analysis, aiming at high productivity and vigor. Data consisted of five years of dry rubber yield and girth at panel opening from an experiment using a split-plot design with four replications, conducted at Pindorama, SP, Brazil, considering six rootstocks (GT 1, IAN 873, PB 235, RRIM 600, RRIM 701 and unselected seedlings) and six scions (GT 1,...

Basic knowledge of genetic characteristics of populations is necessary to conduct effective breeding and selection. The objective of this paper is describing the genetic variation of rubber yield and the correlation with other traits, and estimating the genetic parameters for girth growth and total number of latex vessels. Sixty seven clones of Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg. were tested at five sites during 10 years. Characters girth growth at panel opening and rubber yield, showed broad sense heritability on plot mean level, from 0.32 to 0.66 and 0.59 to 0.92, respectively. Predicted genetic gains equal to 0.73 cm and 0.79 g increase respectively on girth and yield in the opening panel and mature phases seems realistic, even with...

Rubber industry has increased the requirements for quality and uniformity of natural rubber produced in Brazil. Technological properties of latex and natural rubber of clones GT 1, PB 235, IAN 873 and RRIM 600 [Hevea brasiliensis (Willd. Former Adr. de Juss.) Muell.- Arg] were evaluated by standard methods of the dry rubber content (DRC%), percentage of nitrogen (N%) and percentage of ashes (ASH%) in two consecutive years; data were correlated with temperature and precipitation. Properties of latex and natural rubber varied (P < 0.01) as a function of clone type and among tappings. DRC decreased in the beginning of the dry season (May to June) and N% and ASH% increased in the same period. April to June was a critical period, when N% was above 0.60%, out...

The objective of this study was to compare household income and expenditure between rubber tree and sugarcane farmers. The purposive sampling technique was used for data collection, and a structured questionnaire was used to interview a total of 100 farmers. A descriptive analysis was applied. The results indicated that in 2000-2010, the household income of rubber tree farmers was higher than those sugarcane farmers, especially in long run. The household consumption has increased during 2000-2010. The rubber tree farmers expensed their consumption in food item more than rice, but it was contrary for the sugarcane farmers. The net income of the rubber tree farmers was also greater than the sugarcane farmers; even it was negative in 2005. This can imply that...

This mite was first found in northwestern São Paulo State, Brazil. Feres (1998) described two additional species, Shevtchenkella petiolula and Phyllocoptruta seringueirae, from the same host and from same region. The commercial monocultural planting of the Amazonian rubber tree in the northwestern region of São Paulo State started about 18 years ago. In the Amazonian region, the native rubber tree grows dispersed between other plant species. Until now these eriophyids have been collected only on monocultural plantings.

A mancha areolada de Thanatephorus é uma das doenças mais importantes da seringueira (Hevea brasiliensis) na Amazônia brasileira. Além da seringueira, o fungo T. cucumeris (fase anamórfica Rhizoctonia solani) causa doenças foliares em outras espécies nativas ou cultivadas na região. Baseando-se na ausência de informações sobre quais os grupos de anastomose (AG) de R. solani estão associados à seringueira e a outros hospedeiros na Amazônia, testou-se a hipótese de que estes isolados pertencem a AG distintos. Também não há informação sobre a patogenicidade cruzada, à seringueira, de isolados provenientes de outros hospedeiros. A determinação do AG foi efetuada com base em análise filogenética da região ITS do rDNA. Concluiu-se que um novo subgrupo de R....

Patches of natural vegetation have been reported to play an important role in the preservation of diversity of natural enemies of pest arthropods. Euphorbiaceous plants are common in natural and regenerated ecosystems in the State of São Paulo. Those plants may act as reservoirs of phytophagous mites and their respective natural enemies, both of which are also found on cultivated plants of the same family. The objective of the work reported in this paper was to study the diversity of mite species on euphorbiaceous plants in three regions of the State of São Paulo, and to compare the similarities between those regions in relation to the composition of the mite fauna they harbor. A total of 31,603 mites belonging to 105 species in 74 genera and 16 families...

The objective of this study was to assess genotype-year interaction and determine temporal stable genotypes across six years of rubber yield evaluation. Stability analyses were performed by Eberhart and Russell method for rubber yield. Twenty-five genotypes were analyzed in a randomized complete block design with three replications. The best genotype in one year was not same always in the other year. The genotype components were partitioned into linear (genotypes within year) and nonlinear (pooled deviations) components. Significant mean square for linear components was predictable. This indicated that the performance of genotypes across the years for rubber yield could be predicted. Among the analyzed genotypes the IAC 40 also was considered highly...

ABSTRACT The use of the Hevea brasiliensis tree in latex rubber production has resulted in a consolidated role of this tree in the Brazilian economy. However, at the end of the productive cycle of the tree that lasts for approximately 25 years, the timber resulting from this venture has no added value and is usually used for the production of firewood. In order to introduce this species into the furniture and civil construction industry, the current study aimed to evaluate the quality of particleboard produced by adding Pinus oocarpa wood with Hevea brasiliensis wood in different ratios. The particleboards were produced with a nominal density of 0.60 g/cm³ and 8% (wt%) urea-formaldehyde resin and pressed at 160 °C for 8 min at a pressure of 4.0 MPa. The...
