Okro and Peppper were intercropped in a randomised complete block design with three replicates to assess the effect of this on the population of several insect pest of Okro. Five pests of Okro were recorded: Podagrica uniforma; Podagrica sjostedti; Oxycarenus hyalipennis; Cosmophila flava and Dysdercus superstitiosus. However, there were no significant difference in the population of these inse...

The genus Rhipidia Meigen, 1818 from China is reviewed. Twenty-one species are presented, of which seven species, Rhipidia (Rhipidia) bilobata sp. nov., R. (R.) flava sp. nov., R. (R.) lobifera sp. nov., R. (R.) longa sp. nov., R. (R.) sejuga sp. nov., R. (R.) shennongjiensis sp. nov., and R. (R.) spinosa sp. nov., are described as new to science, and one species, R. (R.) reductispina Savchenko...

All hypocrealean species of the genus Geosmithia are anamorphic fungi with connections to bark beetles. G. fassatiae, G. langdonii and G. obscura are described as new sympatric species associated with Scolytus carpini, S. intricatus and S. rugulosus in Central Europe. The species represent a complex of three sister taxa with affinities to G. flava that may be distinguished by differences in mor...

The work described here was prompted by our interest in the pathogenesis of spontaneous cervical subluxation in rheumatoid arthritis. Anatomical studies of rheumatoid cervical spines (Ball, 1958) had revealed destructive inflammatory lesions in the disks and posterior spinal joints, but not in the ligamenta flava; segmental ankylosis, erosion of certain ligamentous attachments, and disk degener...

The center of diversity of Argentinean orchids is in the northeast region of the country. Chromosome numbers and karyotype features of 43 species belonging to 28 genera are presented here. Five chromosome records are the first ones at the genus level; these taxa are Aspidogyne kuckzinskii (2n = 42), Eurystyles actinosophila (2n = 56), Skeptrostachys paraguayensis (2n = 46), Stigmatosema polyade...

Clusia fluminensis Planch. & Triana (Clusiaceae Lindl.) is a native species found in regions of high luminosity and water restriction. The aim of this study was to evaluate the antioxidant activity of Clusia fluminensis crude extracts through the scavenging of the stable free radical DPPH, and the determination of flavones and flavonols content in these extracts. The fruit acetonic extract show...

A coccoid actinobacterium strain (designated YIM 70178(T)) was isolated from a soil sample collected in Qinghai Province, China. The isolate grew well with an optimum salt concentration of 10-15% (KCl, w/v) but scarcely or not at all without salt. The cell-wall peptidoglycan type was A4alpha, L-Lys-gly-L-Glu. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, an unknown p...
