Abstract. 1. The phenotypic variability of several estimates of fitness among seventeen nesting female O.lignaria Cresson was examined in a glasshouse provided with abundant resources. 

Optimal progeny body size in a solitary bee, Osmia bicornis (Apoidea: Megachilidae)

1. Females of solitary, nest‐constructing bees determine both sex (haplo‐diploidy) as well as body size (by amount of provision) of each single offspring.

The nectar alkaloid, gelsemine, does not affect offspring performance of a native solitary bee, Osmia lignaria (Megachilidae)

TLDR
The ecology and evolution of foliar‐feeding insects are thought to be closely tied to plant secondary compounds, which are also abundant in floral nectar, and their role in mediating pollinator preference and performance remains relatively unexplored.

RAPID COMMUNICATION HERITABILITY FOR SIZE IN THE MEGACHILID BEE OSMIA LIGNARIA PROPINQUA CRESSON

TLDR
Because of the low heritability for size among females, it is concluded that a selective breeding program to increase size in this bee of potential commercial importance would be unprofitable.

Agricultural land use yields reduced foraging efficiency and unviable offspring in the wild bee Ceratina calcarata

TLDR
Habitat changes marked by decreasing availability of nesting sites and flower resources for pollinators and their effect on wild bee maternal body size and foraging effort and whether there is a subsequent effect on their offspring are studied.

Effects of forest loss and fragmentation on pollen diets and provision mass of the mason bee, Osmia cornifrons, in central Japan

TLDR
Habitat loss and fragmentation potentially affect the performance of bees that forage nectar and pollen of plants in their habitats, which seem to provide more floral resources for bees than do the plantations.

Management of Osmia lignaria (Hymenoptera: Megachilidae) Populations for Almond Pollination: Methods to Advance Bee Emergence

TLDR
Temperature treatments that promoted rapid immature development, and thus longer wintering periods, resulted in earlier spring emergence patterns of bees well timed with bloom period of almonds, and warmerWintering periods also resulted inEarlier emergence.

Influence of Rough Handling on Osmia lignaria (Hymenoptera: Megachilidae) Nest Establishment in Commercial Orchards

TLDR
There was no significant difference in the proportion of shaken and unshaken females that nested, indicating that rough handling of overwintering bees does not discourage nest establishment.

WINTER MANAGEMENT OPTIONS FOR THE ORCHARD POLLINATOR OSMIA LIGNARIA SAY ( HYMENOPTERA : MEGACHILIDAE ) IN NOVA SCOTIA

J. ent. Soc. Ont. 139: 3–18 The Blue Orchard Bee, Osmia lignaria Say, a commercially available solitary bee, was recently introduced into the Annapolis Valley of Nova Scotia for assessment as a

Influence of resource level on maternal investment in a leaf-cutter bee (Hymenoptera: Megachilidae)

TLDR
A multifaceted parental investment model based on the underlying assumption that individual females determine their sex investment according to resource availability and oocyte availability to maximize reproductive success predicts that greater availability of resources used for provisions will lead to an increase in the proportion of females produced.

Phenotypic Variation in Fitness Traits of a Managed Solitary Bee, Osmia ribifloris (Hymenoptera: Megachilidae)

TLDR
These results, taken together, confirm that adult O. ribifloris from all trap-nest sites are genetically compatible, but some phenotypic variation exists that could affect this species performance as a commercial blueberry pollinator.

Nesting behavior of Osmia lignaria propinqua Cresson (Hymenoptera: Megachilidae)

TLDR
Osmia lignaria propinqua Cresson, a gregarious solitary-nesting bee native to the western United States, is a potential pollinator of orchards in the Pacific Northwest since it readily accepts man-made nesting materials and normally nests during the time fruit is blooming.

The Life-History of Osmia Lignaria and O. Cordata, with Notes on O. Conjuncta

TLDR
There is diversity in the habits of the two species, however, in the kind of materials which they gather for partitions and plugs, for O. lignaria confines her choice to mud while O. cordata uses a leaf-paste.

IMPROVEMENT OF THE SEX-RATIO OF A PARASITE BY SELECTION

It is a well known fact, noticed by many workers engaged in breeding hymenopterous parasites, that there is a tendency in many bisexual species for the sex-ratio to decrease as the breeding work

Sex Ratio of Parental Investment in Colonies of the Social Wasp Polistes fuscatus.

Field estimates of parental investment in the two sexes in the social paper wasp Polistes fuscatus indicate that the mother's interests, rather than those of her worker offspring, are realized. Local

SEX RATIO, BODY SIZE AND SEASONALITY IN A SOLITARY BEE, OSMIA LIGNARIA PROPINQUA CRESSON (HYMENOPTERA: MEGACHILIDAE)

TLDR
This study is, in part, an empirical test of sex ratio theory using a solitary bee, Osmia lignaria propinqua Cresson, to test the accuracy of theoretical formulations and document seasonal variability in the sex ratio.

Temporal variability in the sex ratio of a non-social bee, Osmia liqnaria propinqua Cresson: Extrinsic determination or the tracking of an optimum?

TLDR
The sex ratio at all sites changed from a significant male bias in 1973 to a significant female bias in 1975 and subsequently returned to the area of equilibrium and the results are most reasonably interpreted as support for Fisher's theory of an equilibrium sex ratio.

Nesting Behavior of Megachile rotundata (Hymenoptera: Megachilidae) Monitored with an Event Recorder

TLDR
Each phase of nesting activity, nest construction, provisioning, and oviposition, resulted in a distinct pattern on the recording chart of the alfalfa leafcutter bee, Megachile rotundata, regulated by both temperature and light intensity.

The influence of maternal physiology on the incidence of diapause

TLDR
During the study of the biology of two hymenopterous parasites, it was found that the age of the parent female when an egg was laid had some influence on the tendencies of the larval progeny to enter diapause.
