The Ethology Of The Wasp, Pseudomasaris Edwardsii (Cresson), And A Description Of Its Immature Forms (Hymenoptera: Vespoidea, Masaridae), Phillip F. Torchio
All PIRU Publications
In a greenhouse, each nest of Pseudomasaris edwardsii (Cresson) was constructed of nectar-moistened soil, was solitary and was placed in open but concealed niches attached to a variety of substrates. The wasp anchored her egg by its posterior tip to the bottom of the cell, deposited a jellylike cylindrical provision composed of Phacelia pollen and nectar and constructed a cell cap. Soil carried to the nest was attached to the post genal surfaces of the female's head, and the pollen and nectar were transported in her honey stomach. Cells were clustered and attached to each other and to the substrate …

Selective Breeding Of Honeybees For Alfalfa Pollen: Fifth Generation And Backcrosses, William P. Nye, Otto Mackensen
Selective Breeding Of Honeybees For Alfalfa Pollen: Fifth Generation And Backcrosses, William P. Nye, Otto Mackensen
All PIRU Publications
Selection within lines for honeybees showing strong and weak tendencies toward collection of alfalfa pollen was continued through the fifth generation. In the line with a strong tendency (high line), the average percentage of pollen collectors collecting alfalfa pollen increased from 66% in the fourth generation to 85% in the fifth. In the line with the weak tendency (low line), the corresponding percentages were 8% and 18 %. Backcrosses of the two lines resulted in an intermediate mean. At Howell, Utah, where other pollen than alfalfa was scarce, the percentages were 99% and 53% for the high and low lines …
