Host Test Lists

​​​​​Host specificity testing

Host specificity testing is carried out to ensure that the proposed biological control agent is specific to the target weed or insect pest.

A host specificity test list is a list of plants/insects closely related to the target weed or insect pest that is developed by a biological control researcher. The species on the list are exposed to the proposed biological control agent in a quarantine containment facility.

Biological control agents

​A biological control agent is an organism, such as an insect or plant disease, that is used to control a pest species.

Before a biological control agent is released into the Australian environment, it must be established, via risk analysis, that the risk associated with release is very low or negligible, consistent with Australia’s appropriate level of protection (ALOP).
