Improvement of artificial feeding in a standard in vitro method for rearing Apis mellifera larvae
An in vitro method for rearing bee larvae has been improved by studying three parameters of feeding: 1- the mode of feeding, 2- the amount of diet per larva, 3- the diet composition according to theExpand

Nutritive value of 15 single pollens and pollen mixes tested on larvae produced by bumblebee workers (Bombus terrestris, Hymenoptera: Apidae)
AbstractLaboratory trials were performed at 27 °C on micro-colonies comprised of three Bombus terrestris workers. They were fed with syrup and pollen paste ad libitum. The micro-colonies wereExpand

Toxicity of dimethoate and fenoxycarb to honey bee brood (Apis mellifera), using a new in vitro standardized feeding method.
A new in vitro method was devised to assess the effects of pesticides on honey bee brood. The method allowed the quantification of doses ingested by larvae and the assessment of larval and pupalExpand

Sub‐lethal effects of imidacloprid on bumblebees, Bombus terrestris (Hymenoptera: Apidae), during a laboratory feeding test
A laboratory feeding test was conducted on queenless micro-colonies of three bumblebee workers (Bombus terrestris L) to study the effects of low doses of imidacloprid on pollen and syrup consumption,Expand

Relationship between aging, mating and sperm production in captive Bombus terrestris
SUMMARYMating behaviour of Bombus terrestris, its sperm production and sperm transfer to queens were studied in parallel, under controlled conditions. The mean value of the age of mating was 6.1 daysExpand

Territorial biodiversity and consequences on physico-chemical characteristics of pollen collected by honey bee colonies
Pollen resources may become a constraint for the honey bee in cereal farming agrosystems and thus influence honey bee colony development. This survey intended to increase knowledge on bee ecology inExpand

Validation of a Method Using Queenless Bombus terrestris Micro-Colonies for Testing the Nutritive Value of Commercial Pollen Mixes by Comparison with Queenright Colonies
Abstract The nutritive value of pollen blends purchased by bumble bee producers from beekeepers is a key factor of successful mass rearing. We have already devised a method for quality ranking ofExpand

Honey bee brood ring-test: method for testing pesticide toxicity on honeybee brood in laboratory conditions
contribution to session IV Test methodology The Experimental unit of entomology (INRA, France) developed a new in vitro method to assess effects of pesticides on honey bee larvae. The methodExpand

Hazards of Imidacloprid Seed Coating to Bombus terrestris (Hymenoptera: Apidae) When Applied to Sunflower
Abstract Seed coating treatments of sunflower by the systemic insecticide imidacloprid was suspected of affecting honey bees and bumblebees. The hypothesis raised was whether imidacloprid couldExpand
