“…Temperatures during all tests (including those outdoors) were 22 ± 2°C for O. lignaria and 25 ± 2°C for M. rotundata and A. mellifera. We used a lower temperature for O. lignaria because this spring-flying bee is active at lower temperatures than M. rotundata or A. mellifera (Burril and Dietz, 1981;Lerer et al, 1982;Bosch and Kemp, 2001). …”

-We devised a simple method ("flower") to feed bees individually, and compared it with two other methods commonly used ("film canister" and "glass vial"). We tested the three methods on two solitary species, Osmia lignaria and Megachile rotundata, and one social species, Apis mellifera, under four different light regimes (natural, artificial, plant growth and darkness). The flower method was the most effective for all three bee species: 90-95% of the bees fed under natural light, 80-95% under artificial light, 75-100% under plant growth light, and 45-70% in darkness. Percent success was 0-50% with the film canister method, and 0-60% with the glass vial method. The flower method may allow more comprehensive future evaluation of pesticide effects on bees. oral toxicity test / individual feeding / Osmia lignaria / Apis mellifera / Megachile rotundata

“…Osgood [52] and Lerer [53] suggested that the foraging activities of the stingless bee Trigona hyalinata begin in the morning by temperature influence, and in the end of the day, there is luminosity influence. It is important to point out that our observations were accomplished until 4 p.m., a period with a great luminosity in the most part of the year, and this might have had an effect on the lack of influence of this variable on the foraging.…”

Foraging behavior in social wasps is important in the development of the colony and reflects an important ecological interaction between the colony and the environment. Although the social traits of the colony play a role in the foraging activities, the conditions that establish the space and time limits are mainly physical. Here, we evaluate colonies of Polybia paulista throughout one year in order to verify the foraging activities and the items collected, as well as the importance of temperature, relative humidity, and solar radiation on motivating foraging. Collection of liquids was always higher than that of solids; preys were collected all year long, and nests showed two annual episodic expansions. The linear mixed effects (LME) model used to analyze which weather factors influence the foraging showed temperature as the most influencing factor on the collection of materials.

“…Differences between individual plants in the taxonomic composition of pollinator assemblages may be due to variation in phenotypic features (e.g., floral morphology, nectar abundance, size of floral display), but also to factors unrelated to their phenotypes, such as environmental variables that depend on their particular location in the habitat. Microclimatic variables (e.g., solar irradiance, humidity, ambient temperature) are known to influence pollinator activity and behavior at flowers (Lundberg 1980, Lerer et al 1982, Willmer 1983, Stone et al 1988, Stanton and Galen 1989, Herrera 1995a, and different pollinators may respond differentially to variation in the physical environment (Gilbert 1985, Herrera 1990a). The following questions will be specifically addressed: (I) DoL.…”

Variation in pollinator composition at the individual plant level is an important prerequisite for plant specialization on pollinators that does not seem to have been investigated previously. I studied variation in pollinator composition in a southeastern Spanish population of the insect-pollinated shrub Lavandula latifolia (Labiatae) and examined its correlates, with particular reference to the distinction between factors intrinsic (flower morphology, nectar standing crop, size of floral display) and extrinsic (sunlight regime, ambient temperature, humidity) to the plants. L. latifolia shrubs differed significantly in all intrinsic variables measured, in average irradiance levels (due to site-dependent variation in timing and duration of insolation periods), and in pollinator composition at both the species and order levels. Individual variation in pollinator composition was largely due to differences among insect taxa in their foraging responses to the sunlight mosaic. While some pollinators foraged indiscriminately over that mosaic, others preferred sites characterized by high irradiance. Variation among plants in intrinsic variables was unrelated to differences in pollinator composition, which depended significantly only on the sunlight regime associated with each plant's location in the habitat. Site-specific effects in pollination will generally act to reduce the likelihood of selective pressures by animals on plant traits. Their importance should be greatest in habitats characterized by patchiness in environmental variables that affect pollinator behavior and in plants with pollinator assemblages dominated by ectothermic species.
