SummaryOne aspect of behavioral ecology that has received considerable attention, especially by students of social insects, is the relative amount of energy invested by parents in the rearing of male versus female offspring. Sexual selection theory makes predictions about how individuals should allocate their total investment in the sexes. To test these predictions we must accurately quantify the relative “cost” incurred by a parent in the production of an average individual of either sex. Body… 
Optimal resource allocation, maternal investment, and body size in a solitary bee, Osmia bicornis
Resources (energy expenses) that can be devoted to progeny are always limited. Optimal resource allocation theory predicts that parents should allocate resources to their offspring in portions that

It is suggested that the production of small males (minors) is the result of active female control rather than the product of food shortages that force females to undersupply some brood cells, making it difficult to compare the relative costs of minors and majors in terms of maternal time investments.
Sociodemographic variation in foraging behavior and the adaptive significance of worker production in the facultatively social small carpenter bee, Ceratina calcarata
The parental investment strategies of a subsocial small carpenter bee are characterized and the potential adaptive significance of prolonged maternal care and worker production in this species is revealed.
A day in the life of an oil bee: phenology, nesting, and foraging behavior
A population of the oil bee is established in a flight cage and the emergence phenology, sex ratio, nesting behavior, and foraging behavior of individually marked bees are recorded to provide new insights into the bionomics of bees.
The biology of the primitively eusocial Augochloropsis iris (Schrottky, 1902) (Hymenoptera, Halictidae)
The resultant sex ratio of the third brood suggests that the third-phase workers of eusocial nests are at least in partial control of their colony's sex ratios, in cases where the queens mated only once.
Annual and Social Variation in Foraging Effort of the Obligately Eusocial Sweat Bee, Halictus ligatus (Hymenoptera: Halictidae)
Observations of foraging effort show that the relatively large queens of 1990 spent about as much time foraging as the relatively small queens of 1991, and still produced much smaller brood, which suggests that a previously unsuspected effect of the poor weather in 1990 colonies was a scarcity of pollen, at least during the queen foraging period.
Relatedness and sex ratio in a primitively eusocial halictine bee
The study species is the most weakly eusocial hymenopteran for which relatedness estimates and sex ratio data are available and this study suggests the importance of indirect fitness contributions in the early stages of social evolution.
Born to be bee, fed to be worker? The caste system of a primitively eusocial insect
The marked size dimorphism between females produced in the first and second brood and the consistently smaller pollen provisions provided to the first brood suggest that theFirst brood females are channelled into a helper role during their pre-imaginal development.
Nest and Provisioning Biology of the Bee Panurginus polytrichus Cockerell (Hymenoptera: Andrenidae), with a Description of a New Holcopasites Species (Hymenoptera: Apidae), Its Probable Nest Parasite

The nest architecture, mating behavior and nest provisioning biology of Panurginus polytrichus in central Texas are described and a possible biological link with the Old World ammobatoidine bees is suggested.


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.
Alternation of sex ratio in a partially bivoltine bee, Megachile rotundata (Hymenoptera: Megachilidae)
Data on offspring production by the alfalfa leafcutting bee, Megachile rotundata, from three site-years were used to examine predictions of parental investment and sex ratio theory and the import of the unexpected finding that diapausing progeny are 50% larger than summer-emergent progeny is discussed.
Sex Ratios, Parent-Offspring Conflict, and Local Competition for Mates in the Social Wasps Polistes metricus and Polistes variatus
The prediction implicit in Fisher's theory that the remaining population will exhibit a female-biased PI ratio bringing the population investment ratio to 1:1 is met and no local competition for mates is inferred to have occurred based on the observation of no inbreeding and viscosity of the female portion of the population.
On the size determination of bumble bee castes (Hymenoptera: Apidae)
Female larvae of Bombus rufocinctus Cresson, a 'pollen-storing' species showing well-marked intercaste size dimorphism, were hand reared on a diet of pollen, honey, and water from the penultimate larval instar until adulthood, suggesting a simple biophysical explanation for the determination of caste-specific body size.

It is suggested that worker care of the brood may be the most important determinant of brood production, and thus food may not be a direct limiting resource in harvester ants.
Nesting Behavior of Four Species of Perdita (Hymenoptera: Andrenidae)
Observations on a nesting aggregation of Perdita (Perdita) difficilis in south eastern Arizona indicate that this species is solitary, provisions two cells per day during two foraging periods

SummaryFemales of the solitary eumenid wasps Ancistrocerus adiabatus and Euodynerus foraminatus control the adult size of their offspring by the amount of food provded to the larvae. For both
It is concluded that variability among females in investment patterns and variability in size among progenies are probably maintained by such factors as resource heterogeneity and the shape of the adult survivorship curve.
Temporal variability in the sex ratio of a non-social bee, Osmia liqnaria propinqua Cresson: Extrinsic determination or the tracking of an optimum?
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.
