The new genus Ampliphax, assigned to the Delphacini, is described and illustrated with a single new species A. grandis from Costa Rica and Panama. Ampliphax grandis is a large species with a projected head. DNA barcode data suggest, among currently barcoded taxa, an affinity to the genus Bostaera. A checklist of the delphacid species from Costa Rica, Panama, and Nicaragua based on literature an...

Antifeedant and toxic effects of leaf extracts of Syzygium cumini L., Ocimum basilicum L., Luffa aegyptica Mill., Eichhornia crassipes Mart., Tamarindus indica L., Terminalia catappa L., Limonia acidissima L., Murraya koenigii L., Breynia retusa (Dennst.)., Jatropha curcas L., Tectona grandis L., Momordica charantia L., Mangifera indica L., Ricinus communis L., and the seed extract of Madhuca i...

Numerous species of insect pests attack cotton plants, out of which the cotton boll weevil (Anthonomus grandis) is the main insect in Brazil and must be controlled to avert large economic losses. Like other insect pests, A. grandis secretes a high level of α-amylases in the midgut lumen, which are required for digestion of carbohydrates. Thus, α-amylase inhibitors (α-AIs) represent a powerful t...

Plant organisms contain a large number of genes belonging to numerous multigenic families whose evolution size reflects some functional constraints. Sequences from eight multigenic families, involved in biotic and abiotic responses, have been analyzed in Eucalyptus grandis and compared with Arabidopsis thaliana. Two transcription factor families APETALA 2 (AP2)/ethylene responsive factor and GR...

An understanding of the factors controlling plant community composition will allow improved prediction of the responses of plant communities to natural and anthropogenic environmental change. Using monitoring data from 1980 to 2009, we quantified the changes in community composition in Leymus chinensis and Stipa grandis dominated grasslands in Inner Mongolia under long-term grazing-exclusion an...

Studies were carried out for 90days on the degradation of wood wastes of four economically important Nigerian trees; Terminalia superba, Mansonia altissima, Holoptelia grandis and Milicia excelsa by white rot fungus, Pleurotus tuber-regium a Nigerian edible mushroom. The pH of the wastes dropped to 4.0/4.2, 90days after incubation. On the contrary, amino nitrogen content of the wastes increased...

Dehydrated citrus pulp and citrus pulp-protein supplements were evaluated as potential supplements for a preconditioning program. The supplements compared were no supplement, citrus pulp alone, citrus pulp with urea, and citrus pulp with added UIP. Supplemented cattle produced greater gains than unsupplemented cattle. Citrus pulp with added UIP produced the greatest ADG (0.95 lb/hd/d) whereas c...

Dof proteins are a family of transcription factors specific to the plant kingdom that contain a particular class of zinc finger DNA binding domain. Members of this family are involved in the regulation of genes related to a plethora of metabolic processes including stress or hormone response, seed and endosperm development, flowering, carbohydrate metabolism, and cell or tissue specificity. Dof...

Snakeborne Armillifer pentastomiasis is an emerging human parasitic infection in rural tropical areas where snake meat is eaten. After a series of severe ocular A. grandis larval infections and anecdotal abdominal infection in Sankuru District, Democratic Republic of the Congo, during 2014-2015, we systematically investigated possible pentastomid etiology in patients who underwent surgery in th...
