Luminescent properties of heterotrinuclear 3d-4f complexes constructed from a naphthalenediol-based acyclic bis(salamo)-type ligand.

Heterotrinuclear 3d-4f complexes with a naphthalenediol-based acyclic bis(salamo)-type ligand have been synthesized and structurally characterized. Spectral titrations clearly show that the heterotrinuclear complexes [Zn(L)La(OAc)] (1), [Zn(L)Ce(OAc)] (2) and [Zn(L)Dy(OAc)(CHOH)]·CHCl (3) are acquired by the substitution reaction of the obtained homotrinuclear Zn(II) complex with 1 equiv. of Ln(NO) (Ln=La, Ce and Dy).

Research on the practical parameters of sex pheromone traps for the oriental fruit moth.

Background: The oriental fruit moth (OFM) is a worldwide fruit-boring insect pest. In China, OFM monitoring traps use a sex pheromone lure, but their overall design is varied. As such, there is a critical need to develop a standardised OFM trap design.

[Ecological-geographic landscapes of natural plague foci in China VII. Typing of natural plague foci].

Objective: To group and characterize natural plague foci in China.

Methods: A novel two-class typing method as well as a three-indication nomenclature method were established to group and characterize the natural plague foci, on the basis of eco-geographical landscapes of plague foci, genetics of Yersinia pestis, zoology of rodent reservoirs and the entomology of flea vectors.

Results: A total of 12 distinct natural plague foci (including 19 subtypes) as well as their biological features were characterized.

[Ecological-geographic landscapes of natural plague foci in China VI. Biological characteristics of natural vectors of Yesinia pestis].

Objective: To characterize the biological characteristics of natural vectors of Yersinia (Y.) pestis in China.

Methods: Species and genera of natural vectors of Y.
