Pre-columbian mycobacterial genomes reveal seals as a source of new world human tuberculosis
(Springer Nature, 2014-08)Modern strains of Mycobacterium tuberculosis from the Americas are closely related to those from Europe, supporting the assumption that human tuberculosis was introduced post-contact1. This notion, however, is incompatible ... -
Precocious sexual signalling and mating in Anastrepha fraterculus (Diptera: Tephritidae) sterile males achieved through juvenile hormone treatment and protein supplements
(Cambridge University Press, 2013-02)Sexual maturation of Anastrepha fraterculus is a long process. Methoprene (a mimic of juvenile hormone) considerably reduces the time for sexual maturation in males. However, in other Anastrepha species, this effect depends ... -
Predatory capacity of Tupiocoris cucurbitaceus (Hemiptera Miridae) on several pests of tomato
(Department of Agroenvironmental Sciences and Technologies, Università di Bologna., 2019)The predator Tupiocoris cucurbitaceus (Spinola) is frequently found preying on whiteflies in greenhouse tomato without pesticide use in Argentina. This study evaluated its preying capacity on several pests, determining the ... -
Prediction of aquaporin function by integrating evolutionary and functional analyses
(Springer, 2014-02)Aquaporins (AQPs) are a family of channel proteins, which transport water and/or small solutes across cell membranes. AQPs are present in Bacteria, Eukarya, and Archaea. The classical AQP evolution paradigm explains the ... -
