In a field experiment, we tested whether workers of bumblebees, Bombus pascuorum and B. humilis, parasitized by larvae of conopid flies, Physocephala rufipes and Sicus ferrugineus, differ in their flower choice from unparasitized ones. We collected workers at random in the field and immediately tested them in experimental arenas that offered the choice of a reference plant (red clover, Trifolium pratense) versus a test plant (from five species). The choices of 396 workers were analysed with… Expand
Effects of parasitic mites and protozoa on the flower constancy and foraging rate of bumble bees
TLDR
This study is the first to investigate the effects of parasitic protozoa and tracheal mites on the foraging behavior of bumble bees, and provides the first report of Crithidia bombi in commercial bumble bee colonies in North America. Expand
Patterns of parasite infection in bumble bees (Bombus spp.) of Northern Virginia
TLDR
A season‐long survey of bumble bees in seven grassland meadows of the northern Shenandoah Valley and Piedmont regions in Virginia was conducted in 2011 to ascertain the local prevalence and predictors of parasitism by the internal parasites Nosema and Crithidia, and by parasitoid conopid flies. Expand
Does parasitic infection impair the ability of bumblebees to learn flower-handling techniques?
TLDR
Results indicate that C. bombi can influence the foraging behaviour of host bumblebees in subtle but ecologically significant ways. Expand
Chronic exposure to a neonicotinoid pesticide alters the interactions between bumblebees and wild plants
TLDR
It is suggested that the foraging behaviour of bumblebees on real flowers can be altered by sublethal exposure to field‐realistic levels of pesticide, which has implications for the foragers' success and persistence, but perhaps more importantly for the interactions between wild plants and flower‐visiting insects.

Flying with the enemy: An endoparasitic fly larva in Brazilian bumblebees
TLDR
In forest fragments at southeast of Brazil (Sorocaba City, Sao Paulo State) tachinid fly larvae were found inside the abdomen of foraging females of Bombus morio and  Bombus atratus, the first time that the occurrence of such parasitism is described for these species. Expand
Correlates of rarity in UK bumblebee (Bombus spp.) populations
TLDR
The data presented here emphasise the challenges of studying fitness in wild populations, and underline the requirement for research into the fundamental principles underlying many assumptions made by conservation genetic theory. Expand
Prevalence of the parasite Strepsiptera in adult Polistes wasps: field collections and literature overview
TLDR
The incidence of strepsipteran parasites in temperate Polistes wasps is recorded following the collection and dissection of adults from nests, foraging sites and hibernacula, with results indicating that wasps which were captured when hunting for prey or collecting water were rarely parasitized. Expand
Title : COLOUR PREFERENCES IN RELATION TO THE FORAGING PERFORMANCE AND FITNESS OF THE BUMBLEBEE Bombus Terrestris
Bumblebee (Bombus terrestris) colonies showed significant variation in their unlearned preference for violet (bee UV-blue) over blue (bee blue) flowers. Bumblebee colonies with a higher averageExpand
On the evolutionary ecology of host–parasite interactions: addressing the question with regard to bumblebees and their parasites
TLDR
Using bumblebees, Bombus spp, and their parasites as a model system, answers to questions about how genetics affects host–parasite interactions are found and the unexpected discovery of novel phenomena concerning, for instance, female mating strategies is found. Expand
Diversity of Nosema associated with bumblebees (Bombus spp.) from China.
TLDR
The results showed that 62 individuals representing 12 Bombus spp. Expand

Resource Partitioning in Bumblebees: Experimental Studies of Foraging Behavior
TLDR
These removal experiments demonstrated that the bumblebees were sampling flowers frequently enough and were flexible enough in the absence of other bumblebee species. Expand
Larval development of two parasitic flies (Conopidae) in the common host Bombus pascuorum
TLDR
The estimates for developmental times and the patterns found in this study suggest that conopid larvae seem capable of physical attacks, particularly during the first instar, when elimination of competitors is most common, and that S.ferrugineus has a time advantage because of its faster early development.

Parasites, floral resources and reproduction in natural populations of bumblebees
Weekly censures of bee abundance, flower availability, resource use and infestation of bees by parasitic flies (Conopidae, Diptera) were made throughout a seasonal cycle in eight populations each ofExpand
Exploitation of cold temperature as defence against parasitoids in bumblebees
TLDR
It is demonstrated that parasitized workers of the bumblebee Bombus terrestris L. stay in the field overnight rather than returning to their nest, which retards the development of the parasite and reduces the chances of successful development, and enhances colony success by prolonging the life of Parasitized workers while at the same time reducing parasitoid fitness.

Heterothermia in Foraging Workers and Drones of the Bumblebee Bombus terricola
TLDR
By maintaining a high TTh and flight readiness, workers can "gamble" on the chance of finding a new food source, unlike drones who do not have the hive's energy resources to fall back on if they deplete their supply of stored fuel. Expand
THE FORAGING SPECIALIZATIONS OF INDIVIDUAL BUMBLEBEES
TLDR
The foraging behavior of bumblebees is discussed from a comparative standpoint with other bees and in relation to food distribution and availability in the environment. Expand
Structure in seven bumblebee communities in eastern Finland in relation to resource availability
TLDR
Data suggest that species with similar proboscis tend to co-occur on fields with availability of appropriate corolla tubes, and a positive correlation was found when the structure of bumblebee communities and of floral resources was expressed in terms of diversity of Proboscis lengths and corolla tube depths. Expand
Species Structure of Bumblebee Communities in North America and Europe
TLDR
The competitive exclusion principle states that two species cannot coexist on the same limiting resource, but the fact that bumblebees are annual species, while many of the plants they visit are long-lived perennials, lends support to this interpretation. Expand
"Majoring" and "Minoring" by Foraging Bumblebees, Bombus Vagans: An Experimental Analysis
TLDR
It is concluded that the most important problem faced by the foraging bees attempting to enhance food intake is that of assessing the resources, which often change rapidly. Expand
Costs and Benefits of Behavioral Fever in Melanoplus sanguinipes Infected by Nosema acridophagus
TLDR
This investigation is the first to show that protozoal infections can generate fever in an ectotherm, the costs of fever involve decreased growth rate of the host, and a net benefit of fever occurs when the pathogen is introduced to the host by a natural route. Expand
