• Immediately before slugs were introduced, the drip irrigation system was removed as it could have provided an escape route for the slugs or beetles.

• Granivores were even able to locate seeds from which dung beetles had removed the surrounding faeces.

• We found an increase in the number of fruits produced when inflorescences were visited by more than one beetle.

• Attention has focused almost exclusively on adult beetles, probably because their larvae are conspicuously missing from tropical foliage.

• However, the present authors tentatively conclude that diving beetles may emigrate due to density-dependent effects when their populations reach certain but unknown threshold levels.

• The availability of alternative prey may have affected the quantities of slug consumed, but clearly did not prevent the beetles from reducing slug populations.

• Marked similarities are reported between complexes of the natural enemies associated with bark beetles in different parts of the world.

• In other words, they enacted (5a) non-causatively, moving the elephant by itself, and enacted (5b) causatively, making the rhinoceros push the beetle.

• The parasitoids rapidly became firmly established and snout beetle populations declined dramatically.

• The bait areas were large enough for all beetles to occur simultaneously.

• Fewer beetles attacked infested trees in subsequent years.

• This served the purpose of identification as well as to approximate the handling given to treatment beetles during ablation of appendages.

• The use of relatively small baits ensured that competition would have occurred even at low beetle densities.

• Consider, for example, the bombardier beetle's extraordinary system of defence.

• The occupancy-abundance relationships established here can be used as guide to estimate beetle densities for decision-making.
