Dominance hierarchy and reproductive conflicts among subordinates in a monogynous queenless ant.
Nests, worker population, and reproductive status of workers, in the giant queenless ponerine ant Dinoponera Roger Hymenoptera Formicidae.
Key words: bumble bee, Bombus atratus, queenless colonies, survivorship curves, life table.
In addition to interspecific variation of longevity of bumble bee workers, some studies have showed that factors such as activities performed in the colony (Garofalo 1978, Katayama 1996), forage availability and phases in the colony development (Goldblat and Fell 1987) and colony conditions, if queenright or queenless colony (Katayama 1996) provide intraspecific variation in life expectancy of workers.
If they are queenless
too long a worker may start laying.
In 4 "queenless
" colonies, the founding queen had been replaced by at least 1 neotenic female 2-6 years prior to this experiment (Long et al.
Of these, eight (= 50%) were queenless
and presumably orphaned.
Cell builder: Honey bees will want to raise a queen(s) when queenless
, and accept prepared larvae to start queen cells.
worker groups have the opportunity to bias the developing brood toward their own interests, and one can compare features of nests within the same colony as a function of whether or not they contain a queen.
(Set one hive, preferably the weaker one, or one that is queenless
, on top of the other, with a sheet of newspaper with a few pinholes between the two.
Five to 10 major and minor workers were selected randomly from both queenright and queenless
nests from each of several mature colonies collected from May through October in 1991.
There is considerable evidence that workers will readily produce males in queenless
colonies (Otto, 1960; Hung, 1973; Pamilo and Rosengren, 1983; Bourke, 1988a, 1988b; A.
