Termites tunnelled slowly in the dry sand, but diverted their tunnelling into the wet sand once it had been discovered.
An infested tuber was defined as one with visible tunnelling damage, regardless of the presence or absence of larvae.
Of course new food sources will be discovered and the laboratory studies of tunnelling behaviour may yield valuable insights into this process.
The rolling and tunnelling dung beetle species used in this study, were selected for their large size and/or abundance.
For complete methods based on branching, the 'tunnelling' is done by finding nearly feasible points during inspection of the subproblems.
Observations were made as before, and all tunnelling was traced onto the clear plastic sheet.
Termites always chose to explore gaps thoroughly before they began tunnelling in the sand.
Three phases were designated according to tunnelling activity.
