Exempel på biological control

• An effective host-finding capacity is, however, one of the main determinants of successful biological control.

• However, the amount of research pertaining to biological control of termites using these agents is negligible.

• Their correct identification is fundamental for biological control purposes.

• Biological control agents have also been applied in the management of cruciferous aphids with some degree of success.

• Therefore, it is essential that the effects of these control systems on specific biological control agents are evaluated.

• Supplemental food sources are a useful tool for biological control since they allow greater survival, and potentially reproduction of predators when food sources are scarce.

• Thus, it had the highest impact on the pest and may yet show promise for a biological control initiative.

• Generally, the search for a successful biological control agent should start in the area of origin of the pest.

• Actual abundance of beneficial arthropods was a better indicator of biological control potential than activity estimates.

• This experiment examined the potential of three biological control agents to limit adult sciarid emergence within unspawned compost, spawned compost and casing.

• This is the dominant order among entomophagous insects, both numerically and in regard to their successful use in biological control.

• The results of this work also emphasize the importance of understanding the tritrophic interactions of a system when dealing with biological control.

• The implications of the results of this study for biological control in ornamental crops are discussed.

• 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.

• Such elimination of infestation sources by means of a biological control agent might be more economic than by manual labour.
