Such elimination of infestation sources by means of a biological control agent might be more economic than by manual labour.
This requires natural enemies to eliminate sparsely distributed patches of prey, so that prey spatial distribution is very relevant to the success of biological control.
The implications of the results of this study for biological control in ornamental crops are discussed.
The results of this work also emphasize the importance of understanding the tritrophic interactions of a system when dealing with biological control.
This is the dominant order among entomophagous insects, both numerically and in regard to their successful use in biological control.
This experiment examined the potential of three biological control agents to limit adult sciarid emergence within unspawned compost, spawned compost and casing.
Actual abundance of beneficial arthropods was a better indicator of biological control potential than activity estimates.
Generally, the search for a successful biological control agent should start in the area of origin of the pest.
