Pseudoparonella griseocoerulea Yoshii 1989
No full textPseudoparonella griseocoerulea Yoshii, 1989 Fig. 10 Pseudoparonella (Oceaniella) griseocoerulea Yoshii, 1989 Type locality. New Caledonia. Material examined. Nine females on slides and 24 in alcohol, New Caledonia: Rivière Bleue, alt. 160 m, Malaise trap, 25.xi‒ 8.xii. 1986 and 26.iii‒ 9.iv. 1987, L. Bonnet de Larbogne, J. Chazeau and S. Tillier leg. (# ρ 6 (25)ε 9, ρ 6 (25)ε 7, ρ 6 (20)ε 7). Four specimens on slides and 5 in alcohol in NJAU and others in MNHN. Remarks. Colour pattern species, Ps. bicincta, Ps. najtae, Ps. shibatai, and Ps. griseocoerulea from New Caledonia, share almost the same morphological features except colour pattern. However, intermediate colour patterns in a single population of Ps. griseocoerulea were found in this study which included pale and slightly pigmented individuals. The pale forms are identical with Ps. shibatai in colour, slightly differing from it in having 12 central macrochaetae on Th. II (15 in the latter) and 1 lateral macrochaetae on Abd. I (2 in the latter). It is not clear whether these minor chaetotaxic differences are interspecific or intraspecific characters.Published as part of Zhang, Feng & Deharveng, Louis, 2015, A revision of Pseudoparonella, Plumachaetas, Parachaetoceras and Lawrenceana (Collembola: Paronellidae), with description of three new species from New Caledonia, pp. 561-577 in Zootaxa 4058 (4) on pages 567-568, DOI: 10.11646/zootaxa.4058.4.7, http://zenodo.org/record/23635

Named after the collembologist R. Yoshii, who published major works on Paronellidae. Remarks. This new species is similar to Pl. sunae sp. nov., Pl. halmaherae (Yoshii & Suhardjono, 1992) and Pl. queenslandica (Schött, 1917) in colour pattern, long antennae with long chaetae, thick subapical chaeta of outer maxillary lobe, scale morphology and mucro. Of the three species, Pl. yoshii sp. nov. has five elongate labral chaetae in the p-row (two in Pl. halmaherae, three in Pl. sunae sp. nov. and Pl. queenslandica). Pl. queenslandica has the lanceolate unguiculus and the most abundant spiny chaetae on trochanteral organ, while other three have truncate unguiculus and fewer spiny chaetae. Of the tergal macrochaetotaxy, Pl. yoshii sp. nov. has 6, 5 central macrochaetae on Abd. I and II respectively, differing from 5, 5 in Pl. sunae sp. nov., 8, 4 in Pl. halmaherae and 4, 6 in Pl. queenslandica. Of the mucronal teeth, Pl. halmaherae has four, Pl. yoshii sp. nov. has three and Pl. sunae sp. nov. has two and as does Pl. queenslandica (Table 2).Published as part of Zhang, Feng & Deharveng, Louis, 2015, A revision of Pseudoparonella, Plumachaetas, Parachaetoceras and Lawrenceana (Collembola: Paronellidae), with description of three new species from New Caledonia, pp. 561-577 in Zootaxa 4058 (4) on pages 570-572, DOI: 10.11646/zootaxa.4058.4.7, http://zenodo.org/record/23635
Parasitismo em cochonilha pardinha Selenaspidus sp. (Homoptera, Diaspididae) por Aphytis sp. (Hymenoptera, Aphelinidae).
No full textOs pomares de citrus das principais regiões do Estado de São Paulo vem sendo prejudicados pela cochonilha pardinha Selenaspidus sp. que suga a seiva das folhas e provoca a queda dos frutos. O uso indiscriminado de defensivos químicos vem contribuindo para a destruição dos inimigos naturais e consequente proliferação da praga. Com o objetivo de estudar a frequência ou a porcentagem de parasitismo dessa cochonilha, foram feitas coletas de folhas de laranjeira para valência de um pomar de 500 alqueires localizado em Brotas - SP, em 4 épocas diferentes dos anos de 1989/90. As folhas infestadas foram examinadas ao microscópio estetoscópio para contagem das carapaças com perfurações de saída dos parasitóides. Foram colocadas algumas folhas em placas de Petri para observacao da emergência dos parasitóides. As maiores porcentagens de parasitismo foram observadas nos meses de abril/90 (21,9%) e outubro/89 (21,4%) e a menor, (2,11%) em julho/89. Os parasitóides emergidos foram identificados preliminarmente por ROBBS como sendo Aphytis sp

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
