The ecology of solitary bees
TLDR
The development of management procedures which will permit increased utilization of native solitary bees and perhaps lead to the importation of foreign species native to the areas in which the authors' agricultural crops originated, requires a detailed knowledge of the ecology, or environmental relationships, of these bees.
SQUASH AND GOURD BEES (PEPONAPIS, XENOGLOSSA) AND THE ORIGIN OF THE CULTIVATED CUCURBITA
TLDR
Although the large, conspicuous and ultra-violet reflective flowers attract a wide variety of bees and other anthophilous insects for nectar, pollen or both, only the squash and gourd bees derive virtually their entire economy from the nectar and pollen of these plants.
Methods and Principles of Systematic Zoology

Methods and principles of systematic zoology are presented as well as methods and principles for quantitative and qualitative characterization of infectious disease.

TLDR
It is established that more than 400 species of native bees visit the flowers of Helianthus in America north of Mexico and of these it is those species that have evolved a specialized intrafloral relationship with these flowers that serve as the principal pollinators of these plants.
Ecology of the squash and gourd bee, Peponapis pruinosa, on cultivated cucurbits in California (Hymenoptera: Apoidea)
TLDR
This investigation focuses primarily on those ecological aspects involved in the natural history of the squash and gourd bee, Peponapis pruinosa, as it occurs in commercial squash and pumpkin plantings of the Sacramento Valley of Calitornia.
