Although fruit fly host status determination/designation lies at the heart of strategic decisions
on national and international trade of fruit and vegetables, all attempts thus far to define host …

Research on host specificity testing protocols over the last 10 years has been considerable.
Traditional experimental designs have been refined and interpretation of the results is …

Biological control is a valuable and effective strategy for controlling arthropod pests and has
been used extensively against invasive arthropods. As one approach for control of …

Practitioners of classical biological control of invasive weeds are confronted with a dual
expectation: to achieve successful control of plant invaders and to avoid damage to …

Over 352 herbivore species have now been intentionally introduced into new regions as
weed biological control agents. Recent evidence shows that rapid and significant evolution …

Effective study in the native range to identify potential agents underpins all efforts in classical
biological control of weeds. Good agents that demonstrate both a high degree of host …

Testing the host specificity of potential agents is an important part of biocontrol methodology.
An understanding of the behavioral processes involved in selection of a host plant can be …

Host range in parasitoids could be described by the preference–performance hypothesis
(PPH) where preference is defined as host acceptance and performance is defined as the …

Globally, invasions by alien plants are rapidly increasing in extent and severity, leading to
large-scale ecosystem degradation. Weed biological control offers opportunities to arrest or …

A persistent problem in weed biocontrol is how to reliably predict whether a plant that
supports development in laboratory host-specificity testing will be utilized in field conditions …
