The asymmetric unit of the title hydrated salt, C22H26F2NO4(+)·Cl(-)·0.5H2O, consists of an (S,S,S,S)-nebivolol {nebivol = bis-[2-(6-fluoro-3,4-dihydro-2H-1-benzopyran-2-yl)-2-hy-droxy-eth-yl]ammonium} cation, a chloride anion and a half-occupancy water mol-ecule. The dihedral angle between the mean planes of the benzene rings is 50.34 (12)°. The pyran rings adopt half-chair conformations. The ...

This work was carried out in orchards of guava progenies, and loquat and peach cultivars, in Monte Alegre do Sul, SP, Brazil, in 2002 and 2003. Guavas and loquats were bagged and unbagged bi-weekly and weekly, respectively, for assessment of the infestation period. Peach was only bagged weekly. The assays started when the fruits were at the beginning of development, but still green. Ripe fruits...

While it has become increasingly clear that multicellular organisms often harbor microbial symbionts that protect their hosts against natural enemies, the mechanistic underpinnings underlying most defensive symbioses are largely unknown. Spiroplasma bacteria are widespread associates of terrestrial arthropods, and include strains that protect diverse Drosophila flies against parasitic wasps and...
