Biological control of weeds in Vanuatu began in 1935, with the introduction of the tinged Teleonemia scrupulosa to control Lantana camara. To date, nine biological control agents have been intentionally introduced to control eight weed species. Seven of these agents have established on their respective hosts while an eighth, Zygogramma bicolorata, an agent for Parthenium hysterophorus has only recently been released and establishment is unlikely.

The purpose of this report is to provide an overview of the various frameworks and initiatives that exist in the Pacific Island Countries and Territories (PICTs) with regards to invasive species management and how they could be utilised towards the development of a coordinated mechanism by the countries in the Melanesian region in addressing biosecurity and invasive species concerns. The terms of reference for this report can be seen in Annex 1. The benefits from a coordinated region may include enhanced economic opportunities and safeguarding the unique ecological systems and species diversity for the wellbeing of the Melanesian people. The PICTs are one of the best organised and well-coordinated regions in the world in terms of environmental management. Comprising thousands of islands, atolls and islets, the Pacific Islands are categorised in many different ways including the three sub-regions of Melanesia, Micronesia and Polynesia (generally in reference to the size and cultural context of the islands and people).
