Abiotic correlates of bee diversity and composition along eastern Neotropics
Apidologie - Tập 44 - Trang 547-562 - 2013
Native bee diversity is poorly documented for many regions of the globe, particularly in the Neotropics. The available structured inventories in this biogeographical region provide reliable data, but they lack a comprehensive interpretation due to the absence of an effort to relate diversity and composition data with environmental variables. We aimed to answer the following questions: (1) Do abiot......
Effects of field characteristics on abundance of bumblebees (Bombus spp.) and seed yield in red clover fields
Apidologie - Tập 41 - Trang 657-666 - 2010
Red clover is a key floral ressource for bumblebees (Bombus spp.). We here investigate variation within and among red clover fields in species richness and abundance of Bombus spp. in addition to Apis mellifera. Bumblebee individuals were grouped into the following functional groups, based on castes and tongue length: (1) all queens, (2) all workers, (3) short-tongued workers and (4) long-tongued ......
Bioactivity of gallic acid–conjugated silica nanoparticles against Paenibacillus larvae and their host, Apis mellifera honeybee
Apidologie - Tập 50 - Trang 616-631 - 2019
The aim of this work was to evaluate antimicrobial activity against Paenibacillus larvae and oral toxicity against workers and larvae of Apis mellifera of gallic acid (GA) and two nanohybrids of GA and silica. Also, the physicochemical, structural, and energetic properties of GA and the nanohybrids were determined through structure–activity relationship (SAR). The minimum inhibitory concentration ......
Bee colony losses in Brazil: a 5-year online survey
Apidologie - Tập 50 - Trang 263-272 - 2019
In 2014, an online survey was launched to assess impacts of bee losses in Brazil (honeybees, stingless bees, and solitary bees). Events from January 2013 to December 2017 were collected on a website

Variation in maternal solitary bee nest defence related to nest state
Apidologie - Tập 47 - Trang 90-100 - 2015
Parental protection of offspring is found in numerous animal species. Protection provides offspring with a greater chance of surviving to be able to reproduce, while at the same time, often posing a cost to the parent. Therefore, the net value of defence for the parent can vary depending on the developmental stage of the offspring and their ability to defend themselves. For example, in commonly st......
A mathematical model of anarchy in bees
Apidologie - Tập 51 - Trang 1117-1124 - 2020
Functional worker sterility in queenright honey bees (Apis mellifera) is fostered by the colony-level costs of this behavior. However, anarchy in the beehive can occur when a fraction of workers lay eggs, which, if reared, will develop into males (drones). Because males do not gather resources but still consume them, they represent an additional energic cost for the colony. This small number of an......
Mating behaviour of the large-head resin bee Heriades truncorum (Megachilidae: Osminii) suggests female plastic strategy in selection of a mating partner and male quality assessment
Apidologie - - 2022
Behavioural courtship display and size of males are two attributes often used by females to select a mating partner. According to sexual selection, such traits are of importance, because a bigger size male or males displaying a better courtship could enhance the possibility of females to transmit her genes to the following generations via her offspring. In Hymenoptera such as in solitary bees, it ......
Genome-wide SNPs show hybridization of Varroa mites from different Apis hosts in Vietnam and Taiwan
Apidologie - Tập 54 - Trang 1-15 - 2023
Varroa destructor, an ectoparasite of Apis cerana (the Eastern honeybee), has attained global notoriety following the decimation caused by its host shift to Apis mellifera. Previous studies indicated that Varroa mites have geographic and host-specific mitochondrial haplotypes (mitotypes) in A. mellifera colonies, suggesting that only a few genetic strains (i.e., Korean and Japanese mitotypes) can ......
Scientific note: colony losses survey in Turkey and causes of bee deaths

Patriline-level variability in olfactory learning in the honey bee
Apidologie - Tập 41 - Trang 436-442 - 2010
Genetically determined differences among honeybee workers are known to contribute to task specialisation. To investigate the genetic component of olfactory learning we used proboscis extension conditioning to record individual performance, and a patriline-level analysis to separate the variance in learning performance into its different components. We found that the among-patriline within-colony c......
