RAPD analyses were performed on five geographically isolated populations of Megachile rotundata. We used haploid males of the alfalfa leaf-cutting bee, M. rotundata, to overcome the limitation of the dominance of RAPD markers in the determination of

The within-field drifting of Megachile rotundata (Fab.) females was evaluated at three field sites in Saskatchewan and one site in Alberta, Canada. Marked females were released at field shelters and bee movement was monitored throughout the field sea

The 2-μm plasmid of industrial and laboratory strains of Saccharomyces cerevisiae exists as two main polymorphic forms designated type I and type II. Polymorphism is restricted to the 3200-bp right unique region where types I and II show approximate

Seven strains of bakers' yeast were obtained as a representative sample of the Spanish baking industry. The nuclear genome was monitored for polymorphism by transverse alternating field electrophoresis (TAFE) and restriction maps of 2 micron DNA were

2 microns DNA isolated from industrial Saccharomyces cerevisiae yeasts exhibited extensive restriction fragment length polymorphisms. At least five 2 microns species were identified from eleven [cir+] strains. Southern hybridization mapped restrictio

Mutant regulatory loci of the branched pathway for the biosynthesis of isoleucine–valine and leucine were identified with the unusual phenotype of an amino acid dependent auxotrophy. Two mutant loci, bcs1 and bcs2, conferred branched chain amino ac

A French univoltine and a Canadian partially bivoltine strain of the alfalfa leafcutting bee were field tested near Ontario, Oregon. Prepupae were sampled on July 31 and Aug. 27. On both dates the univoltine strain showed a higher % of healthy prepup

Diapause development of a partially bivoltine and univoltine strain of Megachile rotundata (Fab.) was investigated prior to normal field harvest. A 12 h alternating temperature of 10–30°C during pre-harvest storage resulted in diapause development
