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......
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 ......
Scientific note: colony losses survey in Turkey and causes of bee deaths
Apidologie - Tập 41 - Trang 451-453 - 2010
The effects of four crop protection products on the morphology and ultrastructure of the hypopharyngeal gland of the European honeybee, Apis mellifera
Apidologie - - 2011
This study describes the impact of sublethal doses of 4 pesticides on size and morphology of the honeybee worker’s hypopharyngeal glands. This gland plays an essential role in brood care by young workers, and thus colony growth. Contaminating 7 day old caged bees, we sampled after 1 day and 1 week for Captan-, Imidacloprid- and Indoxacarb-treated bees and after 1, 2, 3, 4, 5 and 7 days for Fenoxyc......
The development of HopGuard® as a winter treatment against Varroa destructor in colonies of Apis mellifera
Apidologie - Tập 46 - Trang 748-759 - 2015
The development of new veterinary medicinal products to control Varroa destructor is very important for the successful management of honey bee colonies. We tested natural plant compounds (hop acids) as active ingredients for a new veterinary drug for Varroa control. Tolerability of bees and efficacy against mites was tested in the laboratory and in the field. In laboratory tests, hop beta acids we......
Stingless bee honey (Hymenoptera, Apidae, Meliponini): a review of quality control, chemical profile, and biological potential
Apidologie - Tập 52 - Trang 113-132 - 2021
Products made by bees are well-known for their beneficial properties and nutritional value. This association has been proven by scientific studies that describe their composition and biological activities. The aim of this study is to portray the state of the art on research regarding stingless bee honey. The search for standards that guide the trade of these products is still portrayed as a future......
Composition of volatiles from fermenting pollen dough and attractiveness to the small hive beetle Aethina tumida, a parasite of the honeybee Apis mellifera
Apidologie - Tập 38 - Trang 380-389 - 2007
The response of the small hive beetle (SHB), Aethina tumida Murray, to volatiles from a pollen-based diet conditioned by the feeding of 100 adult virgin female or male SHBs (4–8 weeks old) for 1, 3, 7 or 14 days is described and compared to that of the same diet inoculated with the yeast Kodamaea ohmeri (NRRL Y-30722), isolated from the beetle. In a wind tunnel, volatiles from pollen dough conditi......
Scientific note: mass-nesting of a native bee Hylaeus (Euprosopoides) ruficeps kalamundae (Cockerell, 1915) (Hymenoptera: Colletidae: Hylaeinae) in polystyrene
Apidologie - Tập 51 - Trang 107-111 - 2019
Plastic is pervasive across ecosystems, with polystyrene being a common plastic synthetic material used in buildings. Although polystyrene is used in hive construction for European honeybees and managed megachilids, cavity-nesting colletids have never been documented to nest in such materials. Here, observations of the solitary native bee Hylaeus (Euprosopoides) ruficeps kalamundae mass-nesting in......
