Tests of the effectiveness of rhizobia isolated from several common Acacia species showed significant variation among host populations in plant growth...

Parasitoids often are selected for use as biological control agents because of their high host specificity, yet such host specificity can result in st...

Biological control (biocontrol) of invasive alien plants is a widely utilised weed management tool. Prospective biocontrol agents are typically assess...

Quantitative food web analyses can provide insights into the specificity of consumers such as herbivores, parasites and parasitoids. Understanding suc...

Among saproxylic beetles, many early colonizers prefer particular host species. Ranking of preferred hosts of local saproxylic beetle communities is c...

The seed-to-seedling transition may be a critical stage in determining the dynamics of plant populations. Insects which kill seeds either before or af...

Biological control agents that impact on non-target native species have limited desirability. Aculus hyperici was introduced into Australia to help co...

Results of recent research on Dactylopius opuntiae, a biological control agent for cactus weeds (Opuntia spp.) in South Africa and elsewhere, challeng...

Accurate identification of natural enemies is the cornerstone of biological control, and methods that can separate closely related species are essenti...

The management of bio-invasions relies upon the development of methods to trace their origin and expansion. Cointroduced parasites, especially monogen...
