Phylogeography and host specificity of stemborer parasitoids: essential components for the pre-emptive biocontrol of sugarcane pests in Australia

点击翻译按钮获取中文摘要

Stemboring insects cause huge economic losses to the sugar industry world-wide but fortunately these pests are largely absent from Australia, in part because quarantine measures have prevented their introduction. However, given their proximity, incursion of foreign stemborers from Asia pose a serious threat to Australian sugarcane. To prepare effective pest management plans that can be adopted promptly in a worst-case scenario, this study will 1) develop molecular diagnostic tools to select wasp biocontrol agents that are suitable for the control of specific foreign stemborer pests, and 2) evaluate whether any Australian native wasps have the ability to kill foreign stemborers.
