Comparative molecular cytogenetics in Melipona Illiger species (Hymenoptera, Apidae)
Cytogenetic studies in Melipona are scarce with only 24 species analyzed cytogenetically. Of these, six species had the rDNA sites physically mapped and characterized by Fluorescent in situ Hybridization (fish).

Diaryl-furanones are specific analytical reagents for the biochemical detection of primary amines by fluorescence techniques. Well-known reagents are fluorescamine (Fluram) and 2-methoxy-2,4-diphenyl-3(2H)-furanone (MDPF), yielding fluorescent products ...

DIRECT FLUOROCHROMING OF RICKETTSIAE [PDF]
Several fluorochromes were used to stains directly R. mooseri in smears and tissues. The effects of fixatives, hydrogen ion concentration, time in stain and concentration of stain were studied also. Interference by background fluoresence was minimized by a preliminary staining of fixed preparations with an alcian blue, periodic acid-Schiff sequence ...

The chromosome number and heterochromatin distribution pattern suggest differentiation among species of the Stylosanthes scabra-seabrana complex [PDF]
The genus Stylosanthes has economic importance in semi-arid regions and requires studies that reveal complex relationships between species involving different ploidies.

The species of Anastrepha are arranged into 17 intrageneric groups. Recently, it was proposed that two species of the striata group, Anastrepha striata and A. bistrigata, might be realocated to serpentina group. Anastrepha bistrigata and A.
