Zusammenfassung: | The early life of a leaf-cutter colony is characterized by the dispersal
of a female alate (winged “queen”) carrying a fungal pellet, and the
subsequent establishment of a foundress (workerless “queen”) raising her
incipient fungal garden and colony. The symbiotic roach Attaphila
fungicola hitchhikes on female alates during leaf-cutter nuptial flights,
which strongly suggests that roaches are vertically transmitted to
foundresses and their incipient colonies; however, weak compatibility
between roaches and incipient gardens may constrain roach vertical
transmission. This dataset contains data from an experiment in which
the mortality of incipient fungal gardens and foundresses were scored in
treatments with or without Attaphila roaches. Additionally, in roach
trials we noted whether or not the roaches disturbed fungal gardens during
observational bouts conducted during the experiment (see below for more
detailed description of behavioral observations). Contrary to traditional
assumptions, our results indicate that roaches harm incipient gardens,
suggesting that roaches are not well adapted to use vertical transmission
between colonies. |
