Microspines in the pylorus of Pseudonannolene tricolor and Rhinocricus padbergi (Arthropoda, Diplopoda) Iheringia, Sér. Zool.
Miyoshi,Akio R.; Gabriel,Vagner A.; Fantazzini,Evandro R.; Fontanetti,Carmem S..
The aim of this paper is to report the morphology and distribution of microspines in diplopods pylorus, as these are important structures present along the alimentary tract of arthropods. The morphology of the internal surface of the pylorus of Pseudonannolene tricolor Brolemann, 1901 and Rhinocricus padbergi Verhoeff, 1938 was analyzed by SEM. Pseudonannolene tricolor presents two morphologically distinct pyloric regions: anterior and posterior. The first region is characterized by the presence of thin microspines that increase in number and size towards the posterior portion; the second region presents smaller and triangular-shaped microspines distributed throughout small plates. The pylorus of R. padbergi does not present differentiated regions; the...

Wood-plastic composites from residues of three forest species PFB - Pesquisa Florestal Brasileira
Talgatti, Maiara; Baldin, Talita; Silveira, Amanda Grassmann da; Santini, Elio José; Vidrano, Bibiana Regina Argenta.
This study aimed to evaluate physical and mechanical properties of wood-plastic composites using materials of low processing level. Residues from carpentry as wood shavings from three forest species (Pinus elliottii, Hovenia dulcis and Maclura tinctoria), and thermoplastic type were used. Data were submitted to Duncan’s test with 95% confidence. In relation to the modulus of rupture (MOR) and elasticity- (MOE), all treatments presented successful results, without difference. For the tests of internal bond and screw pullout, the results were not satisfactory. For this last test, the best result was for Hovenia dulcis. In relation to swelling in 2 h and 24 h, all treatments presented positive results. In general, the results were not influenced by the...

Pineus boerneri Annand, 1928 (Hemiptera, Adelgidae) - a new species to Brazil: morphology of eggs, nymphs and adults Rev. Bras. entomol.
Lazzari,Sonia Maria Noemberg; Cardoso,Josiane Teresinha.
Pineus boerneri Annand, 1928 (Hemiptera, Adelgidae) _ a new species to Brazil: morphology of eggs, nymphs and adults. Pineus boerneri represents the first Adelgidae species recorded in Brazil. This aphid species forms extensive colonies on branches and trunk of Pinus spp., with apterous oviparous females, eggs and nymphs covered with white wax. The aim of this research is to study the morphology of eggs, nymphs, and adults to provide useful data for species identification in order to solve taxonomic issues. The study was based on morphometric data and optical and scanning electron microscopy images. First instar nymphs are active and can be easily distinguished from the others by their elongate minute yellowish body; well developed legs bearing a pair of...
