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, worker survival, brood size and larval development. Two doses were used: D1 = 10 µg AI kg−1 in syrup and 6 µg AI kg−1 in pollen; D2 was 2.5 times high...

... genome compared with other insect species such as flies and mosquitoes (Claudianos et al., 2006). While some review studies have compared the relative sensitivity of A. mellifera spp. to other bees (Arena and Sgolastra, 2014;Tasei et al., 2000) and insect species (Hardstone and Scott, 2010), quantitative comparisons of differences in sensitivity, especially using the same experimental approaches are lacking (but see (Scott-Dupree et al., 2009)). In addition, most of the 'standard' tests conducted to date tend to be of short duration (48-96 h, e.g. ...
... This biological mechanism involves pulling live larvae out of cells and depositing them outside of the nest, which can control the number of larvae within the brood. This behavior is not well studied but appears to occur when the colony is under stress such as resource deficiency (i.e., stress response) [28][29][30][31]. Another stress response was evaluated through pollen efficiency (i.e., the mass of hatched offspring divided by the mass of collected pollen per microcolony), which highlights when workers need to collect more pollen to produce offspring, and could then be indicative of a resource allocation constraint by directing energy to immune responses. ...
