Lagocheirus funestus distribution and impact on cactus biocontrol

Theme: Ecology genetics and evolution, Zoology and wildlife biology 

Description: Lagocheirus funestus is a cerambycid beetle with wood-boring larvae which was introduced into Queensland from Mexico in the 1930’s for the purpose of controlling tree-form invasive cacti. Initial post-release results were promising, with records showing high levels of damage on the weed. However, potentially due to a series of drought years, L. funestus was thought to be extinct from Australia. Recently, two populations of the beetle have been rediscovered in south-east Queensland feeding on Velvet Tree-Pear (Opuntia tomentosa). This project would be mostly field-based and would aim to broaden our understanding of the current distribution, population dynamics, predator interactions, biology, host utilisation and host impact of L. funestus in Queensland.
